In 1860 Reichenbach described as Stanhopea costaricensis

a Costa Rica orchid which flowered that year with

Consul Schiller at Hamburg. The plant so named was

subsequently lost and the species was known only from

the original diagnosis. Towards the close of 1915 Mr.

C. H. Lankester sent to Kew from Cachi in Costa Rica

some interesting orchids collected by himself. One of

these is a Stanhopea from moist and cool localities

4000 feet above sea-level, which flowered in July, 1916.

It thrives, like other species of the genus, when grown

JanuaRyY—Marcu, 1920,

ina teak basket suspended from the roof of the warm

Orchid House, if provided with abundant moisture in

summer, and kept dry at the root in winter. This

Stanhopea Mr. Rolfe thinks may be the lost species

because under the hypochil of the lip there is a curious

sac whose presence gives this organ a bigibbous appear-

ance. This sac suggests greater affinity between our

plant and the Peruvian S. graveolens, Lindl., than S.

Wardii, Lodd., with which Reichenbach compared S.

costaricensis, There are not many species of Stanhopea in

Costa Rica, and there are few in the genus which have

this sac. Either there are two species in Costa Rica

with this sac, or our plant is identical with the Costa

Rica Stanhopea flowered by Mr. Schiller at Hamburg

in 1860. The original diagnosis does not mention the

coloration or the dimensions of the flowers, and it is

safest to identify provisionally the plant now figured

with the one Reichenbach had in view. In our plant

the sepals are buff-yellow with light red somewhat

ring-like spots and with smaller spots on the petals

and the lip, the latter organ having a pair of dark

red ocular patches on the sides of the hypochil.

Description.—Herb, epiphytic; pseudobulbs clustered, wide ovoid, slightly

angled, olive-green, 14-13 in. long, 1!~13 in. wide, clothed with ovate-lanceolate

firm sheaths, 1-foliate. Leaves long-petioled, elliptic-oblong, shortly acuminate,

plicate, firm, with slightly wavy margin, 10-18 in. long, 8-4 in, wide; petiole

about 3 in. long. Scapes axillary, pendulous, about 5 in. long, clothed with

elliptic-ovate, rather blunt, concave, slightly imbricate sheaths, 2-flowered ;

bracts elliptic-ovate, rather blunt, deep concave, about 1} in. long; pedicels

about 3in. long. Flowers large, showy, pale yellow with reddish-brown spots.

Sepals somewhat connivent,about 8 in. long, the posterior elliptic-oblong, blunt,

concave, the lateral ovate, blunt, deep concave. Petals revolute, oblong, blunt,

with very wavy margin, about 2 in. long. Lip fleshy, deeply 4-lobed, about

3 in. long ; hypochil obovate-panduriform, keeled at the side, invaginate below,

with a rounded mouth and an almost occluded canal; mesochil deeply 2-partite

with falcately incurved acuminate arms; epichil jointed, ovate, rather blunt,

convex. Column incurved, 3 in. long, dilated above the middle; teeth subulate ;

anther obovate ; pollinia 2, obovate-linear ; stipe oblong-linear ; gland scale-like.

Rhododendron ledoides is a charming plant, with the

habit of a Ledum, which belongs to a group of forms, of

which some fifteen are now known, spoken of as the

Cephalanthum series of Rhododendrons. Nearly all of

the members of this series have been discovered by

Mr. George Forrest and Mr. Kingdon Ward. The

headquarters of the group are at very high altitudes on

the ridges which constitute the Tibeto-Yunnan frontier.

BR. ledoides was met with by Mr. Forrest in 1913, at about

13,000 feet above sea-level, on the mountains to the

- north-east of the Yangtze bend, in Lat. 27° 45’ N.,

_ Janvary-Marca, 1920.

where it occurs as a small shrub, two feet high, in open

stony places. Seed received from Mr. Forrest was sown

in spring, 1914, by Mr. J. C. Williams of Caerhays Castle,

Cornwall, who also shared some with Kew. The plants

raised by Mr. Williams, to whom we are indebted for the

material for our figure, flowered with him in 1917. The

flowers, Mr. Williams finds, range from pink to white, and

those that at first are flushed with pink are apt to fade to

white. The plant is not difficult to raise, but, as is the

case with very many species in this genus, there is much

difference between the truss of a well-grown plant such

as the one figured, and that of a badly grown one.

Descriprion.— Shrublet 2-2} ft. high, fastigiately or rather loosely branched,

The North American Winterberry, sometimes also

known in north-eastern America as the Black Alder, has

long been a favourite in English gardens, to which,

according to Aiton, it was introduced for the first time

in 1736. It is found wild over a wide area on the eastern

side of North America, ranging from Nova Scotia and

_ January-Marcu, 1920.

Wisconsin in the north, to Missouri and Florida in the

south. In many parts of this area it is abundant,

preferring low and damp or even swampy situations. Jle

verticillata is the commonest and best known in gardens

of that section in which the leaves are deciduous, of the

genus to which our common Holly belongs. Linneus,

who named it Prinos verticillatus in 1753, and most of the

older writers, indeed regarded these Hollies which are

not evergreen as constituting a genus apart. The

modern view, based on the identity in floral structure

in the two groups, is that Prinos is only a subgenus or

section of //ex, though it is to be noted that the leaves in

Prinos, besides being deciduous, differ also in their mem-

branous texture from those of the A quifolium section, to

which the true Holly belongs. In Prinos, moreover,

the parts of the female flower, though similar in shape and

arrangement, are usually more numerous than in Aqui-

jolium. The nearest ally of J. verticillata is I. laevigata,

A. Gray, the Smooth Winterberry of American writers,

which occurs in the same natural habitats, but can be

readily distinguished from the common Winterberry by

its leaves, which are nearly or quite glabrous, by the

longer pedicels of its male flowers, and by its entire calyx-

lobes, which are not ciliate. Like many other North

American trees and shrubs that affect swamps and damp

places in a state of nature, J. verticillata thrives best in

this country in good well-drained loamy or peaty soil.

There are few more beautiful fruit-bearing shrubs when

it carries an abudant crop of its bright red drupes. But

to secure this result thorough ripening of its wood is

essential, and for this reason the plants must be given a

_ position fully exposed to the south. J. verticillata ean be

propagated either by seed or by cuttings, the latter

being made of leafy shoots, in July. The fruit-bearing

twig figured in our plate was supplied by Messrs Waterer

and Sons of Bagshot in October, 1917, when it happened to

be in bearing and in unusual profusion. The male and

female flowering twigs were supplied from the Kew

collection, where the plant thrives well, but does not

always fruit freely. A variety with yellow fruit, which

Professor Robinson has distinguished as var. chrysocarpa,

is also in cultivation along with other forms that differ

from each other in the shape, texture and pubescence of

the leaves.

Descriprion.—Shrub 8-20 ft. high, usually dioecious ; young shoots glabrous

in the typical form, dark brown, sparingly beset with pale lenticels. Leaves

deciduous, oval, narrowly obovate, or oblanceolate, acute or acuminate, base

cuneate, margin finely and often unevenly serrate or 2-serrate, 13-3} in. long,

3-13 in. wide, glabrous or slightly pubescent above, always pubescent beneath

especially near the midrib, strongly reticulate ; petiole }-} in. long. Flowers

produced in short-stalked axillary umbels, the males 6 or more in a cluster,

the females 1-3 in a cluster. Calyx 5-6-lobed, the lobes ciliate, acute. Corolla

rotate, dull white, ;3; in. across; lobes usually 6, occasionally 7-8; rounded,

obtuse. Stamens usually 6, occasionally 7-8, alternate with the corolla lobes ;

filaments very short; anthers dehiscing longitudinally. Ovary ovoid; cells

usually 6, sometimes 7-8; stigma sessile, stellately 6-8-lobed. Frait a scarlet

globose or ovoid drupe, usually solitary, occasionally in pairs or threes in each

axil, } in. long; stones (pyrenes) compressed, } in. long, 4-6 in each drupe, pale

brown, smooth, bitter.

Cornus Kousa, originally found in Japan on the moun-

tains of Kiusiu and of Nippon, has a wide distribution in

north-eastern Asia, for it has since been discovered in

Corea and in China. The plant from which the material

for our figure was obtained was received at Kew from the

Arnold Arboretum in 1910, where it had been raised from

seed collected by Mr. E. H. Wilson in western Hupeh

three years previously. Wilson has reported that he

found it abundant both north and south of Ichang, at

altitudes of from 4000 to 7000 feet, both as a shrub

and as a small, flat-topped tree, fifteen to thirty feet in

January-Marcu, 1920,

height. ‘He has stated that the fruit is edible. This

species, along with the evergreen C’. capitata, Wall., of

the Himalayas, constitutes the Asiatic subgenus which

Lindley recognised as the genus Benthamia. This group

is characterised by the large corolla-like involucre and

more especially by the coalescence of the fruits into a

fleshy strawberry-like mass. This latter feature distin-

guishes the two constituent species from (. florida, Linn.,

figured at t. 8315 of this work, and (. Nuttalli7, Audubon,

figured at t. 8311, which together form the subgenus

Benthamidia, Spach. These latter two also have a large

showy involucre, but in both the fruits remain free and

both are confined to North America. (€. Kousa flowers

in May and thrives very weli in the British Isles, over

the greater part of which it should be quite hardy. It

has never suffered from cold at Kew. It likes a deep

well-drained, loamy soil and a sunny position. It is less

sensitive to injury by late spring frosts than ©. florida is,

and when in flower may be described as one of the most

beautiful as well as remarkable of hardy shrubs. It

varies a good deal as regards the size of the involucre and

the Chinese form introduced from Hupeh, which is fig-

ured here, has the largest and most striking bracts of any

we have seen in cultivation, though among the fine series

of specimens from Japan preserved in the Kew her-

barium there are some with bracts quite as large as those

of this Chinese plant.

Description.— Tree up to 30 ft. high, or a shrub, young branchlets glabrous

or glabrescent. Leaves deciduous, opposite, ovate, oblong or suborbicular,

apex acuminate, base rounded or broadly cuneate, margin entire, 1-4 in. long,

The handsome Chinese Rhododendron here described

was first met with by the Abbé Soulié in 1893 in the forests

of Tongolo and in the vicinity of Ta-chien-lu in Western

Szechuan and was characterised two years later, under

the name Shododendron lucidum, by the late Mr.

Franchet. The author in so doing had overlooked the

fact that, forty years earlier, Mr. Nuttall had described a

very different Himalayan species under the same name.

Five years later, however, having discovered his over-

sight, Mr. Franchet substituted for the Chinese plant the

January—Marcg, 1920,

name £2. vernicosum now employed. A decade later seeds

of £. vernicosum were secured by Mr. E. H. Wilson for

Messrs J. Veitch and Sons, and the material for our plate

came from a plant purchased by Kew from Messrs Veitch

in 1908. It has been fully realised in English collections

that this is not R. lucidum, Nutt., but this has been

counterbalanced by the belief that Soulic’s species is a

variety, var. /ucidum, of another Chinese Rhododendron

described by Lindley in 1859 as R. Furtunei, T. Moore.

The flowers of the true &. Fortune’ differ much from

those of the Szechuan plant; they lack the fragrance

and do not exhibit the crumpled appearance characteristic

of the opening blooms of &. Fortunci. The smaller leaves,

unequally rounded at the base, and the shape of the

corolla-tube are also distinguishing features. Since the

collection of F. vernicosum by Mr. Wilson, the species has

been found again by Mr. G. Forrest in North-West

Yunnan, where it grows on the borders of pine forests on

the eastern flank of the Li-chiang range at about 11,000

feet above sea-level, as a spreading shrub sometimes

fifteen feet in height. The species is perfectly hardy

at Kew and thrives in peaty soil or sandy loam free

from lime. It prefers a position where it is protected

from the rays of the mid-day sun.

Description.—Shrub of spreading habit, in a wild state up to 15 ft. in

height; twigs cylindric, dark brown, glabrous, somewhat polished when dry,

+ in. thick in their second season. Leaves laxly arranged, elliptic, wide

rounded and bluntly mucronate at the tip, unequally rounded or nearly

truncate at the base, 23-43 in. long, 1-2} in. wide, thinly leathery, green and

usually polished above, paler and finely closely reticulate beneath, glabrous on

both surfaces, midrib narrowly channelled above and raised beneath, lateral

nerves 14-16 along each side the midrib, which they leave at a wide angle,

slender, much branched and disappearing towards the leaf-margin ; petiole

{-i} in. long, glabrous, narrowly channelled above, Inflorescence terminal,

about 10-flowered ; bracts densely villous, quickly deciduous; pedicels nodding,

4-1} in. long, beset with small subsessile viscid glands. Calyx very short,

about 7; in. long, unequally 5-lobulate ; lobules wide ovate, beset outside with

shortly stipitate glands. Corolla pale rose, wide tubular-campanulate; tube

1 in. long, glabrous; lobes § in. long, 2 in. wide, shallow emarginate. Stamens

12-14, shortly exserted; filaments glabrous ; anthers yellowish-brown, } in.

long. Ovary 6-17-celled, densely clothed with almost) sessile glands, slightly

suleate; style longer than the stamens, pale green, 1} in long, beset with

minute reddish short-stalked. viscid glands, crowned by the lobulate stigma.

This attractive heath, a new species of the small]

section Lurysteygia of the subgenus Chlamydanthe, as

defined by Guthrie and Bolus in the Flora Capensis, was

discovered by the late Professor H. H. W. Pearson on the

Cederberg Range in the Clanwilliam Division, and seeds

_Janvary—Marcu, 1920.

were sent by him to Kew from the National Botanic

Garden, Kirstenbosch, in 1915. One of the plants raised

from these seeds has now reached a height of about

eighteen inches and fiowered in a greenhouse in January,

1919. Its flowers are rather large and effective, and

should the plant prove floriferous it will be a welcome

addition to the number of winter-flowering heaths in

cultivation. Among the Cape species of Lica already

described, now nearly 500, /. Haroldiana (named after its

discoverer, who is also commemorated in the genus by F.

Pearsoniana, L. Bolus) is clearly most nearly allied to L.

nobilis, Guthrie and Bolus, a little-known plant which, like

that now described, is found on the Cederberg Range. It

may, however, easily be distinguished by the characters

mentioned above. /. Monsoniana, Linn., of which the

variety exserta, Klotzsch, is figured at t. 1915 of this

Magazine as E. Monsoniae, is also an ally, but, particularly

when young, its branches are covered with a floccose

pubescence, its much shorter leaves are ciliate, and its

flowers terminate very short lateral branches arising

below the tips of the shoots. £: glauca, Andr., figured

at t. 580 of this work, is a pretty species belonging to

the same section, but quite distinct. Other Ericas re-

corded from the Cederberg Range are /. verecunda, Salisb.,

EE. Thunbergii, Montin, and £. inflata, Thunb., all ob-

viously different from /. Haroldiana, though F. inflata

resembles it in habit, umbellate inflorescence, and some-

what in the corolla which, however, is smaller, while the

calyx and bracts are quite dissimilar. /. /aroldiana

seems to be quite happy and is making good growth,

under the cool greenhouse treatment accorded the other

members of this genus from 8. Africa.

Description.—Shrub 1} ft. high or somewhat taller, erect, much branched ;

twigs erect, rigid, densely leafy, pale brown, glabrous. Leaves ternate, very

shortly stalked, at first erect, at length spreading, linear-subulate, including

the petiole from }—4 in. long, usually about 4 in. long. ,,-;; in. wide, shortly

The Primula here figured is a native of North-west

Yunnan where it was first discovered by Mr. F. Kingdon

Ward in June, 1913, on precipices above a glacier two

days’ journey to the west of Atuntsu, at an altitude of

11,000 feet above the sea. Mr. Ward notes that the

species, which has been described by Professor Bayley

Balfour and himself as P. pulvinata, occurs naturally in

large tufts, and Professor Balfour speaks of it in culti-

vation in the Royal Botanic Garden, Edinburgh, as a

dainty cushion-plant. The figure now published has

been prepared from a living plant kindly forwarded for

the purpose by Professor Balfour. It was raised in the

Edinburgh garden from the seeds supplied by Messrs.

Bees, Limited, to whom they had been communicated

from Yunnan by Mr. Ward. At Edinburgh where the

_ January-Marcu, 1920,

species has been grown in pots as well as planted out

under glass in a house devoted to rock-plants, P. pulvinata

has proved easy to cultivate at all stages. It does not

appear to be fastidious as to soil; a good loam with a

liberal supply of broken limestone or crushed potsherds

and sand gives satisfactory results. It is not yet possible

to say from experience that it will prove entirely hardy

out of doors, but in the cold greenhouse it has withstood

fifteen degrees of frost without suffering damage. Being

evergreen, growth appears to goon during the whole year.

Mr. Harrow, to whom through Professor Balfour we are

indebted for this information, regards it as probable that

the best hope for success out of doors will be where the

plant is grown in a situation where the water, of which it

requires at all seasons a fair amount, can drain away

quickly from the collar and roots, At Kew the plant has

been accorded the treatment suitable for P. Forrestii with

satisfactory results. The great difficulty, as Professor

Balfour points out, with the Primulas of this group,

and the circumstance that militates against their satis-

factory cultivation as garden plants, is winter damp.

These species show a crisp type of withering of their

leaves, and while they can resist a moderate amount of

top-water, cannot live if their withering leaves become

sodden.

Descriprion.—Herb, forming dense cushions; individual plants dwarf,

devoid of mealiness, softly clothed with viscid distinctly stalked glands.

Leaves long-petioled, lanceolate, blunt at the tip, gradually narrowed to the base

into the winged petiole, up to 23 in. long, over 4 in. wide, with crenulately

wavy margin, papery, somewhat bullately veined and glandular-puberulous

above, pilose beneath, lateral nerves somewhat raised, about 6 on each side the

midrib; petiole about } in. long, 1 in. wide, 1-nerved, towards the base straw-

coloured and somewhat translucent. Peduncle nearly 2 in. long, 2-3-flowered,

densely glandular-puberulous ; bracts lanceolate, acute, over } in. long ; pedicels

The striking Campanulaceous species now figured was

first described by Mr. Nakai in 1909 as a Symphandra.

Two years later its author came to the conclusion that it

represents a distinct genus which he named //anabusaya.

In the work in which this revised view is stated Mr. Nakai

does not lay emphasis on the points by which it may be

distinguished from Symphandra and, as we have failed to

detect any such, we have here employed his original name,

S. asiatica. Perhaps the most remarkable feature con-

nected with this Corean plant is its geographical isolation.

The other species of the genus Symphandra are contined

to South-eastern Europe, the Caucasus, Armenia, Lazistan

January—Marcu, 1920,

and northern Persia, and the species to which the Corean

S. asiatica is most closely related is the Candian S. eretica,

A.DC., one that has long been known. For the mate-

rial from which our plate has been prepared we are

indebted to Mr. G. W. E. Loder, who received seed of the

species collected by Mr. E. H. Wilson in Corea. This seed

was sown in two pots, in March, 1918, and flowered in a

cool house in Mr. Loder’s garden at Wakehurst Place,

Ardingly, Sussex, during June and July, 1919. One of

these pots with seedlings, some of them in flower, was

presented to the Kew collection by Mr. Loder and en-

abled the figure now supplied to be made. So far the

hardiness of the species has not been put to the test of

cultivation in the open.

The Rubiaceous genus /avetta is restricted to the

Eastern hemisphere, five-sixths of the species being

confined to the tropical regions of south-eastern Asia and

Africa, the remaining sixth occurring in South Africa.

Among the members of the South African group of

species one, ?. caffra, Linn. f., an old and long known

plant in European collections, has been figured at t.

3580 of this work. The plant now figured is one of the

Tropical African species, which is a native of Abyssinia

and Uganda, where it grows in the warm zone on the

lower slopes of the mountains. This species was first —

met with by Mr. Henry Salt during his travels in the

JaANUARY—Marcu, 1920.

interior of Abyssinia in 1809-10 on behalf of the British

Government. Dr. Robert Brown, who identified the

plants collected by Salt, named this one P. congesta. Un-

fortunately no description of the species was published

at the time, and when the plant was met with again by

Dr. Riippell, who found it on the way from Halei to Tem-

ben in Abyssinia, it was in 1837 for the first time de-

scribed by Fresenius from Riippell’s specimens as P. abys-

sinica. In 1916 the plant was sent to Kew from Kam-

paia in Uganda, where it is also wild, as a species of

Clerodendron; for its introduction to ¢ultivatiom we are

indebted to the Agricultural Department of the Govern-

ment of Uganda. Nearly three years later it flowered in

February, 1919, in a tropical house at Kew, and thus

provided material for the preparation of our plate. It

has thriven well under the conditions suitable for the

Indian species of /zora and Pavetta, and had reached a

height of six feet before it flowered. As in the case of

the Indian species of Pavetta, the flowers of P. abyssinica

are very fragrant.

Description.—Shrub, 6-8 ft. high; twigs pale grey, villous at the joints.

Leaves obovate-elliptic, bluntly acuminate, cuneate at the base, usually about

6 in. long by 13 in. wide, but sometimes 9-10 in. long by 4 in. across, margin

The very large and natural Orchidaceous genus

Pleurothallis contains relatively few species that can be

regarded as valuable from the standpoint of the orchid

grower. The species here figured, P. punctulata, may be

included among those worthy of a place in a good

collection, even if its claims on aesthetic grounds are

not of a high standard, owing to its rarity. To a place

in the pages of this Magazine it is fully entitled because

of its considerable botanical interest. It seems to be

unique in the genus Pleurothallis for the glaucous hue of

the leaves, due to a dense coating of greyish-white

farina. It is also curious on account of a characteristic

twist at the base of the petiole, the effect of which is to

bring the solitary flower opposite the under-surface of

the leaf. This feature was alluded to when the species

was first described by Mr. Rolfe, now thirty years ago,

but was then cautiously adverted to as possibly an

accidental circumstance. The experience of a generation

January—Marcu, 1920. :

shows that the character is as constant as it is peculiar.

There are other features of an anomaious nature which

tend to render the affinity of our plant doubtful. While

it is, as Mr. Rolfe points out, most comparable with the

Colombian P. inflata, Rolfe, a species certainly referable

to the group Macrophyllac-Fasciculatae as defined by the

late Professor Lindley, the plant figured produces a soli-

tary flower from a large spathe like that in the natural

section Spathaceae. Yet it differs essentially from the

true members of that section, in all of which the flowers

are disposed in many-flowered racemes. The history of

P. punctulata is simple, so far as it goes. The species

flowered for the first time in cultivation in December,

1888, with Messrs James Veitch and Sons, Chelsea, and

was then submitted to Kew for identification with the

information that it had been imported, as a solitary

plant, from New Granada, three years before. Shortly

thereafter, the plant passed into the collection of

Mr. R. I. Measures of Camberwell, with whom it flowered

in December, 1802. No other plant of the species is

‘known to have been imported, and no wild specimen has

been met with in herbarium collections, so that the

precise habitat of P. punctulata in Colombia is still

uncertain. In, February, 1908, a small portion of the

original plant, secured by division, was presented to the

Kew Collection. This plant has thriven well in a cool

house under the conditions suitable for species of

Masdevallia, and came into flower in November, 1918,

when our figure was made.

Description.—Herb, epiphytic, 5-6 in. high. Stems nearly cylindric, rather

slender, 2-3 in. long, clothed halfway up with narrow tubular sheaths, 1-foliate.

The very interesting Ailes figured here was discovered

by Mr. E. H. Wilson in Western Szechuan in July, 1903,

and was collected by him again near Ta-chien-lu in 1904.

According to the Plantae Wilsonianae it was found by the

same collector in 1908 and in 1910 in various other

JaNUARY-MarcH, 1920.

localities, all in Western Szechuan. The shrub, which

attains a height of six to nine feet and is notable on

account of its sometimes red and at other times orange

glandular fruits, occurs in woodlands and thickets up to

an elevation of 9400 feet above sea-level. The plant

was first introduced to cultivation, from Mr. Wilson’s

earlier seeds, by Messrs James Veitch and Sons, and in

1915 a flowering branch stated to be of Chinese origin

and to represent one of Mr. Wilson’s plants (958a) was

submitted to Kew for identification by Colonel S. R.

Clarke of Borde Hill, Cuckfield, Sussex. The spray sent

was readily identified with Mr. Wilson’s plant of the

1903 collection (3759) and Miss Jesson, who established

this fact, regarded it as a very distinct variety of Ribes

Maximowiczii, Bat., a species discovered by Mr. Potanin

in Eastern Kansu, which is characterised by its short

extremely compact fruiting racemes, with the individual

fruits closely covered with coarse bristles. The affinity

between the two shrubs is indeed extremely close, but the

additional material now available shows that it is more

_ Satisfactory to regard Miss. Jesson’s variety as a separate

species, readily distinguished by its much elongated

inflorescences with more numerous flowers and especially

by the much shorter and less plentiful glandular bristles

which cover the berries. Professor Janczewski, who has

included the Szechuan plant now described in the species

from Kansu which Batalin named 2. Maximowiczii, only

knew the latter in the fruiting condition, and, although he

Placed it in the section Berisia, was disposed to believe

that it may really belong to his section Parilla. There

seems now no doubt, however, that the arrangement

actually adopted by Janczewski is correct, for the plant

now figured as RF. Jessoniae and named in compliment to

the lady who first indicated the differences between it

and the plant from Kansu, is certainly a member of the

section erisia, which. differs from Parilla in having

erect in place of pendent racemes, in having no ovules in

_ the female flowers and in having no pollen in the reduced

anthers of the male flowers: in Parilla the male flowers

have sterile pollen and the female have sterile ovules.

The material for our plate has been derived, as regards

the male inflorescence, from a plant in the collection at

Kew; for the female inflorescence and the fruit we are

indebted to the kindness of Mrs. Berkeley of Spetchley

Park, Worcester, in whose garden they were produced.

It is to be noted that as they ripen in this country the

fruits are of a pale rusty yellow colour, not orange or

red as they are in Szechuan. At Kew the shrub is

perfectly hardy and thrives well in loamy soil. It can

be increased readily by cuttings. The section Berisia to

which it belongs contains seventeen species, most of them

Chinese, though it includes also the well-known &. alpi-

num, Linn., a native of Europe and Northern Asia.

Description.—Shrub, 6-9 ft. high, branching freely, unarmed, dioecious ;

twigs of the first season thinly pubescent and sparingly glandular-setulose ;

bark of older twigs brown or tawny, cracking longitudinally. Leaves variable

in shape, more or less ovate, wide, more or less truncate or often slightly

cordate at the base, usually more or less 8—5-lobed, the lobes often shallow,

rarely absent, the margin at the same time coarsely twice serrate, 2}—4 in. long

and broad, sparingly beset with short hairs above, softly hairy beneath

especially on the nerves; petiole 3-12 in. long, laxly hirsute and at the same

time glandular-setulose. Racemes 5-6 in. long, at the tips of short flower-

shoots, erect or somewhat nodding, but assuming an apparently lateral position

as the flower-shoot elongates ; bracts lanceolate, acute, 1-} in. long, pubescent

and sparingly glandular; pedicels 4-1 in. long, also pubescent and glandular.

Male flowers saucer-shaped. Receptacle 3, in. long, pubescent and glandular .

at the base. Calyx deep tawny red; lobes rather rounded, ;);—} in. long.

‘Petals minute, spathulate-unguiculate, the claw linear, the limb ,, in. across.

Stamens 3, in. long; filaments slightly dilated at the base. Styles of the

imperfect ovary ;; in. long, connate at the base, as long as the petals. Female

flowers resembling the male, but with the receptacle of the inferior ovary ovoid,

finely villous and densely clothed in addition with glandular bristles 3 in. long,

with the anthers reduced to tubercles adnate to the receptacle and with the

styles, which are connate half way up, longer than the petals. Frwit ovoid

globose, over } in. in diameter, tipped by the persistent female flower, red or

reddish-yellow, clothed with white hairs, and in addition with a sparse covering

of glandular bristles over } in. long. Seeds obovate-elliptic in outline, nearly

The new Rhododendron here figured was received as a

seedling from the Jardin des Plantes at Paris in 1889,

under the name /. decorum, Franch., and was raised there

from seed sent by Delavay from China where . decorum

is. a native plant. There are, however, many differences

_ Aprit-JuneE, 1920,

between the species described by Mr. Franchet and that

now described as R. serotinum. The latter is of long and

straggling growth, a feature so marked in one of the two

healthy plants grown in the Himalayan House at Kew,

that it admits of being trained up one of the pillars

which support the roof. This character, the fact that

the leaves are unequally cordate at the base, and the

circumstance that the corolla outside is beset with many

bottle-shaped glands are marks that at once distinguish

RR. serotinum from R. decorum. From R. Fortunei, Lindl.,

another close ally and a member of the same natural

group, . serotinum differs especially by its hairy

filaments. From both species mentioned £. serotinum

may be distinguished by its blotched corolla, an unusual

feature in the group to which all three belong. Out of

doors /. serotinum was grown for a number of years in

the Rhododendron Dell at Kew, and appeared to be

perfectly hardy. But save when in flower it was

principally remarkable for its gaunt sparsely branched

habit, and when the stem was at last broken off at

ground-level during a gale, the plant was not replaced.

If space can be found for it in a collection it nevertheless

is not unworthy of a place, for the flowers are handsome

and delightfully fragrant, and they exhibit one feature

that cannot but appeal to growers of Rhododendrons.

Even under the protection of the Himalayan House the

species does not begin to flower until well into August,

and continues to produce blossoms from then till the

end of October. In the Kew plants the leaves exhibit

three or four parallel impressions on each side of the

midrib, perhaps the consequence of their disposition in

the bud stage.

DEscriPTion.—Shrub, up to 10 ft. high ; branches long and lax; other twigs

yellowish-brown, smooth, polished ; young shoots green, polished, marked with

minute pale lenticels. Leaves oblong-elliptic, base slightly and unequally

cordate, apex rounded, retusely mucronate, 4-6 in. long, 1}-13' in. wide,

glabrous, dull green above, glaucous-green beneath, conspicuously reticulated

and finely papillose, the papillae very short, suborbicular, not quite in contact

along the veinlets but dense and crystalline between the veinlets; lateral

nerves about 15 on each side of the midrib, from which they diverge at an angle

of 90°, much branched towards the leaf-margin, distinct on the under surface ;

petiole 3-1} in. long, glabrous, nearly cylindric, about in. thick. Inflorescence

For the introduction to English collections of the

remarkable New Guinea species of Bulbophyllum now

figured, orchid growers are indebted to Messrs. Sander

and Sons, St. Albans, by whom it was publicly exhibited

in July, 1915, under the name B. Balfourianum. The

plant in question thereafter was added to the collection

of Mr. H. T. Pitt, Rosslyn, Stamford Hill, to whose

courtesy we are indebted for the material for our plate

which was kindly supplied when the plant was in blossom —

in June, 1919. The name under which the species has

thus found its way into cultivation is not, however, one

that can be sustained since the species was discovered

during the second Lorentz Expedition to New Guinea,

was afterwards in cultivation in the Buitenzorg Botanic

Garden, and was there adequately described as B. macro-

bulbum by Mr. J. J. Smith. When publishing this

account, Mr. Smith referred the species to the section

Sestochilos, but it has since been treated by Mr. Schlechter,

who met with the plant again in North-eastern New

Guinea, as the type of a distinct section, Macrobulbum.

The species is remarkable for its very glaucous leaves,

a character wherein it agrees with the allied B. Fletcher-

ianum, figured at t. 8600 of this work as Cirrhopetalum

Fletcherianum, Rolfe. The individual flowers bear some

resemblance to those of Cymbidium Huttonii, Lindl,

figured in this magazine at t. 5676. In cultivation it

calls for the tropical treatment suitable for other species

of the genus.

Description.—Herb, epiphytic, glaucous; pseudobulbs clustered, ovoid,

stout, bluntly angled, 2-3 in. long, 14-2} in. wide, dull olive-green with pale

blotches, at length wrinkled, 1-foliate. Leaves thickly leathery, recurved,

oblong or narrow-oblong, blunt, 7-8} in. long, 2-2} in. wide, glaucous green,

pruinose beneath, margin and midrib faintly purple, narrowed to the base.

Racemes axillary, much contracted, clustered at the bases of the pseudobulbs,

4-5-flowered ; bracts wide ovate, concave, $—-1in. long, acuminate and recurved

at the tip; pedicels about 2 in. long. Flowers large, fleshy, odour unpleasant,

yellowish-white with purple lines and blotches, the lip and the bases of the

petals blood-red. Sepals about 13-13 in. long; posterior obliquely erect,

ovate, very acuminate, concave; lateral obliquely ovate, foliately recurved,

acuminate. Petals clawed, ovate, subacute, undulate, under 1 in. long. Lip

recurved, fleshy, elliptic-oblong, rather blunt, } in. long; disk sulcate, warted.

floheria populnea was originally discovered by Mr. C.

Fraser in 1825, and again by Mr. R. Cunningham in

1833. Upon their specimens Mr. A. Cunningham

founded the genus in 1839, adapting for it the native

name for the tree, “ houhere’’ or “ hoihere.”’ It occurs

in both the North and South Islands of New Zealand.

The genus is closely allied to Plagianthus, which differs

from //oheria in the often unisexual flowers, the linear

decurrent stigmas and the solitary carpels. 7. populnea,

like so many New Zealand trees, is extremely variable,

and whilst most authorities follow Sir J. D. Hooker in

regarding the various forms as belonging to one species,

others look upon them as constituting three or four

APRIL-JUNE, 1920,

closely allied species. The differences are chiefly in the

size and shape of the leaves, in the size of the flowers,

and in the number of flowers in each fascicle. Mr. Kirk

observes that the transition of one variety to another

is so gradual that it is impossible to define lines of

separation. The form now figured we regard as most

nearly approaching Hooker’s var. lanceolata, which differs

from his var. vulgaris in its lanceolate leaves and smaller,

fewer flowers. In var. vulgaris some leaves are as much

as five inches long by two and a half inches wide. Ina

third variety (angustifolia, Hook. f.) many leaves are only

an inch iong by one-third of an inch wide. The most

curious exhibition of heterophylly is, however, seen in

occasional basal and apparently sterile shoots which

bear leaves shaped like those of Hawthorn, many of

them only from a quarter to half an inch long. Near

London the Hoheria needs greenhouse or at least wall

protection. It is hardy further south and along most of

our western seaboard. The material for our figure was

kindly furnished by Mr. R. Windsor Rickards, Usk

Priory, Monmouth, to whom it had been given by

Mr. H. A. Tipping, Mountain House, Chepstow, in whose

garden it flowers in August. It is also cultivated in the

gardens of Cornwall, Devon, Scilly Isles, etc., where it is

one of the most graceful and attractive of Jate-flowering

trees. It thrives in loamy soil and can be propagated

by cuttings.

Description.—Tree of small size, 10-80 ft. high, and graceful habit, or a

shrub ; young shoots covered with a grey stellate pubescence. Leaves alternate,

persistent, lanceolate to ovate-lanceolate, acuminate at the apex, cuneate at the

base, coarsely and irregularly dentate, teeth slender; the blade 1-4 in. long,

3-1} in. wide, glabrous or with very scattered stellate pubescence beneath, rich

lustrous green above ; petiole }-} in. long, stellately pubescent. Flowers in

fascicles, produced during late summer in the leaf-axils of the current season’s

twigs, {-1 in. diameter. Calyx grey-pubescent, turbinate, 5-lobed, the lobes

triangular, acute, 3; in. long, reflexed at the fruiting stage. Petals 5, snowy-

white, oblong-obovate, often unevenly lobed towards the apex, 2-1 in. long,

? in. wide. Stamens numerous, arranged in 5 bundles, those of each bundle

united below into a short column, separating above into slender filaments ;

anthers yellow. Ovary usually 5-celled, ovules solitary in each cell; stigmas 5,

capitate, Fruit consisting of 5 winged carpels attached to a central axis;

wings membranous, obliquely obovate, } in. long, pinkish, and furnished with

The handsome /ris here figured is a native of Turkes-

tan, for the introduction of which horticulture is indebted

to Mr. C. G. van Tubergen, the younger. Its earliest

appearance in cultivation in this country dates from

1913, in which year rhizomes reached the garden of

Mr. W. R. Dykes at Godalming, where it flowered for

the first time in 1916, and whence the material for the

present plate was contributed by Mr. Dykes in May,

1919. When describing the species on the occasion of

its first making blossom, Mr. Dykes pointed out that it

is a member of the section /egeliana, in foliage closely

resembling /. Korolkowii, Reg., from Turkestan (figured

at t. 7025 of this work), and /. stolonifera, Maxim., from

Aprit-JUNE, 1920. :

Kokan, two well-known species of the same group, with

rootstocks that spread even more rapidly by stolons

than the former, though hardly to be distinguished, when

in a dormant condition, from those of the latter. This

new /ris Mr. Dykes has dedicated to the Messrs. Hoog,

nephews of its introducer, and now the heads of the

famous establishment at Haarlem whence it was received

by him. Like other members of the same section as

I. Hoogiana, Mr. Dykes finds that its rhizomes, if they

are to remain firm and plump, should not be taken up

before the middle of July. One of the more pronounced

features of this /ris is the uniform colouring of all parts

of the flower, with the exception of the rich golden-

yellow beard. The general colour is lavender in the

fully opened flower, though the shade appears to vary

slightly, and in his original account of the plant Mr.

Dykes states, on the authority of Mr. Hoog, that white-

flowered specimens occur in the original stock.

Description.—Herb with the rhizome emitting numerous stolons which are

often of considerable length. Leaves ensate, slightly curved, somewhat blunt,

14-18 in. long, up to ? in. wide, glaucous-green, smooth. Stem about 20 in.

high, 2-3-flowered at the top. Spathes herbaceous, green except at the tip and

along the upper portion of the membranous margin where they are flushed with

purple, sharply keeled, 24-3} in. Pedicels very short. Perianth-tube green,

streaked with purple, about 1} in. long, reaching the top of the spathe ; outer

segments with a reflexed rounded-obovate quite blunt, uniformly clear lavender-

violet limb, 1} in. long, 1} in. wide, and with a wide cuneate claw 1} in. long,

of a paler lavender, indistinctly veined at the sides, beard copious, golden

yellow, extending almost for 1} in. somewhat beyond the claw on to the limb,

where it becomes thinner and ends abruptly ; inner segments erect, with an

obovate somewhat acute limb gradually narrowed downwards to a short rather

narrow claw, including the claw over 3 in. long, 1} in. wide, uniform in colour

with the outer segments, beard scanty, golden yellow, extending about 1 in.

Anthers slightly longer than the filaments, pale in colour, with whitish pollen.

Ovary oblong, 1-1} in. long; style-arms wide-oblong, lavender; crests with

broadly semi-ovate, almost entire lobes. Capsule elongated, narrowed to the tip.

Seeds pyriform, brown, rugulose, with a conspicuous whitish aril.

The Composite genus Venidium, established by Lessing

in 1831, includes some five and twenty species, all of

them natives of South Africa. It is closely allied to

Aretotis, a genus recognised by Linnaeus, and has, in

fact, been united therewith by authorities so competent

as Hoffmann and Beauverd. Bentham, however, relying

on characters derived from the achenes and the pappus,

has followed Lessing and Decandolle, and Mr. Hutchinson,

‘who has prepared the description that precedes this note,

finds himself, after a critical scrutiny of the species of

this and other allied genera, able to confirm the validity

of the conclusions arrived at by Bentham. The absence

Aprit-June, 1920.

or extreme reduction of the pappus in Venidium renders

its separation from Arctotis as easy as it is essential. The

beautiful species now figured shares with a number of

other Compositae that possess large and showy flower-

heads the popular name “Gouws bloem.” It has been

determined, from the original description, to be the

species named by Decandolle V. macrocephalum, which

would appear to be extremely rare, for the only previous

record of its collection is that by Drége, who found it

in South-west Africa, between Kaus and the Orange

River. The plant figured was raised at Kew from seed

sent from Pretoria by Dr. I. B. Pole Evans in the

spring of 1918. It flowered in August of the same year,

but unfortunately failed to ripen its seeds at Kew.

Description.—Herb with a simple annual 1-flowered stem, 1} ft. high,

sparingly pubescent throughout with many-celled hairs, sparsely leafy low

down, Leaves nearest the ground long petioled, lyrately pinnately lobed,

6-8 in. long, those higher up sessile, elliptic or oblong-elliptic, rounded or

subtruncate at the base, blunt at the tip, 13-2} in. long, 2-1} in. wide, papery,

up to 3 in. long. Heads about 3 in. wide; involucral bracts 3-4-seriate, the

outer loose and narrow, the inner close-set, wide lanceolate, acute, long ciliate

and gradually longer from without inwards. Receptacle slightly convex, # in.

across, fimbrillate. Ray-florets yellow with reddish base, obscurely 2-seriate ;

tube of the corolla 3 in. long, sparingly pubescent; limb narrow lanceolate,

The Myrtaceous genus Metrosideros is widely distributed

throughout Polynesia and is well represented in New

Zealand. The species now figured, J. collina, though

not one of the New Zealand members of the genus, is

most nearly allied to J/. tomentosa, A. Rich., known in

New Zealand as the Christmas Tree and figured at

t. 4488 of this work. The history of our plant is some-

_ what complicated, a circumstance attributable partly to

its very wide distribution, partly to the variability it

displays. It was first briefly characterised by Forster

Aprit—June, 1920.

in 1776 as Leptospermum collinum, from specimens the

exact provenance of which is unknown, and was diagnosed

by him a second time as Melaleuca aestuosa, from Tahiti

material. Later this species was united with the

Hawaiian Metrosideros polymorpha of Gaudichaud, now

reported from many other Polynesian groups. Recently,

however, Mr. J. F. Rock, Government Botanist of the

Sandwich Islands, after a careful study of the Hawaiian

Metrosideros, has reached the conclusion that M. poly-

morpha includes five species, four of these being endemic

in the group, while the fifth is the widespread MW. collina.

But Mr. Rock finds further that in the Sandwich Islands

M. collina itself includes eleven recognisable varieties,

nine of which are endemic, while the remaining two,

var. glaberrima and var. incana, are distributed. The

form recognised as var. incana is, however, at once the

Linnaean Melaleuca villosa and the original Leptospermum

collinum of Forster which we now figure: This particular

form extends from Lord Howe Island and New

Caledonia eastward to Pitcairn Island and Tahiti and

northward to Hawaii. For the introduction of M. collina

to European gardens, horticulture is indebted to Major

A. A. Dorrien-Smith, from whose garden at Tresco

Abbey, Isles of Scilly,.came the material for our figure.

To Tresco Major Dorrien-Smith brought his plant from

‘Wellington, New Zealand, whither it had been introduced

from Sunday Island in the Kermadec Group by Mr.

R. B. Oliver. It thrives satisfactorily in the Scilly

Islands, where it flowered in June, 1918, and may prove

hardy in other especially favoured situations in the

south-west of England and Ireland.

Description.—T ree, up to 60 ft. high, or at times a shrub; branches terete,

at first usually hairy, ultimately becoming glabrous. Leaves opposite, shortly

stalked, leathery, obovate, wide elliptic or nearly orbicular, blunt at the apex,

The Chinese lily now figured is a member of the

Martagon group of the genus Lilium, raised by Major

F. C. Stern, at Highdown, Goring-by-Sea, Sussex, from

seeds received by him from China in 1915, from

Mr. Reginald Farrer, with the indication that this —

particular batch consisted of ‘‘a mixed lot of poor seed

Aprit-JuneE, 1920.

of undecipherable small lilies.” Whatever the other

components of this seed-packet may prove to be, it is

interesting to know that of the species included therein

one proves to be new to cultivation and to science, and

possesses intrinsic merits that justify its dedication to

the distinguished traveller and cultivator to whose

efforts its introduction to our gardens is primarily due.

In the Martagon group, our plant, which has been figured

from material placed at our service by Major Stern, is

clearly a near ally of LZ. Duchartrei, Franch., figured at

t. 8072 of this work. The features which especially

characterise L. /urreri are its linear-lanceolate cauline

leaves which are disposed throughout the greater part of

the stem, and its relatively small flowers whose revolute

perianth-segments are white with dark purple spots. In

the lower portion of the flower these segments converge

to form a tube under half an inchin length. The flowers

are very strongly but pleasantly scented. Major Stern

informs us that very little seed of this species was

received. This seed was sown in March, 1915, in ordinary

garden soil which, at Highdown, is particularly full of

lime. The plants raised have proved quite hardy, and

flowered with Major Stern for the first time in 1917,

beginning in July and continuing in flower till August.

They appear to thrive equally well in garden plots and

in pots, calling for a fairly dry situation and good

drainage. The plants fruit very freely, and the seeds

ripen satisfactorily in the open air. The material for

our plate was received from Major Stern in July, 1919,

and in all the specimens so far communicated the

inflorescence has been either strictly umbellate or re-

duced to a single terminal flower. A character which

appears to be variable in L. Farreri is the presence of

tufts of white hairs at the nodes. In the example

figured these were very marked, but in other specimens

subsequently received the leaves and stems are quite

glabrous, so that in this respect L. arreri shares a

peculiarity which, as Professor Bayley Balfour has pointed

out, is well seen in the Nomocharis group, where hairs

may be present on or absent from the nodes in the same

species. There would also seem to be some degree of

variation in the size and shape of the capsules, some of

those received being larger and narrower than that now |

figured and described.

Description.—Herb with an undulately creeping horizontal rootstock about

zy in. thick, with white naked internodes up to 3 in. long, bulbiferous at the

nodes ; young bulbs wide ovoid, acute, over 4 in. long and nearly as thick,

loosely or closely clothed with a few broad thick scales. Stem erect, 2}-2? ft.

high, firm, green, below marked with longitudinal lines of bullate cells, some-

times floccose with white hairs in the axils of the leaves and bracts, sometimes

quite glabrous. Leaves many, scattered throughout the whole length of the

stem, linear-oblanceolate, acute, gradually narrowed to the base, 34 in. long,

over 1 in. wide, with 3-5 main-veins, glabrous on both surfaces and with a

marginal line of bullate cells. Flowers terminal, solitary or aggregated in a

loose 6-flowered umbel, very fragrant; bracts (floral leaves) verticillate, narrow

elliptic-oblanceolate, acute, gradually narrowed to the base, about 1 in. long,

over } in. wide, glabrous; pedicels 3-6 in. long, sometimes white-floccose,

sometimes glabrous at the point of origin of the solitary bracteole which is

attached near the middle of the pedicel and resembles the bracts save for being

smaller and narrower. Perianth-segments revolute, lanceolate, the outer acute,

the inner obtuse, over 2 in. long, nearly } in. wide, white with dark purple

blotches in the lower half, forming at the base a green tube less than } in.

long, finely pilose at the tip and with a nectarial groove provided with two

papillose lines near the base on the upper surface, elsewhere glabrous. Stamens

rather shorter than the pistil; filaments subulate, flattened near the base, about

13 in. long, curving outwards, glabrous; anthers about } in. long, tawny.

The Chinese Salvia described by the late Mr. Franchet

as S. brevilabra was first collected near Ta-chien-lu in

Western Szechuan by Pere Soulié and was sent by him

in 1890-91 to the Paris Museum. We have not had

access to the original type with which Mr. Dunn has

identified, from its description, the plant now figured,

which was met with in the original locality some fourteen

years later by Mr. E. H. Wilson, and was raised from

Aprit-JUNE, 1920,

Wilson’s seeds by Messrs. James Veitch and Sons in their

nursery at Coombe Wood, where it flowered for the first

time in 1905, and was then regarded by Mr. Duthie as

an undescribed species which he named S. brevilabra

owing to his having identified it with a specimen in the

Kew herbarium issued as Soulie, n. 97. This latter

plant has, however, been described by the late Mr.

Leveillé as S. Blinii, and although Dunn has reduced

S. Blinii to S. brevilabra, it is not altogether certain that

Leveillé’s plant is identical with that of Wilson. The

plant which Leveillé had before him differs from the

one now figured in having less coarsely toothed leaves,

densely covered on the undersurface with a rather short

grey pubescence. These features characterise specimens

obtained by Mr. Pratt and issued as Pratt, n. 214, which

are included in S. brevilabra by Dunn. There are thus

certainly two readily distinguishable, if closely allied

forms of Salvia to be found growing at elevations of

10-12,000 feet in the neighbourhood of Ta-chien-lu, and

under the circumstances it seems desirable to regard

them as specifically distinct. Both species are equally

closely allied to the Kashmir species, S. hians, Royle,

figured at t. 6517 of this work, which differs mainly from

S. brevilabra in having much larger corollas with longer

lips, and in having leaves which are usually more regularly

and less coarsely toothed. Plants of S. brevilabra, received

from Messrs. Veitch under the name S. Souliei, have been

in cultivation at Kew for the past twelve years. At

Kew it has proved a hardy perennial, flowering about

midsummer and ripening its seeds. The material for

our plate has been supplied by Mr. H. J. Elwes, in

whose garden at Colesborne, Cheltenham, it grows equally

satisfactorily and has proved equally hardy.

Description.—Herb, perennial; stems erect, about 2 ft. high, rather stout,

sparingly hairy. Leaves of the crown and on the lower portion of the stem

long stalked, the uppermost leaves more shortly petioled, all ovate or narrow

ovate, acute, cordate or hastate at the base, irregularly coarsely crenate or

twice crenate, sometimes slightly lobed near the base, up to 4} in. long,

2-3 in. across at the base, green on both surfaces and beneath with a few rigid

short hairs especially on the nerves; petiole of lower leaves over 5 in. long, of

upper leaves t-1 in. long. Inflorescence over 5 in. long, branched at the

1 in. long, distinctly veined, densely clothed with short, usually glandular

hairs with a few longer intermixed; upper lip semi-orbicular, about 2 in. long,

1 in. wide at the base, minutely 3-dentate ; lower lip about 4 in. long, 2-lobed,

the lobes ovate, shortly acuminate, } in. long. Corolla about 1 in. long,

The Gooseberry now figured, for the material of which

we are indebted to the Rev. W. E. Blathwayt, Dyrham

Rectory, Chippenham, is one that has long been known

in cultivation in this country. According to Loudon,

Aprit-JUNE, 1920.

it was introduced into the garden of the Royal Horti-

cultural Society about 1826 and its first discovery

was made by Mr. David Douglas, somewhere in North-

west America, probably in Oregon or in Washington,

though the precise locality in which it was originally

gathered can no longer be traced with certainty. There

are two specimens of Aibes niveum in the herbarium

at Kew which are attributed to Douglas. One of these

is written up as “Hort. Soc. Ribes like irriguum,”

and is noted as “drawn for Bot. Reg.,” so that it

is probably from a plant raised from seed received

from Douglas. The other bears the legend ‘117 Ribes

triflorum, August 5, 1834. Woods on banks of Columbia.”

But the label is not in the handwriting of Douglas, and

if the date be correct the specimen cannot be connected

with this distinguished collector who was killed in the

Sandwich Islands on 12 June, 1834. It is, however,

possible that A. nivewm may have been one of the

“interesting species of Ailes’? mentioned by Douglas in

his Journal (p. 60), and if so it came from “the moun-

tain on the south side of the river’ —the Columbia—

in the neighbourhood of the Grand Rapids, where he

collected in the early part of September, 1825. The

whole of the remaining references by Douglas to Liles,

and these are numerous in his Journal, appear to be

excluded for various reasons which it is not necessary

to detail. The area occupied by the species extends

throughout Idaho, Oregon, and Washington, where it is

found at altitudes up to 3,000 feet. It was in America

at first confused with R. gracile, Michx, an eastern species

first observed in Tennessee, whence it extends to Illinois,

Kansas, and Texas. J. niveum is interesting as one of

the few Gooseberries in which the flowers are white. It

is also one of the most ornamental. It is easily grown

in any soil of moderate quality and is readily propagated

by cuttings. It has been grown at Kew for at least

three quarters of a century and is perfectly hardy. The

fruits are edible and well-flavoured when cooked.

Description.—Shrub, 10 ft. high, twigs casually armed with usually 1-3

stoutish prickles about 4 in. long, or unarmed; stout suckers rarely sparingly

prickly, Buds oblong, + in. long; outer bud-scales somewhat leathery,

brown, triangular-ovate, rather acute; inner scales scarious, elongated, pale-

contracted short shoots densely clustered; petiole very variable in length,

usually 1-3 in., but at times over 1} in. long; blade rounded in outline with

a truncate or wide-cuneate base, shortly 3-5-lobed, {-1} in. long, 1-1} in. wide,

lobes blunt and coarsely toothed, sparingly pubescent towards the base and

margin, elsewhere glabrous, rarely uniformly softly hairy beneath. Racemes

—T. A. SPRAGUE.

The Berberidaceous genus Podophyllum is the best

known of several herbaceous genera of their natural

family which are represented both in North America and

in Eastern Asia, but are absent from Europe. It differs

from the otherwise nearly related American genera

Diphylleia, Michx, and Jeffersonia, Bart., in the longi-

tudinal in place of valvular dehiscence of the anthers.

The inflorescence of Podophyllum is best understood by

comparison with that of Diphylleia, shown at t. 1666 of

this work, where the flowers are disposed in a long-

peduncled terminal cyme. In Podophyllum pleianthum,

Aprit—JuNE, 1920.

Hance, a Formosan species figured at t. 7098, and in

P. versipelle, Hance, a Chinese species depicted on

t. 8154, both of which have dark red or purple flowers,

the cyme is sessile and resembles an umbel, while in

P. peltatum, Linn., the well-known May Apple of the

Eastern United States, figured at t. 1819, and in its

Himalayan representative P. modi, Wall., of which the

former has always and the latter has normally white

flowers, the inflorescence is reduced to a solitary terminal

flower. In P. Emodi, one variety of which forms the

subject of our plate, we find the only species whose

flowers expand before the leaves. In this case the

solitary flower at first sight conveys the impression of

being subtended by an involucre of sessile laciniate

bracts. This apparent involucre is really composed of

the blades of the two or three cauline leaves which

closely surround the apex of the peduncle by their

cordate bases. At this stage the stalks of the leaves are

appressed to the peduncle of the flower while their blades

are deflexed and not yet fully expanded. Between flower-

ing and fruiting the petioles diverge from the peduncle

and their blades expand to their full dimensions. The

material for our plate we owe to Mrs. Woodward, in

whose garden at Arley Castle, Bewdley, it was raised

from Chinese seed received from Mr. R. Farrer, and

flowered for the first time in May, 1919. There appears

to have been an earlier introduction of P. E’modi, var.

chinense, for in 1914 a plant was presented to Kew by

Mr. H. J. Elwes, Colesborne, Cheltenham, with a note

describing it as a ‘‘ seedling raised from a Podophyllum

of Chinese origin with crimson flowers, sent me by

Leichtlin, without name, some years ago.” This variety

is a native of Kansu and Szechuan, where it occurs at

altitudes of 8,000—10,000 feet, and may be distinguished

from typical P. Hmodi by its much-divided leaves and

constantly rose-coloured flowers. The true P. Emodi,

which occurs in the Himalaya at altitudes of 6,000-

10,000 feet, seems at first sight very different from the

plant figured, for it has tripartite leaves with broad

undivided segments, or with the lateral segments some-

what bilobed. But /. Emodi proper, and its variety

chinense, are connected by the variety Royleanum, Wall.

(P. hecandrum, Royle) which has leaves intermediate in

character. The flowers of true P. Emodi and of its

variety Royleanum are usually white, but may occasionally

be pink. ‘

Description.—Herb, perennial; rootstock stout, horizontal, sending up

annual leaves and erect annual flowering stems; roots many, adventitious,

fleshy, reaching Sin. in length. Stems fleshy, 10-12 in. high, about } in. thick,

clothed at the base with numerous cataphyllary sheaths, 2-3-foliate above with

the internodes at time of flowering 1-2 in. long, bearing a solitary terminal

flower. Leaves of the stem long-stalked, cordate, 3-partite or pedately

5-partite almost to the base ; lobes 3-fid halfway down ; lobules acuminate ; at

flowering-time the erect stalks adpressed to the petiole, and with the partially

expanded deflexed brown-blotched blades surrounding the apex of the peduncle

like a false involucre; nerves and veins sunk above and raised beneath ; lower

surface of leaves white-villous; when in fruit the leaf-blades expanded, about

10 in. across. Sepals fugacious. Petals 6, ascending, obovate, rose-coloured,

with undulate margin, the 8 outer 12 in. long, 1-1} in. wide, the 3 inner similar

but rather smaller. Stamens 6; filaments incurved, about } in. long ; anthers

The Rhododendron now figured was first discovered

by the Abbé David about the year 1870 in woods near

Moupine in Szechuan and was described by the late Mr.

Franchet in 1886 as R. lutescens. It has been met with

again in the same province by Mr. E. H. Wilson on

various occasions when collecting on behalf of Messrs.

J. Veitch and Sons and for the Arnold Arboretum. His

notes speak of it as very common in thickets and in the

Aprit-J UNE, 1920,

margins of woods fully exposed to the sun. In such

situations it is one of the earliest species to open its

flowers ; it varies considerably, Wilson reports, in the

size and texture of its leaves and the number of the,

flowers and stamens. The species was first raised by

Messrs. Veitch in their Coombe Wood nursery from seeds

sent by Wilson from Szechuan in 1904. It was raised

again from seeds, also collected by Wilson, sent to Kew

early in 1909 from the Arnold Arboretum, and the

material for the figure now given has been obtained

from one of the plants of this second introduction. One

of the most distinct of the Chinese lepidote-leaved

Rhododendrons, /. /utescens is readily recognised by the

long-acuminate lanceolate leaves, the axillary yellow

flowers and especially by the stamens, some of which

are quite glabrous towards the base, while others in the

“same flower are densely villous. Notwithstanding its

variability in the wild state, /. lutescens in cultivation

has proved one of the most constant in its characters

and most distinctive in its habit. Save for risk from

late frosts LF. lutescens is hardy at Kew, where it grows

freely in peaty soil or in sandy loam. ate

et Standley in Contrib. U.S. Nat. Herb. vol. xvi. p, 103.—T. A. Spracur.

Linnaeus in 1753 placed both the white water-lily,

figured at t. 819 of this work, and the yellow one figured

at t. 1243, in the genus Nymphaea as N. alba and N. lutea

respectively. Salisbury in 1805 separated the white

from the yellow water lilies, using for the former the

generic name Castalia, and for the latter alone the name

Nymphaea. Sibthorp and Smith in 1808 arrived at the

same conclusion as Salisbury, but retained the name

Nymphaea for the white and used the name Nuphar for

the yellow. Greene in 1887 pointed out for the first

time that the names used by Salisbury have priority.

But while some botanists have adopted the names of

Salisbury, others, and notably Conard, the distinguished

JULY-SEPTEMBER, 1920.

monographer of the water-lilies, have continued to

employ those rendered familar by Smith. We therefore

follow Conard’s usage. The species of Nuphar now

figured as NV. polysepalum is the first of its genus from a

garden standpoint; its flowers are larger than in any

other, and there are nine petaloid sepals as against six

in the other species. The anthers develop a rich plum

colour, and become reflexed, adding to the beauty of the

flower. For the material of N. polysepalum, which is a

native of mountain lakes in Colorado, we are indebted to

Sir F. W. Moore. This material was supplied in 1919

from a plant purchased on the Continent some fourteen

years before under another name. It has proved of slow

growth and hard to establish, the original plant now

having but two good crowns, though it is a vigorous

example. It has to be grown in about two feet of

water with several inches of rich mud. In spring it

moves even earlier than the common JN. lutewm; the

young leaves appear above the water in March; the

flower-buds form in April. The leaves, at first dark

bronze green with a red flush, stand upright and well

above the water for a considerable period before they

eventually bend down to the surface of the pond, while

those leaves that appear later in the season remain

upright even longer than those first formed. ~

Description.—Herb, aquatic, perennial; rootstock creeping, stout. Leaves

mostly floating, long-stalked, ovate-reniform, 8-16 in. long, 6-10 in. wide,

The large and very distinct Plewrothallis here figured

‘ig a native of Costa Rica, where it was discovered near

Cachi by Mr. C. H. Lankester. A living plant was sent

to Kew, together with several other interesting Orchids,

and first flowered in the collection in September, 1917,

when the annexed drawing was made. It belongs to

Lindley’s group Macrophyllae Macemosae, and is most

comparable to the Bolivian P. lamellaris, Lindl., though

the flowers are over twice as large. It is one of the

comparatively few species of a large and very poly-

morphic Tropical American genus, now numbering at

least 500 species, which possesses horticultural merit.

About a dozen of them have been figured in this

work at various times, but none of these are very nearly

allied to the present one. The treatment called for in

Juny-SepreMBeER, 1920.

the case of P. grandis differs from that suitable for most

other species of the genus. It requires warmer conditions

and must be cultivated in an intermediate house. It

thrives well at Kew in fibrous peat and sphagnum moss.

It needs good drainage and the roots must be kept

constantly moist.

The Cotoneaster here figured was raised in the garden

of Mr. G. H. Cave, Rodway Hill House, Mangotsfield ;

it was collected by Mr. G. Forrest in Western China and

distributed under his number 6754. A plant given by

Mr. Cave to Mr. G. H. Wollaston, Flaxley Cottage, Flax

Bourton, flowered in the garden of the latter in 1918

and yielded the fruiting spray shown in our plate, which

was sent to Kew in January, 1919. The flowering spray

figured came from one of Mr. Cave’s plants in July, 1919. |

Mr. Wollaston was of opinion that this plant might be a

form of (. turbinata, Craib, figured at t. 8546 of this

work, only differing from the type in having smooth in

- place of hairy fruits. On the other hand, a spray from

one of Mr. Cave’s plants was certificated at an exhibition

JULY-SEPTEMBER, 1920.

of the Royal Horticultural Society as C. glaucophylla,

Franch. That C. serotina is closely related to both of

the species with which it has been associated is no doubt

true. But when all these are closely examined they are

seen to be quite distinct, C. serotina being readily

separable from C. turbinata by its smooth berries and

from C. glaucophylla by its green leaves. Various other

differences, as Mr. Hutchinson points out, accompany

these salient ones. The name used for this species is

employed because C. serotina agrees with C. turbinata in

flowering as late as August when flowering garden-shrubs

are somewhat scarce. The bright red attractive fruits

persist during the greater part of the winter. C. serotina

appears to share with most of its congeners the features

of hardiness and ease of cultivation; they thrive in any

soil which is not waterlogged, succeeding well even in

the poor sandy soil at Kew, but growing still more

vigorously ina good loam. ‘To secure the best crops of |

flowers and fruit a sunny position should be selected.

Description.—Tree of small size; shoots of the first year silky pubescent,

Daphne tangutica was originally discovered by the

famous Russian traveller, Przewalski, in Kansu, Western

China, in 1873, but was not described and named by

Maximowicz until ten years later. Although quite

distinct in its general aspect from D. retusa, Hemsl.,

figured at t. 8430 of this work, it is undoubtedly very

closely allied to that species. In D. retusa, however, the

leaves are shorter and proportionately broader, the

perulae are more markedly ciliate, and the stigma is

distinctly pubescent. Mr. Rehder, in “ Plantae Wilson-

ianae,” relies on the “ramuli glabri” of D. tangutica to

separate it from D. retusa, but the young shoots of both

are at first covered with small strigose hairs. Judging

from the rather scanty material as yet available, the

Juty-Sepremper, 1920.

umbels of D. tangutica are smaller than those of D. retusa,

the flowers are more densely packed, and the perianth is

more highly coloured. The material from which our

plate was prepared was kindly furnished by Mrs. Wood-

ward of Arley Castle, near Bewdley, with whom it

flowered in April, 1919. It was introduced to this

country in 1914 from Kansu by Mr. Reginald Farrer

under his number 271, and is described in his notes as a

dense, low bush about a foot high and through, found

dotted in open turf on slopes 9,000—10,000 feet above

sea-level, in deep calcareous loam or vegetable mould.

To Kew Mrs. Woodward presented two small plants

which up to the present are thriving well in sandy loam.

But Daphnes are notoriously difficult shrubs to keep

permanently in good health, and it is too soon yet to

say with certainty how D. tangutica will adapt itself to

the climate of the Thames valley. There would appear

to be little to fear in regard to its perfect hardiness at

Bewdley where the original seed was sown in October,

1914, and germinated in March, 1915. The plant raised

stood the frost of 1916-17 perfectly out of doors, and

flowered for the first time in March, 1918. In 1920,

Mrs. Woodward informs us, one plant barely eighteen

inches high bore fifty heads of blossom about an inch

and a half across, while another only a foot high had

ten bunches of flowers. |

This very distinct Coclogyne is a native of the Philip-

pines, and was originally described in 1910, the locality

being given as Mount Pulog, in the Province of Benguet,

in the lower mossy forest, at about 7,000 feet above

sea-level, where it was collected by Mr. E. D. Merrill in

1900. It had previously been collected by Mr. A. Loher

in the same province, as is shown by specimens preserved

at Kew. Some three years after it was described it

appeared in cultivation, having been exhibited by

Messrs. Sander and Sons at the Chelsea Show of the

Royal Horticultural Society in May, 1913. It is allied

to the rare Javan (. cinnamomea, Teijsm. et Binn., but

has a pandurate lip, somewhat narrowed behind, instead

of being broadly ovate, and the area between the entire

keels is dark red-brown, with a band of the same colour

on the side lobes. The rest of the flower is light green.

The plant here figured was received from Messrs. Sander,

- Juty-SePreMBER, 1920-

St. Albans, in 1913, and our drawing was made when it

flowered at Kew in June, 1916. Under cultivation, C.

integerrima thrives well in a tropical house in a compost

of fibrous peat and sphagnum. During its season of

growth it requires a liberal supply of water, but when

the growth has become fully matured all that is necessary

is to supply moisture just sufficient to prevent the

pseudobulbs from shrivelling.

Description.—Herb, epiphytic; pseudobulbs clustered, ovoid-oblong, 2-34

The plate of the Barbery here figured was prepared

from a plant raised from seed collected in Western

Szechuan in November, 1908, at about 5000-6500 feet

above sea-level, by Mr. E. H. Wilson. A share of this

seed had been presented to Kew by Professor C. 8.

Sargent, Arnold Arboretum, and was received under the

‘Wilson’? number 1284. The first of the resulting

plants to flower at Kew did so in April, 1914. In his

original elaboration of the barberies collected by Wilson,

Mr. C. K. Schneider (Plant. Wils. vol. i. p. 360)

identified the plant now figured with the species

described by the late Mr. Franchet as B. levis. Further

study, however, led Schneider to reconsider this deter-

mination, and in a later section of the same work

(vol. iii. p. 437) he made Wilson’s no. 1284 the type of

a distinct species, B. atrocarpa, basing his differentiation

JULY-SEPTEMBER, 1920.

mainly on the “jet-black almost globose fruit’ of

Wilson’s plant, the fruits of the original B. levis being

ovate and blue-black. This particular feature we find,

however, to be far from distinctive, for in B. atrocarpa

the fruits before becoming jet-black are covered with a

blue bloom, while, at least on our plant of B. atrocarpa at

Kew, the fruits rarely approach a globose shape, their

usual form being somewhat narrowly ovoid. Yet there

is little room to doubt that Schneider is fully justified

in regarding B. atrocarpa as specifically distinct from

B. levis. The two species are certainly closely allied,

and are both well marked among their nearest congeners

by the immersed almost invisible secondary nerves of

the leaves. Yet B. atrocarpa is easily distinguished from

_B. levis by its angular grooved branchlets, by its thinner,

longer and proportionately narrower leaf-blades, the

serrations along the margin of which are more remote,

and especially by the smaller number of flowers in a

fascicle. We have not found more than eight flowers

together in B. atrocarpa, and the number is rarely so

great, whereas according to Franchet there are in

B. levis sometimes as many as forty. B. atrocarpa is

one of the most vigorous of evergreen barberies and one

of the most formidably armed, its slender needle-like

spines having a steel-like rigidity. It grows freely, and

although it suffered to some extent in the hard weather

of the early part of 1917, it soon recovered.

Description.—Shrub of erect habit, 5-6 ft. high; branchlets stiff, grey,

glabrous, sulcate, armed with very rigid, three-pronged, pale brown spines

{-1} in. long; internodes 1-23 in. long. Leaves evergreen, in clusters of three

to eight at each node, coriaceaus, glabrous, elliptic-lanceolate, 13-33 in. long,

i-i in. wide, acute, slenderly cuneate at the base, subsessile or with a petiole

up to 4 in. long; margins set with slender, forward-pointing teeth ;); in. long;

dark rather glossy green above, paler beneath, very smooth; nerves scarcely

perceptible. Flowers produced at the nodes in April, in fascicles of 6-12,

yellow, } to } in. in diameter ; pedicels } to } in. long, slender, terete, glabrous.

Sepals oval. Petals bifid at the apex. Fruit ovoid to oval, 3 in. long, at first

covered with a blue bloom, ultimately black and shining, the style adhering at

the summit, ripening in October.

Allium sikkimense belongs to the section Rhiziridiwm in

which the bulb, instead of becoming globose or ovoid,

remains cylindric, and often (as in the present instance)

has its outer coat breaking up with age into parallel

strands of tough fibres. Regel subdivides this section

into those species which have a creeping ‘ rhizome”

and those in which the so-called ‘‘rhizome”’ is perpen-

dicular, but inadvertently places the present species,

which he had not seen, in the former group; its bulbs,

except the slightly curved ones at the outside of a

clump, are cylindric and erect. A native of alpine

Sikkim, A. sikkimense was discovered in August, 1848,

by Sir J. D. Hooker at Lachen between 10,000 and

11,000 feet, and at Tungu at 14,000 feet, and was again

collected in 1911 by Ribu and Rhomoo at Cholamoo, at

an altitude of 16,000 feet. It flowered with Mr. H. J.

Elwes at Colesborne, Cheltenham, in March, 1877, and

again at the same place in June, 1919; in the latter case

from material supplied by Mr. G. H. Cave. It is also

established in the Rock Garden at Kew, where the

plant here figured was raised from seed received in 1917

from the Royal Botanic Garden, Calcutta. At Kew it is

quite hardy and ripens its seeds. Besides A. sikkimense,

two other species of Allium with blue flowers have been

in cultivation. One of these, A. kansuense, Regel (A.

cyaneum, var. brachystemon, Regel) has been figured at

plate 7,290 of this work and is a native of the Chinese

province of Kansu, where it has been found during

recent years at elevations of 9,000 to 10,000 feet by

Mr. E. H. Wilson and Mr. R. Farrer; it has also been

successiully grown by Mr. H. J. Elwes. It much

resembles A. sikkimense, from which it differs in having

all the filaments toothed at the base, a character which,

although inconspicuous, may be of some significance in

connection with pollination. The other species is A.

cyaneum, Regel (Gartenflora, t. 1317, fig. 2), also from

Kansu, which is readily distinguished by its filiform

semiterete leaves and by its stamens being twice as long

as the perianth and haying only their alternate filaments

toothed at the base.

Dxscriprion.—Herb, bulbs tufted, vertical, cylindric, sometimes as much as

2 in. long, the outer sheaths with age fibrous. Leaves 2-3, superposed,

The genus Subia, belonging to the small but distinct

order Sabiaceae, includes ‘some twenty-five to thirty

species, mostly climbing shrubs, fairly widely distributed

in Eastern Asia. Few of these have been introduced to

European gardens, and hitherto no species of the genus

has been figured in this work. The one here described,

S. latifolia, was first discovered by Mr. A. E. Pratt in

the neighbourhood of Ta-chien-lu. Twenty years later

it was encountered again by Mr. Wilson in the same

JuLy-SeEPpTEMBER, 1920,

neighbourhood, growing in thickets at about 8,000 feet

above sea-level. The plants now in cultivation were

raised from seed collected by Wilson, though during the

interval between its discovery and its introduction the

species has been met with at least on two occasions;

specimens from Szechuan were communicated by Mr. A.

Henry in 1890, and others from Western Hupeh were

gathered by Wilson in 1900. For the material for our

figure we are indebted to Miss E. A. Willmott, in whose

garden at Warley Place S. latifolia has been in culti-

vation for the past nine years. Here it has thriven

against a north wail, flowering and ripening its fruits

every season. The original plant, which is now about ten

feet high, was raised from the only seed which germinated

out of a few collected by Wilson and received from the

Arnold Arboretum. At Warley Place this plant has not

been given any special protection, and has proved quite

ardy. Propagation has been effected by cuttings, by

division, and from seed.

Acacia spectabilis well deserves the name suggested for

it by Cunningham on its first discovery in Wellington

Valley, New South Wales, nearly a century ago, for in

spite of the fact that as cultivated under greenhouse -

conditions in this country it develops into a plant of

somewhat straggling habit, it is when in full blossom an

exceedingly beautiful object, the glaucous hue of the

foliage greatly enhancing the effect produced by the

yellow globose flower-heads it produces in such abun-

dance. A native of the subtropical regions of Eastern

Australia from about Lat. 26° 8. in Queensland to about

34° 8. in New South Wales, it was introduced to

JULY-SEPTEMBER, 1920,

European collections shortly after its first discovery, and

has been in cultivation in England ever since. Doubt-

less it has been reintroduced oftener than once; the last

occasion on which this has occurred at Kew was in 1909

when seeds were received from the Sydney Botanic

Garden. One of the plants raised then flowered for the

first time in the Temperate House at Kew in February,

1914, when the drawing from which our plate has been

_prepared was made. It has flowered freely in spring

every year since then. As Mr. Hutchinson points out,

_it is nearly related to two other Australian species of

Acacia, A. polybotrya, Benth., and A. pruinosa, A. Cunn.,

both of which are to be met with in greenhouse

collections.

Description.—Shrub of considerable size; twigs eventually becoming

purplish, at first covered with spreading pubescence, but soon becoming

glabrous. Leaves 2-pinnate, hardly as long as the inflorescence, over 2 in.

long; pinnae 2-5-jugate; glands obscure; leaflets 4-8-jugate, oblong or

Arisaema Fargesii was described by Mr. Buchet from

specimens bearing male flowers only, collected at Hong-

lan-sin, at an altitude of 6,000-7 ,000 feet, in the district

of Tchen-keou-tin, in the province of Szechuan, but he

refers to the same species a plant with female flowers,

which he has seen growing in the collection of Mr.

Maurice de Vilmorin, who had received it from Szechuan.

This plant was larger in all its parts than the male plant

upon which the original description was based, and

agrees with the plant here figured, which was received

at Kew in 1917 from Mr. de Vilmorin and flowered in

May, 1919. The leaves of J. Fargesii resemble those of

A, ringens, Schott, which differs in having a spathe with

even more pronounced auricles but with a shorter apex.

In colour, the spathe is like that of A. speciosum, Mart.,

but in this the spadix is produced into a long filiform

appendix much longer than the spathe. The spathe in

JuLy-Sepremperr, 1920

all the above mentioned species is inarched so as to form

a hood, and the whole inflorescence is sheltered by the

patently spreading leaflets, which are decurved in the

upper part. At Kew this species thrives well, like the

various Himalayan species of the same genus, under

ordinary greenhouse treatment.

Desoription.—Herb, with a depressed globose tuberous corm which produces

@ solitary leaf along with a solitary flower spike. Cataphylls brown, narrowed

upwards, obtuse or acute. Leaf 3-foliolate, glabrous; leaflets spreading,

shortly petiolulate, the central somewhat rounded, cuspidate, 11 in. long;

lateral rather shorter than the central, cuneate at the base on the inner,

rounded on the outer side; petiole half as long again as the lamina, fleshy.

Pedunele erect, fleshy, 6 in. high. Spathe purple, marked with whitish lines ;

tube nearly cylindric, 3 in. long, ¢ in. across ; limb oblong-deltoid, long

acuminate, galeate, the throat very distinctly auricled, 5} in. long, 2} in. wide.

Spadia 1-sexual, over 4 in, long ; appendix included in the spathe, 3 in. long,

contracted above the flower-bearing portion, thence narrowly lanceolate

upwards to the blunt tip, brown ; the flowers, only females seen, congested at

the base of the spadix. Ovary angular by compression, somewhat rounded at

the tip ; style very short and thick ; stigma penicillate ; ovules few.

The Rosaceous genus Stranvaesia includes only five or

six species, closely related to each other and separable

_ only by rather slight characters. The distribution of the

various forms is interesting, for the genus extends in

India from Kumaon to the Khasia Hills and Burma, and

extends thence into central and western China, while a

solitary species occurs at high altitudes on Mount Kina-

balu in Borneo. So far no representative of the genus

has been met with in the Malay Peninsula. The species

here described as 8S. salicifolia is very nearly related to

S. undulata, Decne, from China, figured at t. 8418 of this

work. From S. undulata our plant differs in its narrower

willow-like leaves, its quickly deciduous stipules and

bracts, and especially in its fruits which are red in place

of orange. From the horticultural standpoint at all

events the two plants are abundantly distinct. Our

plate has been prepared from an example which has

JULY-SEPTEMBER, 1920,

proved quite hardy at Kew, where it thrives well in

loamy soil. It was received as a small plant from the

Arnold Arboretum in 1910, and as cultivated alongside

S. undulata has become a taller plant of much stronger

growth, less compact in habit. It flowers freely and

perfects its fruit in sufficient quantity to render it a

singularly handsome autumn plant. It may be increased

by seeds,

CURTIS’S BOTANICAL MAGAZINE.

In consequence of the increased and

still increasing cost of producing Curtis's

Botanical Magazine, the Publishers propose to

terminate the fourth series with the present

issue, Vol. 16 (1920), or Vol. 146 of the

complete work.

Before committing themselves further

they desire to ascertain, in some way, whether

the work fulfils a sufficiently useful botanical

and horticultural purpose to justify its con-

tinuance, and, if so, under what conditions

it may be possible to do so.

THE FLOWERING PLANTS OF

SOUTH AFRICA.

A MAGAZINE CONTAINING HAND-COLOURED FIGURES WITH DESCRIPTIONS

OF THE FLOWERING PLANTS INDIGENOUS TO SOUTH AFRICA.

EDITED BY

I. B. POLE EVANS, M.A., D.Sc, F.LS.,

Chief, Division of Botany and Plant Pathology, Department of Agriculture, Pretoria ;

and Director of the Botanical Survey of the Union of South Africa.

EXTRACTS FROM THE EDITOR’S PREFACE.

Ir is proposed to issue this publication as an illustrated serial, much on

the same lines as the well-known Curtis’s Botanical Magazine, and for

imitating which no apology need be tendered.

Should the publication be the means of stimulating further. interest

in the study and cultivation of our indigenous plants amongst the rising

generation, the desire and object of its promoters will be achieved.

Living plants suitable for illustration, plants of economic value, or

plants of general interest, will always be gladly received and welcomed

by the Editor.

The illustrations are from drawings by Miss K. A. Lansdell, while

the descriptions have been prepared by Dr. E. Percy Phillips, Botanist

in charge of the National Herbarium.

_ The illustration on our cover represents a glimpse of the magnificent

Union Buildings at Pretoria, under whose shadow this work is being

prepared, and on whose site the plants here figured are grown.

It has been the Editor’s privilege and good fortune to see a com-

paratively bare kopje converted in the course of a few years into the site

of a grand and stately building surrounded with many of the country’s

most beautiful and interesting herbs and shrubs.

For the contents of the first two numbers, see over.

The work will be issued every three months, commencing on

November Ist, 1920, each part containing ten coloured plates, price 15s.,

annual subscription 60s. (postage 2s.).

Verbascum Blattaria, well known in gardens in this

country, is also to be found, as a somewhat rare alien, in

waste places from Lincolnshire southwards; in some of

our southern counties it may perhaps be truly native.

As a wild species it is widely spread in central and

southern Europe, in northern Africa and in the Orient.

Though it has long been in cultivation, the plant as

grown in gardens seems always to have yellow corollas,

though forms with the flower more or less white have

occasionally been recorded in the wild state. The form

OcropER—-DEcEMBER, 1920.

here figured as var. grandiflora, in which the flowers are

white and the corollas are much larger than in typical

V. Blattaria, Linn., seems to be of doubtful origin.

For the seeds from which the subject of our plate was

raised Kew is indebted to the Director of the John

Innes Horticultual Institution, Merton, and the original

parent plant it is understood came from Lincolnshire,

where it was found growing in a corn-field. At Kew it

calls for no special treatment. The seeds were sown in

1918 and the plants flowered in 1919, those under green-

house conditions in May, those in a border outside

somewhat later, in both cases ripening seeds freely.

Notwithstanding the striking appearance of this new

variety, it differs from typical V. Blattaria mainly in the

extreme luxuriance of all its parts.

Description.—Herb, biennial ; stem 14-2 ft. high, with 2-3 branches towards

the top, glabrous downwards, slightly and finely glandular high up. Leaves

The distinct and striking Rhododendron here figured is

a native of Western China and appears to be confined to

the province of Szechuan where it was first met with in

1885 by the Abbé David, near Moupine, at an elevation

of about 9,000 feet above the sea. The plant from

which the material for our plate was cut was obtained

from the nursery of Messrs. J. Veitch and Sons at Coombe

Wood in 1908. It had been raised there from seeds

collected in Szechuan by Mr. E. H. Wilson. This plant

is now four or five feet in height and forms a well-

furnished, compact and handsome bush which usually

flowers at Kew in March or April. The warmth of the

OcroBER—DECEMBER, 1920,

early weeks of 1920 however brought the blossoms of

ft. strigillosum to perfection by the middle of February,

when our drawing was prepared. This habit of early

flowering renders the blossoms liable to injury by spring

frost, and the young growths suffer from the same cause,

It appears to succeed best in thin woodland, where it is

shaded from the sun in the early and middle hours of

the day. According to Mr. Millais the flowers vary in

colour from rich red and crimson to white. The five

black pouches at the base of the corolla are usually full

of nectar. Even when out of flower &. strigillosum is

readily distinguishable by its very bristly young shoots.

Descrirtion.— Shrub, 4-5 ft., or at times a tree up to 20 ft. high ; twigs

densely setose towards the tip, with long rigid blackish hairs. Leaves

narrowly oblong-Janceolate, acutely acuminate, slightly narrowed and shortly

cordate at the base, 3-6 in. long, 3-1} in. wide, firmly coriaceous: to nearly

papery, reticulated above, beset underneath with crisped hairs; midrib sunk

above and hispid towards the leaf-base, much raised beneath and tomentose ;

lateral nerves about 12-18 along each side the midrib, from which they diverge

at a wide angle, becoming obsolete towards the margin; petiole }—3 in. long,

setose-hispid and tomentose. Inflorescence terminal, about 10-flowered ;

bracts densely wooll

y outside ; pedicels about 4 in. long, densely setose with

black gland-tipped hairs. Calyx short, setose outside. Corolla red, with

5 black basal blotches inside; tube narrow campanulate, glabrous outside,

1} in. long, 1 in. wide at the throat; lobes 5, rounded, emarginate.

Stamens 10, exserted; filaments pale purple, glabrous, about 1} in. long;

anthers nearly black, 1 in. long. Ovary 5-celled, densely strigillose; style

pale purple, rather longer than the stamens, glabrous, tipped by the lobulate

stigma, Capsule about 2 in. long, densely setose with rigid purple hairs.

The interesting /’ritillaria here figured is a charac-

teristically Orient species with its headquarters in

Thrace. It is reported to be plentiful near Constanti-

nople and on the northern shores of the Bosphorus and

the Sea of Marmora. Thence it extends southward into

Bithynia and Anatolia, northward into Bulgaria and

westward into Macedonia. It is usually found in woody

places on hilly ground or among the foot-hills. The

material for our plate was supplied by Mr. Hamilton

Blanchard from his garden at Cotswold, Parkstone, the

plant figured having been raised from a bulb sent from

OcropeR—DECEMBER, 1920.

Macedonia by Mr. Douglas Blanchard. To the latter we

are indebted for the information that in Macedonia, as in

Thrace, F’. pontica is generally distributed and prefers

shade. Most of the bulbs sent by him to his brother

came from a nullah running into Gumus Dere, near

Kopriva, and the Sargest, from the slopes of Black Peak

near Paprat. Here J. pontica flourishes under the

shelter of bushes at about 3,000 feet above the sea.

Mr. H. Blanchard’s experience with the plant extends

over three seasons. The bulbs first received were all

small and had been lifted very early; grown in pots in

full sun the plants died without flowering. The second

consignment, also lifted early, included some larger

bulbs. The plants started growth too soon and were

injured by spring frosts, some being cut to the ground. »

Grown in sandy soil with partial shade and an eastern

exposure, some of them flowered when six inches high.

The final consignment, of mature bulbs, grown on the

north side of a hich wall, produced plants which flowered

when a foot high, formed capsules and matured seeds.

In a soil suitable for other species of /’ritillaria* and if

given sufficient shade, F” pontica is likely to prove hardy.

The species belongs to the group Monocodon in which the

bulbs are tunicated, the styles are tricuspidate and the

nectaries are uniform. The colour of perianth appears

to vary, especia'ly in cultivated plants, between dark

green upwards tinged with purple and pale yellowish-

green, but the absence of tesselation is constant.

Description.—Herb, Stem erect up to 1} ft. high, usually 1-flowered, leafy

above, naked in the lower half. Leaves glabrous, green, 2-8 in. long, 3-2 in.

wide, the lower opposite or alternate, lanceolate or oblong-lanceolate, blunt, the

The Myrtaceous genus’ Melaleuca is a member of

the tribe Leptospermeae, which includes many of the

Australian plants that a century ago received much

attention in English gardens and conservatories. _ The

most familiar genera in the group are Lucalyptus, which

includes the Australian Blue Gum, and whereof the

species best known in our collections is the Tasmanian

E. Gunnii, Hook. f., a mountain form of which is figured

at t. 7808 of this work; Leptospermum itself, whereof

L. scoparium, Forst., the Manukaof New Zealand, is most

generally grown; and Callistemon, whereof the Australian

species C. pinifolius, figured at t. 3989, is to be met with

in English gardens. It is to the last named of these

genera that Melaleuca, of which over a hundred species

are known, is most nearly allied. Several of these have

already been described in this Magazine, and will be

found represented on tt. 1058, 1868, 1935, 2268, 3210,

4471, 6131, 7529, 7941. The species now described,

M. Radula, which has not been figured hitherto,

OcToRER—DECEMBER, 1920,

possesses the added interest of having been unknown

in European gardens even during the period when

growers, were less unwilling than they are to-day to take

the trouble called for in the cultivation of hard-wooded

Australian shrubs. The material for our plate has been

obtained from a plant raised from seed received from

Australia in 1906 as that of Eucalyptus eugenioides, which

flowered at Kew in October, 1915. This name being.

obviously erroneous, the drawing then prepared was

submitted to Mr. J. H. Maiden, Director of the Sydney

Botanic Garden, to whom we are indebted for its identi-

fication. A small virgate shrub, with rather narrow

Spreading opposite leaves and large lilac purple flowers

borne in axillary pairs, If, Radula flowers freely under

greenhouse treatment in late autumn and is a welcome

addition to conservatory collections. It is a native of

Western Australia, where it was first collected in the

Swan River district by Mr. James Drummond, and was

first described from his specimens by Professor Lindley.

Its natural range appears to be rather limited, though it

18 not uncommon within its special area, for it has since

then been collected by Preiss near the Cunning River,

by Oldfield at Champion Bay and on the Murchison

River, and by more recent travellers in neighbouring

districts. Its nearest ally in the genus is M. linearifolia,

Smith, another species from Western Australia, from

which J. ftadula is readily distinguished by the involute

leaf-margins, and by the larger flowers which are never,

asin M. linearifolia, arranged in a terminal panicle.

The Aniphojia which forms the subject of our plate

was originally discovered in October, 1916, by Mr. J. D.-

Snowden of the Department of Agriculture, Uganda,

growing among short grass and in small scrub on the

slopes of Mount Elgon at about 8,000 to 10,000 feet

above sea level. In 1918 seeds collected in the same

locality were forwarded to Kew by Mr. R. A. Dummer.

From these, plants were successfully raised, some of which

flowered in the open in September, 1919, The plant

collected by Snowden, on which the original description

of our species was based, was considerably smaller than

the plants raised from the seed supplied by Dummer,

but did not differ in other characters. Fortunately while

these were in flower Mr. Snowden, when visiting Kew

while on furlough, had an opportunity of seeing them, and

recognised in them, without hesitation, the species he

had collected on Mount Elgon. In his original specimen

the leaves are only a foot long, and the inflorescence is two

feet high, whereas the plants raised at Kew reach a height

of five feet, with leaves two feet long. Such dimensions

Mr. Snowden assures us are often. attained by the wild

OcToBER—DrcempeEr, 1920.

plants he has seen. Mr. A. Berger has relied upon the

width of the leaf as a diagnostic character in separating

the species of Kniphojia, but while this feature may be

reliable in the case of plants growing under identical

conditions, it may prove less satisfactory when dealing

with specimens from different localities. Another rather

variable character is the colour of the flowers. These are

sometimes uniformly red, sometimes uniformly yellow.

In certain cases, however, the flowers though red in bud

become yellow when mature. The stamens are included,

but the style in the fully developed flower is shortly

exserted. The nearest ally of K. Snowdeni is K. longi-

styla, Baker, a Nyasaland species which has a cylindric

glabrous perianth, and is thus easily distinguished from

the one now figured, in which the perianth is densely

pubescent and is constricted above the ovary as in the

Genus Gasteria.

Description.—Herb, with tufted linear leaves, 1} in. wide, glabrous, about

15-nerved, with entire hyaline margin. Peduncle 5 ft. high, cylindric; spike

1 ft. long; bracts ovate, long acuminate, $+ in. long. Pertanth 1} in. long,

slightly curved, constricted above the ovary, pubescent outside, strongly

ribbed, red or yellow; lobes rounded, blunt, about 1, in. long and wide.

This South African Heath is rather widely spread in the

Coast Region of Cape Colony. It has been frequently

reported from the Cape, Stellenbosch, Paarl, Tulbagh

and Caledon Divisions, is not uncommon in George and

Knysna, and has been found as far east as Humansdorp.

With so wide a range it is hardly surprising that there

should be a considerable degree of variation in some of

its characters, more especially the length and width of

the corolla and the size, shape and margins of the sepals,

This variability is reflected in the synonomy which

OcToBER-DecemBER, 1920,

indicates a tendency during the period when the

cultivation of Cape Heaths was popular to place undue

reliance on characters, derived from the corolla, that

South African field-botanists have found to be unstable.

The late Mr. Bolus, one of the most distinguished of these,

has recognised three segregates from the type, to which

our plant appears to belong; in so doing, however, he

has relied on differences in the calyx alone, and has not

suggested that his segregates are more than varieties.

For the reintroduction of this species to Kew we are

indebted to the Director of the National Botanic Garden

at Kirstenbosch, from whom seeds were received in

February, 1915. One of the plants raised from these

seeds flowered ina greenhouse at Kew in June, 1919. A

plant of sturdy habit and robust growth, ZL. sessiliflora

is striking on account of its semi-transparent flowers.

A member of the subgenus Syringodea, it has been placed

in the Mammosae group of the section Pleurocallis and is

allied, though not very closely, to EZ. guva, Wendl., from

which it is easily distinguished by its sessile flowers

and different corolla. It is readily separated from E.

Broadleyana, Andr., and E. Bowieana, Lodd., by its dense

close spike, from E. mammosa, Linn., by the corolla

being terete at the base, and from E. filipendula, Benth.,

by the ovary being sessile.

This Syringa was discovered by Prof. Henry at Fang

in the Province of Hupeh, Central China, at 8,000 to

9,000 feet, but his material, collected in 1889, was not

described till 1910, when specimens collected by Mr.

EK. H. Wilson in the same province between 1901 and

1910 had been received. Mr. Wilson sent seeds to the

Arnold Arboretum and was thus the means of in-

troducing the species into cultivation. The plants at

Kew were raised from seeds received from the Office of

Woods, Forests and Land Revenues:in 1911, and are now

about five feet high. While closely resembling in foliage

and flowers several other cultivated species, it is very

distinct in its pendulous inflorescence, a character well

shown in Mr. Wilson’s excellent photograph. Though

probably most nearly allied to S. Sargentiana, C. K.

Schneider, our plant has much in common with S. villosa,

Vahl, which, however, besides having an erect and much

broader inflorescence, may be distinguished by its fruits,

which are. straight and wartless. Nine other species of

Syringa have been figured in this Magazine including the

Common Lilac, S. vulgaris, Linn., in 1792 (t. 183), and

S. persica, Linn., in 1800 (t. 486). The former, the

* Lylac Mathioli’ and ‘Blew Pipe’ of the old herbalists, .

is included in the catalogue of Gerard’s garden published

in 1596. S. persica was in Tradescant’s garden prior to

1640; according to Parkinson’s Theatrum. In 1876,

when the part of Bentham and Hooker’s ‘Genera

Plantarum’ containing the Oleaceae appeared, only 6

species of the genus Syringa were known. Now there are

upwards of 30, mostly natives of China, many of which

have been discovered and introduced into European and

American gardens since the beginning of the present

century. 4S. reflexa thrives in rich loamy soil, and can be

increased by cuttings of leafy shoots put in gentle heat

towards the end of July.

Description.—Shrub, up to 15 ft. high; twigs faintly 4-angled, copiously

lenticellate, green and sparingly shortly pubescent in their first year, grey and

glabrous by the second season. Leaves petioled, elliptic-oblong, obovate or

sometimes wide lanceolate, acute or shortly acuminate, base more or less

cuneate or occasionally slightly rounded, entire or faintly repand, 23-6 in.

long, 14-3 in.-wide, distinctly veined, sparingly pilose especially on the main

This handsome /Phlomis was first discovered in

Kashmir by Victor Jacquemont during his travels in

Ocroper-DecemBER, 1920.

Northern India in 1828-32.. It has since been collected

by several travellers in the same region, growing at

elevations of from 3,000 to 8,000 ft., in the Kurrum

Valley, Afghanistan, by Dr. Aitchison; and at Ziarat,

Baluchistan, at 8,500 ft., by the late Mr. J. H. Lace. It

does not appear to have been introduced into cultivation

in this country till Mr. H. J. Elwes obtained seeds

collected in Kashmir by Mr Radcliffe of the Forest

Department, from which he raised some plants in his

garden at Colesborne, Gloucestershire; from these he

sent flowering material to Kew in September, 1916, and

again in August, 1919. Attaining as it does a height of

about six feet, with basal leaves up to a foot long and

dense whorls of rather large rose-purple flowers, it forms

a striking object in the herbaceous border. It is easily

cultivated, Mr. Elwes informs us, in any soil and is quite

hardy in the open. The genus Pélomis now comprises

over eighty species, about twenty of which are or have

been in cultivation. The well-known /. fruticosa, L., a

native of South-eastern Europe, is occasionally found

naturalised in England. In the Flora of British India

it is suggested that P. oreophila, Kar. and Kir., from

Alatau, is probably a small state of P. spectabilis. The

two species are manifestly quite distinct. The plant

now figured is assigned by Bentham to the first

(Luphlomis) of the two sections into which the species of

Phlomis are grouped. The flowers are, however, much

‘more correctly described in the definition of the sec-

tion Phlomidopsis, which includes P. tuberosa and

P. macrophylla, species obviously closely allied to P.

spectabilis,

Rhododendron Sargentianum is a member of a group of

some fifteen species of dwarf shrubby Rhododendrons

with aromatic leaves, clustered capitulate inflorescences,

tubular corollas that are usually villous within, short

included stamens and very short capsules which are

more or less invested by the hardened calyx. The

species was discovered by Mr. E. H. Wilson in 1903 near

Washan in Western Szechuan, when collecting on behalf

of Messrs. J. Veitch and Sons, and was again met with

by him, growing on exposed rocks near Moupine in the

same province both in 1908 and in 1910. ‘The central

species of the group to which it belongs is A&,

OctoBeR-DeEcEMBER,. 1920,

cephalanthum, Franch., also from south-western China.

As is shown in our illustration, at fig. 8, the plant from

which our figure was prepared has some of its filaments

devoid of anthers; that this reduction may have been

the result of cultivation is probable ; the presence of the

tendency may nevertheless have some bearing on the

taxonomic status of the group to which R. Sargentianum

belongs. Being dwarf, compact and slow of growth,

this species is admirably suited for cultivation in the

Rock Garden, where it should be provided with a mixture

of sandy loam and peat. It will probably thrive best in

a nook shaded from the mid-day sun. Failing seed, it

can be propagated by cuttings taken in July and placed

in very sandy soil under a bell-glass in gentle heat.

The plant now figured was presented to Kew by Mr.

F. R. 8. Balfour of Dawyck, Peebleshire, in March, 1914.

It flowers in May.

Description.— Undershrub, reaching a height of 2 ft., much branched, the

twigs erect or ascending, when young very short and loosely covered with

soft scales, when older beset with persistent bud-scales, Leaves aromatic,

wide elliptic, mucronate, sometimes slightly emarginate, base wide euneate

This distinct and striking Mesembryanthemwn was

presented to Kew in 1910 along with various other

_ succulent plants by Mr. G. H. Simpson Hayward, Icomb

Place, Stoke-on-the-Wold. It has thriven satisfactorily

under the treatment given to other species of the genus

in a warm greenhouse, where it flowered in November,

1918, when our figure was prepared. Beyond the fact

that it is South African nothing is known of its history,

for there is no record of the district in which it was

collected, and no very near affinity can be found or

claimed for this species, which is new alike to horti-

culture and to science. In most respects M. dichroum

accords with the members of the section Calamiformia,

though it is at once distinguishable from all of these

by having distinctly triquetrous in place of subterete

leaves and in having petals with bright pink apices.

It appears on the whole more satisfactory to include our

plant provisionally among the Calamiformia, though as a

somewhat anomalous member of the section, than to

regard it as the type of a distinct section, though this

OcroBER—DECEMBER, 1920. ;

may eventually be found to be necessary. M. dichroum

is a pleasing addition to the succulents in cultivation

owing to the colouring of the petals. It is a dwarf plant

with very glaucous linear-oblong leaves and with shortly

pedicelled flowers; the petals, otherwise white, are

strongly suffused with pink towards their tips.

Description.—Herb, with short simple or sparingly branched suberect stems,

3-33 in. high. Leaves 4-5, spreading, linear-oblong, acute, 3-quetrous, thick,

concave above, bluntly keeled beneath, glaucous, closely and finely toothed.

Flowers nearly sessile, 3-1} in. across, white flushed with rose-pink. Calyx

wide campanulate ; lobes deltoid ovate, acute. Petals very many, spreading,

about ? in. long, white below, rose-pink at the tips. Stamens many, erect,

oblong, obtuse, yellow. Stigmas 6, subclavate, short.

The history of this handsome Odontoglossum is of

unusual interest. The late Professor Reichenbach in

1876 described as 0. Humeanum a plant imported from

Mexico which had then flowered in the collection of Mr.

W. Burnley Hume. The characters were such as to lead

Reichenbach to think it a natural hybrid; the parents

suggested were QO. Rossii and O. ccrdatum, two Mexican ~

species described by Professor Lindley. Three years

later another plant flowered with Messrs. J. Veitch and

Sons. This Reichenbach described as O. aspersum, again,

however, in the belief that it was a hybrid, but with the

Ocroper-DeceMseEr, 1920.

suggestion that while O. [ossii is one parent, the other

might be O. maculatum, a Mexican species named by La

Llave. Subsequent importations of 0. fossii have in-

cluded a certain proportion of individuals that on flowering

have suggested some admixture with O. maculatum, which

is known to grow in the same district as O. Rossii. It

seems clear now, however, that Mr. Hume’s plant was

not the first instance of the flowering in this country of

a natural hybrid between (0. Rossii and another species. —

The plant figured as 0. cordatum by Paxton, which

flowered with Mr. 8. Rucker at Wandsworth in 1847, is

manifestly the same as the subject of our plate. This

plant was afterwards transferred by Veitch to 0.

maculatum, the fact that it is identical with O. aspersum

being overlooked. The confusion of these two species

themselves, for the plant figured as O. maculatum at

t. 4878 is really O. cordatum, may have contributed to the

uncertainty as to the parentage of this hybrid. That

uncertainty has been increased by the circumstance that

the whereabouts of Mr. Hume’s plant, if it still survives,

is unknown, and by the fact that the material on which

Reichenbach based his O. Humeanum has lain so long

inaccessible in his herbarium. In any event it was

essential, before it could be definitely decided whether

either, and if so which of the suggestions made by

Reichenbach be correct, that advantage be taken of

the first suitable opportunity of effecting the necessary

_ artificial cross-fertilisation. By a fortunate accident

Mr. Rolfe was able to enlist the interest of Mr. F. H.

Moore, of the Royal Infirmary, Liverpool, who in May,

1899, had O. Rossii and O. maculatum in flower together

in his collection. The two species were crossed by Mr.

Moore and some hybrid seedlings were raised, one of

which has happily survived and has been the subject of

careful observation. At six years of age this plant, which

had not yet flowered, passed into the care of Mr. W. H.

Young, then in charge of the collection at Clare Lawn.

A year later, on the death of Sir F. Wigan, it came to

Kew, where it has since been grown with other Odonto-

glossums, planted in a smali basket suspended near the

roof-glass of a cool orchid house. In 1918, when nine-

teen years old, the plant flowered for the first time,

producing the inflorescence of four blooms here figured:

which agree exactly with those of the wild presumed

natural hybrid collected in Mexico.

Descriprion.—Herb, epiphytic ; pseudobulbs clustered, ovoid-elliptic, some-

what flattened, 13-2} in. long, clothed at the base with ovate-lanceolate

sheaths, 2-foliate at the apex. Leaves lanceolate-oblong, acute, conduplicate

and narrowed at the base, 3-8 in. long, 1-1} in. wide. Peduncele erect or

curved, 6-8 in. long, 8-4-flowered. Flowers showy, pale yellow with the sepals

and the bases of the petals blotched with brown; bracts ovate-lanceolate,

acute, #-1 in. long; pedicels 1}-2 in. long. Sepals oblong-lanceolate, acu-

minate, 13-1} in. long. Petals elliptic, acute, somewhat undulate, 1} in.
