In 1860Reichenbach 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 

•Ianuary-March, 1920, 



in a 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 1S60. 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.

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. 
II. 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„, 

January-March, 1920. 



where it occurs as a small shrub, two feet high, in open 
stony places. Seed received from Mr. Forrest was BOwn 
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 1!>17. 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 nenus, there is much 
difference between the truss of a well-grown plant such 
as the one figured, and that of a badly grown one.

The North American Winterberry, sometimes also 
known in north-eastern America as the Black Alder, has 
Ions been a favourite in English gardens, to which, 
according to Aiton, it was introduced for the first time 
in 173(1 It is found wild over a wide area on the eastern 
side of North America, ranging from Nova Scotia and 

January-March, 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. Ilex 
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. Linnaeus, 
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 Ilex, 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 Aquifolium 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- 
folium. The nearest ally of /. verticillata is /. la* vigata, 
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, /. 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. /. verticillata can 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 bona of Bagshot in October, 1917, when it happened to 
be id bearing and in unusual profusion. The male and 
lemale 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 
-crotessor 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. 



Description. — Shrub 8-20 ft. high, usually dioecious ; young shoots glabrous 
in the typical form, dark brown, sparingly beset with pale lentieels. Leaves 
deciduous, oval, narrowly obovafe, or oblanceolate, acute or acuminate, base 
cuneate, margin finely and often unevenly serrate or 2-serrate, 1 i —3 ^ in. long, 
i-l£ in. wide, glabrous or slightly pubescent above, always pubescent beneath 
especially near the midrib, strongly reticulate ; petiole J-j 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, y\- 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. Fruit a scarlet 
globose or ovoid drupe, usually solitary, occasionally in pairs cr threes in each 
axil, i 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

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 C. florida, Linn., 
figured at t. 8315 of this work, and C. Nuttallii, 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. C. Kousa flowers 
in May and thrives very well 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.

The handsome Chinese Rhododendron here described 
was first met with by the Abbe' Soulie in 1893 in the forests 
of Tongolo and in the vicinity of T-a-chien-lu in Western 
Szechuan and was characterised two years later, under 
the name Rhododendron 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-March, 1920. 



name R. vernicosum now employed. A decade later seeds 
of R. 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 byKevv 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 Soulie's species is a 
variety, var. lucidum, of another Chinese Rhododendron 
described by Lindley in 1859 as R. Fortunei, T. Moore. 
The flowers of the true R. Fortunei 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 R. Fortunei. The smaller leaves, 
unequally rounded at the base, and the shape of the 
corolla-tube are also distinguishing features. Since the 
collection of R. 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 
Irom the rays of the mid-day sun.

This attractive heath, a new species of the small 
section Eurystegia 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 

Jamah v .March, 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 flowered 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 Erica already 
described, now nearly 500, E. Haroldiana (named after its 
discoverer, who is also commemorated in the genus hy E. 
Pearsoniana, L. Bolus) is clearly most nearly allied to E. 
noUUs, 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. E. Monsoniana, Linn., of which the 
variety exserta, Klotzsch, is figured at t. 1915 of this 
Magazine as E. Monsoniae t ia 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. E. 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 E. verecunda, Salisb., 
E. Thunbergii, Montin, and E. inflata, Thunb., all ob- 
viously different from E. Haroldiana, though E. 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. E. Haroldiana 
seems to be quite happy and is making good growth, 
under the cool greenhouse treatment accorded the other 
members of this genus from S. Africa.

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 l\ 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 

Janlwry-Mauch, 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 go on 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. F&rrestii 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.

The striking Campinulaceous species now figured was 
first described by Mr. Xakai in 1909 as a Symphandra. 
Two years later its author came to the conclusion that it 
represents a distinct genus which he named Hanabusaya. 
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 anj^ 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 confined 
to South-eastern Europe, the Caucasus, Armenia, Lazistan 

January-March, 1920. 



and northern Persia, and the species to which the Corean 
S. asiatica is most closely related is the Candian S. cretica, 
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 Pavetta 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, P. caffm, 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 

January-March, 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- 
pala in Uganda, where it is also wild, as a species of 
Clerodendron ; for its introduction to cultivation 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 Lvora 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 If in. wide, but sometimes 9-10 in. long by 4 in. across, margin 
undulate, thinly papery, at first setulose but soon glabrous above, laxly hairy, 
especially on the nerves beneath ; lateral nerves 12-14 on each side of the 
midrib which they leave at a wide angle, pale on both surfaces and raised 
beneath ; petiole usually about 2 in. long, but in large leaves \\ in. long, laxly 
hairy ; stipules almost membranous, caducous, | in. long, long acuminate, 
densely villous on the inner 'face. Inflorescence nearly sessile yet laxly 
flowered, including the far exserted styles about 5 in. across ; pedicels about 
I in. long, glabrous. Calyx with a narrow cylindric tube-'- in. long, glabrous; 
lobes 4, linear, i in. long, sparingly hairy or nearly glabrous. Corolla 
white ; tube f in. long, glabrous outside, shortly hairy within ; lobes 4, oblong- 
lanceolate, acute, about f in. long. Anthers slightly exserted, green, J in. long, 
mucronate. Style 11 in. long, shortly and softly pubescent towards the tip 
which is stoutly 2-fid. Fruit black, shining, globose, about $ in. across, 
crowned by the persistent calyx-lobes.

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 Plmrothallis for the glaucous hue of 
the leaves, due to a dense coating of greyish-white 
farina. It is also curious en 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-March, 1920. 



shows that the character is as constant as it is peculiar. 
There are other features of an anomalous 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 Macrophyllae-Fasciculatae as denned 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, 1902. 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.

slender, 2-3 m. long, clothed halfway up with narrow tubular sheaths, 1-foliate. 
Leaves shortly petioled, ovate-elliptic, rather acute, coriaceous, copiously mealy-

The very interesting Ribes 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 
Maximoiviczii, 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 R. Maximowiczii, only 
knew the latter in the fruiting condition, and, although he 
placed it in the section Bensia, was disposed to believe 
that it may really belong to his section Par ilia. There 
seems now no doubt, however, that the arrangement 
actually adopted by Janczewski is correct, for the plant 
now figured as R. 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 Eerisia, 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 Beriaia to 
which it belongs contains seventeen species, most of them 
Chinese, though it includes also the well-known A\ 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 3-5-lobed, the lobes often shallow, 
rarely absent, the margin at the same time coarsely twice serrate, 2J-4 in. long 
and broad, sparingly beset with short hairs above, softly hairy beneath 
especially on the nerves ; petiole J-lf 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, \-\ in. long, pubescent 
and sparingly glandular ; pedicels ±-\ in. long, also pubescent and glandular. 
Male flowers saucer-shaped. Receptacle T ^ in. long, pubescent and glandular 
at the base. Calyx deep tawny red ; lobes rather rounded, A | in. long. 
Petals minute, spathulate-unguiculate, the claw linear, the limb A in. across. 
Stamens ^t in. long ; filaments slightly dilated at the base. Styles of the 
imperfect ovary T ^ in. long, connate at the base, as long as the petals. Female 
floivers resembling the male, but with the receptacle of the inferior ovary ovoid, 
finely villous and densely clothed in addition with glandular bristles \ 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. Fruit 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 
■^ in. across, brown, faintly marginate.

The new Rhododendron here figured was received as a 
seedling from the Jardin des Plantes at Paris in 1889, 
under the name R. decorum, Franch., and was raised there 
from seed sent by Delavay from China where R. decorum 
is a native plant. There are, however, many differences 

April-June, 1920. 



between the species described by Mr. Franchet and that 
now described as E. serotinam. 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 
R. serotinum from R. decorum. From R. Fortune!, Lindl., 
another close ally and a member of the same natural 
group, R. .serotinum differs especially by its hairy 
filaments. From both species mentioned R. serotinum 
may be distinguished by its blotched corolla, an unusual 
feature in the group to which all three belong. Out of 
doors R. 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, li-lj-" 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 vemlets but dense and crystalline between the veinlets ; lateral 
nerves about 16 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 j 
petiole f-l£ m. long, glabrous, nearly cylindric, about \ in. thick. Inflorescence 
shortly racemose, terminal, 7-8-flowered ; axis 1£ in. long, minutely glandular- 
papillose; bracts pilose externally; pedicels H-1J in. long, 1 in. thick, pale 
straw-coloured and flushed with rose, minutely glandular-papillose. Calyx 



oblique, about J in. across, undulately lobed, covered outside and on the margin 
with minute red sessile glands. Corolla somewhat nodding, fragrant, white 
slightly flushed with rose outside ; within the back of the tube blotched and 
tinged with red; tube wide funnel-shaped, lj-lf in. long, with white-stalked 
glands outside ; lobes 7, spreading, wide suborbicular, widely notched at the 
tip, about f in. long and 1\ in. across. Stamens 15-16, unequal, the dorsal 
the shorter, up to If in. long; filaments white, shortly pubescent below; 
anthers pale brown, about \ in. long. Ovary 10-locular, oblong-ovoid, \ in. 
long, clothed with white shortly-stalked glands ; style rather longer than the 
stamens, 1^-lf in. long, white, crowned by the ellipsoid or suborbicular viscous 
pale green stigma, which is about 1 in. wide.

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 

April-June. 1920. 



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, 1^-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, f-1 in. long, acuminate and recurved 
at the tip ; pedicels about f 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 1^-lf 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. 
Column wide, very short ; wings ovate, falcately acuminate, over } in. long ;

Hoheria populnea was originally discovered by Mr. C. 
Eraser in 1825, and again by Mr. K. 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 Hoheria in the often unisexual flowers, the linear 
decurrent stigmas and the solitary carpels. //. 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. In a 
third variety (angustifolia, Hook, f.) many leaves are only 
an inch long 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 Iloheria 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 Richards, 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 late-flowering 
trees. It thrives in loamy soil and can be propagated 
by cuttings. 

Description.— Tree of small size, 10-30 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, 
i-li in. wide, glabrous or with very scattered stellate pubescence beneath, rich 
lustrous green above ; petiole J-J in. long, stellately pubescent. Flotvers in 
fascicles, produced during late summer in the leaf-axils of the current season's 
twigs, f-1 in. diameter. Calyx grey-pubescent, turbinate, 5-lobed, the lobes 
triangular, acute, ^ in. long, reflexed at the fruiting stage. Petals 5, snowy- 
white, oblong-obovate, often unevenly lobed towards the apex, g-§ in. long, 
i 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, I in. long, pinkish, and furnished with 
stellate pubescence.

The handsome IrU 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. K. 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 Regeliana^ in foliage closely 
resembling /. Korolkowit, Reg., from Turkestan (figured 
at t. 7025 of this work), and 1. stolonifera, Maxim., from 

April-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 Iris 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 
1. Boogiana, 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 Iris 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 f 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, 2^-3^ in. Pedicels very short. Perianth-tube green, 
streaked with purple, about 1J in. long, reaching the top of the spathe ; outer 
segments with a reflexed rounded-obovate quite blunt, uniformly clear lavender- 
violet limb, If 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, 1J 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 
Arctotis 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

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 Drege, 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, 1J ft. high, 
sparingly pubescent throughout with many-celled hairs, sparsely leafy low

The Myrtaceous genus Metrosideros is widely distributed 
throughout Polynesia and is well represented in New 
Zealand. The species now figured, M. collina, though 
not one of the New Zealand members of the genus, is 
most nearly allied to M. 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 

April-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 polymorplia 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- 
morplia includes five species, four of these being endemic 
in the group, while the fifth is the widespread M. 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. — Tree, 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, 
cuneate or rounded at the base, villous or glabrous, 1J-2J in. long, £-l£ in. 
wide ; veins many, parallel ; petiole i-f in. long. Flowers terminal, showy, 
rather closely corymbose or paniculate ; bracts almost obsolete ; pedicels short, 
tomentose. Calyx campanulate, 1~| in. long, tomentose ; lobes wide, oblong 
or rounded, ^ in. long. Petals obovate, ±-\ in. long, red. Stamens nurrferous, 
§-§ in. long. Style slender, f in. long.

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 

April- June, 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 L. Duchartrei, Franch., figured at 
t. 8072 of this work. The features which especially 
characterise L. Farreri are its linear-lanceolate cauline 
leaves which are disposed throughout the greater part of 
the stem, and its relatively small flowers whose re volute 
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 inch in 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. Farreri 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 
T ^ in. thick, with white naked internodes up to 3 in. long, bulbiferous at the 
nodes ; young bulbs wide ovoid, acute, over \ in. long and nearly as thick, 
loosely or closely clothed with a few broad thick scales. Stem erect, 2£-2J ft. 
high, firni, 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, 3£ in. long, 
over A 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 I 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 2 in. wide, white with dark purple 
blotches in the lower half, forming at the base a green tube less than i 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 
14 in. long, curving outwards, glabrous ; anthers about \ in. long, tawny. 
Ovary cylindric, over ^ in. long, I in. across, longitudinally sulcate, glabrous, 
green ; style gradually thickened upwards, curved outwards, about 1£ in. long,

The Chinese Salvia described by the late Mr. Franchet 
as S. brevilabra was first collected near Ta-chien-lu in 
Western Szechuan by Pere Soulie 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 

April-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. brevilahra 
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. 
Leveille as S. Blind, and although Dunn has reduced 
S. Blinii to S. brevilahra, it is not altogether certain that 
Leveille's plant is identical with that of Wilson. The 
plant which Leveille 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. brevilahra 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. Mans, Royle, 
figured at t. 6517 of this work, which differs mainly from 
S. brevilahra in having much larger corollas with longer 
lips, and in having leaves which are usually more regularly 
and less coarsely toothed. Plants of S. brevilahra, 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.

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, 

April-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 Ribes 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 R. niveum may have been one of the 
" interesting species of Ribes " 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 Ribes, 
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. R. 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 J in. long, or unarmed; stout suckers rarely sparingly 
prickly. Buds oblong, -J- in. long ; outer bud-scales somewhat leathery, 
brown, triangular-ovate, rather acute ; inner scales scarious, elongated, pale-

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 plemnthum, 

Apeil-Jdne, 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 
Easteru United States, figured at t. 1819, and in its 
Himalayan representative P. Emodi, 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. Emodi, var. 
ckinense, 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. Emodi 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 P, Emodi proper, and its variety 
ckinense, are connected by the variety Royleanum, Wall. 



{P. hexandrum, Royle) which has leaves intermediate in 
character. The flowers of true P. Emodi and of its 
variety Boyleanum are usually white, but may occasionally 
be pink. 

Description. — Herb, perennial ; rootstoek stout, horizontal, sending up 
annual leaves and erect annual flowering stems; roots many, adventitious, 
fleshy, reaching 8 in. in length. Stems fleshy, 10-12 in. high, about } in. thick, 
clothed at the base with numerous cataphyllary sheaths, 2-3-fohate above with 
the internodes at time of flowering |-f 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

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,

The Rhododendron now figured was first discovered 
by the Abbe 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 

April- June, 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, R. lutescens 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, 11. 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 R. lutescens is hardy at Kew, where it grows 
freely in peaty soil or in sandy loam. 

Description. — Shrub, 6-8 ft. high, somewhat fastigiate in habit, with the 
purplish -brown branches and twigs which are sparingly black-lepidote in their 
first season, all ascending. Leaves lax, wide lanceolate or almost ovate- 
lanceolate, acutely gradually acuminate, base bluntly cuneate, 2-3 in. long, 
-f-1 in. wide, green, usually with reddish margins, polished above and sparsely 
lepidote, paler beneath and rather laxly lepidote with the golden yellow unequal 
scales sometimes deciduous ; midrib sunk above, raised beneath, hardly lepi- 
dote ; lateral nerves about six on each side the midrib, inconspicuous, flexuous ; 
petiole about -*- in. long, brown, sparsely lepidote. Flowers axillary, usually 
solitary, clustered towards the tips of the flowering-shoots ; bud-scales brown, 
almost membranous, lepidote outside, acutely and abruptly acuminate, finely 
puberulous on the margin and within ; pedicels about \ in. long, lepidote. 
Calyx very short, undulately lobed, densely lepidote outside. Corolla in- 
distinctly 2-lipped, yellow or greenish -yellow, punctate with pale green spots 
within the tube behind ; tube open, over £ in. long, sparingly lepidote outside, 
stoutly pubescent within ; lobes 5, unequal, ovate, up to % in. long, sparingly 
lepidote outside. Stamens 10, declinate, far exserted, very unequal, the 4 upper 
filaments shorter than the rest and densely villous just above the base, the 
6 lower much longer and glabrous ; anthers golden-yellow, -fo iu- long. Ovary 
5-celled, densely lepidote ; style curved, pale green, glabrous, slightly larger 
than the lower stamens, crowned by the lobulate viscid stigma.

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 A r . 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 N. 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 N. luteum ; 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.

The large and very distinct Pleurothallis here figured 
is 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 Racemosae, 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 

Juxy-Septpmbkr, 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. 

Description.— Herb, epiphytic, over U ft. high ; stems elongated, cylindric, 
1-H ft. long, sparingly clothed with tubular keeled sheaths 3-3£ in. long.

The Cotoneaster here figured was raised in the garden 
of Mr. G. H. Cave, Rod way 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 C. 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 

Joly-Septembeb, 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 in a 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, 
becoming glabrous and polished by the second season ; bark brown, cracking 
longitudinally. Leaves elliptic or obovate elliptic, tip acute and abruptly 
apiculate, base shortly cuneate, lf-3 in. long, 1-1 1 in. wide, papery, finely

Daphne tamjutka was originally discovered by the 
famous Russian traveller, Przewalski, in Kansu, Western 
China, in 1873, but was not described and named by 
Maximo wicz until ten years later. Although quite 
distinct in its general aspect from D. return, Hemsl., 
figured at t. 8430 of this work, it is undoubtedly very 
closely allied to that species. In D. return, however, the 
leaves are shorter and proportionately broader, the 
perulae are more markedly ciiiate, and the stigma is 
distinctly pubescent. Mr. Render, in " Plantae Wilson- 
ianae," relies on the "ramuli glabri" of D. tangutica to 
separate it from D. return, but the young shoots of both 
are at first covered with small strigose hairs. Judging 
from the rather scanty material as yet available, the 

July-September, 1920. 



umbels of D. tangutica are smaller than those of D. return, 
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 tuff 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. 

Description. — Shrub, probably not exceeding 3-4 ft. high, densely branched 
and of sturdy rounded form ; young shoots stout, greyish -brown, at first 
clothed with pale grey bristles, at length becoming nearly glabrous. Leaves 
persistent, leathery, oblanceolate or narrowly elliptic, usually emarginate at 
the apex, narrowed at the base to a short stout petiole, margin slightly 
revolute, glabrous on both surfaces, dark rather glossy green above, paler and 
dull beneath, 1-3 in. long, J-| in. wide. Floivers in terminal umbels 1J in. in 
diameter, opening in April or May from the axils of oblong, pointed, ciliate but 
otherwise glabrous bud-scales. Perianth glabrous, 4-lobed, with a tubular 
base, rosy-purple outside ; tube § in. long ; limb £ in. wide ; lobes ovate 
obtuse, white inside, two of them stained with purple towards the tips. 
Stamens 8, in two superposed series of 4 each ; anthers yellow, about thrice as 
long as the filaments. Pistil | in. long; ovary glabrous, ovoid; style very 
short and thick ; stigma capitate, glabrous or nearly so. Berry red, fleshy, 
ovoid-globose, § in. long, i in. wide.

This very distinct Coelogyne 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 C. 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, 

July-Septembbr, 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, 2-3* 
in. long, 2-foliate. Leaves elliptic-lanceolate, acute or shortly acuminate, 
prominently 3-5-nerved, narrowed below to a distinct petiole, 6-7 in. long,

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. S. 
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. atroearpa, basing his differentiation 

July-Shptember, 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 

J>. 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 
:{-li in. long; internodes 1-2J in. long. Leaves evergreen, in clusters of three 
to eight at each node, coriaceous, glabrous, elliptic-lanceolate, lj-3i in. long, 
4 -;, in. wide, acute, slenderly cuneate at the base, subsessile or with a petiole 
up to J m. 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, I to ) in. in diameter ; pedicels J to i in. long, slender, terete, glabrous. 
bepalso\a.\. Petals bifid at the apex. Fruit ovoid to oval, g 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 Rhiz iridium 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 

July-September, 1920. 



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. 
cj/aneum, var. hrachystemon, 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 
successfully 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 having only their alternate filaments 
toothed at the base. 

Description.— Herb, bulbs tufted, vertical, cylindric, sometimes as much as 
A in. long, the outer sheaths with age fibrous. Leaves 2-3, superposed,

The genus Sabia, 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-September, 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 1S90, 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 
hardy. 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° S. in Queensland to about 
34° S. 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 wnich 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.

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 
oi Ichen-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 
lnis 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 

™ Ke 7m2 19 i 7 fr0m Mr ' de Vilmorin and flowered in 
May, 1919. The leaves of A. Fargesii resemble those of 
A. nngens, 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

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 S. 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

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. 

Description. — Shrub or small tree with densely grey-tomentose young twigs 
which become dark-purple and adpressed pubescent in the following season. 
Leaves linear-lanceolate, narrowed to both ends, acuminate or long mucronate 
at the tip, quite entire, 1^-3^ in. long, f-f in. wide, thinly papery, pubescent 
along the midrib above, elsewhere glabrous ; lateral nerves about 12 on each 
side the midrib which they leave at a wide angle, raised beneath, 2-furcate 
towards the leaf- margin ; petiole over I in. long, densely adpressed-pubeseent ; 
stipules very early deciduous. Corymbs about 3 in. across, dense-flowered, 
with the peduncle and pedicel densely pubescent. Receptacle wide campanu- 
late, sparingly pubescent, about T V in. long. Sepals wide ovate, minutely 
mucronate, ciliolate. Petals white, orbicular. Stamens about 20, anthers red. 
Ovary pubescent above; style ± in. long; stigmas capitate. Fruit red, 
depressed-globose, about I in. across.

CURTIS'S BOTANICAL MAGAZINE. 

In consequence of the increased and 
still increasing eost of producing CurtiYs 
Botanical Magazine, the Publishers propose to 
terminate the fourth series with the present 
issue, Vol. 16 (1920), or Vol. 140 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.So., F.L.S., 

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. 

It 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 1st, 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 
Octobxb-Dbcembkk, 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.— ilerfc, biennial ; stem l£-2 ft. high, with 2-3 branches towards 
the top, glabrous downwards, slightly and finely glandular high up. Leaves 
of the rosette linear-lanceolate, acute, narrowed to the petiole, 8 in. long,

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 Abbe 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 

October-I)kcf:mi5f.i;, 1920. 



early weeks of 1920 however brought the blossoms of 
i?. 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 R. strigillosum is 
readily distinguishable by its very bristly young shoots. 

Description.— 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-lanceolate, acutely acuminate, slightly narrowed and shortly 
cordate at the base, 3-6 in. long, f-li 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 J-f in. long, 
setose-hispid and tomentose. Inflorescence terminal, about lO-flowered ; 
bracts densely woolly outside ; pedicels about | in. long, densely setose with 
black gland-hpped hairs. Calyx short, setose outside. Corolla red, with 
5 black basal blotches inside; tube narrow campanulate, glabrous outside, 
q# ^ g ' 1 m ' wide at the tbroa * ! lohes 5, rounded, emarginate. 

btamens 10 exserfced ; filaments pale purple, glabrous, about 1} in. long; 
antners nearly black, \ in. long. Ovary 5-eelled, densely strigillose ; style

The interesting Fritillaria 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 Cots wold, Parks tone, the 
plant figured having been raised from a bulb sent from 

Octobkr-Dkokmhkr, 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 F. pontica flourishes under the 
shelter of bushes at about 3,C00 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 high wall, produced plants which flowered 
when a foot high, formed capsules and matured seeds, 
in a soil suitable for other species of Fr iti liar ia 'and if 
given sufficient shade, F. pontica is likely to prove hardy, 
lhe 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.

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 Eucalyptus, 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 Manuka of 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, 

OcTOBER-DliCKMBER, 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, M. 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 
b wan River district by Mr. James Drummond, and was 
hrst described from his specimens by Professor Lindley. 
Its natural range appears to be rather limited, though it 
is not uncommon within its special area, for it has since 

I A^ e ^°° llcCted by Preiss near the Cunning River, 
t>y Oldneld at Champion Bay and on the Murchison 
Kiver and by more recent travellers in neighbouring 
aistricts. Its nearest ally in the genus is M. linearifolia, 
bmith .another species from Western Australia, 'from 
which M. Radula is readily distinguished by the involute 
ieat-m ar g inS5 and by the larger flowers which are never, 
as in M. linearifolia, arranged in a terminal panicle.

The Kniphofia 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 

OCTOBSB DbCEHBEB, 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 Kniphqfia, 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. longl- 
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,

This South African Heath is rather widely spread in the 
Coast Region of Cape Colony. It has been frequently 
reported from the Cape, Stelienbosch, 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 

( >ctobeb-Dbcbmbeb. 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 in a greenhouse at Kew in June, 1919. A 
plant of sturdy habit and robust growth, E. seas Hi flora 
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 E. gilva, Wendl., from 
which it is easily distinguished by ' its sessile flowers 
and different corolla. It is readily separated from E. 
Broadleyana, Andr., and E. Boicieana, Lodd., by its dense 
close spike, from E. mammosa, Linn., by the corolla 
being terete at the base, and from E. ftlipendula, 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 18S9, was not 
described till 1910, when specimens collected by Mr. 
E. 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 

October-Decejibee, 1920. 



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 Oleaccae 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 S. reflexa thrives in rich loamy soil, and can be 
increased by cuttings of leafy shoots put in gentle heat 
towards the end of July.

This handsome Phlomis was first discovered in 
Kashmir by Victor Jacquemont during his travels in 

October-Decembek, 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 Pldomis now comprises 
over eighty species, about twenty of which are or have 
been in cultivation. The well-known P. 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. oreophda, 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 
{Eupfdomis) of the two sections into which the species of 
Phlomis are grouped. The Mowers are, however, much 
more correctly described in the definition of the sec- 
tion Phlomidopsi.% which includes P. tuberosa and 
P. macrophylla, species obviously closely allied to P. 
spectabilis. 

Description.— Herb, perennial. Stem erect, sparingly branched, stout, 
cylindnc, about 6 ft. high, J-4 in. thick, sometimes at first more or less 
stellately hoary-tomentose, rarely sparingly hispid, at length glabrous and 
often glaflfcous; internodes long, sometimes over' 8 in. long. Leaves petioled, 
ovate-cordate, subacute or rounded at the tip, deep and widely cordate at the 
base or in the upper parts of the stem, cuneate or rounded, coarsely and 
irregularly toothed or at times faintly lobed, upper leaves often almost 
regularly dentate or serrate, green and sparsely pilose above, stellately hoary- 
tomentose beneath, main-nerves conspicuous; basal leaves 8-12 in. long, 
6-11 m. wide; petiole hispid, 6-12 in. long; stem leaves gradually smaller 
upwards, the lowest 6 in. long, over 4 in. wide, with petiole from i-4 in. long, 
the uppermost reduced to bracts. Flower-whorls 3-9, most often 4-6, 2-6 in. 
apart, sometimes 30-flowered. Bracteoles acicular, over J in. long, sparingly 
hispidulous. Calyx tubular funnel-shaped, about 1 in. long, sparsely 



beset with short rather stiff stellate hairs, 10-nerved, widely 5-lobed, lobes erect, 
very short, emarginate, the 5 strongest nerves produced into awns }~i in. long. 
Corolla pale rose-purple, with the midlobes of the lower lip deeper in shade ; 
tube tubular funnel-shaped, as long as the calvx, with a ring of hairs at the 
base within; upper lip gaping, oblong-obovate, nearly | in. long, over } in. 
wide, sparingly toothed at the tip, densely villous on the back, densely white 
bearded within and on the margin ; lower lip spreading, 3-lobed, f in. long, mid- 
lobe orbicular-obovate, marginate,over |in. wide, side-lobes ovate, i in. long, a in. 
wide. Stamens far exserted, nearly equal ; filaments curved, sparingly woolly, 
the 2 posterior with a curved linear basal spur about } in. long ; anthers 
glabrous. Style glabrous, rather longer than the stamens, unequally 2-fid. 
Nutlets (unripe) subglobose, sparingly glandular-hairy at the apex. Disk fleshy, 
white, sharply 4-denticulate.

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 R. 

October-December, 1920. 



etphahnthum, 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. S. Balfour of Dawyck, Peebleshire, in March, 1914. 
It flowers in May. 

Description.— UndersJirub, 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,

This distinct and striking Mesembryanthemum 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 Calamifurmia, 
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 

October-December, 1920. 



may eventually be found to be necessary. M. dkhroum 
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. 

Dbscbiption.— HerJ, with short simple or sparingly branched suberect stems, 
6-6 2 in. high. Leaves 4-5, spreading, linear-oblong, acute, 3-quetrous, thick,

The history of this handsome Odontofjloswtm 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 0. Rossii and 0. cordatum, two Mexican 
species described by Professor Lindley. Three years 
later another plant flowered with Messrs. J. Veitch and 
Sons. This Reichenbach described as 0. a&permm, again, 
however, in the belief that it was a hybrid, but with the 

October-December, 1920. 



suggestion that while 0. Rossii is one parent, the other 
might be 0. macalatum, a Mexican species named by La 
Llave. Subsequent importations of 0. Rossii have in- 
cluded a certain proportion of individuals that on flowering 
have suggested some admixture with 0. 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. S. 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 0. aspersum 
being overlooked. The confusion of these two species 
themselves, for the plant figured as 0. maculatum at 
t. 4878 is really 0. 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 0. Ilumeamnn 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 0. Rossii and 0. 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 small 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. 

Description.— H«*, epiphytic ; pseudobulbs clustered, ovoid-elliptic, some-
