The stately Cycad here described and figured was first 
discovered by Sir John Kirk near Dar-es-Salam on the 
East African Coast in 1868. The material originally 
sent home consisted of some pinnae and a few seeds and 
proved too incomplete for description. Two years later 
he made the first attempt to introduce the plant to 
European cultivation, but the stem which he sent home 

January, 1915. 






in 1870 unfortunately did not survive the journey. 
Later in the same year Kew received from Sir John a 
supply of seeds and some of these germinated, one of 
the plants of this introduction being in the Kew collection 
in 1881, growing alongside a fine male stem which was 
successfully transported to this country in 1878. In 
1884 Sir John Kirk was again able to transmit a male 
and also a female stem, both of which have thriven well 
under the conditions suitable for other tropical Cycads 
in the Palm House at Kew, where they are still in 
vigorous health and growth. From these have been 
obtained the material from which the two plates here 
given have been prepared. 

In the meantime, however, the distinguished traveller 
Mr. J. M. Hildebrandt had also met with the species on the 
East African Coast over against the island of Zanzibar, 
and at other points on the same coast as far north as 
Mombasa. From the material obtained by him it was 
described, as Encephalartos Hildebrandtii , by Professor 
Braun and Mr. Bouche in 1874, and between 1874 and 
1876 Hildebrandt secured and transmitted to various 
European gardens a large number of stems. Relying on 
the appearance of some of these, the late Professor Kegel 
in 1876 suggested that the East African plant might 
prove to be no more than a local form of the Natal 
species, E. villosus, Lem., of which an account has been 
given at t. 6654 of this work. The controversy thus 
raised was taken up by Braun who pointed out the 
differences between the two species, and in 1880 Pro- 
fessor Eichler confirmed Braun's observations and even 
suggested that the difference in the shape of the female 
cone-scales justified the location of the two in distinct 
sections. In 1890 Professor Hennings, however, on the 
strength of a female specimen grown in a nursery at 
Schomberg, near Berlin, which showed characters that 
led him to consider it a connecting link between the 
Natal and the East African plant, reverted to the view 
expressed by Regel. The matter has again been very 
fully discussed by Dr. Stapf in the Kew Bulletin for 
1914, and the conclusion to which he has come, that the 
view of Braun and Eichler is sound, while that of Regel 
and Hennings cannot be sustained, seems incontrovertible. 




The pinnae figured on t^ 8592 are rather wider than is 
usual in this species. 



Description. — Tree with a cylindric stem, sometimes 
very short or at times up to. 20 ft. in height, 1 ft. in 
diameter, closely beset with persistent imbricating leaf- 
bases. Leaves suberect or — at least in cultivated speci- 
mens — with the outer spreading, rigid, slightly recurved, 
up to 9 ft. in length, 1 ft. wide, petiole and rachis at first 
woolly but soon becoming glabrous and ultimately quite 
smooth, terete ; pinnae 50-70 along each side increasing in 
size from the base to the middle, the central ones obliquely 
linear-lanceolate, with acute spinescent tips, up to 9 in. 
long, f-1 in. wide, with from 4-1 (usually 2-3) spines 
on each side, the uppermost spine generally some distance 
below the tip, rigidly leathery, quite glabrous, indistinctly 
parallel-nerved, the lowermost pinnae very short and 
coarsely spinous-toothed. Male cone pedunculate, cylin- 
dric, 8-18 in. long, 2J-4 in. thick ; scales as seen from 
behind wide-obovate, with dilated rhomboid tip, -§-£ in.

red or greenish-red, their lateral angles acute, above and 
below blunt, marked by a transverse raised fine and by 
a second ridge extending from the upper angle to the 
middle; peduncle up to 3| in. long, woolly, sparingly 
scaly. Female cone subsessile, cylindric, up to 2 ft. long and 
7 in. thick, leather-yellow; scales as seen from behind 
anchor-shaped, the head up to 2 in. wide and 1 in. long,

The Cotoneaster which forms the subject of our figure 
was discovered in 1886 on limestone mountains in South- 
western Yunnan at altitudes of about 8,000 feet above 
sea-level by the late Abbe Delavay. Young plants were 
raised in 1888 from seeds sent by him to the Jardin des 
Plantes, Paris, whence, six years later, the plant from 
which material for our illustration has been prepared 
was sent to Kew. In collections C. pannosa is sometimes 
confused with C, Franchetii, Bois, to which it is closely 
allied. Both have the same marked elegance in growth 
and both are characterised by a thick tomentum on the 
young shoots, lower surface of the leaves, pedicels and 
calyx. But C. pannosa is readily distinguished from C. 
Franchetii by its smaller leaves with longer petioles, purer 
white and more spreading petals, and smaller fruits of a 
duller deeper red. In the fruiting spray depicted on our 
plate it will be observed that the majority of the fruits

are oval, only those towards the ends of the branches 
being globose or nearly so. Sometimes, however, the 
proportion of globose to oval fruits is reversed, and taken 
generally, globose fruits outnumber those that are oval. 
Few shrubs are better adapted for a poor natural soil, 
such as that of Kew, than the Cotoneasters, and C. pan- 
nosa is no exception to this rule. It is perfectly hardy 
and thrives admirably in loam of good or even moderate 
quality. Propagation is easily effected by means of late 
summer cuttings in gentle heat or, more slowly, by the 
seed of which it produces such plentiful crops. This and 
other species of the genus are to be recommended for 
gardens situated on calcareous formations.

Mesembryanthemum, Linn. ; Benth. et HooJc.f. Gen. Plant, vol. i. p. 853 



Mesembryanthemum thecatum, N. E. Br. ; species nova M. fraterno, 
N. E. Br., affinis, sed plantulis coeruleo-viridibus punctis uiinoribus et 
minus conspicuis floribus roseo-purpureis et starninibus paucioribus 
differt. 

Herba parva, acaulis, succulenta, caespitosa, glabra. Folia in corpuscula 
obconica, apice leviter convexo-truncata, 7-10 mm. diametro fusa, coeruleo- 
viridia, punctis sordide viridibus conspersa, fissura centrali 3 mm. longa, 
pedunculos et ovaria includentia. Calyx tubulosus, apice 4-lobus, mem- 
branaceus, albidus ; lobi ovati vel obovati, obtusi. Corolla gamopetala, 
1'2-1'5 cm. diametiens, roseo-purpurea, luteo-oculata ; petala difformia, 
exteriora 12-16, 2-seriata, 6-8 mm. longa, 1*5-2 mm. lata, cuneato-linearia, 
apice obtusa vel denticulata, roseo-purpurea ; interiora 12-16, brevissima, 
linearia, acuminata, lutea, interdum apice roseo-purpurea. Stamina 8, 
2-seriata, medium tubum corollae attingentia, lutea. Stylus 1 ' 5-2 mm. 
longus, starninibus brevior, apice 4-lobus, viridis. — N. E. Brown. 



The pleasing little Mesembryanthemum here for the first 
time described belongs to a group of species in that 
large genus characterised by each branch or division of 
the plant bearing at any one time but one pair of leaves 
which are united for the whole or for part of their extent 
into one mass, technically termed a " corpusculum." 
When a fresh pair of leaves, united in a new corpusculum, 
is being formed, the pair of the previous growth gradually 
shrivel to a papery consistence through which the new 
growth bursts. In the case of M. thecatum, depicted in 
the upper half of our plate, the two leaves of each suc- 
ceeding growth are united throughout and completely 
envelop the peduncle and ovary, leaving at their apex 
a mere fissure from which the actual flower protrudes. 
The species is one of the novelties discovered by Professor 
Pearson, Director of the National Botanic Garden of 
South Africa at Kirstenbosch near Cape Town, in the 
course of his very fruitful journey to the Orange River 
undertaken in 1910-11 under the auspices and with the 

January, 1915. 



assistance of the Percy Sladen Trust. It was met with 
growing on dry ridges south of Bakhuis in the Van 
Rhynsdorp Division of Cape Colony, and the plant from 
which our figure has been prepared formed part of a 
very valuable collection of succulents collected by Pro- 
fessor Pearson and his fellow-traveller on the expedition, 
Mr. N. S. Pillans, which was presented to Kew in 1911. 
It has thriven well and flowered freely under the con- 
ditions suitable for Mesembryanthemums generally. Its 
flowers open in the morning and close at night, and are 
devoid of scent ; each flower lasts from four to six days. 



Description. — Herb, small, stemless, succulent, tufted, 
glabrous. Leaves consolidated in obconic bodies, some- 
what convex-truncate at the tip, about \ in. thick, 
bluish-green with dull green markings, central chink ^ in.

types, the outer 12-16 are 2-seriate, 1~J in. long, T ^ in. 
or less in width, linear-cuneate with blunt or denticulate 
tips, rose-purple throughout, the inner 12-16 are very

Hcrba parva, acaulis, succulenta, laxe caespitosa, glabra. Folia in corpuscula

The interesting Mesembryanthemum which occupies the 
lower half of our plate is another of the fruits of the 
Percy Sladen Memorial Expedition to the Orange River, 
led in 1910-11 by Professor Pearson of Cape Town. 
Like its companion this species, M. stylosum, is a hitherto 
uncharacterised one, belonging to the same natural group, 
though in this instance the welding of the two leaves 
forming each corpusculum is much less complete and the 
resultant bodies are deeply 2-lobed at the apex. M. 
stylosum was collected on the plains between Chubiessis 
and Stinkfontein in Little Namaqualand, and the plant 
from which our illustration has been prepared formed 
part of the same munificent accession to the succulent 
collection at Kew for which the institution is indebted to 
the Percy Sladen Trust and to the travellers who, thanks 
to their assistance, were enabled to investigate so 
thoroughly the vegetation of a considerable portion of 
western Cape Colony. The flowers in M. stylosum are 
bright yellow; they open in the day time and only in 
bright sunshine. They last for five to six days and are

The large Bromeliad here figured is a native of the 
forests in the provinces of Rio Janeiro and San Paulo in 
Southern Brazil and has been in cultivation in Europe 
for upwards of half a century. There are excellent 
figures of the plant published by Antoine from an 
example which flowered in the Hofburg Gardens at 
Vienna in 1874, while it has since then been figured 
several times, occasionally under synonyms other than 
the accepted name Tillandsia Regina, Veil. This variety 
of names has been due to the circumstance that the 
plant itself exhibits some degree of variation ; its flowers 
may be white or yellow and sometimes change from the 
former to the latter colour during the flowering period. 
T. Regina has been in cultivation at Kew for many 

Fkbruary, 191"). 



years. Thirty years ago there was a large plant in the 
Victoria regia House, where it was grown in a pot over 
the lily tank. The plant from which the material for 
our figure has been derived was raised as an offset from 
the original plant and was about thirty years old when 
it flowered in the Mexican Section of the Temperate 
House, Kew, in May, 1912, dying down soon afterwards. 
It is of interest to note that in July, 1912, another plant 
of the same species flowered in the Royal Botanic 
Garden, Glasnevin. A sufficient supply of seeds has 
been matured so that it has been possible to raise a 
stock of young plants. T. Regina belongs to the section 
Vriesia, which differs from fdlandsia proper in having 
scales at the base of the petals within. The only species 
with which it has been confused is T. imperialis, C. H. 
Wright, which is readily distinguished by the flowers 
being secundly disposed on the branches. There is 
another species of the same section, even more closely 
allied to T. Regina, which has been figured at t. 8192 of 
this work. The species in question, T. Blokii, Hort., is 
however, easily recognised by its leaves with red blotches 
and its blood-red bracts.

The striking Orchid which forms the subject of our 
illustration belongs to the genus Mormodes, which is 
most nearly allied to Catasetum, Rich., but differs there- 
from in its hermaphrodite flowers, and in the oblique 
twisting to one side of the lip, the margins of which are 
also sharply recurved so as to form a tube which rests 
upon the equally oblique apex of the column, ihe 
method of fertilisation was discussed by the late 
Mr. Darwin. The species was originally discovered _m 
the forests of the Rio Negro and was described m lh / < , 
from specimens collected there, by the late Mr. Barbosa 
Rodrigues. Some twelve years afterwards it was agam met 
with in the Rio Negro district and was then introduced 
to cultivation by Messrs. Sander and Sons, St. Albans,

At 



later date it was introduced afresh, this time from 



FXBBUABT, 1915. 



Amazon district, by Messrs. Hugh Low and Company. 
The plant from which our plate has been prepared is one 
which was purchased, when in flower, in February, 1914, 
for the Kew collection from Messrs. Sander. It formed 
part of a recent importation, once more from the Upper 
Amazon district, though the precise locality is not 
indicated, sent to St. Albans by Mr. Forget. The 
nearest ally of M. tigrinum is M. igneum, Lindl., a 
Peruvian species from which it is distinguished by its 
differently coloured flowers with a shorter lip. Both 
species thrive well in a tropical house under the conditions 
suitable for species of Catasetum.

The pleasing Rhododendron here figured is a native of 
the mountains of Szechuan in Western China, where it 
occurs at altitudes of 6,000-10,000 feet above sea-level. 
It was first found in 1870, in the neighbourhood of Mou- 
pine, by the late Abbe David. It was again met with 
on Mount Omi and on neighbouring mountains by Mr. 
E. H. Wilson in 1908, and our figure has been prepared 

February, 1915. 



from a plant raised from Wilson's seed of this last 
gathering, received at Kew from the Arnold Arboretum 



in the spring of 1909. The species was described from 



the Abbe David's specimens by the late Mr. Franchet 
R. moupinense. It is a very distinct plant readily 
recognised in the section with glandular leaves by the 
subverticelled somewhat cordate leaves, the large leafy 
calyx, the black-pilose twigs and petioles, the large 
white corollas spotted with red within the posterior side 
of the tube, and by the large conspicuous carmine 
anthers. The species is of sturdy dense habit, and as 
young plants speedily reach the flowering stage, blossom- 
ing for the first time when three or four years old and 
only a few inches in height, it is admirably adapted for 
the Rock Garden. According to Wilson it reaches a 
height of two to four feet and is usually found growing 
upon evergreen oaks and other broad-leaved trees. But 
in spite of its epiphytic character it appears to thrive 
very well in the sandy peat in which rhododendrons as a 
whole do so well. It has hitherto flowered in February 
and March, a date so early as to render the blossoms 
liable to injury bv frost.

The member of the Myrtle family which is liore de- 
picted is a species which was already figured in this 
work, at t. 473, more than a century ago. This species, 
Eugenia uniflora, is a native of Brazil and other parts of 
tropical America, but there are few tropical regions in 
which it is not cultivated, while in many it has become 
naturalised and established as a denizen in the vegetation. 
The specimen on which Linnaeus originally based his 
diagnosis came as a matter of fact from India; This 
may help to account for the fact that when he had to 
deal with a specimen of the same plant from a country 
of which it is really a native the illustrious Swede re- 
named it Plinia pedunculata, under which synonym it 
was described in these pages in 1700. We have not, 

February, 1915. 



however, taken the unusual course of supplying a second 
portrait of the same species owing to the fact that in the 
previous instance it was alluded to under an unnecessary 
name, but because in 1799 the fruit, which is not always 
to be met with in cultivated specimens, could not then 
be illustrated. The plant from which the material for 
our plate has been derived is one which was presented to 
Kew by the Director of the Jardin Colonial, Paris, under 
the name E. Michelii, Lamk. It has been grown in the 
great Palm House in a pot and has formed a much- 
branched shrub, some seven feet in height. There it 
fruited freely in May, 1914, and has enabled us to supple- 
ment the original plate. The fruits are edible. The 
specimen now figured, like that figured in 1799, is typical 
of the species, which, however, exhibits a certain degree 
of variation in the disposition of the flowers. 

Description.— Shrub or small tree; twigs terete and 
glabrous, internodes about as long as the leaves. Leaves 
opposite, ovate - elliptic, with an obtusely acuminate 
apex and a rounded base, up to 2± in. long and 1J in.

veins raised, on the upper midrib slightly impressed, but 
the nerves and smaller veins slightly raised; lateral 
nerves numerous on each side of the midrib, anastomos- 
ing towards the entire margin; lamina glabrous and 
punctate, supported by a petiole which is up to £ in. 
long. Flowers solitary, axillarv, usually distant;

The very striking Orchid of which a figure is here 
given was first imported to England from New Guinea 
by Messrs. Hugh Low and Company, Enfield, and at 
once attracted attention. Its long pendulous leaves 
with a glaucous upper surface suggested comparison 
with the genus P halaenopsis , owing to the resemblance 
thev bore to those of P. SchiUeriana ; at the same 
time the pseudobulbs indicated affinity with the genus 
Bulbophyllum. In May, 1914, a plant in the possession ot 
Mr. E. V. Low, Vale Bridge Nursery, Hayward s Heath, 
produced an inflorescence. This plant later became the 
property of the Rev. J. C. B. Fletcher Mundham 
Vicarage, Colchester, by whom it was exhibited at a 
meeting of the Royal Horticultural Society under the 
name Bulbophyllum Fletcherianwn. From a water coioui 

sketch of the plant and a single flower presented to ive* 



March 



by Mr. Fletcher, supplemented by the use of a living 
plant kindly lent for the purpose by Messrs. Stuart Low 
and Company, Jarvisbrook, Sussex, it has been possible 
to prepare the accompanying plate. The species is 
not a Bulbophyllum, if that name be employed in its 
proper and more restricted sense, but a Cirrhopetalum. 
Its affinity is not very clear, but it bears a rather remote 
resemblance to another New Guinea species, which has 
been figured at t. 7557 of this work as C. robustum, Rolf e, 
which has, however, much smaller green leaves and 
much smaller flowers. The leaf in the background of 
our plate is a portrait of one of the leaves on 
Mr. Fletcher's plant; the largest of the leaves on that 
plant, it may be added, was fourteen inches long. The 
smaller plant, shown entire on our plate, is that in the 
possession of Messrs. Stuart Low and Company. It has 
been propagated from a small side growth and as yet is 
far from being fully developed. The cultivation suitable 
for other species of Bulbophyllum and Cirrhopetalum has 
been found appropriate for this species.

The Choniastrum section of the genus Rhododendron 
includes a small and fairly compact group of seven species 
distinguished from their congeners by the position of the 
flowers, which are produced from axillary buds crowded 
at the ends of the branches. This character is always 
associated with eglandular persistent leaves and long 
tubular funnel-shaped corollas; even the seed-pods in 
this group have a facies of their own. Within the 
Choniastrum group the subject of our illustration, 

March, 1915. 



It. stamineum, differs from its allies in having strikingly 
long, far-exserted stamens. A native of Western China, 
where it was met with by Mr. E. H. Wilson in 1900 
when collecting on behalf of Messrs. J. Veitch and Sons, 
it affects particularly rocky shady ravines ; although 
widely spread in that region, it is, according to Mr. 
Wilson, nowhere really common. For the material from 
which the accompanying plate has been prepared we are 
indebted to Mr. J. C. Williams, Caerhays Castle, Gorran, 
Cornwall, in whose renowned collection it flowered in 
April, 1914. The plant by which that material was 
provided grows, Mr. Williams informs us, on a steep 
hillside which faces east, but is well sheltered on all 
sides from the wind, with no shade save what is afforded 
by the contour of the locality, and fully exposed to 
whatever of sun its side of the hill receives. This plant, 
which was obtained by Mr. Williams from Messrs. Veitch 
in 1903 and is now nearly six feet in height and some 
five feet through near the ground, has borne stray 
flowers for three years and is now, in 1915, covered with 
bud. At Caerhays R. stamineum has been tried in other 
aspects, and the most vigorous individual plant in the 
collection there is in partial shade on a hillside which 
faces rather to the north of east. But while this 
example of R. stamineum forms a beautiful evergreen 
with a fine black-green foliage and young growths of a 
charming bronze colour, it has not yet, although thirteen 
years old, produced any flowers. Mr. Williams remarks 
•that in his experience the sun kills more plants at 
Caerhays than does the frost, though the wind is always 
the worst enemy, and that if only the wind can be kept 
out, a hillside which faces east or north-east is preferable 
for most of the Rhododendrons. From the experience 
in other collections it would appear that R. stamineum is 
not an easy plant to keep in vigorous health or to flower 
freely. When success attends the effort, the pains 
expended are well recompensed whether for the charm 
of the form or the fragrance of the flowers. At Caerhays 
it is propagated by means of layering. 

Description.— Shrub ; twigs subterete, about J in. 

thick ; bark glabrous, pale brown. Leaves ovate-lanceo- 



late, gradually bluntly acuminate, base rounded, margin 
cartilaginous, 2-4 in. long, §-l| in. wide, firmly leathery,

The interesting Butterwort here figured is a native of 
Mexico, where it was first discovered by Dr. Purpus in 
1910 growing on wet gypsum rocks at Minas cie ban 
Rafael in the State of San Luis Potosi. The plant from 
which our plate has been prepared was purchased m 
1912 from Mr. R. Graessner of Perleberg. Besides being 
of pleasing aspect Pinguicula gypskoh is remarkable on 
account of the heteromorphy of its leaves. Those 



present at the time of flowering are, as depict ed 



figure, long-linear with widened base and when 



young, involute tips, and are two inches

summer- to the 



the leaves of which resemble those of some species of 
Sempervivum. When finally the linear leaves have wholly 
disappeared there is left only a compact rosette, some 
three-quarters of an inch through, such as is shown in 
fig. 5 of our plate, composed of winter-leaves one-third 
of an inch long. After persisting for a time these winter- 
rosettes behave exactly like the summer ones ; their com- 
ponent leaves gradually die off centripetally while a new 
long-leaved flowering rosette gradually forms. So different 
in appearance are these rosettes that when seen apart 
no connection between them is suggested. The hairs of 
the summer-leaves are all many-celled and gland-tipped ; 
those of the winter-leaves vary, the cilia from the base 
upwards to near the tip being unicellular and eglandular, 
while at the tip the indumentum consists of many-celled 
hairs ending in minute glands. The transition from the 
„ . ,. winter-rosette is fairly abrupt, and is 

well indicated in fig. 7 of our plate. Still more abrupt, 
however, is the passage from the winter- to the summer- 
rosette. Summer-rosettes, before passing into the winter- 
stage branch, though rather sparingly ; these branches 
develop into daughter-rosettes of the winter-stage which 
maybe detached and thus afford a means of pro x _ fe _ Ai . 
The plant apparently does not depend entirely "upon "a 
gypsum substratum ; at Kew it has thriven well and 
flowered freely in July, when grown in sphagnum moss 
kept saturated with water. Like many other species of 
finquKula, P. gi/p.^cola has shown considerable variation 
in the size of the flower. At Kew the corolla-lobes have 
been nearly half-an-inch long ; in the specimens described 
by Mr. Brandegee the corolla-lobes were about half that 
ength. At Kew it has been found possible to r«,i 6 
hybrids between P. cjypsicola and P. caudata, Schlecht., 
another Mexican species.

The subgenus Pedrosia, Brand, is readily distinguished 
from the rest of the genus Lotus, Linn., by the presence 
of a distinct tooth below the apex of the style. The 
distribution of the subgenus is circumscribed ; that of 
the species /.. campylocladus, a form of which is here 
figured, is of the " Atlantic " type, for it is confined to 
the Atlantic Islands, the Iberian Peninsula and Morocco. 

March, 191a. 



The specimens on which L. campy loclad as was originally 
based were gathered near Guimar in Tenerife, and differ 
from the form of the species now depicted in the smaller, 
more obovate leaflets and the shorter subappressed indu- 
mentum. The form villosior, here described, was originally 
met with by the late Mr. P. Barker Webb at Euencaliente 
in the south of Palm a, and was identified by him as L. 
arenarius, Brot., though with an indication that he had 
long felt a doubt as to whether the Tenerife and the 
Palma plants should not be treated as varieties of one 
species. Specimens which have since been gathered at 
Guimar and elsewhere in Tenerife have shown how well- 
founded was the doubt thus expressed ; it is found that 
these specimens form a connecting series within which it 
is impossible to distinguish even varieties. At the same 
time L. campy locladus is undoubtedly closely allied to i>. 
arenarius, within which the form now figured was included 
by Webb ; the best distinguishing mark is to be found in 
the more or less cuneate leaflets, retuse or sub truncate at 
the apex, which characterise the former. The form here 
termed villosior is widely distributed both in Tenerife 
and in Palma. In the latter island it was met with by 
Mr. Sprague and Mr. Hutchinson in the Gran Caldera 
in 1913. The plant from which our figure has been 
made was raised at Kew from seeds presented by 
Dr. G. V. Perez of Orotava. It is possible that the 
seed came in the first instance from Tenerife, for it 
appears that Dr. Perez received it under the name 
7>. mascaensis, Burchard, a species known only from 
Tenerife. At Kew the species has been tried out of 
doors but does not give promise of being hardy. When 
grown in a frame it forms a plant about a foot in height, 
compact in habit and pleasing both in its flowers and in 
its silvery foliage. 



Description.— lkrh ; root woody, branching from the 
base, with branching ascending stems woody below and 
shortly rather densely clothed with spreading hairs, as 
are the leaves and the calyces ; internodes in cultivated 
plants \-\ in. long, in wild specimens up to 2 in. long.

The striking Thunbergia which forms the subject of our 
illustration is a native of tropical East Africa. The 
specimens on which the species, T. Gibsonii, was based 
are in the national collection at the British Museum, 
Cromwell Road, where they were received from a 
locality on the equator, approximately 36° 70' east of 
the meridian of Greenwich, at an elevation of about 
8000 feet above sea-level. Both as regards the corolla 
and bracteoles these original specimens, which consist of 

April, 1915. 



flowers only, are rather larger than is the case in the 
plant from which our figure has been prepared, but there 
is no other difference discernible. The plant figured, 
which flowered at Kew in June, 1914, was acquired by 
purchase from Messrs. Thompson and Charman, Nursery- 
men, Bushey, according to whom it had been obtained 
from British East Africa from a locality 6000 feet above 
sea-level. The introduction appears to have been effected 
by Mr. W. van der Weyer, Corf e Castle, Dorset, by whom 
it was shown at an exhibition of the Royal Horticultural 
Society in May, 1913. The limb of the corolla is of a 
deep orange colour and waxy consistence, and the species 
is thereby readily distinguished from its nearest ally in 
the genus, the well-known T. alata, Boj., also originally 
a native of Tropical Africa, though now naturalised in 
some parts of South-eastern Asia, long ago figured at 
t. 2591 of this work. In habit a perennial, T, Gibsonii 
when grown in a pot under ordinary greenhouse con- 
ditions quickly develops leafy shoots which flower freely 
in summer. 



Description. — Herb, perennial, twining, 4-5 ft. high ; 
stems terete, beset with long spreading or slightly recurved 
hairs. Leaves ovate, acute, base cordate-sagittate, up to

The Chinese Rhododendron of which a figure is here 
given is one of the fruits of Mr. E. H. Wilson's expedition 
of 1903-4, on behalf of Messrs. J. Veitch and Sons, the 
plant from which our illustration has been taken being 
one raised by them at Coombe Wood and acquired Irom 
them for Kew in 1908. During his later expeditions in 
China, Wilson again met with the species on several 
occasions. It is plentiful in the neighbourhood ot 
Tachien-lu, in Western Szechuan. The nearest ally ot 
M. Davidsonianum is, perhaps, R. ambifjuttm, hems. ., 
another Chinese species figured at t. 8400 of this work. 

April, 1915. 



It is most readily distinguished from the latter species 
by the more elegant habit, the smaller leaves, the 
differently coloured flowers and the more slender fila- 
ments. Like most of the Rhododendrons from China 
with scaly leaves, R. Davidsonianum gives promise of 
being very hardy. Its value as a garden plant will 
probably be similar to that of R. yunnanense , Franch., a 
Chinese species figured at t. 7614 of this work, and like 
that species it can be increased by means of late summer 
cuttings.

cate, terete, brown or greyish, glabrous; young twigs

The section Candelabra, which owes its name to the 
type of inflorescence, is one of the most natural m the 
ranus Primula. Its members are natives of eastern and 
south-eastern Asia ; all of them appear to mhabit moist 
meadows, all produce rosettes of leaves which reca 
those of the Primrose, and all produce tall scapes with 
superposed tiers of flowers. All further agree in having 
a rounded or shortly oblong capsule enclosed in a slightly 
accrescent calyx. Within the section the species assort 
themselves in two groups, that in which the flowers arp

purple, and that in which the flowers are yellow. In 
China, where the section has its headquarters, the number 
of species belonging to either group cannot yet be safely 
estimated; of those in cultivation the best known 
members of the group with yellow flowers are P. Cock- 
burniana, Hemsl., P. Bullet/ana, Forrest, and P. serrati- 
folia, Franch. ; the most familiar among those with purple 
flowers are P. Beesiana, Forrest, P. Poissoni, Franch., and 
P. pulveridenta, Duthie. . The known species with yellow 
flowers which occur outside China are P. imperially 
Jungh., a native of Java which has the further interest 
attaching to most southern Asiatic species of the genus ; 
P.prolifWa, Wall., which occurs in the Khasia Hills, east 
of the Brahmaputra valley ; and P. Smithiana, Craib, a 
native of Sikkim in the Eastern Himalaya. The extra- 
Chinese species with purple flowers so far known are 
P. jajxmica, A. Gray, which is restricted to Japan ; and 
the subject of our illustration, P. Miyabedna, which is 
endemic m Formosa, and is readily distinguished from 
all the other known members of the section Candelabra in 
having the calyx farinose within. The plant figured is 
one which was raised from seed received at Kew in 1913 
from Mr. W. R. Price, who met with the species on 
Mount Morrison in Formosa, growing at an elevation of 
7000 feet above sea-level. The plant has been cultivated 
at Kew in a frame, where it flowered in May, 1914, and 
ripened its seeds in July. It may prove to be hardy, at 
least in the warmer districts of the British Islands. It 
will probably be best to treat it as a biennial under the 
conditions given to its near ally P. Poissmi, figured at 
t. 7216 of this work, like which it behaves under culti- 
vation. A marked feature of the members of the section 
Candelabra is the readiness with which several of them 
lend themselves to hybridisation.

The Araliad here figured was originally described by- 
Professor Oliver from specimens discovered by Professor 
A. Henry in the province of Hupeh in Central China 
about 1886. It was met with again in the same region 
by Mr. E. H. Wilson in 1901, and through his agency 
was introduced to cultivation by Messrs. J. Veitch and 
Sons. The plant which has supplied the material for our 
illustration is one at Kew which was purchased from 
Messrs. Veitch in 1913. When first described the species 
was referred with justice to the genus EUutherococcu*, 
based by the late Mr. Maximowicz on a species from 

April, 191a.

proved satisfactorily that this genus is not in reality 
separable from the older genus Acanthopanax. In gardens 
A. leucorrhizum, here depicted, has been confused with 
A. Simonii, C. K. Schneid. ; the figure which was pub- 
lished in the Gardeners' Chronicle on 9 December, 1905 
(fig. 152), under the name Eleutherococcus leucorrhizus is 
not the plant now described, but is really A. Simonii. 
The plant there referred to is well distinguished from the 
true A. leucorrhizum by its much stouter hooked spines 
distributed irregularly on the branchlets and by the 
numerous bristles on both surfaces of the leaflets. Another 
species very closely allied to the subject of our plate 
is A. Henryi, Harms, already described at t. 8316 of this 
work, which differs from A. leucorrlrizum m.h.&Ymg shorter, 
stouter spines, shorter pubescent pedicels and pubescent 
leaves. The bark of the roots of A. leucorrhizum, from 
the appearance of which the specific name has been 
derived, is stated by Henry to be used by the Chinese 
as a drug, known to them as the White " Wu Chia P'i. 



As a shrub for gardens, A. leucorrhizum will be valued 



»5 



chiefly for its handsome foliage, of a type uncommon 
among hardy shrubs, and for its striking umbels of 
purple-black berries which are produced very abundantly 
and remain on the bushes late into the autumn. It has 
withstood perfectly the frosts experienced since its 
introduction, and although these have not provided the 
hardest tests of our climate we may reasonably assume 
it to be hardy. It thrives in well-drained sandy loam 
and is easily propagated by seeds. 

Description. — Shrub, 6-10 ft. high, everywhere glab- 
rous ; branchlets very pithy, sprinkled with pale lenticels, 
armed at the nodes with 1-6 pale, decurved spines J~|

The Iris here figured was discovered by Professor J. K. 
Urumov at Eski Dzumaja in Bulgaria in 1901. In his 
monograph it was referred by Mr. W. R. Dykes to I. Sin- 
tenisii, Janka, but, on raising plants from seeds obtained 
from Messrs. Vilmorin, Mr. Dykes recognised it as distinct. 
This decision has been confirmed by a plant received by 
the Hon. N. C. Rothschild from the original locality in 
Bulgaria. The difficulty experienced has been due to 
the original description. Dr. Velenovsky has described 
the plant as having green leaves and greenish spathes, but 
these organs, as Mr. Dykes points out, are glaucous, this 
colour being enhanced by the fairly large white asperities 
on the nerves. The dimensions here given have been

derived from the specimen, sent by Mr. Dykes, which has 
served for our plate. But the stems may attain a height 
of 6-10 inches, while the leaves may be 18 inches long 
and a quarter of an inch wide, and the spathes may be 
over 4 inches in length. On the other hand Velenovsky's 
plants had leaves one-twelfth of an inch across or under, 
while according to him the falls may measure as much as 
an inch and a half in length by an eighth to a sixth of 
an inch in width. Mr. Dykes finds that this species is as 
easy to grow in his garden at Godalming as the well- 
known 7. graminea. It loses its foliage in the autumn, 
and it is not until the end of January that the glaucous 
tips of the leaves appear. It is not fastidious as to soil 
and has done well in sand enriched with leaf mould and 
chalk, but Mr. Dykes believes that it might grow even 
better in a stiffer loam overlying chalk. It should be 
moved, if necessary, either immediately the flowers are 
over or when growth becomes active in spring, but not 
in the autumn when the plant is dormant. 

Description.— Herb, rootstock brown, oblique, hardly 
as thick as a little finger. Stems several, 4-5 in. high, from 
almost to quite enveloped by the leaves, their bases sur- 
rounded by the dry remains of the old foliage. Leaves 5-6 
to a stem, at flowering time barely reaching the blossoms, 
thereafter elongating and at length 10 in. long, \-l in. wide 



linear, acute or very acute, glaucous, laxly nerved, the 
nerves rough with rather large white papillae. Spathes

The fine Gentian here figured belongs to a group of 
forms for which it is hard to find limiting characters, 
and there is a fairly complete series of forms transitional 
between small northern examples of Gentiana detonsa f 
Rottb., a species to which our plant is closely allied and 
within which it is at times included, and the form with 
large and beautiful flowers represented in our illustration* 
The plant originally described as G. detonsa from speci- 
mens obtained in Norway and perhaps also in Iceland 
is characterised by its quadritid corolla with crenulate 
lobes neither barbate nor fimbriate on the margin below 
the middle, as well as by having erect stems. The plant 
which Froelich first described as G. barbata is usually 
considerably larger than typical G. detonsa, with which it 
agrees in its quadrifid corolla. It is a native of Siberia 
and the Caucasus, and in spite of general agreement 
with G. detonsa is readily distinguished by its often

ascending but not strictly erect stem, by its more acute 
or acuminate leaves, and especially by the corolla lobes, 
which are fimbriate on the margin just below the middle. 
This typical condition of G. barbata has already been 
figured at t. 639 of this work as G. ciliata, which name, 
however, belongs to another species. The form now 
figured differs from typical G. harbata chiefly in having a 
larger corolla and longer, more acuminate sepals. The 
plant figured was raised from seed received from the 
Royal Botanic Garden, Edinburgh, in 1912,and flowered 
at Kew in September, 1914. This form is hardy and has 
behaved as a biennial, all the plants having died soon 
after flowering ; a few seeds, however, were ripened. 
It thrives well in ordinary garden soil and prefers partial 
shade. 



Description. — Herb, annual, almost erect or more 
often ascending; stems simple or somewhat branched, 
terete, 2-sulcate, glabrous. Leaves linear-lanceolate, 
acute or acuminate, up to 2\ in. long, over ^ in. wide, 
midrib impressed above, raised beneath, the lateral 
nerves hardly visible on either surface, glabrous, sessile. 
Flowers solitary ; peduncle sub terete, glabrous, up to 
4 in. long. Calyx green, glabrous, 2-2| in. long ; lobes

The very interesting Zygopetalum which is the subject 
of our plate is one of the Peruvian discoveries of 
Mr. L. Forget when collecting in South America on 
behalf of Messrs. F. Sander and Sons. The plant flowered 
for the first time in their collection at St. Albans in 
September, 1914, and was then purchased from them for 
Kew. Its nearest ally appears to be Z. Burkei, Reichb. f., 
a native of Mount Roraima in British Guiana, the two 
species being extremely like each other as regards the 
shape of the labellum. They are, however, readily 
distinguished by their pseudobulbs and leaves which 
are considerably larger in the Peruvian than in the 
Guiana plant. They also differ as regards the colour of 
their flowers, there being fewer green markings on the 
petals of the species here described. The treatment 
suitable for the stronger species of Zygopetalum, such as 
Z. crinitum or Z. intermedium, is found to be well 
adapted to the needs of Z. Prainianum also.

Introduced originally by David Douglas from Western 
North America about 1826, Amelanchier florida has pro- 
bably been in cultivation during most of the period that 
has elapsed since then, although latterly it has been con- 
founded with A. alnifolia, Nutt., both in gardens and in 
botanical works. Growing together, as these two species

The Primula now figured is a native of the western 
districts of Szechuan in South-west China. It was first 
met with in 1890 in the neighbourhood of Ta-tsien-lu by 
Prince Henri d' Orleans and his companion Mr. Bonvalot, 
and was originally described from their specimens by 
Professor Bureau and the late Mr. Franchet. It was 
met with again in the same neighbourhood in 1908 by 
Mr. E. H. Wilson when collecting on behalf of Messrs. 
J. Veitch and Sons, and was introduced to horticulture 
by them from seeds received from Wilson. The plant 
from which our plate has been prepared was presented 
to Kew bv Messrs. Veitch in 1912, and flowered in the 
Alpine Collection in 1913. As a species P. pycnoloba

stands in marked contrast to many of the forms, and 
more especially to those whose home is in Western and 
Southern China, which have been recognised within the 
genus Primula, in exhibiting characters which admit of 
its unqualified recognition. But if there is in this case 
no question as to the claim of our plant to specific rank 
its position within the genus has been the subject of 
some debate. Professor Pax and his fellow-worker 
Dr. Knuth have treated it as a member of the section 
which includes the familiar P. sinensis, Sabine, already 
figured in this work. Professor Bayley Balfour, how- 
ever m his more recent scholarly study of the Chinese 
members of this difficult genus has advanced good 
reasons for the view that the Sinenses of Pax and 
Knuth should be regarded rather as an aggregate of 
natural groups or sections, of one of which, the section 
lycnoLoba, the species now described is the type and 
the sole representative. P. pycnoloba thrives well under 
ordinary alpine treatment in a shaded portion of the 
Kock Garden, and so far has not been injured by cold 
at Kew. It can also be successfully grown in pots in 
a cold frame. At Edinburgh, Professor Balfour states, 
it is easily grown if protected from overhead moisture 
when resting; it spreads rapidly in the soil by means 
of its root-buds, which afford a ready means of propa- 
gation It may be remarked here that the plant now 
figured suggests that it represents an unusually vigorous 
strain; at all events it has more numerous flowers and 
rather broader calyx-lobes.

The Birthwort which is the subject of our illustration 
was first described by the late Dr. Maxwell Masters from 
herbarium specimens collected by Mr. Appun in British 
Guiana. It was alluded to again by Masters in the 
Gardeners' Chronicle in 1890, his note being accompanied 
by a figure based on a plant introduced from Demerara 
and flowered at North Cray by Mr. Todd. The present 
figure has been prepared from a plant presented to 
Kew in June, 1913, by the Rev. A. Miles-Moss who 
had met with this and several other species of Aristo- 
lochia in the State of Para, Brazil. This plant has 
thriven well in a moist tropical house. It flowered for 
the first time in February, 1914, when its identity with 
the Guiana plant described by Masters as A. longeo tutl tta 
was established. Among the especial characters noted 
by Masters as characteristic of the species is the dense 
patch of hairs in the perianth throat. Another notable, 
though in the genus Aristolochia rather general feature 
is the powerful and disagreeable odour of the flowers in 

June, 1915. 



our plant, which it ought to be remarked must not be 
confused with the very different A. loncjecaudata from 
Mexico described by Dr. Sereno Watson, which Dr. Rose 
has more recently renamed A. Pringlei. Already two 
Birthworts with elongated perianth-lobes have been 
described in this work. One of these was figured at 
t. 2545 as A. labiosa, Ker-Gawl. ; this species, which has 
the lobe widened and 2-lobulate at the end and of a 
paler ground-colour, was also figured as A. ci/mbifera, 
Mart. & Zucc, which is the correct name, in the Botanical 
Register at 1. 1543. The other species with an elongated 
lobe already figured here is A. grandiflora, Vahl, described 
at t. 4369 ; in this plant the basal portion of the lobe is 
suborbicular, above the base it is suddenly contracted 
into a long tail. The species to which A. longecaudata is 
most closely allied is A. Leprieurii, Duchartre, which 
differs in having the inflated portion of the perianth 
straight. 

Description.—^^, perennial. Stem scandent, spar- 
ingly shortly hirsute. Leaves entire or lobed, more or 
less ovate or oblong, acute or acuminate, base cordate,

The Hippeastrum of which a plate is given here was 
discovered by Mr. H. J. Elwes in 1902 near Lake Nahuel- 
Huapi on the Rio Limay in Argentina. The upper 
reaches of this river, where //. Elwesii grows, arc in a high 
dry valley with a cold winter climate and witli a vegeta- 
tion quite different from that met with at similar alti- 
tudes on the Chilian side of the Andes. A plant brought 
to England by Mr. Elwes flowered in his garden at 
Colesbornc in September, 1903, and the scape then pro- 
duced forms the main part of the present figure. The 
plant flowered again in September, 1914, and from 
material then supplied the plate was completed. In 
the genus Hippeastrum, H. Elwesii seems very distinct 
in the ultimately spreading perianth-lobes. It is 
perhaps most nearly allied to II. Ananuca, Phil., originally 
described from specimens collected at Caldera in the 
province of Atacama, but is readily distinguished from 
that species by its uniformly pale yellow perianth-lobes 
with the tube claret-coloured inside; in //. Ananuca the 
lobes though yellow elsewhere have vivid red midribs. 

June, 1915. 



The prolonged interval between the first and second 
flowering of this plant at Colesborne testifies to the diffi- 



experienced in providing suitable conditions. This 



difficulty, Mr. Elwes points out, it shares with antipodean 
bulbs generally, and resides in their unwillingness to 
change their season of growth. The beautiful terrestrial 
orchids secured by Mr. Elwes during the journey of 
1902 it has been impossible to preserve, and even in 
those instances in which species like Tecophilaea ci/ano- 
crocus, Mppeastrum pratense, Alstromeria Jlookeri have 
survived, it has been necessary to afford frame protection. 
Even when raised from seed ripened in this country the 
plants of Alstromeria do not readily change their season, 
but continue in growth throughout the winter. Doubt- 
less it is largely owing to this intractability that com- 
paratively few of the beautiful bulbous plants from the 
Andes of Chile and Northern Patagonia are to be found 



English gardens, and it would be well if those who 
have correspondents resident there could induce these to 
send plants or seeds to this country and to repeat their 
introductions from time to time until the difficulty to 
which Mr. Elwes refers has been at last overcome.

The genus to which the striking and brilliantly coloured 
parasite now depicted belongs was discovered by Tourne- 



fort in Armenia in 1701, and dedicated by him to the 
family of the distinguished Chancellor of France, Louis 
Phelipeaux, Count of Pontchartrain who, as the Secre- 
tary of State in charge of the Academies, moved his 
Sovereign in 1699 to send Tournefort to the Levant. 

June, 1915. 



m 



far 



Unfortunately Tournefort added to his genus a yellow- 
flowered Iberian species of Clstanche. This misappre- 
hension might have been of small account had not 
Linnaeus, half a century later, placed Tournefort's genus 
in Lathrdea, as L. Phaelypaea, including in his species so 
named both the Phelipaea and the Clstanche, and, to make 

rse, treating the red-flowered Phelipaea as a 
mere variety of the yellow-flowered Cistanche. The 
extraordinary degree of confusion which resulted from 
this treatment it took nearly a century and a half to 
clear up ; the story has been lucidly told by Dr. Stapf 
in the Kew Bulletin for 1915. In the meantime it is 
sufficient to remark that the name Arwplanthus which 
has been used for this genus is a needless innovation and 

as is known, there are but three species of 
Iltelipaea, the species discovered by Tournefort, which 
Desfontaines named P. Toumefortii; the subject of our 
plate, which Lambert named P. foliata; and a third 
species, P. Boissieri, a description of which is to be found 
in Dr. Stapf's article in the Kew Bulletin. The original 
species has been repeatedly collected in Armenia°and 
occurs also in Kurdistan. The one now figured was first 
met with near Tiflis by Giildenstedt and in the northern 
foothills of the Caucasus and in Daghestan and Shirwan 
by Marshal von Bieberstein. It has since been collected 
in various localities on both sides of the Caucasus and in 
the southern Crimea. The area of the genus extends to 
JNortn Syria, through Southern Asia Minor as far as 
Caria and eastwards to Tabriz. The host-plant of 
P. Johata, so far as is known, is always Centaur ea dealbata ; 
I. 1 ournefortn has been collected as a parasite affecting 

± yrethrum myriophyllum. fe 

The plants on which our figure has been based 
were grown at Kew from seeds received from the 
Botanic Garden, Tiflis, in 1911. In this case the host- 
plant was Lentaurea dealbata. The seeds of host and 
parasite were sown together in a pot, but only the 
Centaurea came up. Later in 1911 the Centaurea 
planted in the Rock Garden, where it grew alone u 
in May, 1914, seven stems of the Phelipaea, each bearing 
a solitary flower-bud, made their appearance, the first 
bud to open doing so in the middle of the month. It is 



was 



; 



interesting to recollect that a very similar experience has 
been recorded in Gartenflora for 1880 on the part of the 
Imperial Botanic Garden, Petrograd. There, in June, 
1879, after a corresponding interval, plants of P. foliata 
made their appearance in association with a Centaurea. 
The difference in this case is that roots, not seeds, of the 
host, which had come from the Caucasus, were planted 
in the first instance. The combination of the bright 
scarlet flowers of the parasite with the silvery grey 
foliage of the host is singularly attractive, and one 
marked feature of the partnership in the Kew case has 
been that the health of the host, so far as may be judged 
by its appearance, has remained unimpaired. 

Description.—//^^, parasitic, leafless. Stems simple, 
rather stout, glandular-puberulous especially in the upper 
half, reddish, 1-1 £ ft. high. Scales ovate-oblong, obtuse, 
stem-clasping, scattered on the lower half of the stem 
and fairly wide apart, papillose-puberulous or glabrous. 
Flower solitary, terminal, ebracteate. Calyx campanu- 
late, f-lj in. long, unequally 5-lobed, usually somewhat 
2-lipped and more deeply divided between the 3 upper 
approximate lobes and the two lower; lobes oblong or 
ovate, obtuse, more or less glandular-papillose through- 
out, or glabrescent upwards, deep-red or chestnut-brown. 
Corolla ringent ; tube widely and obliquely campanulate, 
at length incurved, f-1 in. long, orange flushed with red 
outside, and sparingly papillose upwards, pilose in the 
front of the throat down to the attachment of the 
filaments; limb 2-lipped, lobes of each lip subequal, 
rounded, those of the upper rather smaller than those 
of the lower, J-J in. across, reddish-yellow outside,,

The interesting Dorstenia which we figure here is a 
native of the Belgian Congo, in some districts of which 
territory it is plentiful. For its introduction to cultiva- 
tion we are indebted to the efforts of the Director of the 
Botanic Garden at Eala in the Equatorial Province, 
whence living plants appear to have reached the Colonial 
Garden at Laeken near Brussels about the year 1907. 
It first became known to English horticulture in October, 
1910, when a plant was exhibited at a meeting of the 
Royal Horticultural Society by Messrs. J. Veitch and 
Sons on behalf of the Director of the Royal Botanic 
Garden at Brussels. This plant was thereafter presented 
to the Royal Gardens at Kew, and forms the subject of 
our illustration. D. yamhuyaensis is a plant of erect 
habit and produces its flowers at the tips of slender 
axillary peduncles when it is about a foot and a half 
high. As an addition to our tropical greenhouses this 
species is remarkable for the much elongated pinnatisect 
processes of the receptacle, a character which at the 
same time readily distinguishes it from its congeners.

For the introduction to cultivation of the striking 
Echium which forms the subject of our plate, horticulture 
is indebted to Dr. G. V. Perez of Tenerife, from whom 
seeds were received at Kew in 1911. These seeds were 
sown in heat in the following spring, and two years 
later the plants raised came into flower in the Temperate 
House, when they were recognised by Mr. Sprague, who 
has made an exhaustive study of the genus Echium, as 
belonging to a hitherto uncharacterised species, nearly 
allied to E. Wildpretii, figured at t. 7847 of this work. 
The illustration here given represents one of these 
plants. The plant now figured resembles./?. Wildpretii 
in its foliage except in that the leaves are decurrent 
to the base ; it further differs bv its lax thyrse and 
m having longer style-arms. The species has been 
named in honour of the discoverer, who has done so 
much for the cause of botany in the Canaries, and is 
himself an ardent student of the genus to which it 

July, 1015. 



belongs. E. Perezii, the plant now described, is confined 
to the Island of Palma, one of the western members of 
the Canary Group, where it was first met with a few 
years ago near Punta Liana. Its ally E. Wildpretii on 
the other hand is a native of Tenerife. There is a 
difference possibly of minor importance in the colour of 
their corollas, that of E. Wildpretii being pale red, 
whereas that of our plant is pale pink. The most 
striking difference is in their general habit. This will be 
best appreciated by an examination of photographs of 
the two published in the Kew Bulletin for 1914 at 
pp. 266, 267. The treatment most suitable for both is 
pot-cultivation in a light loamy compost in a sunny 
greenhouse. The plants of E. Perez ii when they came 
into flower were in eight-inch pots. 

Description.— Herb, tall and erect. Stem in the plant 
figured about 2 ft. high, in those grown in the Canaries 
over 6 ft. in height, simple, losing its leaves at the base, 
elsewhere densely leafy. Leaves above the base deflexed, 
narrowly linear-lanceolate, about 5 in. long, J-J in. wide, 
caudate-acuminate, gradually narrowed to the base, 
rather coarsely silky; lateral nerves about 4 on each 
side, somewhat oblique, hardly visible or slightly sunk 



above, raised beneath ; upper leaves similar but ascend 
ing. Thyrse terminal, ovoid, many-flowered, about 10 in. 
long and 5 in. across ; cymes scorpioid, very markedly 
pedunculate, about 3 in. long, including the j~l£ in. long 
peduncles; lower and intermediate cymes 2-furcate, 
about 25-flowered, upper cymes simple; peduncles and

The interesting orchid which forms the subject of our 
illustration was originally discovered in Sierra Leone by 
Afzelius and was described by Swartz from this material 
as Dendrobium paniculata?)!. Its identity had long been 
doubtful, but was definitely settled owing to the kindness 
of Professor Fries of Upsala by whom the type of the 
species was lent to Sir W. T. Thiselton-Dyer while the 
Orchidaceae of Tropical Africa were being described. 
When the species was transferred to its true genus, 
Polystachya, in 1897, it was still known only from the 
Afzelian specimens, but a few years later a good 
herbarium specimen was transmitted to Kew by Mr. C. B. 
Ussher, who had met with it again in the Mabira Forest, 
Chagwe, in the Uganda Protectorate. For its intro- 
duction to our collections orchid growers are indebted to 
the late Sir Trevor Lawrence, who had received plants 
from West Africa communicated by his son, Captain C. T. 
Lawrence. It flowered in Sir Trevor's collection at 
Burford, and was exhibited at a meeting of the Royal 

July, 1915. 



Horticultural Society in Aug 



1910. Since then it 



has found its 



ay 



into various collections and has 



flowered on several occasions. The plant from which 



figure has been made was obtained for Kew 



1910 



from Messrs. Charlesworth and Co., Hay wards Heath. 
It grows well and flowers annually at Kew in March in 
a tropical house under the treatment suitable for most 
species of Dendrobium and Epidendrum. The flowers of 
P. paniculata are borne in a dense panicle; the yellow 
sepals and petals striped with orange-red, and the reddish 
orange lip, combine in rendering it a striking object.

but the accession of 



fuller material having shown that this position for the 
plant was unsatisfactory, it was transferred to M. rudis to 



hich it is more nearlv allied 

July, 191",. 



This position in turn h 



been found untenable ; the species now figured differs 
from M. rudis in its more herbaceous foliage, its shorter 
flowering pedicels, its white in place of yellow stamens, 
and its pale green in place of yellow stigma. Its native 
country includes the Western Chinese provinces of 
Szechuan and Kansu, where it occurs at elevations of 
13-15,000 feet above sea-level. The introduction of 
i)A Prattii to European horticulture has been due almost 
equally to Mr. E. H. Wilson and Mr. F. K. Ward. The 
material on which our figure is based has been provided 
by a plant raised at the Royal Botanic Garden, Edin - 
burgh, and grown under the name M. Wardii, from seed 
collected by Mr. Ward, which was kindly communicated 
for the purpose by Professor Bayley Balfour. The species 
has proved hardy and thrives well under the conditions 
suitable for M. aculeata, M. latifolia and M. rudis.

Among the many novelties from China which have 
enriched European gardens during the past decade none 
have been more striking than the members of the genus 
Rhododendron. The illustrations of such of these as 
have been described in this work afford but an imperfect 
idea of their variety and beauty. As experience of the 

•July. I'M 5. 






Chinese forms under cultivation increases, however, 
questions of relationship and status have arisen in con- 
nection with some of them; and certain plants which 
when first communicated appeared from the descriptive 
standpoint to be easy of discrimination have been found 
in our living collections to display characteristics which 
tend to cast doubt on earlier conclusions. The species 
which forms the subject of our plate is one that gives 
rise to such an inquiry. It is one of a series of forms, 
undoubtedly very closely allied, which certainly con- 
stitute a natural group, fairly readily distinguishable 
from each other by differences in the size and colour of 
the flower and by some amount of variation in the 
development of the calyx, but which, nevertheless, in 
the opinion of Mr. Hutchinson, who has bestowed on 
them much critical study, may all be very well referred 
to a single species. So far as regards the calyx, which 
m many groups of species in the genus affords a constant 
and distinctive feature, we find in the group under con- 
sideration that it may be almost obsolete, as in the case 
of the original specimens, collected on Mount Omei in 
bzechuan by the Rev. Mr. Faber, on which R. concinnwn 
was based, and as is again the case in the plant now 
figured ; or it may be well developed with oblong-lanceo- 
late cihate lobes as in the plant described by Professor 
Bureau and Mr. Franchet as R. yantkinum. Yet except 
as regards their calyces there is no very tangible feature 
wherein R. concinnum and R. yantkinum differ, and 
having regard to the fact that in the extensive series of 
specimens, both wild and cultivated, which Mr. Hutchin- 
son has examined, there is a complete gradation between 
these two extremes, the question as to their possible 
identity calls for consideration. The fact that sometimes 
in the same truss may be found a calyx in which all or 
some of the lobes are well developed, and others in which 
all the lobes are much reduced or practically obsolete is 
strongly corroborative of Mr. Hutchinson's view. Among 
cultivated examples it is found that there is a con- 
siderable variation n the size of the corolla in plants of 
different age or under different treatment, and the same 
feature in wild specimens may be due also to difference 
ot age or to a dissimilar habitat. Variation in thn nnlnur 



of the corolla is equally manifest and appears equally 
explicable. Certain minor differences, such as the presence 
or absence of a few hairs either on the basal portion of 
the style or on the apex of the ovary, are found to be as 
inconstant as the degree of development of the calyx- 
lobes, and to be uncorrelated with the variation in size 
and colour of the corolla, and Mr. Hutchinson has felt 
constrained on this account to include in E. continuum, 
in addition to E. yanthinum, not only the form described 
by Mr. Hemsley in 1907 as E. Benthamianum, but the 
still more distinct-looking E. coombmse, figured at t. 8280 
of this work. It is to be noted that the form described 
as E. Benthamianum which is here referred to is not the 
plant so described in 1910. The latter differs from all 
the forms now included under E. continuum in having a 
conspicuously spotted corolla and a more prominent 
areolation of the upper surface of the leaf. It has also 
to be remarked that while B. coombense is not distinguish- 
able from E. concinnum here figured by any valid morpho- 
logical feature, in its typical condition these two forms will 
probably always be treated as culturally distinct. In 
any case they constitute the extreme conditions of what 
is an exceedingly variable group of forms, and whatever 
their relative status may be, the one now figured is the 
most richly coloured and the most worthy of cultivation 
in that group. The plant from which our figure has 
been prepared was presented to Kew in 1908 by Messrs. 
J. Veitch and Sons, and was raised by them at Coombe 
Wood from seed obtained on their behalf by Mr. E. H. 
Wilson during one of his earlier Chinese journeys. Like 
all the forms included within it by Mr. Hutchinson, 
that now figured was collected in the neighbourhood 
of Ta-tsien-lu, in Western Szechuan. It is perfectly 
hardy and succeeds well in a light loamy or peaty soil.

The Alpinia here figured was first described as A. mutica 
in 1810 by Roxburgh, who had obtained it from Penang, 
then known as Prince of Wales 5 Island, and cultivated it 
in the Hon. East India Company's Botanic Garden at 
Calcutta, where it flowered during the greater part of 
the year, though most profusely during the hot weather. 
Its introduction to European cultivation must have been 
almost simultaneous with its advent to India, for in 1812 



Salisbury mentioned it as having then "flowered for 
three years successively in the stove of the Comtesse 
de Vandes at Bayswater." In 1828 Roscoe referred to 
it as flowering regularly in August in the Liverpool 
Botanic Garden. At a later date it became rare in 
British collections, and seems eventually to have dis- 
appeared from cultivation, though the name survived 
and became erroneously associated with more than one 

August, 1915. 



of the congeners of our species. The one to which the 
name is at present more usually misapplied is that 
described as A. mutica at t. 6908 of this work, which, 
however, differs from the true A. mutica here depicted in 
having much stouter flower-buds, and in possessing a 
labellum which is not distinctly 3-lobed. For the detec- 
tion of the error which has crept into horticultural lists, 
and for the successful reintroduction of the true plant we 
are indebted to Mr. H. N. Eidley, by whom, while he 
was still Director of the Botanic Garden at Singapore, 
the plant from which our figure has been prepared was 
transmitted to Kew. Grown in a tropical house under 
the conditions most suitable for species of Hedyckium 
and for other species of Alpinia, such as A. nutans which 
was figured at t. 1903 of this work, it has thriven well, 
flowering for the first time in July, 1914, along with the 
species which in English collections has for a quarter of 
a century usurped its name, and enabling the difference 
between the two plants to be objectively appreciated. 
What the spurious A. mutica figured in our pages in 1889 
may be is still a matter of some debate. Mr. Ridley 
has regarded it as identical with A. assimilis, Ridl., a 
species described by him in 1899, but the late Dr. 
Schumann has treated it as a form of A. malaccmsis, 
Roscoe, a figure of which is to be found in the Botanical 
Register at t. 328. It may be incidentally mentioned 
that at one time Dr. Schumann himself applied the name 
A. mutica to yet another species from Borneo, which he 
subsequently recognised as specifically distinct under the 
name A. Korthalsii, K. Schum. The nearest affinity of 
the true A mutica, Roxb., is, as Mr. Wright has indicated, 
with ,1. calcarata, Roscoe. The two species are, however, 
very readily distinguished by their differently shaped 
Jabellum which in A. mutica has two basal hirsute glands 
instead of the spurs met with in that of A. calcarata.

The beautiful Rhododendron now figured is a native of 
the neighbourhood of Ta-ehien-lu in Western Szechuan, 
where it occurs rather abundantly in upland thickets and 
woods at about 12,000 feet above sea-level. The plant 
from which the material for our plate has been derived 
was raised from seed collected in 1908 by Mr. E. H. 
Wilson when travelling in China on behalf of Professor 
Sargent, Arnold Arborstum, by whom a supply was 
presented to Kew in 1909. There was, however, a 
previous introduction of this species, also by means ol 
seed obtained by Mr. Wilson, but on behalf of Messrs. J. 
Veitch and Sons. The species has reached the stage ot

flowering after an unusually brief period, for some of the 
plants raised in 1909 produced blossoms in 1913. Cer- 
tainly one of the most distinct of the new Chinese 
Rhododendrons, B. Souliei falls within that group of the 
section Eurhododendron in which the leaves are glabrous 
and have no glands. Within this group it may be at once 
recognised by its long-petioled wide-based, leaves, its 
well-defined calyx-lobes edged with red glands, and its 
flat saucer-shaped flowers. At Kew it has thriven well 
in a semi-shaded position and is of low, bushy habit.

The Manchurian Hazel belongs to a group in which 
the involucre is prolonged beyond the nut into a tube 
sometimes measuring 1 J in. long, and is covered, particu- 
larly in the lower part, with yellowish bristly hairs. Its 
affinities with the Eastern North American C. rostrata, 
Ait., are so evident that it is not always easy to distin- 
guish it. In C. mandshurica, however, the leaves are 
usually broader and are often more or less deeply lobed 

August, 1915. 



in the upper part, though in the specimens from the 
Kew plant the lobing is not pronounced ; the young 
shoots are generally furnished with a more abundant 
soft pubescence, and the petioles as a rule are longer. 
C. rostrata, var. calif ornica, A.DC. (C. calif arnica, Rose), 
closely resembles C. mandshurica in its leaves which are, 
however, less markedly lobed ; moreover, it has glandular- 
hispid young shoots, a shorter involucre and a thicker 
nut-shell. C. mandshurica, var. Fargesii, Burkill, from 
Szechuan, differs from the type in having narrowly ovate 
leaves apparently not cordate at the base. C. Siehol- 
diana, Blume (C. rostrata, var. Sieboldiana, Maxim.), a 
Japanese plant, has a much shorter tube to the involucre 
and differs also in leaf characters. 

C. mandshurica is common in mountainous districts in 
Eastern Manchuria, and forms dense thickets in shady 
and dry woods. It was first, collected bv Maximowicz 
near to the Amur River in 1855. It is' also recorded 
trom Corea, from the provinces of Shingking and Chihli 
in Northern China, and from Yesso and Nippon in 
Japan. Its introduction to Kew dates from 1882 when 
nuts were received from the late Dr. E. Bretschneider ; 
ten years later the plant was received from Prof. Sargent 
ot the Arnold Arboretum, and again in 1906. The 
material for the figure was furnished by one of the plants 
raised at Kew from the seed received from Dr. Bret- 
schneider. It is a bush about five feet high and is

. The Senecio which forms the subject of our illustration 
is a native of South Africa, where it is known to occur 
throughout the coast region from the district of Rivers- 
dale as far as Algoa Bay. There are one or two earlier 
but doubtful records which connect the species with the 
Table Mountain region, but there is no definite proof of 
its presence there now. The late Dr. Harvey included 
S. glastifolius in the group of species of a shrubby or 
almost shrubby character which he designated the 
Eigidi. At the same time there is no doubt that it is 
extremely closely allied to another species from the same 
general region, S. multibracteatus, Harv., which has been 
referred by its author to the group Annul recognised by 
him. From S. glastifolius it is very easy to distinguish 
S. multibracteatus owing to the scabrid leaves and more 

August, 1915. 







copiously bracteate peduncles of the latter 
Herbarium material of S. glastifolius shows that there 
considerable variation in the shape, texture and toothing 
of the leaves. These changes of appearance, which may 
be due to the conditions under which the plants have 
grown, leave the flower-heads remarkably uniform and 
unmistakable on account of the numerous exterior supple- 
mentary bracts. From a remark in the note which 
accompanies a full-page illustration of the species in the 
Gardeners' Chronicle for 1910, it would appear that 
S. glastifolius was raised by Messrs. Sutton and Sons 
from seeds received by them from the district of George, 
immediately to the east of Riversdale. The plant from 
which the figure here given has been prepared was pre- 
sented to Kew in 1913 by Mr. H. Rabjohn, Twickel, 
Delden, Holland, and flowered in a greenhouse in April, 
1914. It is a perennial, is easily propagated by cuttings 
and grows into an elegant upright plant, about four feet 
in height, flowering during April and May. It does well 
if given conservatory treatment and grown along with 
greenhouse Cinerarias, but it may be noted that Mr. 
Rabjohn, in the Gardeners' Chronicle, writing from 
Welbeck Abbey, Worksop, in 1910, has described it as 
being vigorous in an open border, resisting successfully 
ten degrees of frost, though succumbing when the 
thermometer fell to 15°.

This remarkable Poplar is one of the many plants first 
collected in China by Mr. A. Henry, who found it in the 
districts of Chienshih and Patung, Hupeh, in 1888, and 
noted that it was common on the mountains at 4000 to 
6000 feet. It was afterwards collected at Tchenkeoutin in 
Szechuan by Farges, and in 1900 it was introduced into 
cultivation by Messrs. Veitch and Sons through Mr. E. H. 
Wilson, who being unable to introduce the tree by 



of seeds, sent home a living plant. It is from this 



individual, which grew in the Coombe Wood nursery 



September, 1915. 



until the sale of the collections there, that the specimens 
in collections in this country have been propagated. As 
regards size of leaf Populus lasiocarpa is undoubtedly the 
finest of all the poplars of which we have knowledge. 
Even a double plate of this work is insufficient to show 
the dimensions of its leaves in full; the blade not 
infrequently measures fourteen inches in length by nine 
inches in width and, whatever the measurement, is 
conspicuous for the rich red of the midrib and chief 
veins and petiole. In vegetative characters our tree 
resembles P. heterophylla, Linn., of the Eastern and 
South-eastern United States ; its catkins, however, are 
very different, and its closest ally is doubtless P. glauca, 
Haines, from Tonglo in Sikkim ; like this latter species 
it has polygamous flowers. The few flowering catkins 
seen were obtained from a cultivated plant, and may not 
be characteristic of the species. It should be mentioned, 
however, that P. glauca, so far as Mr. Haines has observed, 
produces in the wild state female or more frequently only 
hermaphrodite flowers; he found no male tree. The 
male catkins accompanying Henry's specimens were 
picked up from the ground beneath a leafless tree in 
South Patung, and Prof. Oliver cautiously dealt with 
them as possibly not belonging to P. lasiocarpa. The 
flowers have much longer pedicels than those of the 
cultivated plant, and the disk is distinctly oblique. The 
anthers agree. Populus lasiocarpa flowered in 1914 in 
the gardens of Mr. F. C. Stern, Highdown, Goring-by- 
bea , Sussex, and of Sir Harry Veitch, East Burnham 
Park, Slough, and the figure was prepared from material 
received from the former supplemented by catkins of more 
mature fruits from Sir Harry Veitch. The species thrives 

W i? j° n deep loam ' and ' like most poplars, enjoys 
abundant moisture at the root. Hitherto it has been 

propagated by grafting on stocks of the Black Poplar 
group but it will eventually, no doubt, be found to 
succeed better on its nxvn rnnto

The Gladiolus here depicted was discovered by Mr. C.J. 
Meller in 1861 on the Manganja Hills, Nyasaland, during 
the Zambesi Expedition led by Dr. Livingstone. Since 
then G. Melleri has been found to occupy a considerable 
area in Eastern Tropical Africa, for it has been collected 
at various localities in British Central Africa, in Portuguese 
East Africa, in the Matabele country and in Mashonaland. 
The plant which has formed the subject of our plate 
flowered at Kew in October, 1913, the corm having been 
received in June from Mr. A. Hislop who had obtained 
it at Makoni Kop, Rusape, Rhodesia. The nearest ally 
of G. Melleri is G. Buchanani, Baker, another Nyasa- 
land species, in which, however, we find several well- 
developed leaves about as long as and produced along 
with the inflorescence, instead of only one rigid far 



produced leaf with several much shorter sheathing leaves 
as in our plant. Grown in a greenhouse with other

affords an interesting contrast with most of them.

The genus Ornithoboea was originally based on a solitary- 
species from Tenasserim, sent to the late Sir William 
Hooker by the Rev. C. P. Parish over half a century 
aero, though a description of Parish's genus was not pub- 
lished until 1883, when Mr. C. B. Clarke named the species 
0. Par/shii. Thirty years later Mr. Craib added two more 
species, 0. Ilennji discovered by Mr. A. Henry in Yunnan, 
near the Burmese frontier, and 0. Lacei, sent by ^Ir. J. H. 
Lace from Upper Burma. Since 1913 Craib has described 
yet another, 0. lanata, found by Dr. A. F. G. Kerr in 
North-western Siam. Another form sent from the same 
region by Kerr, which comes near 0. Lacei, has flowered 
in the Botanic Garden of Trinity College, Dublin ; yet 
another, known only in fruit, occurs in Tonkin. The first 
record of this Indo-Chinese genus in cultivation relates to 
Kerr's two Siamese forms, flowered at Dublin by Professor 

September, 1915. 



) 



Dixon ; 0. lanaia, sent by Kerr, has also flowered at Kew. 
The plant of 0. Lacei now figured was raised at Kew from 
seed found in a capsule of the herbarium type of the species. 
Cultivated plants differ from the parent in having longer 
petioles and larger leaves. They flowered in June, 1914, 
in a warm greenhouse under the treatment suitable for 
tropical and subtropical Gesneriads, and matured good 
seed. In its twisted fruits Ornithohoea resembles Boea and 
Streptocar pus ,but its capsules are shorter and stouter; from 
both genera it is distinguished by the bilabiate corolla 
with short upper lip. 

Description.— Herb, apparently biennial; stem with 



portion, produced during the first season, over 



4 in. long, nearly £ in. thick, more or less 4-angled 
densely clothed during the second season with the per- 
sistent bases of the old petioles, rather closely hairy 
especially towards the top ; upper flowering portion of 
the stem usually about 12 in. long, everywhere glandular- 
hairy. Leaves usually unequal-sided, generally wide- 
ovate, acuminate, or somewhat acute or obtuse, one 
side often J shorter than the other, margin crenate- 
serrate, 1^-4 in. long, 1-3J in. wide, chartaceous, rather 
hairy on both sides, and on the lower paler side also 
minutely yellow-glandular, lateral nerves about 10 on 
each side of the midrib, visible above and raised beneath 
as are the transverse veins; petiole up to 4 A in. long, 
glandular-hairy Cymes axillary, half as long as the

The very striking Metrosideros here figured is a native 
of New Zealand, in which country the genus is well 
represented, three of its members having already a place 
incur pages: M. flmda, Sm., at t. 4471; M tementosa 
A. Rich., at t. 4488; and M. buxifoha, A Cunn., at 
t 4515. In our earlier volumes, too, five other figures 
have been given of Australian plants then referred to 
Metrosideros: M. citrina, Curt., at t. 260; M speciosa, 
Sims, at t. 1761 ; M. saligna, Sm at t 1821 ; MMspiaU^ 
Sm., at t. 1960; and M. viridiflora, Sims^ at t. J™& 



of these Australian species 



the 



M. hispida, which is Angophora cordifolia Cav., have now 
been better transferred to the genus Calhstemon. 1 he 
species now illustrated, M. diffusa, is confined to the 
North Island of New Zealand, where it is not uncommon 
in forests from Mongonui and Ahipara to the south-east 
coast and Taranaki, occurring from sea-level to elevations 
of 2000 feet. For its introduction to this country norti- 

Skptbmbrb, 1915. 



culture is indebted to Capt. A. A. Dorrien-Smith, who 
informs us that while it usually grows as a creeper and 
prefers to have its roots in the shade, it is in its native 
haunts very accommodating, as it also forms a fairly 
compact rigid shrub in the middle of lava-flows. Its 
usual and apparently natural habit, however, is that of 
a creeper on trunks of trees, when, like various species of 
Ficus, it forms more rigid spreading branches as it grows 
older. It is only on such branches, when they are mature, 
that flowers are borne. The material for our figure has 
been derived from a plant cultivated by Mr. T. A. 
Dorrien-Smith in his garden at Tresco Abbey, Scilly, 
where it has thriven well in a raised pocket against a south 
wall shaded from the midday sun, its roots attaching 
themselves to the stones like ivy. Under these congenial 
conditions it flowered for the first time from the spread- 
ing branches in April, 1914, doing so again, even more 
profusely, in 1915. It is readily reproduced by cuttings 
struck under a bell glass in autumn, plants so raised 
flowering in their second or third season. It can also be 
raised from seed, but plants so obtained take many years 
to attain mature growth and produce flowers. It should 
be noted that this is not the plant figured as M. diffusa 
at t. 569 of the Icones Plantarum ; that figure represents 

M. alb i flora, Sol.

The handsome tree now figured belongs to that section 
of Pyrus which Roemer established as a separate genus, 
Eriolobus. To it belong also the Japanese P. Tschonoskii, 
Maxim., figured at t. 8179 of this work, and P. trilohata, 
DC, a native of Syria, very rare in gardens but repre- 
sented in the Kew collection. Eriolobus differs from the 
Aria group, in which Franchet placed P. yumtanensis, by 
the styles being united for their lower third or more, and 
from Malm by the flesh of the fruit having grit-cells. 
The tree from which our figure was prepared is now 
growing in the collection of Pyrus immediately south of 
the Temperate House at Kew. It was purchased in 
1913 from Messrs. Veitch, who raisad it in 1900 in their 
Coombe Wood Nursery from seed sent from the district 
of Chang-yang in Western China by Mr. E. H. Wilson. 
A tree heavily laden with the handsome fruits was 

October, 1915. 



exhibited under the name P. Veitchii, at the Horti- 
cultural Hall, Westminster, on Oct. 8, 1912, by Messrs. 
Veitch. P. yunnanensis was originally discovered by the 
Abbe Delavav in Yunnan, growing in mountain woods 
at 9000-10,000 feet elevation. From P. Tschonoskii, its 
nearest ally, it is distinguished by its smaller flowers, 
much more numerous in the corymb, the smaller red 
fruits, and the more deeply lobed leaves of the barren 
shoots. Dr. Schneider describes the calyx -lobes as falling 
from the apex of the fruit, and stress has been laid on 
this statement under t. 8179 of the present work, but 
none of the specimens in the Kew Collection exhibit this 
character. It promises to be perfectly hardy and its 
abundant seeds will make its increase easy. Planted in 
good deep loam it grows well and, more especially 
in autumn, makes an attractive feature in the garden. 

Description. — Tree, 20 to 30 ft. high, unarmed; 
young shoots at first felted, becoming glabrous and 
reddish-brown. Leaves deciduous; ovate and finely 
and irregularly serrate on the flowering shoots, often 
more obovate and shallowly lobed as well as serrate on 
the barren shoots, acute at the apex, cordate or rounded 
at the base; 2-4| in. long, 1J-3 in. wide; primary 
veins six to nine ; ~dull green and at first floccose, ulti- 

glabrous above, covered with a pale brown 



felt beneath, much of which falls away by autumn 



petiole §-l| in. long, pubescent. Flowers f in. wide, 
in racemose corymbs 2-2J in. in diameter, terminating 
short, felted twigs which carry three or four leaves; 
rachis and pedicels felted, the latter about 1 in. long. 
Calyx felted, its lobes T \ in. long, triangular, becoming 
reflexed. Petals pale pink, { in. wide, orbicular, with 
a short, bearded claw. Stamens about twenty, filaments 
glabrous, anthers yellow. Ovary 5-celled; styles five, 
connate in the lower half. Fruit elobose. "A in. in 



diameter, deep red specked with whitish dots, the 
calyx-lobes persisting at the apex; flesh gritty, harsh 
and acid. Seeds £ in. long, hatchet-shaped, brown.

The interesting Chinese Gentian now figured is a 
member of the section of the genus Gentiana distinguished 
by Professor Kusnezow as Apt era. According to the 
arrangement adopted by Kusnezow G. gracilipes should be 
placed nearest to G. dahurica, Fisch., with which except 
for its longer pedicels it agrees closely in its general 
facies; or alternatively next to G. Fttisowii, Maxim., 
with which it shares the character of a spathaceously 
divided calyx. For the material on which our plate of 
G. gracilipes is based we are indebted to the kindness 
of Mr. H. J. Elwes, in whose garden at Colesborne, 
Cheltenham, a plant which flowered there in August, 
1914, was raised from seed collected in Kansu and 
received at Colesborne through the late Mr. R. Wood- 
ward. This plant, which was presented by .Mr. Elwes to 
Kew, has proved quite hardy and thrives vigorously m a 
cool sheltered corner. It has not yet ripened seed, but 

October, 1915. 



appears to be as easily managed as the other members 
of the section Aptera, of which several are already in 
cultivation. The chief distinctive feature of G. gracili- 
pes is the length of its slender pedicels, which arise 
singly in the axils of the uppermost leaves of the 
flowering shoot. The lateral position of the flowering 
shoot this species shares with G. dahurica ; the spatha- 
ceous division of the calyx on one side it shares not 
only with G. Fetisowii, but with G. straminea, Maxim., 
and some other members of the section Aptera. At the 
same time this latter character is not universal in the 
section ; several of the species, in addition to G. dahurica, 
have a normally tubular calyx. 

Description. — Herb, perennial, with barren rosettes, 
and at the same time, erect or ascending terete glabrous 
flowering stems. Leaves of the rosette narrow-lanceolate, 
acute; of the stem linear-lanceolate, acute, 1-nerved,

1 i~ 1 2 m. wide. Flowers solitarv in the axils of the 
uppermost leaves, pedicels glabrous, about 2 in. long.

The genus Promenaea was founded by Lindley oyer 
seventy years ago on four small Brazilian species which 
had until then been included in Maxillaria, Ruiz et Pav., 
along with a fifth from British Guiana ; some other species 
have since then been described from Colombia. The late 
Professor Reichenbach subsequently included Promenaea, 
with other allied genera, in Zygopetalum, proposed by Sir 
William Hooker in 1827. In this Reichenbach was 
followed by Bentham and Hooker in 1883, though they 
accorded Promenaea the status of a section. Reichenbach, 
however, had already reconsidered his earlier conclusion, 
and Promenaea is now thought as entitled to generic rank 
as some other similar groups whose status has never been 
questioned. One species of this genus, P. graminea, LindL, 
from Guiana, has been figured at t. 3877 of this work 
as Maxillaria stapelioides ; the true P. stapelioide* is, how- 
ever, a native of Brasil. The interesting little species 
now figured has a somewhat obscure history, for we are 
still without definite record of its native country. The 

October, 1915. 



plant is one in the Kew collection which thrives well in a 
tropical house under the conditions suitable for species 
of Maxillaria and Zygopetalum, and flowered there in 
June, 1914. It had been presented to the Gardens by 
the Dowager Lady Lawrence, earlier in the year, as part 
of the collection of the late Sir Trevor Lawrence, at 
Burford, Dorking, so rich in species previously unrepre- 
sented at Kew and rarely met with in cultivation. This 
species, P. microptera, was described in 1831 by Reichen- 
bach, whose material, which came originally from Mr. 
d'Haene of Ghent, had been sent by Mr. H. Veitch ; a 
day later he received it also from Mr. B. S. Williams of 
Hollo way. In 1890 material, probably from the original 
source, was communicated to Kew from the Royal 
Botanic Garden, Glasnevin, and there is little reason to 
doubt that the plant now figured had also formed part 
of the same importation, for the Burford label indicates 
that it reached Sir Trevor Lawrence from the collection 
of Mr. Williams. The nearest ally of P. microptera, as 
Professor Reichenbach and Mr. Rolfe point out, is a 
Brasilian species, P. mnthina, Lindl. ; this does not, by 
itself, entitle us to assume that P. microptera is also a 
native of Brasil rather than of Colombia or Guiana, 



though it suggests that possibility.

Turrill. 



The genus Streptocarpus is confined to Africa south of 
the Tropic of Cancer and to the Mascarenes. Two sections 
are generally recognized ; one, Unifoliatae, has only one 
green assimilating leaf which is a persistent cotyledon ; 
the other, fiosulatae, has 1-4 leaves in addition to the 
cotyledon which is usually present. The species figured 
is one of the Unifoliatae, of which about fifteen are 
already known from various parts of South Africa. The 
nearly or quite glabrous leaf (cotyledon) of & denticulaia 
is unlike the densely hairy one of S. pusilla, Harv., 
to which our plant appears most nearly allied. The 
glandular-pubescent character of the inflorescence is a 
noticeable feature, though our species shares this with 
some of the others. The general colour of the flowers 
is distinctive, and may be described as rose-purple with 
lines of deeper carmine on the lower lip, and dark- 
purple blotches on the lower part of the upper lip. 
In other species of Streptooirpus figured in this work 
the corolla is more or less blue or violet, as, in S. 

October, 191.">. 



Galpini, Hook, f., at t. 7230 ; S. Wertdlandii, Daramann, 
at t. 7447 ; and S. Makoni, Hook, f., at t. 7857. The 
material for our plate has been derived from a 




presented to Kew by Mr. R. I. Lynch, Bot 



Garden, Cambridge, in 1914. This plant was raised 
by Mr. Lynch from seed communicated by Mr. W. E. 
Ledger, Wimbledon, who had received it from South 
Africa, where it had been collected by Mr. J. N. Thorn- 
croft on one of the mountains near Barberton, in the 
Transvaal. It has thriven well under the conditions 
suitable for other species of the genus, and has ripened 
seeds from which a second generation of plants has been 
raised. Crosses, Mr. Lynch informs us, have been made 
between S. denticulata and various species, more especially 
S. cyaneus, S. Moore, with which it seems to pair more 
readily than with others. In the case of S. cyaneus, crosses 
have been made both ways, and in each the influence of 
the female parent has shown itself the stronger. 

Description.— Herb, stemless and with only one leaf, 

which is an enlarged persistent cotyledon. Leaf ovate,

The striking form of Clematis uncinata which is the 
subject of our plate differs from the plant originally 
described as C. uncinata by Champion, by its leafy 
inflorescence, that of the type being comparatively 
leafless, and by its leaflets being all retuse in place ot 
acutely acuminate and recurved or almost hooked at 
the tip, the feature to which the species owes its name. 
Yet in spite of the distinctive appearance thus imparted 



the present form, the 



ted by 



a series of intermediate conditions, the existence of 
which renders it impossible to accord our plant even 
the rank of a variety. For the material from which our 
illustration has been prepared we are indebted to Captain 
D. V. Pirie, in whose garden at the Chateau de Varennes, 
a few miles west of Angers, it makes a most beautiful 
picture, clambering over a wall and succeeding under the 
strong sun of Western France much better than it dors 
at Kew. Fragrant as well as graceful, C. uncinata is 
evidently a species which loves bright sunshine. In 

October, 1915. 



England it does not appear to be very hardy in the 
open ground and will probably require to be grown on 
a south wall in order to bring out its best qualities.

subject of our plate is a native of Northern Burma, where 
it was met with at an altitude of about 7500 feet above 
the level of the sea in the Northern Shan States by 
Major C. W. Browne, Survey of India, by whom a 
supply of seed was sent to Col. F. B. Longe, Holly Lodge, 
Thorpe, Norwich. From these seeds, sown in July, 1909, 
Col. Longe was able to raise several plants ; one of these 
plants, which flowered in 1914 under the conservatory 
treatment suitable for R. formosum and /?. Veitcha, was 
sent to Kew for examination, and afforded an oppor- 
tunity for the preparation of the figure here given. 
According to the information received by Col. Longe, 
this species in its natural state affects open grassy hill 
sides away from any large trees, prefers western slopes, 
and only grows to a height of about three feet. The

flowers in their native habitat are of a crimson pink 
which gradually turns to a delicate white, or to white 
suffused with pink. The affinity of R. carneum with 
E. I eitchianurn, Hook., also a Burmese species which 
has been figured at t. 4992 of this work, is very marked, 
and if only herbarium material of the two be consulted, 
the impression might be formed that they are barely 
separable. When, however, the figures made from 
living material of the two species are compared, several 
differences are manifest. In R. V eitddanum the calyx- 
lobes are usually considerably larger, and are always less 
ciliate, while the corolla, which is white, is always larger 
and is yellow inside the tube, its lobes being suberect in 
place of spreading and having strikingly crispate margins.

.The Orchid now figured is a member of a small but 
interesting genus which was originally founded by the 
late Professor Reichenbach in 1871 on a species from 
Costa Rica described as Sievekingia suavis. To the genus 
Reichenbach subsequently added two more species, 
*S'. fimbriata, also a Costa Rica plant, and S. Jenmanii, a 
native of British Guiana. Since then a plant from 
Ecuador, originally described by Mr. F. C. Lehmann as 
Gorgoglossum Reicltmbachianum, has been found to be in 
reality a Sievekingia, and has been figured at t. 7576 of 
this work as S. Reichenbachiana. More recently two 
additional species have appeared in collections. One of 
these, a native of Peru, has been described as S. 'peruviana, 
Rolfe. The other, S. Shepheardii, now first described is 
a native of Colombia. Jt is one of nine Orchids collected 
in the Colombian district of Rio Condoto Choco by 
Dr. S. Shepheard in 1912 and was acquired for the Kew 
collection frcm Mrs. Shepheard, Abbots Hall, Aylsham, 
in 1914. It flowered in the Tropical Orchid House at 

November, 1915. 



Kew in February, 1915, and so permitted our plate to be 
prepared. Planted in a teak basket and suspended near 
the roof-glass, it thrives well under the treatment suit- 
able for members of the genus Stanhope a. Its cultural 
requirements are thus in accordance with its natural 



affinities for, when first described, the srenus was noted 




as being allied to Lacaena, Lindl., which in the Genera 
Plantarum was placed in the subtribe Cyrtopodiea", but 
has since been more satisfactorily transferred to the sub- 
tribe Stanhopieae, wherein Sieve kin gia is most appropriately 
included. The two species from Costa Rica are unknown 
now in orchid collections; those from South America 
appear, perhaps owing to difficulties connected with 
their culture, to have failed to secure a permanent 
position in our gardens.

The Anemone here figured was collected by Mrs. 
Wheeler CufTe at a high altitude on Mount Victoria, a 
peak 12,500 feet in height in the Arakan Yomah in 
Western Burma. Attempts, all of which had proved 
unsuccessful, had been made to send seeds to Europe 
but, during a visit which Mrs. Cuffe was able to pay to 
Mount Victoria in 1913, she was able to obtain plants 
which she brought home herself and presented to the 
Royal Botanic Gardens, Glasnevin. Here they throve 
well in a cold frame, where they have passed uninjured 
through two winters, flowering freely in .May and June. 
From one of these plants, sent by Sir Frederick Moore for 

November, 1915. 






the purpose, our plate has been prepared. The species. 
A. obtusiloba to which this interesting Burmese plant is 
here referred, was first described by Mr. D. Don in 1825 
from specimens sent home by Dr. Wallich from Gossain 
Than in the Alps of Central Nepal. Its range of distribu- 
tion, tor an alpine species, is unusually wide, for it

The subject of our plate is one of the most attractive 
and, from the cultural standpoint, one of the most 
distinct of the various shrubby Potentillas added to our 
collections in recent years. It is a native of upland 
thickets in Szechuan and Western Hupeh at elevations 
of over 6000 feet above sea-level, and was introduced 
from this area by Messrs. J. Veitch and Sons through 
their collector, Mr. E. H. Wilson, in 1900. It flowered 
under cultivation for the first time in their nursery at 
Coombe Wood in 1902. In 1907 Mr. Wilson sent plants 
from the Arnold Arboretum on behalf of Professor 
Sargent, and in 1911 he treated the plant as a distinct 
species, P. Veitchii. In 1912 another plant raised from 

November, 1915. 



Northern Chinese seed was received at Kew under the 
same name from the Arnold Arboretum. This flowered 
in the hardy collection here in 1914 and from it the 
material for our plate has been obtained. This plant 
differs from the one from Western Hupeh in having less 
hairy leaves with less prominent lateral veins, somewhat 
smaller outer sepals and petals, and a rather longer style 
more attenuated towards the base. In other respects 
the two plants agree. But while sufficiently distinct as a 
garden-plant, there is little doubt that the form here 
figured must be looked upon as one intermediate between 
P. fruticosa, Linn., and P. davurica, Nestl. Several such 
forms with whitish or pale sulphur-coloured flowers are 
known from Eastern Siberia and Manchuria, where the 
areas of these two species overlap; they appear to 
correspond with the different variations referred to the 
reputed garden hybrid, P. Friedrichseni ', Spath. Our 
plant has indeed already been referred as a variety to 
P.frutwosa by Mr. Bean in his excellent work on " Trees 
and Shrubs Hardy in the British Isles," and that it must 
be accorded treatment of this kind is indisputable. 
.Perhaps, however, it is on the whole preferable to reduce 
it to the other species of the pair, P. davurica, a plant 
well known in cultivation and figured at t. 3676 of this 
work as P. glabra, Lodd., which has leaflets that, even in 
Dud, are glabrous except for a few hairs along the 
margins, and is in its native country a dwarf compact 
snrub. lhere are other distinct varieties of P. davurica ; 
one with a dense and shaggy torn ent urn from Manchuria 
nas been distinguished under P. fruticosa, not under 
its proper species, as var. mandschurica, Maxim. ; another 
with silvery leaves occurs in Western China. P. 
aarunca vm. Veitchii, in its native country affects open, 
rocky situations, fully exposed to the sun. Mr. Wilson 
aescribes it as being remarkably floriferous ; though at its 
oest m early summer, it flowers continuously from May 
tin late autumn, producing its sprays of snow-white 
nou ers well above the grey-green foliage. In cultivation 
it makes a shapely low bush and flowers continuously 
from May until September. It likes a loamy soil and an 
open, sunny position, and may be propagated by cuttings 
made m July and August. 



Description. — Shrub, evergreen, 3-5 ft. high ; stems 
and branches woody, the younger more or less silky, the 
older sparingly hairy, the bark flaking. Leaves f-1 in.

beneath, adpressed silky or in the cultivated plant 
sparingly hairy on both surfaces, lateral nerves more or 
less raised beneath ; stipules ovate, acuminate, £ in. long,

The interesting Japanese Araliad now figured has 



been known 



It is the original 



Aralia japonica of Thunberg, but was separated from the 
genus Aralia by Decaisne and Planchon, when these 
authors revised the Araliaceae, because of its different 
floral structure. The name Fatsia, given by them to 
the newly established genus, was bestowed owing its 
being believed that the native name of our plant 
is Fatsi. It is not certain, however, that this is 
the case; according to Franchet and Savatier, the 
Japanese name is more correctly written Iats'de. These 
latter authors included in the genus a second species, 
F. horrida, which is, however, better referred to Echiruh

panax, Dene & Planch., and has for this reason been 
figured as E. horridus at t. 8572 of this work. Another 
species was added to the genus by Bentham and Hooker 
as F. papyrifera ; this species, which has with justice 
been transferred by C. Koch to the genus Tetrapanax, 
has also found a place at t. 4697 of this work under its 
older name Aralia papyrifera, Hook. The plant now 
figured, which is thus the sole representative of its genus, 
though a common feature in collections for over sixty 
years, has chiefly been in use as a decorative plant in 
conservatories. It is, however, hardy in the average 
climate of Great Britain if it be given a sheltered 
situation. Plants put out in 1891 have succeeded well in 
the Bamboo Garden at Kew, and although they suffered 
somewhat from the great frosts of February, 1895, they 
were not destroyed, and that has been the only occasion 
on which they appear to have been affected by cold. At 
the same time this shrub is to be seen at its very best in 
the gardens of our southern and western counties. 
Flowering, as it does, in late autumn, its huge panicles 
produce a particularly striking effect in October and 
November, when there are few other plants in blossom. 
If F. japonica can be afforded a position which is sheltered 
from the sun during the middle of the day, it does better 
than in more exposed situations. It likes a loamy soil, 
and is increased by placing cuttings of a fairly firm 
growth singly in pots plunged in a mildly heated pro- 
pagating frame. 

Description.— Shrub, 3-13 ft. high, unarmed ; stem 
terete, without prickles, leafy. Leaves petioled, 7-9-lobed,

The Spindle-tree which we figure here is one which 
appears to be common in Japan and extends into Corea 
without, however, occurring in China. It has very much 
the appearance of the European Euonymus tatifohus, 
Scop., and in flower might be mistaken for that plant. 
Its fruits differ, however, in being unlobed, and thus 
serve to distinguish it. The plant of E. oxyphyllus from 
which the material for our plate has been obtained was 
received at Kew from the Arnold Arboretum in 1895. 
It is perfectly hardy and thrives well in a loamy soil. 
Like its European ally it is a small tree, at present eight 
to ten feet in height, very graceful in habit and extremely

attractive in September, when its branches are laden 
with brilliantly coloured fruits pendulous on long slender 
stalks. Each seed is completely enveloped in a fleshy 
scarlet imbricately five-lobed aril] us. These seeds are 
produced in abundance and render its propagation easy.

The subject of our plate, Iris bracteata, has been in 
cultivation in the Iris Collection at Kew for a consider- 
able number of years, and the material for our figure 
has been obtained from one of the oldest plants therein. 
The species was discovered in 1884 by Mr. T. Howell, of 
Arthur, Oregon, in the Walds and Dear Greek Mountains 
of Josephine County close to the southern boundary of 
the state, where it flowers in the latter part of April and 
in May. Under the cultural treatment suitable for most 
species of Iris it thrives well in this country, flowering a 
fortnight later than it does in its native habitat. 

December, 1915. 



According to Mr. S. Watson, the veining of the falls, so 
marked a feature in the plants grown in England, is not 
a constant character, while Mr. Dykes in his monograph 
of the genus Iris points out that under cultivation in 
this country, various colour varieties or hybrids have 
appeared in which the yellow of the flowers in the wild 
plant has been replaced by red, almost crimson ; in this 
case, however, the veining has persisted. Owing to the 
laxly branched rhizome 1. bracteata is of somewhat scanty 
growth, the leaf -tufts and flowering stems coming up in 
a scattered fashion. The lowermost leaves just above 
the scales are reduced to the sheathing portion and only 
one, or occasionally perhaps two of the leaves belonging 
to a tuft are of the normal Iris type. Mr. S. Watson 
has pointed out that the stomata of the leaves are in 
this species confined to the pale side of the leaf. 

Description.—//^, with a slender branching obliquely 
descending rootstock which is closely covered by the 
hardened remains of the firm bud-scales; leafy tufts clothed 
at the base by fresh firm brown imbricate scales. Leaves 
about four to each tuft, usually only one fully developed ; 
the two outermost very much reduced and sheathing 
almost throughout, the third about twice as long as the 
basal sheathing for two-thirds of its length, the upper- 
most fully developed leaf sheathing at the base only and 
reaching 1J-4J ft. in length ; all linear, acute, the la 
about F in. wide, all green on one side, paler green or 
somewhat glaucous on the other, main-nerves about 
» 7 10, slender but distinct. Stems with flowers 4-6 in. 
High to the bases of the spathes, clothed below with 
scales like those of the leafy tufts, the uppermost scales 
passing into leaves, usually 3 in number, which are 
reduced to sheaths 1J-3 in. long. Spathes lanceolate, 
acuminate, 2-2$ m. long, green, with thin membranous 
margins, slightly keeled along the centre behind. Flowers

Prunus Maximowiczii belongs to the MahaUb section of 
the cherries, but is distinguished from the other cultivated 
species of that group by the conspicuous foliaceous bracts 
on the inflorescence. It is closely allied to P. szeckuanica, 
Batalin, a species probably not in cultivation, which 
differs by its subumbellate inflorescence, its much shorter 
peduncle but longer pedicels and by its conspicuously 
glandular bracts very villous beneath. Originally 
discovered in Eastern Manchuria and described by 
Ruprecht in 1857, P. Maximowiczii has since been found 
in Japan, Sachalin and Corea. It did not reach this 
country until 1895 when it was sent to Kew by Prof. 
Sargent from the Arnold Arboretum, to which estabhsh-

merit he had introduced it from Japan three years 
previously. It has succeeded very well and proved to 
be quite hardy, forming a small tree of neat shape. 
The material used in the preparation of our plate was 
kindly supplied by Mr. T. Smith from his well known 
nursery at Newry, where the tree apparently bears fruit 
more freely than it does at Kew. There is some varia- 
tion in the degree of pubescence on the leaves. On 
Mr. Smith's plant it is almost confined to the midrib and 
veins beneath, but on one grown in the Kew collection 
the leaves are softly villous beneath. The glands on the 
teeth of the bracts and calyx-lobes also vary in their 



frequency and size. The foliage of this cherry turns a 



fine red colour before falling in both Japan and North 
America, but, owing probably to our duller skies, has not 
shown this quality with us. 



Description.— Tree, 20-30 ft. high, of spreading 
habit, young shoots clothed with pale hairs the first 
season, glabrescent and greyish-brown the second. 
Leaves ovate, oval, or obovate, cuneate to rounded at 
the base, shortly acuminate, irregularly and doubly 
serrate; 1J-4 in. long, j-1} in. wide; dull green, 
glabrous or slightly pubescent above, pubescent beneath

times slightly), f-4 in. long. Peduncle and pedicels
