This handsome species, Rhododendron auriculatum, is a 
native of Western Hupeh where, as Mr. E. H. Wilson 
informs us, it occurs scattered throughout woods without 
being anywhere common. It was first collected by 
Professor A. Henry, in 1885, near Ichang, and was met 
with again by him in subsequent years. Wilson obtained 
it in 1901 near Fang. In its native habitat this is the 
last of the Rhododendrons to come into flower and, as it 
maintains this characteristic in cultivation, this fact 
imparts to i?. auriculatum its most important feature 
from the garden point of view. At Kew, where the 
species is represented by examples acquired from Messrs. 
J. Veitch and Sons in 1908, it does not commence to 

January-March, 1919. 



grow until the latter part of July, and it flowers at th e 
same time. It may therefore be possible to found on it a 
race of hardy hybrids later in flowering than any now in 
existence, though it is difficult to find other Rhododen- 
drons flowering in July with which it can be crossed. At 
Kew it has been fertilised with pollen from a belated 
R. ponticum, Linn. ; it has also been crossed with the late- 
flowering form of R. decorum, Franch. In the wild state 
the flowers of R. auriculatum vary, so Wilson states, from 
white to rosy red. They are pleasantly fragrant, their 
odour recalling that of a freshly cut dessert apple. In 
foliage it is perhaps the finest of all Rhododendrons 
hardy in a climate like that of the Thames valley, though 
in milder districts larger leaves are borne by Himalayan 
species like R. Falconeri, Hook, f., and R. grande, Wight. 
The largest leaves of R. auriculatum measured have been 
thirteen inches long by five inches across. Though quite 
hardy at Kew, its greater luxuriance in Cornish gardens 
indicates that it prefers rather milder conditions. It 
should be grown in thin woodland or in some other 
position where it is protected from the midday sun.

The remarkable Brazilian Orchid which forms the 
subject of our plate was described and figured by Mr. 
Barbosa Rodriguez in 1877 from specimens growing on 
trees at Caldas, in the province of Minas Geraes. It had, 
however, been previously met with by Dr. G. Gardner, 
for there is a specimen of the same plant in the Lindley 
Herbarium which Gardner has noted as being a species 
of Maxillaria, collected by him in March, 1837, on the 
stems of trees in the Organ Mountains. To this speci- 
men Dr. Lindley added the note, " genus uncertain, 
the only flower was broken and injured by insects." 
Rodriguez when he described the plant, which he 
dedicated to H.I.H. Donna Isabel, Comtessa d'Eu, 
remarked that it is a very bizarre Orchid with almost 
the habit of a Maxillaria, but with a pollinary structure 
Janoaey-Makch, 1919. 



so different from that of Ma.rillaria that he placed his 
genus Isabella, with good reason, in the tribe Epidendreae, 
between Lindley's two genera Leptotes and Sophronitis. 
In the figure of /. virginalis supplied by Rodriguez, 
which serves as the frontispiece to his volume, the 
remarkable fibrous sheaths which clothe the pseudobulbs 
are shown as being more developed than they are in 
the cultivated plant here depicted. For the introduc- 
tion of this plant to cultivation, orchid-growers are 
indebted to Mr. K. Grossman, who sent living plants to 
the Botanic Garden at Berlin in 1904. The example 
now figured was received at Kew from the Director of 
the Berlin Botanic Garden in 1908, and has thriven well 
in an intermediate temperature attached to a block of 
tree-fern stem. Under cultivation it flowers very 
sparingly, the last occasion being December, 1917, when 
our drawing was prepared. It is by no means con- 
spicuous, even when in flower, for the solitary individual 
blossoms are small, and are borne on extremely short 
peduncles ; they are whitish with a light flush of rose or 
pale purple in the sepals. The flowers are, however, 
extremely interesting on account of their remarkable 
structure. 

Description.— Herb, epiphytic, small, with a creeping cylindric rootstock.

scanous sheaths which at length become fibrous-laciniate. Leaves nearly 
cylindric, rather blunt, curved or flexuous, If -6 in. long, very narrow. Scapes 
short, slender, £-4 in. long, 1-flowered ; bracts spathaceous, blunt, very short ;

January-March, 1919. 



This Ipomoea, attractive both in foliage and in flowers, 
the latter being of a colour very unusual in the genus, 
has long been known in gardens. Its first recorded 
appearance was in the Calcutta Botanic Garden in 1812, 
where, according to Roxburgh, it sprang up accidentally 
amongst plants received from friends in the vicinity of 
Calcutta ; of its native place he was uncertain. Under 
the name of I. tuberculata it was figured and described in 
the Botanical Register in 1816, and it is there stated that 
the plant was raised from seeds collected in the Calcutta 
Botanic Garden, and sent by Sir Evan Nepean, it would 
appear early in 1815, to Messrs. Whitley , Milne and Brame, 
Nurserymen of King's Road, Chelsea.' Jacquin first met 
with it in the Vienna University Botanic Garden, where, 
he informs us, it was obtained amongst several unnamed 
Chinese seeds received from England in 1814. The 
species appears to have a wide distribution, but very 
probably it is not a native in some of the localities from 
which it is recorded. In India it is known from Simla, 
Rohilcund and the Deccan Peninsula. It is also known 
from Ceylon "in dry country, very rare," and from 
Java. There is no satisfactory evidence that it is 
native in China and Australia, though these countries 
are included in its range by various authorities. In 
Tropical Africa it ranges from Nubia, Abyssinia, the 
Egyptian Sudan, German East Africa to the Kwebe 
Hills in Ngamiland, and Upingtonia in South- West 
Tropical Africa. There is a very small-flowered speci- 
men in the Kew Herbarium labelled, possibly incorrectly, 
" C.B.S. Villette." The material for the accompanying 
figure was obtained from a plant raised from seeds 
received in 1917 from Major Howard of Richmond, and 
collected by him at Kilimatinde in German East Africa. 
The flowers vary considerably in size as shown by the 
plant cultivated at Kew, as well as by the dried speci- 
mens, and forms with unusually large flowers have been 
supposed to represent distinct species and have been 
described as such. It is possible also that the colour 
varies, for in one instance the flowers are said to be 
white. The curious little pouches, sometimes very 
conspicuous at the base of the outer sepals, appear to 
differ in size and in some of the dried specimens are 



scarcely noticeable. It is almost certain that /. saccata, 
Hallier f. (in Engl. Jahrb. vol. xxviii. p. 48), from German 
East Africa, of which there is no specimen at Kew, 
should also be referred to T. dasysperma. At Kew the 
species has been raised and flowered in a tropical house. 

Description. — Herb, apparently annual, everywhere quite glabrous. Stems 
twining, 6-8 ft. high or more, very slender, simple or sparingly branched, at 
times tuberculate. Leaves petioled, wide cordate-ovate, .1^-4 in. long and 
broad, 3-sect with the main lobes more or less narrowed at the base, and the 
central lobe 3-partite while the lateral are 2-3-partite, or at times pedate ; lobes 
lanceolate, acute or acuminate, quite entire, 1-8 in. long, i-f in. wide ; petioles 
i-2 in. long, occasionally with rudimentary leaves resembling stipules in their 
axils. Peduncles axillary, 1J-1J in. long, 1-3 (rarely 4)-flowered, with a few 
minute bracts. Sepals 5, elliptic with rounded tips, §-§ in. long, ±~l in. wide, 
their margins membranous, their bases outside with 1 or 2 small pouches or 
spurs. Corolla salver-shaped, glabrous ; tube 1-1 £ in. long, ^-f- in. wide about 
the middle, narrowed at the base, pale purple throughout and deep purple at 
the throat ; limb flattened, somewhat 5-angled, 2f-4 in. across, from straw- 
colour to sulphur-yellow, with 5 narrow greenish bands. Stamens 5 ; filaments 
pilose at the base ; anthers oblong. Ovary nearly globose, glabrous, encircled 
at the base by a narrow but stoutish disk ; style filiform, included, longer than 
the stamens ; stigma 2-lobed. Capsule globose, glabrous, about f in. across, 
2-celled. Seeds 2 to each cell, somewhat 3-gonous, about i in. long and broad,

The charming Rhododendron here figured was first met 
with by Mr. G. Forrest on the western flank of the Shweli- 
Salwin divide in south-western Yunnan in August, 1912, 
at elevations of about 10,000 feet and was found again 
by the same collector at similar elevations on open 
rocky slopes in the following June. Described at 
Edinburgh from specimens of the second gathering, 
R. callimorphum is now in cultivation in various collec- 
tions in this country and appears to be fairly hardy at 
Caerhays Castle in Cornwall, whence Mr. J. C. Williams, 
with whom alone it has yet flowered, supplied the 
material for our plate ; also at the Sunningdale Nurseries 

January-March, 1919, 



where, as Mr. H. White informs us, it has more than 
once experienced very severe frost, but has escaped with 
only slight injury ; and at Kew where an example which 
has lived out of doors for five years is quite healthy. 
In cultivation it has so far grown into a compact shrub 
about three feet high, bearing some outward resemblance 
to R. campylocarjmm, Hook, i, figured at t. 4968 of this 
work; its nearest ally, however, is R. Souliei, Franch., 
described at t. 8622. Marked features of R. callimorphum 
are its long petioles covered with red or blackish stalked 
glands, and its nearly cordate ovate-orbicular leaves with 
a distinct bloom on the underside. Occasionally one of 
the uppermost leaves is considerably reduced in size and 
spathulate in shape, while the petiole is widened and 
winged. It is not clear that this is a frequent feature 
in R. callimorphum ; it arrests attention owing to its 
rarity in species of Rhododendron proper, though it is of 
common occurrence in the Azalea section of the genus. 
It is perhaps too soon to predict the situation that will 
best suit R. callimorphum and lead to its attaining the 
dimensions of wild specimens. Those in shady positions 
are, however, at present growing more freely than those 
in fairly open spots.

The Aloe now figured was first discovered at Zanzibar 
by Sir John Kirk by whom it was presented to Kew. It 
has grown satisfactorily in a sunny tropical house where 
it flowers in the autumn and suckers rather freely. The 
original plant flowered at Kew for the first time not in 
autumn but in April, 1895, and when it was then 
described by Mr. Baker it still had " laxly rosulate " 
leaves, but by 1901 it had developed a stem thirteen 
inches high with scattered foliage. From the suckers 
several independent plants have been raised and one of 
these, which forms the subject of our plate, flowered at 
Kew in October, 1916. One of the plants had by 
October, 1918, developed two stems, eleven and thirteen 
inches high respectively, with five basal offsets from one 
to two inches in height. The stem is relatively slender, 
and the naked portion is conspicuous on account of the

gradual increase in thickness from the base upwards. 
Though erect or at least ascending in these cultivated 
plants, the appearance of the stem suggests that in wild 
ones it may be more or less prostrate, a suggestion 
strengthened by the inclined position assumed by the 
inflorescence. The leaves, which are remarkable for 
their closely set silvery white spots, are relatively small 
for the genus ; their sheaths are rather long and com- 
pletely encircle the stem. It is singular that since its 
original discovery this species has not again been met 
with in a wild state. In the division of the section to 
which A. concinna belongs are included two other Aloes, 
both nearly related to our plant, yet both readily dis- 
tinguished from it by their flowers, for one of them, 
A. squamosa, Baker, a Socotran species, has a shorter 
perianth, while the other, A. Dorotheae, Berger, a species 
of German East Africa, has a longer perianth than 
A, concinna.

The material on which our figure of the pleasing 
Primula now described has been based was received 
from Sir F. W. Moore, by whom it had been grown ab 
the Royal Botanic Garden, Glasnevin, under the name 
P. chasmophila, Balf. 1, in April, 1918. It is a native of 
Bhutan, where it was obtained by Mr. Cooper when 
collecting on behalf of Mr. A. K. Bulley, Neston, 
Cheshire, through whom the plant figured had reached 
Glasnevin. Professor Balfour, to whom the plant owes 
its name, has kindly informed us that Mr. Cooper's 
original material was all in fruit, and that although the 
plant flowered in the Royal Botanic Garden, Edinburgh, 
in 1917 the blossoms were mostly so imperfect as to 
render it desirable to defer the preparation of a full 
Januaey-March, 1919. 



description. In Bhutan the species is met with in dry 
sunny positions in rocky soil at about 16,000 feet above 
sea-level. P. chasmojMla is a member of the Soldanelloides 
section of the genus, whereof there are several species in 
the eastern Himalaya and Western China, most of them 
characterised by their diminutive size and relatively 
small leaves associated with large and conspicuous 
flowers, though usually they enlarge considerably after 
flowering. Perhaps the extreme of this condition is met 
with in P. uniflora, Klatt, a Sikkim species in which the 
leaves are remarkably small while there is but a single 
large flower. The nearest allies of P. chasmophila are 
the Chinese P. spicata, Franch., and the Himalayan 
P. Wattii, King.

The name Bulbophyllum robustum was originally used 
to designate a species based on specimens preserved in 
the herbarium at Kew which had been collected by the 
Rev. R. Baron in the Central District of Madagascar. 
In 1914, a living plant of a Madagascar Bulboph//l/um was 
presented to Kew by Sir F. W. Moore, Royai Botanic 
Garden, Glasnevin, and on flowering proved to be 
identical with the species discovered by Mr. Baron more 
than twenty years earlier. The species belongs to a 
somewhat small group of Bulbophylla in which the rachis 
of the inflorescence is clavately thickened. The shortly 
pedicelled individual flowers are tightly adpressed to the 
rachis, and are considerably dilated laterally, while the 
fleshy lip is immersed in a cavity formed by the united 
lateral sepals, the margins of these being denticulate. 
The nearest ally of B. robustum is B. crenulatum, Rolfe, 
another Madagascar species, figured at t. 8000 of this

work. Our plant differs from B. crenulatum in its stouter 
habit, its larger flowers and in the entire in place of 
denticulate angles of the ovary. The plant is grown in 
a basket suspended from the roof of a tropical house at 
Kew, and thrives well under the treatment suitable for 
other tropical species of the genus. It flowered at Kew 
in May, 1917, when the figure now published was pre- 
pared.

Protea longifolia, the subject of our plate, has had 
a long cultural history. It was first mentioned by 
Boerhaave in 1720. The specimens on which his account 
was based came from the mountains of Hottentot's 
Holland, on the boundary of the 'Stellenbosch and 
Caledon divisions of Cape Colony. The field-notes at his 
disposal enabled him to state that there it is rare, grows 
on mountain-slopes, has wide-spreading roots, a trunk 
about as thick as one's arm, which branches about 

January-March, 1919. 



eighteen inches above the soil-level and attains a height, 
with the branches, of some three feet. Burchell, who 
collected it nearly a century later in the Donderhoek 
Mountains near Villersdorp in northern Caledon, found it 
to be there very common, reaching a height of five to 
seven feet and resembling closely P. mellifera, Thunb., 
a native of the Coast Region of South Africa. The area 
occupied by P. longifolia covers practically the whole of 
the Caledon division and, if we include the form with 
smaller leaves and heads, which Mr. Phillips separates as 
var. minor, the species extends into the adjoining portion 
of the Bredasdorp division. Whether it were introduced 
in the time of Boerhaave or not, we know that towards 
the close of the XVIII. Century it was raised at Schon- 
brunn, from seeds sent or brought there probably by the 
Austrian collector Scholl. Messrs. Lee and Kennedy, of 
Hammersmith, received from Schonbrunn a plant or 
plants which flowered in their nursery early in 1801, 
and were figured by Andrews as P. longifolia nigra in 
the " Repository." But the same firm seem to have 
obtained, also from Schonbrunn, other specimens which 
likewise flowered in 1801 and were figured by Andrews 
as P. longifolia ferruginoso-purpurea. About the same 
time Hibbert had yet another specimen, likewise sent 
from Schonbrunn, which Andrews described and figured 
as P. longifolia, var. cono turbinate. But while Andrews 
was satisfied that all three were forms or varieties of 
P. longifolia, Sweet regarded them as distinct species 
which he named P. longifolia, P. ligulaefolia and P. um- 
bonalis respectively. A fourth figure purporting to 
represent P. longifolia was published in the " Botanical 
Register " in 1815. The plant in this case was again 
one belonging to Messrs. Lee and Kennedy ; this time, 
however, it was one introduced by Masson in 1790. 
Sweet accepted Masson's plant as true P. longifolia, but 
Phillips, relying on certain differences exhibited in t. 47 
of the " Register," has treated it as the basis cf a dis- 
tinct species, P. ignota. In the "Flora Capensis" 
P. ligulaefolia and P. umbonalis are similarly recognised. 
As no specimens of P. ignota, ligulaefolia or umbonalis 
appear to have been preserved when their respective 
plates were published, this course is possibly safer than 



the alternative one of including all three under P. iongi- 
folia. But while there is no conclusive evidence to 
justify the reduction of the three species proposed or 
accepted by Sweet and Phillips, it has to be remarked 
that the appearance of the flower-heads in the plant now 
figured suggests that these heads do not develop per- 
fectly and normally in our relatively sunless climate. 
This in turn raises the question whether those differences 
in the shape of the centre of the head, the length of the 
perianth-arms, and the colouring of the involucral bracts 
on which the separation of P. ignota, P. UgulaefoUa and 
P. umbonalis from P. longifolia depends, may not be fully 
explained by the adverse conditions with which any 
Protect has to contend when grown in this country. The 
plant now figured was raised at Kew from seed collected 
in the Caledon division by Miss M. Mason, to whom the 
establishment is indebted for many interesting South 
African plants. The seed was despatched from the Cape 
in March, 1911 ; the plant depicted was cultivated in a 
pot in a greenhouse where it has thriven well, and where 
it flowered for the first time, at an unexpectedly early 
age, in October, 1916. 

Description.— Shrub, 3-7 ft. high, with finely tonientellous or almost 
glabrous branches. Leaves narrow thong-shaped, blunt or somewhat acute, 
gradually narrowed to the base, 3-7 in. long, £-| in. wide, glabrous, nerves 
pennate, visible only above. Floiver -heads sessile, 4-6 in. long, about 4 in. 
across ; involucral bracts 9-10-seriate, glabrous, the outermost ovate or ovate- 
oblong, obtuse, green, with often dark apical spots, the inner with a lanceolate 
blade passing gradually into a claw and approaching or equalling the length of

It is now nearly eighty years since the Mexican Orchid 
here figured was first described by Professor Lindley. 
The original plant flowered in the collection of Mr. John 
Rogers, junior, Vine Lodge, Sevenoaks, who had imported 
the bulb. Mr. Rogers, who called Professor Lindley's 
attention to the character of the leaf -sheaths, remarked 
that the innermost one, which surmounts the bulb, is 
entire, and resembles a Florence flask in shape, being 
about eight inches high, and two to three inches in 
diameter at the base, but only three-quarters of an inch 
wide at the throat, translucent or semi-transparent and 
containing about a third of a pint of water. The pitcher 
is generally full, all the rain and dew on the leaves being 
conducted into it ; this water appears to be absorbed by 

January-March, 1919. 



the plant because if not replenished it disappears more 
rapidly than evaporation would account for. Lindley 
at a later date reduced his Govenia lagenophora to his 
G. utriculata, a West Indian species, first described by 
Swartz as Cymbidium utriculatum, but it is now known 
that the Mexican and the West Indian plants are very 
distinct and easily discriminated by the features men- 
tioned by Mr. Rolfe. The original specimen of G. lageno- 
phora does not seem to have been preserved, but the 
letter from Mr. Rogers, accompanied by a sketch, is in 
the Lindley herbarium, and at a still later date Professor 
Lindley identified dried specimens collected by Hartweg 
on the Monte de la Virgin as being identical with 
Mr. Rogers' plant. Since then the species seems to 
have remained unknown until, in September. 1907, 
Mr. Juan Balme, of Hijo, Mexico, sent a sketch of an 
orchid, collected in the State of Vera Cruz, along with a 
living bulb. The latter produced flowers in the Kew 
collection in 1908, and at last enabled the confusion 
between G. lagenophora and G. utriculata to be settled. 
Mr. Balme' s plant has been grown in a warm house, and 
is given an abundant supply of water except when the 
leaves die down. Under this treatment it has flowered 
on several occasions since 1908 ; our drawing was pre- 
pared when it did so in November, 1916. At the time 
of flowering the characteristic utricle does not appear to 
be fully developed.

Deutzia compaeta was sent to Kew by the late 
Mr. Maurice L. de Vilmorin in 1912, under the number 
4377. It was received with a batch of Chinese plants, but 
with no precise information as to the particular district 
in China from which it had been introduced, or by whom 
its introduction had been effected. It flowered at Kew 
in July, 1913, when the accompanying figure was pre- 
pared. At the same time flowering specimens were 
received from Glasnevin, gathered from a plant which had 
been presented to that establishment by Mr. de Vilmorin 
also. The Kew plant is now about 4 ft. high, bushy, 
and evidently very hardy. It is about the latest of the 
Deutzias to open its flowers, and this not only adds to 
its value as blossoming at a season when shrubs in flower 

January-March, 1919, 



are becoming scarce, but also enables it to escape the 
late frosts which, at Kew at any rate, almost every year 
ruin the display of most of the species. Its flowers are 
pretty and distinct in their compact arrangement, their 
small size and large numbers, characters which dis- 
tinguish it from D. ruben.s, Render. The Deutzias enjoy 
a good loamy soil and abundant sunshine, and are easily 
increased by means of cuttings put in in July. 

Distribution.— Shrub, probably 5-6 feet high, of bushy habit ; young shoots 
terete, furnished densely with stellate pubescence ; bark becoming dark brown 
and peeling the second season. Leaves oblong-lanceolate, acuminate, rounded 
at the base, finely serrate, those of the barren shoots 3 in. long, 1| in. wide, 
those of the flowering twigs f-l| in. long; conspicuously nerved, the chief 
lateral nerves 5-9 along each side the midrib, impressed above, prominently 
raised beneath; dull dark green above with scattered stellate hairs, paler 
beneath and almost covered with minute, 5-8-rayed stellate hairs ; petiole T V-J 
in. long, grooved on the upper side. Corymbs terminal on short leafy twigs* 
rounded, compact, many-flowered, about 2 in. across. Flowers J-f in. wide ; 
peduncle and pedicels scurfy. Beceptacle campanulate, Jj in. long. Btpah 
y \ in. long, ciliolate, acute, clothed like the receptacle with minute adpressed 
stellate scales. Petals imbricate, orbicular, } in. in diameter, white tinged 
with pink when young. Stamens 10, 2-seriate, shorter than the petals ; the 
filaments white, those of the outer row diverging at the top into a pointed wing 
at each side of the anthers, those of the inner row shorter; anthers at first red, 
then brown. Styles 3, glabrous. Fruit nor seen.

The charming little Primula here figured was raised at 
Kewfrom seeds collected by Mr. R. E. Cooper in Bhutan 
in the Eastern Himalaya for Messrs. Bees, Limited, by 
whom their supply was shared with this establishment 
in 1915. The species, which was for the first time 
described as P. tibetica by Sir George Watt in 1882, is a 
native of alpine Sikkim and Bhutan at elevations of 
16-17,000 feet above sea-level, and of the adjacent 
provinces of south-eastern Tibet. It was originally 
discovered by Sir J. D. Hooker, now seventy years ago, 
on the Sikkim frontier of Tibet. It bears a rather close 
resemblance to the more northern P. sibirica, Jacq., in 
which species, however, the scape is usually much longer 
and stouter, while the pedicels are shorter and the 

January- March, 1919. 



calyx-lobes have a fringe of minute glandular hairs that 
is absent from P. tibetica. Distinctive features of this 
Himalayan species are the pronounced yellow " eye " and 
the gibbous bracts. At Kew P. tibetica has proved 
hardy and has thriven well in the Rock-garden, but like 
so many other members of the genus it proves in culti- 
vation to be monocarpic and dies after flowering and 
ripening its seeds.

fibrous, pale straw-coloured roots. Leaves many, all radical, long-stalked, 
ovate-spathulate, rather rounded at the apex ; lamina f-f in. long, -|-f in. wide, 
papery, glabrous on both sides ; pale green, with 3-4 lateral nerves ; petiole

The striking Orchid here figured is one of the largest 
flowered members of the genus Liparis. It is a native 
of the island of Formosa where it was first discovered, 
over twenty years ago, on Liko Hill, near Tamsui, by 
Mr. H. B. Morse, of the Chinese Consular Service. The 
upper portion of the raceme of Mr. Morse's original 
specimen, which was communicated to Kew by Professor 
A. Henry, had been lost; a single flower, however, 
remained attached to the base of the inflorescence, and 
thus admitted of the preparation of a description of the 
species, as L. macrantha. The plant was met with again 
by Mr. H. J. Elwes in the low country near Taikow in 
Formosa, and a living specimen brought by him to 
England flowered for the first time in his collection at 
Colesborne, Cheltenham, in February, 1916. From this 
plant, which was then presented to Kew by Mr. Elwes, 

April-June, 1919. 



the plate now given has been prepared. The species 
belongs to the section MolliaefoUae, and is a striking 
plant on account of its large undulate leaves, its long 
raceme of vinous-purple flowers, and its large lip which 
is strongly toothed on the margin. At Kew L. macrantha 
has thriven well in a tropical Orchid House under the 
conditions and treatment suitable for Indian species of 
Lalantke.

Of the genus Pyrus as conceived by Linnaeus and 
adopted by Bentham and Hooker, the section Malus, or 
the crabs, is poorly represented on the continent of 
North America, some four or five species only being 
found there ; the pears (Pyrophorum) are not represented 
at all. Malus rivularis is the only crab found west of 
April-June, 1919. 



the Kocky Mountains where, however, it extends over 
many degrees of latitude, reaching from Alaska through 
British Columbia, Oregon and Washington to California. 
It belongs to the same group of crabs as M. ToHngo, 
Sieb. and M. Sargentii, Rehd., figured at t. 8757 of this 
work, all characterised by the calyx falling away from 
the apex of the fruit. From both the other species 
M. rivularis is well distinguished by its ellipsoid fruits 
and by the shorter lobes of the calyx as compared with 
the calyx- tube. The fruit has a rather pleasant acid 
flavour and is variable in size and colour. On our 
plant, which was obtained for Kew from a continental 
nursery in 1905, they appear to be larger and more 
cylindrical than is usual. According to Sargent this 
crab in a wild state affects moist situations where the 
soil is deep and rich, often forming in such places large 
impenetrable thickets. Archibald Menzies, the surgeon 
and botanist attached to Vancouver's expedition of 
survey, appears to have been the first European scientific 
observer to find it, which he did about 1793. David 
Douglas collected it some thirty years later, and it is 
said by Loudon to have been introduced in 1836. It 
has never been much cultivated in English gardens, 
although it is very hardy and grows vigorously, and is 
quite attractive when laden with its distinct and hand- 
some fruits. 

Description.— Tree, 15-30, sometimes 40 ft. high, the trunk 1-lj ft. in 
diameter ; young shoots clothed with grey hairs at first, becoming glabrous ; 
purplish-brown the second season. Leaves deciduous, ovate to ovate-lanceolate, 
aoute or acuminate, usually rounded or occasionally cuneate at the base, 
sometimes obscurely lobed above the middle, finely and sharply serrate; 
H-H in. long, -3-lu in. wide ; dark dull green, and at first puberulous above, 
finally glabrous ; paler and pubescent beneath ; petiole J-lJ in. long, pubescent. 
Flowers 3-1 in. wide, terminal or produced in the axils of the terminal leaves, 
8-12 forming a corymb 2-3 in. wide, expanding in May. Calyx-tube obconic, 
pubescent; lobes 5, lanceolate, r \ in. long, slightly pubescent or glabrous 
outside, thickly covered with pale grey wool within. Petals 5, orbicular with 
a short claw and a few jagged teeth near the base, ft in. long, creamy white. 
Stamens 16-20; filaments glabrous, flattened. Styles 2-5 (usually 3) joined 
near the base, glabrous. Fruit ovoid-oblong, pendulous, J-§ in. long, g in. 
wide, glabrous, ripe in October and then yellow tinged with pink on the sunny 
side, greenish in the shade, the calyx falling away and leaving a small pit at 
the apex; peduncles slender, 1-1 \ in. long, glabrescent. Seeds A in. long, 
pointed, compressed, pale brown, usually 3 in each fruit.

The genus Wittia is singular among the Cactaceae in 
combining with the habit of Phyllocactus and Epiphyllwn 
the character of possessing very small flowers. It was 
originally described by Dr. K. Schumann in 1911, and 
was based on a Peruvian species which he named 
W. amazonica; the plant in question was collected by 
Mr. Ule near Lacaitia and also near Tarapoto. The 
description of W. amazonica had just appeared when in 
October, 1911, a second species was met with by 
Mr. H. Pittier on the mountains above Chapo in Panama. 
This plant flowered at Washington some months after- 
wards and in due course was described and figured by 
Messrs. Britton and Rose as IV. panamensis. In 1914 
a plant of W. panamensis was presented to the Kew 
collection by Mr. D. Fairchild, Department of Agriculture, 
Washington. This plant, which has thriven well in the 
Succulent House at Kew, flowered there in May, 1917, 

April-June, 1919. 



when our figure was prepared. Since then Britton and 
Rose have been able to describe, as IV. costaricensis, 
yet another species, also collected by Pittier, but on 
this occasion on the west coast of Costa Rica. Britton 
and Rose also remark that Wittia is a strange genus, 
having stems resembling those of EpiphyUum and 
Rhipsalis, with flowers very different from those of 
either of these genera. 

Description.— Herb, with succulent, sparingly branched, elongated, flattened 
stems, which are leafy in appearance, are distantly crenate along the margin, 
exhibit a stout median rib, and attain a width of l£-ljin. Flowers axillary, 
borne at the bases of the crenations, 1-1} in. long, deep purple. Calyx with a 
rather slender tube about \ in. long, which is produced well beyond the ovary, 
and clothed at the base with a few minute scarious scales ; lobes 10, 2-seriate. 
erect, petaloid, oblong and blunt at the tip, those of the outer series faintly 
keeled, of the inner series rather longer and of thinner consistence. Petals 10, 
erect, oblong, apiculate, white, rather shorter than the sepals. Stamens many, 
included, lj-l^ in. long; filaments slender; anthers oblong. Style slightly 
exserted, slender, nearly J in. long; stigmas 4-5, nearly erect, oblong. 
Fruit ovoid, about f in. long, greenish-white or flesh-coloured.

The Honeysuckle here figured was originally discovered 
by the late Abbe Delavay in South-Western China, and 
was at first regarded by the late Mr. Franchet as a 
distinct species which he named in compliment to its 
distinguished collector. The more ample material now 
available has, however, led Mr. Render to think that it 
is only a glabrescent variety of Lonieera similis, Hemsl. 
The plant from which our figure has been prepared was 
presented to Kew in 1910 by the late Mr. M. L. de 
Vilmorin, who had raised plants at Les Barres from seeds 
received from South-Western China in 1901, some of 
which flowered for the first time in 1904. Among the 
nearer allies of L. similis, var. Delarayi, are L. macrantha, 
Wall., from which it differs in having a longer, glabrous 
corolla- tube, and L. longiflora, DC, from which it is 

April-June, 1919, 



easily distinguished by the leaves being grey-tomentellous 
beneath and cordate at the base. All three belong to 
the group Longi florae of the section defined as Nintooa by 
DeCandolle, within the subgenus Chamaeeerasus. A 
climber of vigorous growth, L. similis, var. Delavayi, is 
very hardy and, being evergreen, promises to be a useful 
addition to a group of shrubs rather scanty in outdoor 
collections —the hardy evergreen climbers. Another 
useful quality of our plant is the circumstance that it 
flowers as late as August. It thrives very well in a 
loamy soil and can be increased by late summer cuttings. 

Description.— Shrub, climbing, evergreen ; branches terete, glabrous. 
Leaves wide-lanceolate, acute at the apex and cordate at the base, up to 24 in. 
long and £ in. wide, entire, upper surface glabrous, with raised dots, bright green,

The pleasing Primula here figured is a native of the 
Eastern Himalaya, belonging to the Capitatae section of 
the genus, from all other members of which it is dis- 
tinguished by its doubly and rather coarsely toothed 
membranous leaves which are adpressed~ strigose- 
pubescent on both surfaces. It has been regarded by 
Sir George Watt as the East Himalayan representative 
of the well-known P. farinom, Linn., which extends from 
North America through Europe to Western Tibet. Our 
species was first discovered on Alpine slopes in Sikkim, 
at elevations of 13,000 feet, by one of the native 
collectors employed by Sir George King, who, recognising 
it as distinct, gave it the name P. bellidifolia, The plant

from which our figure has been prepared was one of a 
number raised from seed presented to Kew in 1915 by 
Messrs. Bees, Limited, for whom it had been collected in 
Alpine Bhutan in 1914 by Mr. R. E. Cooper. The species 
has thriven well at Kew, and plants put out of doors in 
the Rock Garden flowered freely in May. Other plants 
grown in pots in a cool frame flowered equally freely and 
were exhibited in the Alpine House. Like its allies 
P. farinosa, Linn., and P. denticulate, Sm., between which 
it is in general features intermediate, P. bellidifolia has 
proved monocarpic. The plants in this instance, how- 
ever, though behaving as if quite hardy, unfortunately 
died after flowering without ripening their seed.

The Rhododendron now figured was first met with by 
the Abbe Delavay, between 1883 and 1885, on the 
mountain Tsang-chan, overlooking Tali in Yunnan, at 
about 6,700 feet above sea-level, and was described by 
Mr. Franchet in 1886 as R. oleifolium. It was met with 
again in 1906 by Mr. George Forrest, on the eastern 
flank of the Tali range, Lat. 25° 40' N., in open alpine 
pastures at altitudes of 8-10,000 feet, as a dwarf shrublet 
a foot, to two and a half feet high, with blossoms varying 
in colour from white to pale rose. The plant from which 
our illustration was made was raised at Kew under glass, 
from seed obtained from Messrs. Bees, Limited, early in 
1915. It flowered in May, 1917, when only two years old, 

April-June, 1919. 



thus sharing with R. racemosum, Franch., another Yunnan 
species already familiar owing to its suitability for culti- 
vation in masses in flower-beds, and already figured at 
t. 7301 of this work, the characteristic of producing its 
blossoms at a very early stage of its career. Another 
feature which R. oleifolium shares with its near ally 
R. racemosum is that rare character in Rhododendrons, 
the production of solitary axillary flowers. To this 
peculiarity is due the distinctive habit of these two 
species; their leaf-bearing buds as a consequence are 
always terminal, and a primary shoot, having once 
flowered, never branches again save when it has been 
injured. Although the particular plant of R. oleifolium 
now depicted was raised under the protection of a cold 
frame we believe the species may prove hardy, for other 
plants, grown out of doors, have shown no signs of 
tenderness as yet, though the species has not been 
sufficiently long in cultivation to admit of our judging 
how resistant to English weather conditions it may be 
as compared with its better known ally, R. racemosum. 
From that species R. oleifolium is readily distinguished 
by the longer and narrower leaves, and especially by the 
presence of a soft hairy indumentum on the outside of 
the corolla-tube as well as by the lepidote style.

Calanthe tricarinata is an old and well-known Orchid, 
which was first discovered by Wallich in Nepal in 1819. 
Since then it has been met with by various collectors in 
many other localities in the north-west Himalaya. In 
the "Flora of British India" its habitat is given as the 
temperate Himalaya, at elevations of 5000-9000 feet, 
from Kashmir to Nepal. Soon after this announcement, 
which was made in 1890, the species was found in 
Sikkim, by Pantling, at an elevation of 6000 feet, in the 
Lachen valley. But it had already been reported by 
Maximowicz to occur in grassy woods near Lake Conoma, 
in Japan, and it was from Japan that the species was 
first introduced to cultivation in this country. This 
introduction was in a sense accidental ; the species was 
found among some plants of C. Textorii, Miq., imported 

April-June, 1919. 



by Messrs. J. Veitch and Sons in 1870. Between the 
time of its discovery in Japan and of its being met with 
in Sikkim, Mr. A. Henry had collected C. tricarinata in 
the northern mountain forests of Yunnan at an elevation 
of 7000 feet. In cultivation C. tricarinata thrives well 
under the conditions suitable for other species of the 
genus, such as C. Masttca, Lindl., figured at t. 4541 of 
this work. The plant now figured flowered in April, 
1916, in the collection of Mr. H. J. Elwes, at Colesborne 
Park, Gloucestershire, and was afterwards presented by 
Mr. Elwes to Kew. It is understood that this particular 
plant was obtained by Mr. Elwes from Sikkim. In 
spite of its wide distribution and of its introduction 
forty years ago, C. tricarinata has always been a rare 
plant in cultivation. It has, however, been used as one 
of the parents of a garden hybrid, C. Harryana, raised 
by Messrs. Veitch, the other parent in this case being 
C. Masuca. 

Description.— Herb, terrestrial ; pseudobulbs short, ovoid. Leaves 2-8, 
pctiolerl, elliptic or lanceolate-elliptic, somewhat acute, plicate, 7-12 in. long, 
2£-8| in. wide, slightly narrowed at the base. Scapes erect, 12-20 in. long;

The plant here figured was originally described as a 
variety of Lonicera hispida, Pall., but the characters 
given above seem to be sufficiently definite and constant 
to separate it from that very variable species. Following 
the classification of Rehder, this species, which he terms 
L. cliaetocarpa, is to be included in the Bracteatae group 
recognised by Hooker and T. Thomson within the 
section defined as Isika by DeCandolle, and thus falls 
within the subgenus which Linnaeus termed Chamae- 
cerasus. The original specimens of L. cliaetocarpa were 
collected in Kansu, but the plant has since been met 
with both in Szechuan and in Eastern Tibet. It was 
introduced to cultivation by Mr. E. H. Wilson in 1904 
when collecting in Western China for Messrs. Veitch, and 

April- Jdnb, 1919. 



the material from which our figure has been prepared was 
taken from a plant purchased from that firm in 1913. 
The Kew example is now a shrub about five feet high, 
of neat, rounded habit, and is evidently perfectly 
hardy. At Kew it is, indeed, regarded as one of the 
best and most satisfactory of the newer shrubby honey- 
suckles. It likes a good loamy soil and is easily 
increased by means of cuttings put in sandy soil in 
gentle heat during July and August. Its flowers open in 
early June and are of a pleasing primrose yellow. 

Description.— Shrub, compact in habit, about 5 ft. high ; branches terete, 
the younger purplish, hirsute with spreading hairs. Leaves oblong-elliptic, 
with an obtuse or sub-acute apex, rounded and often unequal at the base, 
li-2 in. long, about 1 in. broad, entire, the upper surface bright green, more or 
less hirsute, with the midrib and lateral nerves slightly impressed, the lower

The Desmodium now figured is a native of South- 
western China first gathered over thirty years ago by 
the Abbe' Delavay, by whom it is reported to occur on 
chalky hills near Lankong in Yunnan. It was first 
described from material sent by Delavay to Paris. Later 
it was met with by Mr. A. E. Pratt near Ta-chienlu in 
Szechuan, and a few years ago it was found again by 
Mr. G. Forrest on the eastern flanks of the Li-Kiang 
Range in Yunnan at elevations of 9-10,000 feet above 
the sea. The nearest ally of D. cinerascens is the North 
Indian species T). tiliaefolium, G. Don, a species of which 
we have as yet seen no Chinese example. The record of 
D. tiliaefolium as a native of China has been made in the 

April-June, 1919. 



" Plantae Wilsonianae " (pars iv. p. 104) ; but the plant 
so named appears to Mr. Hutchinson to be D. cinerascens 
or some nearly allied species, rather than true D. tiliae- 
folium, which has in India been associated with D. nutans, 
Wall., and D. argenteum, Wall., but is considered by Mr. 
Hutchinson to be distinct from both. From D. tiliae- 
folium, as thus restricted, Mr. Hutchinson separates 
D. cinerascens by its shorter petioles, more rounded 
leaflets, persistent stipules and usually quite simple pilose 
racemes. D. cinerascens appears to have been first raised 
in Europe from Chinese seeds by the late Mr. M. L. de 
Vilmorin in 1896. It was presented to the Kew collection 
by him in 1907, and has proved to be quite hardy, being 
now a bush three to four feet high. It does not flower 
until late in the year, usually in October, and while this 
adds to its value in places where the climate is sufficiently 
dry and sunny to enable the flowers to develop fully, 
in a locality like Kew they are apt to decay prematurely 
through lack of sunshine and excessive humidity. For 
the same reason seed can rarely ripen, and the plant 
must be increased by late summer cuttings. The 
material for our plate we owe to Miss Willmott, in whose 
collection at Warley Place plants raised from Chinese 
seed collected by Mr. E. H. Wilson have grown well.

This variety of the widely distributed Ipomoea Pes- 
tigridis is a new introduction to cultivation. The Kew 
plant which furnished the material for the figure was 
raised from seeds received in February, 1917, from 
Major Howard of Richmond, Surrey, who collected 
them, and also those of /. dasysperma, Jacq., figured at 
t. 8788 of- this work, at Kilimatinde in the district of 
Ugogo, East Tropical Africa, near the railway connecting 
Daressalam with Tabora. It had previously been found 

April-June, 1919. 



in other localities of the territory known as German 
East Africa ; it is also recorded from Somaliland and 
British East Africa. Grown in a warm house, it flowered 
while still quite a small plant in April, 1918, and, being 
an annual, has since died. Typical 7. Pes-tigridis ranges 
throughout India, where it is said to be common, growing 
in sandy soils ; it also occurs in Ceylon, the Malay 
Peninsula, Malay Islands, Polynesia, China, Mauritius, 
and in many localities in Tropical East Africa, extending 
from Kordofan in the north to the Zambesi in the south ; 
it is represented in Angola by the variety strigosa, Hallier 
f. Though of little merit as a garden plant it has 
appeared in cultivation from time to time, and is 
recorded as having been first introduced in 1732, the 
year of publication of Dillenius's Hortus Elthamensis, 
in which work (t. 318, fig. 411) it is figured as Volubilis 
zeylanica, Pes-tigrinw dicta. It is also figured in Rheede's 
Hortus Malabaricus, vol. xi. t. 59, under the name of 
Pulli-Schovadi. This Ipomoea belongs to the section 
Cephalanthae, the species of which usually have rather 
small flowers arranged in dense bracteate heads, with 
narrow herbaceous sepals more or less resembling the 
bracts. 

Description.— Herb, annual, everywhere densely beset with long yellow 
Btifi hairs. Stem twining, slender, 6 ft. long or longer. Leaves stalked, 
palmately 5-9-partite, 3-4i in. wide with rounded sinuses ; lobes lanceolate or

The Disporum now figured is a native of Western 
Hupeh, where it was first met with by Mr. E. H. Wilson. 
The plant from which our plate has been prepared 
flowered in 1917 in the collection of Miss E. A. Willmott, 
Warley Place, where seeds obtained by Wilson had been 
received from the Arnold Arboretum. Only one of these 
seeds, we learn from Miss Wilmott, germinated in her 
garden. The resulting plant throve well in good sandy 
loam in a sheltered and partially shaded border with a 
south-western exposure. A few flowers only were 
produced during the first season after planting out; 
since then, however, the plant has flowered freely each 
year and has ripened seeds well, thus admitting of ready 
propagation. Care has, however, to be taken to protect 
the ripening fruits against attack by birds. The genus 
Disporum was based by Salisbury in 1812 on a Chinese 
plant, Disporum pullum, which had been already de- 

Apkil-Jone, 1919. 



scribed at t. 916 of the," Botanical Magazine " as Uvularia 
chinensis, Ker-Gawl., and the plant now figured, though it 
differs sufficiently from the original type of D. pullum 
to deserve a separate plate, hardly merits, in the present 
state of our knowledge, the status of a distinct species. 
Sir Joseph Hooker has referred in the " Flora of British 
India " to the difficulty met with in the discrimination, 
from herbarium material alone, of the various forms that 
occur in the genus Disporum. In the case of those forms 
generally included in D. pullum this difficulty is especially 
great, and this species, as now understood, contains a 
number of more or less distinct states differing from each 
other in the width and degree of pubescence of the 
leaves, the length of the peduncle, the size of the flower, 
and the colour of the perianth-segments which varies 
from white to deep-purple. In the form here figured 
there is another marked distinction; the perianth- 
segments, instead of being straight, at length spread 
steliately towards their tips. For this reason it is now 
provisionally accorded the rank of a distinct variety, 
whose name, hrunnea, is derived from the circumstance 
that these segments are of the purplish-brown colour 
indicated at n. 72 of the " Code des Couleurs " of Messrs. 
Klincksieck and Valette.

The red Belvidere, also termed the Summer Cypress 
or Mock Cypress, here figured, is generally accepted as 
a cultivated condition of Kochia scoparia, Schrad., a 
Chenopodiaceous plant which extends from temperate 

July-September, 1919. 



Asia westward through central and south-western Russia 
to Hungary. Throughout Germany as far as the Nether- 
lands and from Central Europe southwards into the 
Balkan peninsula, Italy and southern France, it also 
occurs not infrequently as an alien. The name scoparia, 
long associated with the species, reflects the fact that 
throughout southern Europe the dry plant is used for 
making brooms. The genuine Kochia scoparia has been 
known in English gardens at least since the close of the 
sixteenth century ; it was figured by Gerarde in 1597 
as the Bushie or Besome Tode-flax, but he was already 
acquainted with the popular Italian name Belvidere, 
which during the seventeenth century appears to have 
been the term mostly used in English and French 
gardens. It is clear from Gerarde's account that the 
form of the plant known to him did not change in colour 
from green to red during the autumn, and, indeed, there 
is no evidence that during the next three centuries any 
form of K. scoparia exhibiting this phenomenon was 
known to gardeners. Nor is there any indication that 
during the sixteenth and seventeenth centuries the form 
of the Belvidere with narrower leaves figured in our plate 
was in cultivation in this country. We do not till 1759 
find any evidence that suggests the existence of 
K. scoparia, forma trichophila, in British gardens. This 
evidence comes from Scotland, and the seed of the 
narrow-leaved form appears to have arrived there from 
Holland as Belvidere, under which name it appears in 
a Haarlem seed-list of 1754. We learn from Miller's 
"Gardeners' Dictionary" of 1768 that the narrow- 
leaved form was in English gardens, but we find no 
allusion to any save a green Belvidere throughout the 
eighteenth century. With the establishment of the form 
with nearly filiform leaves just after the middle of that 
century, the cultivation of the true K. scoparia appears 
to have been abandoned. During the later half of the 
nineteenth century the same became very nearly the 
case as regards the green narrow-leaved form, its culti- 
vation being continued only in large establishments 
like that at Kew. At the close of the century, however, 
interest in this old-fashioned plant became resuscitated 
owing to the discovery in or shortly before 1898 of the 



red Belvidere, which we now figure. In that year a 
farmer from Alleghany, Pennsylvania, visiting Riverton, 
New Jersey, handed to Mr. J. W. E. Tracy some seed of 
this plant with the information that it had been collected 
from a wild specimen found growing in the woods near 
Alleghany. The seed was made over to Mr. Henry A. 
Dreer, who grew it, but did not, however, take the plant 
up. In the following year seed was made over to Mr. 
Burpee who gave the plant a trial, and placed it in his 
catalogue for the first time in 1900. Mr. A. J. Pieters, 
of Washington, to whom horticulture is obliged for this 
information, remarked in 1906 that after having grown 
the plant for four years, he had found it constant as 
regards the change of colour which is its most striking 
characteristic, but that it is apt, when checked in its 
growth, to revert to the opener habit which marks the 
true K. scoparia. It is interesting to note that shortly 
after the record of this experience by Mr. Pieters, 
Professor Beck was in a position to describe for the first 
time in Reichenbach's " Icones " (vol. xxiv. p. 154 : 
1908) a blood-red wild form as K. scoparia, forma 
sanguinea. For the introduction of the red Belvidere 
with filiform leaves to this country we are indebted to 
Messrs. Cannell and Sons, Swanley, who first brought 
it to notice in the autumn of 1901. Although the fact 
is not on record, it is probable that their seed may have 
come from the United States. The red Belvidere is now 
somewhat extensively used as a summer bedding plant 
in gardens, a purpose for which it is well suited. It 
comes true to seed, and the change in colour from bright 
green to magenta red takes place somewhat suddenly 
in autumn. The change appears to mark a stage in 
ripening, and to be unconnected with the climatic con- 
ditions encountered by the plant whether in this country 
or in North America. 

Description. — Herb, annual, polygamous, much branched from the base, 
very leafy; crown globose, oblong or conic-pyramidal. 1-i— 5 ft. in height; 
branches and branchlets virgate. erect, at first thinly pubescent, soon nearly 
glabrous, though often laxly woolly towards the top and especially at the nodes. 
Leaves narrow linear or the uppermost nearly filiform, acute, the longest over 
\ in. long, \ in. or less wide, glabrous or the uppermost somewhat ciliate. all 
white-punctate. Flowers in threes or pairs, or solitary, ses3ile in the axils of the 
upper leaves, often surrounded at the base with loose wool, some female, some 



2-sexual. Perianth urceolatc, 5-lobcd, membranous, the female rather depressed, 
glabrous except the lobes, which are ciliolate, inflexed and hood-like, somewhat 
apieulate and traversed along the back by a green blunt keel, when ripe little 
altered save that the keel is occasionally enlarged in the middle into a thick 
transverse wing. Anthers purple. Ovary ovoid ; style very short ; stigmas 2. 
Fruit depressed, lenticular. Pericarp and testa membranous. Embryo horizontal.

The interesting Odontoglossum now figured is a native 
of Ecuador, where it was first discovered about eighty 
years ago by Mr. T. Hartweg, when collecting plants for 
the Royal Horticultural Society of London. The locality 
of the original specimens was Mount Paccha, near Loxa 
on the western slopes of the Andes opposite the Gulf 
of Guayaquil. For many years this species, which 
Lindley had described as 0. cristatum, was only known 
from the original herbarium specimens, but m 184/ 
living plants of an Odontoglossum, collected in the Loxa 
district bv Mr. G. Wallis, were sent to the horticu tural 
establishment of Mr. Linden at Brussels ; these plants, 
on flowering, were recognised as identical with Hartweg s 
one. At a later date the late Mr. Consul Lehmann 



July-September, 1910. 



/ 

obtained other specimens of this species in Ecuador, in 
the forests of Pacayurcu, above Zaruma, also above 
Ayabamba and Paccha, at from 4,500-6,800 feet above 
sea-level. Though never a common species in cultiva- 
tion, it is usually present in representative collections 
of Orchidaceous plants. The figure here given has been 
prepared from an example which flowered in the Royal 
Botanic Garden, Glasnevin, in March, 19.17. 

This plant, Sir F. Moore informs us, was presented to 
the Glasnevin collection by Sir Jeremiah Colman, in 1908, 
who had grown it at Gatton Park as an unnamed Odonto- 
glossum. The species thrives under the treatment for 
cool-house orchids, a minimum night temperature of 
50° F. in winter, with cool airy conditions in summer. 
A more slender plant in every way than the familiar 
O. crispum, Lindl., from New Grenada, O. cristatum 
makes finer and more delicate roots, so that care should 
be taken that the potting material is not too coarse. 
There is at Glasnevin another example of 0. cristatum, 
obtained in 1893 from Mr. Cowan, of Gateacre, which 
was identified at Kew on its first flowering in 1894. 
The nearest ally of 0. cristatum is O. Hallii, Lindl., 
another Ecuador Odontoglossum, which has been already 
figured at t. 6237 of this work.

The plant from which our plate of Abelia longiflora 
has been prepared was presented to the Kew collection 
by Sir John Ross of Bladensburg, in 1915. The species 
is a native of China, and the specimens on which the 
original description of Dr. Render was based were col- 
lected in the district of Ichang, in the province of Hupeh, 
by Mr. A. Henry. These original specimens differ in 
certain minor particulars from the cultivated plant here 
represented. The wild plant has all the twigs, young 
and old, nearly or quite glabrous, whereas in our plant 
the young twigs are densely clothed with short spreading 
hairs. The corolla in the original specimens collected 
by Henry are somewhat larger than in the plant received 

July-September, 1919. 



at Kew from the collection at Rostrevor. The nearest 
ally of A. longituba is A. uniflora, R.Br., another Chinese 
species figured at t. 4694 of this work. Both species 
have heen placed by Render in the section Euabelia 
and in Graebner's sub-section Vniflorae. There is, indeed, 
room for doubt as to whether A. longituba be really more 
than a variety of Brown's species. From the horti- 
cultural point of view, however, A. longituba is suffi- 
ciently distinct from the older species to warrant the 
publication of a special plate. At present the Kew plant 
is a dwarf shrub which flowers most copiously during the 
latter part of the summer, a circumstance that makes 
it a very welcome addition to cultivated hardy shrubs. 
It is perfectly hardy, grows well in loamy soil, and is 
easily propagated by means of cuttings put in gentle 
heat in July or August. 

Description. — Shrub, branches slender, the older twigs dark and glabrous or 
slightly puberulous, the younger purple and densely puberulous. Leaves ovate, 
elliptic-ovate or oblong-lanceolate with a rather obtuse and mucronulate apex, 
the base more or less cuneate, j}-l in. long, -j-i in. wide, margin entire or 
slightly serrulate, upper surface bright green, glabrous except for the eiliate 
margins, lower pale, white-villose along the mid-rib, especially in the lower 
part ; petioles up to i in. long, slightly hirsute. Peduncles 1 -flowered, axillary, 
situated near the ends of short branches, ^\ in. long, with 2 subulate-linear 
ciliolate bracts in the middle and 4 ovate 'ciliolate bracteoles at the apex. 
Receptacle, (ovary) cylindric, about i in. long, $ in. in diameter, slightly 
puberulous. Sepals 2, oblong- elliptic, obtuse, up to $ in. long, £ in. broad, slightly 
ciliolate, nearly glabrous. Corolla infundibuliform, from nearly 1 in. to H in. 
in length, tubular below the middle and ventricose on one side at the extreme 
base, enlarged from the middle upwards, limb spreading, 5-lobed, lobes sub- 
orbicular, | in. long and broad, minutely glandular-pubenilous outside, throat 
on the inside beset with long distinct hairs. Stamens 4, filaments nearly § in.

This fine Wistaria, Messrs. Render and Wilson have 
pointed out, is readily distinguished among its congeners 
by the persistent soft and short indumentum of the 
leaves, by its comparatively short and very wide racemes, 
its stout spreading velvety pedicels, its large flowers, 
and its long subulate anterior calyx-teeth. When the 
number and character of these distinguishing features 
are considered it seems extraordinary that the right of 
the Japanese W. venusta to be regarded as a species 
apart has remained so long unrecognised. In addition 

July-September, 1919, 



to the citations which accompany our description, the 
authors quoted supply others, which it is needless to 
repeat here ; it is sufficient to remark that it has been 
confused more than once with the common W. sinensis, 
Sweet, and the not unfamiliar W. brachybotrys, Sieb. & 
Zucc. It was first seen in this country under the latter 
name, in the Japanese section of the International 
Horticultural Exhibition held at Chelsea in May, 1912, 
and in the following year was acquired from a Yokohama 
nursery for the Kew collection. According to Mr. 
Wilson, W. venusta is cultivated here and there in temple 
gardens in Japan as the " Shira-fudzi," or White 
Wistaria ; but the colour of the flowers would appear to 
vary, for a specimen collected by Mr. R. Oldham, " wild 
on hills near Nagasaki," in 1863, which undoubtedly 
belongs to this species, is noted by him as having bluish- 
violet flowers. The plants exhibited in 1912 were 
shown as shrubs grown in vases ; in the Kew collection, 
however, it thrives quite well in the open, and flowers 
annually in May and June. It makes a very welcome 
and beautiful addition to the popular group of hardy 
flowering climbers and, like other members of the genus, 
requires a good rich soil and the sunniest position 
available. The flowers are frequently more or less 
" double." 

Description. — Shriib, climbing ; final shoots drying purplish-black, glabrous 
in their second year ; bud-scales wide-ovate, mucronate, the outer about £ in. 
long and wide, firmly papery, brown, glabrous with finely ciliolate margins, the

Iris Beichenbachii is a native of the Balkan countries 
from Bosnia, southern Hungary and Serbia, to eastern 
Rumelia and southern Macedonia. The species was 
originally described by HeufTel from specimens found in 
the Hungarian Banat, growing on rocks by the Danube, 
and from others gathered near Herkulesbad. It may be 
regarded as the Balkan representative of the more 
western species /. Chamaeiris, Bert., a native of Italy 
and southern France, from which /. Beichenbachii is 
easily distinguished in the living state by the very 
acutely keeled herbaceous spathes. While in reality an 
extremely natural species, /. Beichenbachii is at the same 
time characterised by extraordinary variability in size 
of plant and colour of flowers. Owing to this variability 
the plant has at times been misunderstood, hence the 
unusually long list of synonyms. How pardonable this 
misunderstanding is will be readily appreciated from an 
examination of our figure. /. Beichenbachii has been 
in cultivation in the Iris collection at Kew since 1904, 
when a supply of plants was acquired from Messrs. Haage 
and Schmidt, Erfurt. Additional plants were presented 
to Kew by the Hon. N. C. Rothschild in July, 1915 ; 
these had been collected on the mountains near Conrova, 
in Bulgaria. Yet other plants were presented to the 
national collection by Lady Muriel Herbert in May, 1919 ; 
these had come from Salonika. The plate now published 
has been based, however, on other material ; the form 
with red-purple flowers was received from Miss D. 
Blanchard, who had flowered it in her garden at Park- 
stone, Dorset, in May, 1919— her plants having originally 
been received from Macedonia ; the form with greenish- 
yellow flowers was sent by Lady Muriel Herbert in May, 
1917— it was one of her plants from Salonika. At Kew, 
1. Beichenbachii is quite hardy, and has flowered in an 
open border. It prefers, however, a warm position 
against a wall. Seeds are only sparingly produced, but it 
is easily propagated by division of the root stock, as in 
most other species of the section to which it belongs. 

Description-.— Herb, with a rootstoek £ in. thick. Leaves densely clustered, 
ensate, more or less falcate, those of the sterile chimps :it length usually 5-6 in. 
long and i-fin. wide, hut at times much longer and wider, those of the tWerinc; 
stem shorter, glaucous-green, smooth. Stem 4-6 in., occasionally as much as 



10 in. high, 1-2-foliatc below, closely 2-flowered at the apex. Sjyathes herbaceous, 
green, Avidc oblong-lanceolate or elliptic-lanceolate, acuminate, very acutely 
keeled, l|-2in. long. Pedicel very short. Perianth with the tube greenish 
or upwards somewhat flushed or blotched with purple, 1-1J in. long, shorter than 
or at the most equalling the spathes ; outer segments with a reflexed elliptic or 
obovate limb, 1^-lf in. long, £— 1 in. wide, yellowish but suffused with purple 
towards the margin and with a yellow crest, or lurid purple throughout and then 
with a bright blue crest ; claw narrowly cuneate, j— 1 in. long, with rather pah- 
purple veins ; inner segments erect, the lamina bluntly elliptic or obovate, 
suddenly or less often gradually contracted into a red-blotched claw, including 
the claw l}-2£ in. long, 1-lj in. wide, of the same colour as the outer segments. 
but rather more vivid. Anthers rather shorter than the filaments. Omni 
oblong, |-f- in. long ; style-arms wide oblong, pale purple or yellowish ; lobes 
of the crest obliquely ovate, toothed.

The Delphinium here figured was first met with in 
1872 by Przewalski on the Kansu border, on the mountains 
just south of the Tetung River. It was first flowered in 
the Botanic Garden at Petrograd in 1876 from seed 
communicated by Przewalski, and was named by 
Maximo wicz D. Pylzowii, in honour of Przewalski' s 
travelling companion, M. A. Pylzow. Przewalski gathered 
the species again in 1880 at elevations of 9,000 to 11,000 
feet, between Kuku-Nor and the Tetung, and it has since 

July-September, 1919. 



then been found by Wilson near Sun-tang, in the Si-fan 
region of north-western Szechuan, as well as by Farrer 
in Kansu. From Farcer' s indication, " On the Eaves 
of the World," vol. ii. p. 186, his locality is in the Min- 
Shan range, somewhat to the north-east of Wilson's 
collecting ground. Our figure has been prepared from 
a plant presented to Kew by Mr. Farrer in June, 1917. 
Of two plants then received, one was grown in the Rock 
Garden, the other kept in a pot in a cold frame. The 
species has proved to be a hardy perennial, both plants 
flowering in May, 1918, when our drawing was made. 
Both plants produced good seed, and survived the winter 
following; both flowered again in May, 1919. The 
conditions most suitable for D. Pylzowii are those needed 
for the well-known D. grandiflorum, Linn. Although the 
dark azure-violet shown in our illustration appears +o 
be the normal colour of the flower, Maximowicz records 
the existence of a form with pale rose or rose-lilac 
blossoms.

The section Magnipuncta, recognised by Haworth within 
the large and polymorphic genus Mesembryanthemum, 
includes only two forms, the original M. magnipunctatum, 
Haw., and the one now figured, which Haworth at first 
was inclined to regard as only a variety of M. magni- 
punctatum, but at a later date treated as a distinct 
species, M. nobile. The original M. magnipunctatum was 
based on a plant collected by Burchell and cultivated 
at Kew nearly a century ago. There is a coloured drawing 
in the Herbarium collection of a flowerless example 
which was collected on the heights near the Zekoe River 
by Bowie in 1818. When Haworth indicated the exis- 
tence of the variety nobile, he tentatively referred to 
that variety the plant regarded by Prince Salm-Dyck 
as M. magnipunctatum, and this plant became the type 
of M. nobile, Haw., in 1823. There is at Kew a coloured 
drawing of Haworth' s second species which is noted 
as having been received from Prince Salm-Dyck, The 

July-Skptbmbir, 1919. 



plant shown in that drawing is again without blossom, 
but the species was afterwards figured in Salm-Dyck's 
monograph. Salm-Dyck obtained his plant in 1814 
from Vienna. Since then M. nobile has been collected at 
the Gamka River, Prince Albert Division, Cape Colony, 
by Zeyher, and, according to Berger, it has also been 
met with by Marloth in the adjacent Beaufort West 
Division. Plants both of M. magnipunctatum and M. 
nobile were presented to Kew in 1916 by Mr. Cecil 
Hanbury, from the La Mortola collection, and the figure 
of the latter now given has been prepared from the 
La Mortola example, which agrees well in its essential 
characters with those of Bowie and Salm-Dyck. The 
differences between the two allied species are well shown 
by the examples of each now grown at Kew, where they 
thrive well and flower in summer in a green-house. 

Description.— Herb, small and stemless. Leaves 4-6, connate at the base, 
spreading or slightly recurved, oblong, rather blunt, thick, flatfish above, slightly

The material for the accompanying figure of Rhodo- 
dendron dichroanthum we owe to the courtesy of Mr. J. C. 
Williams, in whose collection at Caerhays it flowered 
in May, 1918. The species is one discovered by Mr. G. 
Forrest in July, 1906, at altitudes of from 9,000 to 
11,000 feet above the sea, in shady situations of the 
open country on the eastern flank of the Tali Range, in 
western Yunnan, in 25° 40' N. Lat. Of two distinct 
gatherings of the species obtained in 1906 Forrest 
describes the corollas as being creamy rose or yellowish 
rose. The plant now figured had, however, purplish-red 
flowers, and Mr. Millais records the corolla of this species 

July-September, 1919. 



as being very variable in colour. Mr. Williams says with 
regard to this Rhododendron that perhaps sufficient is not 
yet known as to the most suitable situation, but in cases 
where a choice is possible it would be preferable, judging 
from its behaviour under conditions to which it has 
already been subjected, to select a cool damp slope with 
no overhead shade,' with an eastern aspect or one even 
to the north of east, but with at the same time shelter 
from wind. R. dichroanihum is closely allied to R. nerii- 
florum, Franch., figured at t. 8727 of this work, but is 
readily distinguished by the mealy hairy covering on 
the under surface of the leaves and by the puberulous 
filaments. Both species are remarkable for the presence 
of large outgrowths within the base of the corolla-tube. 

Descriptiox. — Shrub, evergreen ; year-old twigs glabrescent, about £ in. 
thick, with pale brown bark ; young shoots closely covered with a webbed white

The very handsome Primula here described is one 
of the discoveries of Mr. G. Forrest, by whom it was 
first collected in July. 1913, on the Chungtien plateau 
in Yunnan, 27° 55' N. Lat,, at about 12,000 to 13,000 
feet above sea-level, where it grows in open Alpine 
meadows. Seeds of P. chiwiantha were presented to 
Kew by Mr. J. C. Williams, of Caerhays Castle, Cornwall. 
in April, 1915, from the fruits of Mr. Forrest's collection 
of 1914 on the Mekong-Salwin divide, also in Yunnan. 
Seedlings were raised and planted in the Rock Garden 
at Kew, where they flowered in May, 1917, when our 
figure was prepared. The species has proved perfectly 
hardy at Kew, but, like all those belonging to the same 

July-September, 1919. 



group, died after flowering. Abundant good seed was, 
however, produced, and from this a further stock of 
plants has been raised. P. chionantha thrives best in 
a shady situation in moist rich soil. The species is 
compared by Professor Balfour with the Oriental and 
North Asian P. nivalis, Pallas. It differs from P. nivalis 
mainly in its nearly entire leaves, its constantly verti- 
cillate inflorescence, and its shorter calyx. It is also 
taller and more robust in habit. 

Description.— Herb, stout and mealy, 14-28 in. high. Leaves obovate- 
oblanceolate or oblong- elliptic, blunt, narrowed at the base into a veined winged 
petiole, up to 10 in. long and 2 in. wide, rather stout, finely repand- denticulate, 
without hairs, but sulphur-mealy on the under surface ; lateral nerves ascending, 
about ten on each side of the mid-rib, when dry raised beneath ; petiole up to 1 \ in.

This Brachystelma was first discovered near the Mooi 
River, Transvaal, by Joseph Burke, some time between 
1840 and 1842. It has since been collected in several 
other localities in the Transvaal, also in the Orange River 
Colony, Basutoland and Zululand. Tubers of the plant, 
collected near Pretoria, were sent to Kew in January, 
1917, by Mr. A. M. Bottomley of the Division of Botany, 
Pretoria, and from one of these the material for the figure 
was obtained in the following May. It is an interesting 
and curious plant, but scarcely ornamental, and its 
flowers, as is often the case in the family, have a very 
disagreeable odour. The tubers are eaten by the natives, 

July-September, 1919. 



and are known as Hottentot's bread : in the raw state they 
have a bitter taste. Several species of Bracki/stelma are, 
or have been, in cultivation ; these include B. tuberosum, 
R. Br. (t. 2343), B. crispum, Grah. (t. 3016), B. Barberiae, 
Harv. (t. 5607), and B. oianthum, Schlechter (t. 8670), 
which have been figured in this Magazine. The genus 
comprises about seventy-four species, of which forty-five 
are natives of South Africa, and nineteen of Tropical 
Africa ; there are several in India, one in Si am, and one 
in New Guinea. At Kew B. foetidum is cultivated in a 
dry tropical house devoted to succulent plants, where it 
flowered for the first time in August, 1918, when the 
figure now given was prepared. 

Description. — Herb with a perennial tuberous rootstock. Tuber flattened, 
up to 5 in. across. Stems solitary or several, ascending or spreading, branched, 
3-6 in. long, clothed with short spreading hairs. Leaves opposite, spreading, 
linear-lanceolate, lanceolate or elliptic, rarely obovate, tip acute or obtuse, 
margin sometimes undulate, narrowed at the base into a short petiole, villous 
on both surfaces or glabrous above, \-2 in. long, \- $ in. wide. Flowers axillary, 
solitary or often in clusters of 2-6, odour very disagreeable. Pedicels i-i in. 
long, pubescent. Sepals lanceolate, acute, J-4 in. long, pubescent. Corolla 
1-2 in. across, pubescent to nearly glabrous outside, glabrous or rarely puberulous 
within, limb dark-purple and yellow with the lobes greenish upwards, and the 
tube beset with tawny minute warts ; tube campanulate, ^-J in. long ; lobes free, 
spreading, linear or lanceolate from a deltoid base, acute, f-1 in. long, tjVtV in. 
wide, shortly ciliate. Outer corona cup-shaped, about as long as the staminal 
column, 10-toothed, so as to form small sacs alternating with the anthers ; the 
tooth themselves erect, deltoid, very short. Inner corona with linear, blunt, very 
short lobes incumbent on the backs of the anthers. Follicles geminate or solitary , 
fusiform-terete, bluntly beaked, pubescent, 2J-3J in. long, J-J in. wide.

Crataegus Wattiana belongs to Zabel's section San- 
guineae, a group of Central and North Asiatic thorns 
characterised by dark shining purplish-brown young 
shoots, and a calyx whose lobes are entire and shorter 
than the tube. It is closely allied to C. sanguined, Pall., 
with the yellow-fruited form of which it has been con- 
fused. The material for our figure was gathered from a 
tree purchased in 1900 from a continental nursery under 
the name " C. sanguinea, var. xanthocarpa." The forms 
of C. sanguinea are, however, to be distinguished by the 
invariably cuneate base of the leaf, the more or less 
pubescent foliage, and the pilose summit of the ovary. 
In C. Wattiana the leaves, especially on the barren 

July-September, 1919. 



twigs, are often truncate or even slightly cordate, the 
foliage is perfectly glabrous, as is also the summit of 
the ovary. The type specimen of C. Wattiana in the 
Kew Herbarium was collected by Mr. J. H. Lace in 1888 
in the Urak Gorge, Baluchistan, at 7,200 feet, and it 
was named three years later by Messrs. Hemsley and 
Lace in their paper on the vegetation of that country, 
published in the Journal of the Linnean Society. The 
name " altaica " first appeared in 1838 in Loudon's 
" Arboretum et Fruticetum Britannicum " (vol. ii. 
p. 823), where it is quoted as " C. altaica, Ledebour in 
Loddiges' Catalogue," and reduced to C. purpurea, 
var. altaica. In 1897 the name was taken up by Lange 
in the work cited above, but it is doubtful whether his 
plant and the one now figured be identical with that 
mentioned by Loudon as growing in the nursery of Messrs. 
Loddiges at Hackney in 1837. Even assuming its validity, 
Lange's name is superseded by Hemsley and Lace's older 
one. The greatest beauty of C. Wattiana is in August, when 
its fruits become ripe and acquire that clear and remarkably 
translucent yellow colour which makes them so distinct 
from the fruits of any other Crataegus we cultivate. 
The flesh is soft, and when once fully ripe the haws soon 
begin to fall from the branches. The tree at Kew is fifteen 
feet in height. 

Description.— Tree, probably not exceeding 20 ft. in height when full-grown, 
unarmed, with a lax spreading head of branches ; bark of trunk peeling ; young 
twigs dark brownish-purple, shining, glabrous ; winter-buds blunt and rounded, 
dark shining brown. Leaves deciduous, broadly ovate on the fertile shoots, 
triangular on the barren ones ; l£-4 in. long, 1£-3J in. wide ; apex acute, base 
broadly cuneate to truncate, margins with 3-5 pointed lobes at each side, 
sinuses occasionally reaching nearly to the mid-rib; petiole |-1 J in. long. 
Stipules arcuate, semi-cordate, £-1 in. long, foliaceous, jagged-serrate. Corymbs 
terminal on short leafy twigs, 2-3 in. across, many-flowered, each flower about 
j in. wide, white, opening in May ; pedicels glabrous. Calyx with an urceolate 
tube and 6 triangular-ovate acuminate glabrous lobes, shorter than the tube, 
reflexed after pollination. Petals white, orbicular, \ in. wide. Stamens 18-20 ; 
h laments glabrous ; anthers pale vellow. Ovary glabrous at the summit ; styles 
usually 5, glabrous. Fruit globose, J in. wide, clear translucent vellow ; flesh 
BOft ; pyrenes usually 8, hatchet-shaped, I in. long.

The genus Baikiaea was named in honour of the late 
Dr. William Balfour Baikie, of the Naval Medical Service, 
who was surgeon to the Niger Expedition of 1854 and 
did much to further our acquaintance with the vegetation 
of West Africa. The species now figured was first col- 
lected bv the late Mr. G. Mann in the island 01 Fernando 
Po in lb63, and described by Mr. Bentham as B. insignis 
in 1865 ; it has since then been met with on the African 
continent in Lagos, the Cameroons, and the French 
Gaboon. There is a closely allied species, B. minor, 

Octobek-Decembek, 1919. 



Oliv., which occurs in the Cameroons, the Congo State 
and Uganda, with smaller flowers and obtuse emarginate 
leaves. Other species, with much more numerous and 
quite small leaflets and flowers, are to be found in Angola 
and in the Zambesi basin. The flowers of B. insignis 
are probably the largest known in the suborder Caes- 
alpinieae of the family Lyuminome. The dorsal petal is 
distinctly coloured and exhibits the additional peculiarity 
of embracing the tenth, and quite free, stamen which it 
thus keeps apart from the remaining connate stamens, 
perhaps at a suitable time opening a door whereby birds 
or insects may obtain access to the nectaries. The 
plant whence the material for our figure has been 
obtained was received at Kew in 1894 from the Botanical 
Station, Lagos. It flowed for the first time in a tropical 
house in July, 1914. Planted in a border in this house 
it has grown to a height of thirty feet, and in July, 1918, 
it flowered more profusely than in previous years. The 
flowers are extremely fugacious and in size, texture and 
colour recall those of Camoensia maxima, figured at 
t. 75 ! 2 of this work, save that the vellow colour in the 
latter case, instead of being confined' to the dorsal petal, 
occurs as a marginal line on every petal.

The Polygonaceous shrub here figured was first met 
with in the Lebanon by La Billardit-re about the year 
1787, but was not described until 1844 when Jaubert 
and Spach named it Atraphaxis Billardieri in honour of 
its discoverer. The area of the species extends from 
eastern Greece to Asia Minor and Syria. It appears to 
be restricted to rather high elevations ; in Greece it does 
not occur under 2000 feet above sea-level ; in Crete it is 
only met with above 4500 feet ; in Asia Minor and the 
Antilibanon it begins at 4000-5000 feet. The Greek 
specimens of this Atraphaxis, collected by Zuccarini in 
Aetolia and Euboea, were described by Meisner as vari- 
etally distinct, but this author's var. graeca, apart from 

October-December, 1919. 



its occurrence at lower elevations, is distinguished mainly 
by the more attenuated, lanceolate and acute leaves, and 
subsequent authors have not recognised Meisner's variety. 
Another form, which has tetramerous flowers among the 
typically pentamerous ones, was described and figured 
by Jaubert and Spach (111. PI. Or. vol. ii. p. 13, t. 110) 
as A. variabilis, and regarded by them as a distinct 
section {Tragatraphaxis) of the Linnean genus. Boissier, 
however, regarded this form as only a variety (var! 
heterantha) of A. Billardieri, and it differs in no other 
character from the form represented in our plate, which 
has been prepared from a plant in the collection at Kew, 
obtained by purchase from Mr. F. Sundermann of 
Lindau in 1903. The only other representative of the 
genus Atraphaxis which occurs in Europe is the Crimean 
.4. tpinosa, Linn. In Asia, however, the genus ranges 
rather widely from Sinai, Syria, Asia Minor and the 
Caucasus over the whole of Iran and Central Asia to 
Lake Baikal. It is a distinctly xerophytic type and 
includes about a score of species, similar in habit, which, 
notwithstanding their inconspicuous flowers, produce a 
pleasing effect in the more or less arid regions they occupy 
owing to the charming coloration of the persistent and 
accrescent perianth-segments. This characteristic is well 
manifested in A Billardieri which, as grown on a slope

stigmate capitato 2-lobulato coronatus. — Primula delicata, G. Forrest in 
Notes Boy. Bot. Gard. Edinb. vol. xix. p. 222 (1908).— J. HoTGHlNSOK. 



The pleasing Primula now figured was first collected 
by the late Abbe Delavay in June, 1884, en Mount 
Tseng-chan, near Tali, in Western Yunnan, at about 
7000 feet elevation. A year later it was described as 
P. spicata by the late Mr. Franchet. A member of the 
section Soldanelloides, this species is distinguished within 
that group by its loosely spicate flowers ; in other 
species of the section the flowers are usually capitate. 
Except in this particular P. spicata most resembles 
P. chasmophila, Balf. f., figured at t. 8791 of this work. 
During September and October, 1906, P. spicata was 

October-December, 1919. 



collected again at the rather higher altitude of 11,000 
feet, by Mr. G. Forrest, on dry rocky slopes and ledges 
of cliffs in side valleys on the eastern flank of the Tali 
range. In August of the same year Forrest had 
gathered a smaller plant in the same neighbourhood. 
This the collector described as P. deticata, but it is now 
known that P. delicata, Forrest, is only a diminutive 
form of P. spicata. A decade later, seeds of P. spicata 
were collected on the Tali range by Mr. Forrest, and 
from these plants were raised by Messrs. Wallace, of 
Colchester. Our figure has been prepared from one of 
these plants which was presented to the Kew collection 
by Messrs. Wallace. There is no difficulty in rearing 
and growing this Primula from seed. Like so many 
other species from China and the Himalaya, P. spicata 
proves strictly biennial, and dies after flowering. Un- 
fortunately at Kew it failed to produce seeds. 

Description. — Herb, monocarpic, up to 6 in. in height. Leaves all radical, 
petioled, oblong- or obovate-elliptic, gradually narrowed at the base into a 
petiole up to 1 in. long, blade f-lf in. long, $-f in. wide, doubly servate-crenate, 
thinly papery, shortly crisped'-pubescent on both surfaces ; midrib somewhat 
prominent beneath, with spreading hairs, lateral nerves about 5 along each 
side, rather raised and forked towards the edge. Flowers shortly spicate, 
spreading or somewhat reflexed, loose, 4-8 together ; peduncle slender, nearly 
6 in. long, whitish-mealy towards the top ; bracts oblong, about j- in. long. 
Calyx wide-campanulate, i in. long, irregularly 5dobed almost to the middle, 
the lobes entire or 2-fid, finely mealy externally. Corolla blue; tube 
cylmdric below, widened upwards, i-i in. long, finely puberulous outside ; 
lnnb | in. across, deeply 5-lobed, lobes 2-lobulate and mucronate. Anthers A 
in, long, inserted at the top of the cylindric portion of the tube. Ovary nearly

The Crassulaceous plant here figured appears to be 
rather rare in collections as well as in nature. It was 
originally collected in woods on the Abkhasia Range in 
the Caucasus, at the base of Mount Hirtscha, by Nord- 
mann some eighty years ago, and Boissier has recorded 
its collection subsequently in the Caucasus by Owerin 
and by Radde. There is in the hei barium at Kew a 
specimen gathered by Nordmann and communicated by 
Ledebour, while there is another obtained in 1893 by 
Alboff, on alpine rocks on Mount Migaria. It is not 
certain how long it has been in cultivation in England 
or by whom it was first introduced ; the material for our 
plate was supplied by Miss Willmott, in whose garden 
at Warley Place it flowered in June, 1916. A graceful 
plant, with opposite decussate, somewhat crenate flattish 
leaves and small yellow flowers borne on branched spikes 
so as to form an open panicle, the species is somewhat 

October-December, 1919. 



remarkable in its natural family and its position is there- 
fore rather open to dispute. When first described by 
Ledebour in 1837 its author placed it in the genus 
Cotyledon, as understood by Linnaeus, and named it 
C. oppositifolia. A few years later Ledebour, however, 
transferred it to the genus Umbilicus, as characterised 
by De Candolle in 1801, though to accommodate this 
Caucasus plant he defined a monotypic section Chios- 
tophyllum. Boissier, in 1872, followed Ledebour's later 
treatment; Bentham and Hooker in 1865, however, 
found it preferable to merge Umbilicus as a whole in the 
genus Cotyledon. This treatment, which is followed here, 
renders it necessary to employ the earlier name, Cotyledon 
oppositifolia, proposed by Ledebour. 

Description.— Herb, perennial, glabrous, prostrate and rooting below, with 
above glabrous erect stems 6-10 in. high. Leaves opposite, decussate, more 
or less fleshy, shortly petioled, elliptic or ovate-elliptic, obtuse, crtnate, 1-lf in.

Euomjiims alatus is found wild over a great area, and 
occurs in Japan. Manchuria, Amurland, North and 
Central China. We have not been able to trace its first 
introduction to this country, but it was cultivated in 
Berlin nearly sixty years ago. According to our 
experience at Kew it does not develop its handsome 
fruits very frequently in our climate, and we are 
indebted to Messrs. Waterer and Crisp of Bagshot for 
the specimens now figured. The species has, however 
long been valued in gardens for its great autumnal 

October-December, 1919. 



beauty, its leaves at that season turning to soft, rich 
shades of red. It may be described as one of the 
best hardy shrubs for autumnal colour, and when, as in 
1917, to this is added the colour effect of its purple and 
scarlet capsules it becomes very attractive indeed. 
From all other cultivated Spindle-trees E. alatus is very 
distinct by reason of the conspicuous corky wings of the 
branches. Prom its nearest ally, E. verrucosus, it is well 
distinguished by this character, also by its shorter cymes 
and more deeply lobed capsules. E. alatus is very 
hardy, even in Central Europe, and likes a position 
exposed to full sunlight It thrives in either a loamy or 
a peaty soil and, failing seeds, can be propagated by 
cuttings. 

Description.— Sh ru b of stiff, open habit, 6-10 ft. high, usually wider than

The genus Thorncroftia, of which the species now 
figured is the only one at present, is a native of the 
Transvaal, where it was collected at Barberton by Mr. 
J. N. Thorncroft, growing among rocks at an elevation 
of 4000 feet, in 1911. When describing the genus Mr; 
N. E. Brown expressed the opinion that T. longiflora in 
general appearance resembles Si/ncolostemon demijlorus, 
Benth., so closely that when not in flower the two might 
possibly be mistaken. When in blossom, however, the 
two are very easily distinguished since in T/iorncroftia 

October-December, 1919. 



the limb of the corolla is 4-lobed whereas in Syncolosiemrm 
the limb is composed of two entire or only slightly 
lobed lips. The 3-partite lower lip of the corolla and 
the deeply 2-fid style separate Thorncroftia from Ort/io- 
sipfion. For the introduction of T. longifiora to European 
collections, horticulture is indebted to the collector in 
whose honour it has been named. From seeds sent by 
him to Mr. R. Irwin Lynch, Curator of the Cambridge 
Botanic Garden, plants were successfully raised and have 
thriven best under the treatment as regards potting, 
soil and watering usual for succulent plants, though 
they succeed satisfactorily in any greenhouse or inter- 
mediate house with good light. Under cultivation 
T. longiflom forms a small shrub of loose habit with 
succulent leaves and is not particularly attractive save 
when in flower, when it is somewhat remarkable for the 
long slender tube of the corolla. For the material for 
our plate we are indebted to Mr. Lynch who supplied 
it from one of the plants which flowered at Cambridge 
in November, 1916. 

Description.— Hero, perennial, densely puberulous throughout. Sterna 
erect, up to 2 ft. high, branched, when young more or less red, ultimately 
rather woody. Leaves short-petioled, elliptic-lanceolate, obtuse, entire or 
obscurely sparingly toothed, cuneately narrowed into the petiole below, rather 
thick, including the petiole J-f m. long, up to \ in. wide, densely beset with

The interesting Orchidaceous genus Sigmatostalix in- 
cludes about a dozen species, the majority of which are 
characteristic of the Andes from Peru northwards to New 
Granada. It is one of the rather numerous small genera 
recognised within the sub-tribe Oncidieae of the tribe 
Vandeae, and is especially distinguished by the ungui- 
cnlate suberect lip, which is usually truncate or sagittate 
at the base, as well as by the elongated column. The 
genus, which now for the first time finds a place in this 
work, extends beyond the Andes, for /■>. costaricensis, the 
species now figured, was discovered in Costa Rica by 
Mr. C. H. Lankester, who sent a living plant to Kew 
which flowered in the collection in October, 1915, and 
remained in bloom for a considerable time ; our drawing 
was made in December of that year. Though the 
interest attaching to thi3 species is mainly botanical, it 
is nevertheless a very graceful little plant, in general 
appearance not unlike a small Oncidium, with the flowers 
borne on an elongated spike. The sepals and petals are

narrow and considerably reflexed, and are pale green 
with a brown central stain ; the sagittately cordate lip is 
deep red-brown with a yellow apex. It thrives satis- 
factorily in a house devoted to species of Oncidium and 
other orchids requiring intermediate conditions.

The striking Rose here figured has been in cultivation 
in the Kew collection as Eosa glutinosa since 1896, in 
which year the plant from which the material for our 
plate has been derived was received from Darmstadt 
under this name. This plant is conspicuous in the 
collection by its dwarf habit and its gooseberry-like fruits 
which ultimately assume an orange-red colour. In Miss 
Wilmott' s magnificent monograph of the genus Rom 
this is figured under the Darmstadt name. It has long 
been suspected, however, that there was some confusion 
and that this is not the original R. glutinosa of Sibthorp 
and Smith. An exhaustive comparison of the material 
preserved at Kew and in the Natural History Museum 
and the examination of the original Sibthorpian type at 
Oxford enabled Mr. Rolfe in 1918 to state definitely that 

Octobbk-Dbcbxbb*i B'19. 



the Darmstadt R. glutinosa is the plant described and 
figured by Kerner in 1870 as R. dalmatica. Kerner's 
plant was collected, probably in 1869, by Mr. F. Maly on 
Mount Bila-Gora, near Cattaro in Southern Dalmatia. 
Living plants were transmitted to Vienna and distributed 
thence, so that it is not impossible that the Kew plant is 
one derived from this source. Borbas has regarded this 
Dalmatian Rose as a variety of R. glutinosa, but has 
recognised the marked difference in the shape of the fruit 
as seen in cultivation. In R. glutinosa proper the fruits 
are globose, not ovoid. In adopting the arrangement 
proposed by Borbas we would point out that the precise 
relationship of the Dalmatian plant to R. glutinosa is not 
yet clear. It certainly belongs to the group of Roses 
from South-eastern Europe and Asia Minor with a close 
affinity to the Rubiginosae or Sweet Briars. To the group 
in question Crepin assigned the name Orientates, and 
treated it as a section which includes R. glutinosa and 
various other forms, some of which are still imperfectly 
known. The dwarf compact habit of R. glutinosa var. 
dalmatica makes it suitable for the Rock Garden or for 
positions where it is not likely to be overgrown by 
shrubs of coarser habit. Its flowers are pleasing and the 
conspicuous covering of glandular hairs makes it interest- 
ing, but its greatest beauty is seen in autumn when its 
bright and bristly fruits are ripe. For so dwarf a rose 
they are noticeably large. The plant must have a sunny 
position and prefers a rather heavy loamy soil.

northern parts of the Arabian Desert within Egyptian 
territory. Its nearest allies in the genus are C. strigosa, 
Russ., figured at t. 5068 of this work, C. fieuteriana, 
Boiss. et Bal., and C. hierosolymitana, Boiss., all oriental 
species, in which the corollas are blue or violet. In 
C. sulphurea the corolla is of an intense yellow colour, a 
character which at once marks it off from the three 
nearly related species mentioned. The plant figured in 
our plate was raised at Kew from seed presented by 
Major P. M. Armitage, Great Budworth, Northwich, who 
had received a supply from Palestine in 1917. The 
plants in cultivation at Kew, though they flowered freely

in October, 1917, did not ripen seed. In 1918 some seed, 
saved from the gift of the previous year, was sown in 
March, and the resulting plants, grown in pans in a frame, 
flowered freely in July. The species unfortunately can- 
not be said to be hardy at Kew, and although it can be 
raised satisfactorily in pots, provided freshly imported 
seeds are available, its liability to attack by slugs makes 
it difficult to preserve in a rock garden or elsewhere out 
of doors.

The South African genus Haworthia, according to the 
recent monograph which we owe to Mr. A. Berger, in- 
cludes some three score species, and it is somewhat 
remarkable that in the case of five-sixths of the species 
enumerated in the ' Flora Capensis ' the precise habitat 
was unknown in 1896. Most of these species were intro- 
duced to cultivation in Europe towards the close of the 
18th and the beginning of the 19th Centuries, during a 
period when the growing of succulent plants was much 
in vogue. Many of these were first described by the 
late Mr. A. H. Ha worth, one of the founders of the Hull 
Botanic Garden, in whose honour Mr. H. A. Duval 
named the genus to which the plant here figured belongs. 
A few of the members of this genus had been described 
by earlier authors as species of Aloe, from which, how- 
ever, Haworthia, as understood by Duval, differs in 
having a perianth with an oblong tube and a bilabiate

limb. The only species of Haworthia recorded from out- 
side South Africa is the Angolan II. angolmsis, Baker, but 
it now appears that this exception is only apparent, for 
H. angolensis has been transferred by Berger to his 
genus Chortolirion as C. angolense. The genus Chortolirion. 
Berger was founded for the reception of those species 
reterred by Baker and Engler to Haworthia which differ 
from the true Haworthias in having their leaves narrow 
and comparatively thin above, but wide and conniving 
™ a bulb-like fashion below. The subject of our plate, 
H. Lhalwim, is a very striking species of columnar habit : 
it bears most resemblance to II. Reinwardtii, Haw , with 
which it agrees in the bronze-purple colour of the leaves 
and in the pearly protuberances on their under and 
outer surface. The material for our figure has been 
derived from a plant raised from a cutting presented 
by Dr. Marloth in 1913. This plant flowered in a 
succulent house at Kew for the first time in 
October, 1916.

The Chinese Gaultheria now figured was originally 
described by Messrs. .Render and Wilson as a variety, 
var. cuneata, of G. pyroloides. The name G. pyroloides 
was originally given in 1864 by Miquel to a Japanese 
plant which he had identified (Ann. Mus. Bot. Lugd.- 
Bat. vol. i. p. 30) with one collected by Sir Joseph 
Hooker in Sikkim in 1849. The name he used was 
attributed by Miquel to Hooker and Thomson. But 
these authors never published such a name, although we 
know that Hooker at one time intended to call the 

Octobek-Dkcesibsr, 1910. 



Sikkim plant " pyrolaefolia," that word being inscribed, 
in his own handwriting, on the original sheet in the 
herbarium at Kew. When drafting the account of the 
Ericaceae for the * Flora of British India' in 1882, 
Mr. C. B. Clarke made use of this indication and 
described the Sikkim Gaultheria as G. pyrolaefolia, Hook, f . 
No reference is made by Clarke to the misreading of 
Hooker's name by Miquel or to its employment by the 
latter to designate a plant from Japan. Nor was there 
any obligation to do so, since a critical examination of 
the available material of both plants proves that the 
Japanese and the Sikkim plants are very distinct species. 
It is found too that the Chinese plant now figured is 
equally distinct from the two with which it has been 
nominally confused. In the Sikkim plant, G. pyrolae- 
folia, Hook. f. ex C. B. Clarke, the leaves are few in 
number and are situated near the end of the twigs, 
rounded-obovate or nearly orbicular ; the anther append- 
ages are shorter than the anther-cells ; the style is much 
shorter than the corolla-tube and the ovary is glabrous. 
In the Japanese plant, G. pyroloides, Hook. f. and Thorns. 
ex Miq., the leaves are numerous, more or less elliptic ; 
the anther-appendages are longer than the anther-cells ; 
the style reaches the top of the corolla ; the ovary and 
fruit are glabrous as in the Sikkim species. Our Chinese 
plant, G. cuneata, Bean, differs from the other two both 
in its narrowly obovate to oblanceolate leaves and in its 
densely hairy ovary and fruit. It is a neat dwarf ever- 
green, perfectly hardy so far as our present experience 
goes. The plant from which our figure was prepared 
was raised at Kew from seed sent "to Kew from the 
Arnold Arboretum in 1909. The seed had been collected 
the previous autumn in Western Szechuan by Mr. E. H. 
Wilson, who states that the plant grows in woodlands, 
nearly always on rocks. It thrives under the same 
conditions as the other Gaultherias, which love a moist 
peaty soil. Propagation is easily assured by its plentiful 
seeds. The Gaultherias are interesting on account of 
their curious fruits. Commonly spoken of as berries, 
and to all appearance such, they are in reality 5-lobed 
capsules almost completely enveloped when ripe by the 
calyx which with age enlarges, becomes fleshy, and is 



often coloured. In G. cuneata, however, it happens to 
be white. 

Description.— Shrub, evergreen, I-I3 ft. high, of close compact habit; 
young shoots very leafy, densely pubescent. Leaves alternate, persistent, 
coriaceous, obovate or narrowly oval, acute, cuneate at the base, shallowly 
crenulate, each tooth tipped with a dark gland ; £-1^ in. long, |-£ in. wide ; 
dark shining green and glabrous above, paler shining green and sparingly 
dotted with glands beneath ; nerves sunk above, prominent beneath ; petiole 
T V in. long. Racemes puberulous, 1-1£ in. long, terminal and axillary; 
pedicels puberulous, furnished with two scarious bractlets. Floivers white, 
cernuous, opening from midsummer onwards. Calyx whitish, 5-lobed, 
the lobes triangular-ovate, A in. long, minutely ciliate. Corolla white, 
urceolate, I in. long, with five very small recurved lobes. Stamens .10, 
enclosed ; filaments puberulous, swollen towards the base ; anthers 2-lobed, 
each lobe terminated by two slender horns ; pollen white. Ovary pentagonous, 
silky-puberulous ; style glabrous, columnar, as long as the corolla. Fruit a 
5-lobed, many-seeded, -pubescent capsule, enclosed except at the top by the 
calyx become white and fleshy, the whole resembling a globose, white berry, 
f in. wide. Seeds minute, shining, brown.
