The fine Paeony here figured is met with fairly generally 
in the Balkan Peninsula from Serbia and Macedonia to 
Roumania, and our illustration has been prepared from 
a plant raised from seed sent to Kew from the Geneva 
Botanic Garden under the name P. romanica. But the 
species also extends beyond the Hellespont ; it has been 

Jan.-Makch, 1918. 



collected on the Keshish Dagh near Broussa, and quite 
recently plants raised from seed secured in the neigh- 
bourhood of Smyrna have been grown in English gardens 
as "Sunbeam." So far, however, from being, as this 
name would suggest, a plant of garden origin recently 
raised, this Paeony is a very distinct and natural species 
with a long and interesting cultural history. It was 
known in the XVI Century to Clusius, who, in an account 
of the vegetation of Pannonia, published in 1583, says 
that it was then grown in the gardens of certain noble 
dames from seeds received from Constantinople. Com- 
paring it with our P. officinalis, Linn., the "Paeony then 
familiar in gardens further west, Clusius pointed out the 
thicker leaves and the richer red, not purple, flowers of 
this Balkan plant which he aptly termed " Paeonia 
byzantina." In 1601 Clusius included the species in his 
renowned Historia and supplied an excellent figure. It 
was still rare in Europe, though we learn from Bessler 
that quite early in the XVII Century it has got as far 
west as the famous garden of the Bishops of Eystedt in 
Bavaria. The elder Bauhin mentioned the plant in his 
Pinax in 1623, but altered its name to " Paeonia 
peregrina flore dilute et sature rubenti." Parkinson in 
his Paradisus in 1629 called it the " red peony of 
Constantinople," and supplied a figure which, though 
clumsy, is unmistakable. It was again mentioned by 
Johnson, who gave a copy of the figure by Clusius in 
the 1636 edition of Gerard's Herbal. This figure 
Morison reproduced in his Historia in 1699. Miller did 
not mention this Paeony until 1759 when, in the seventh 
edition of his Gardeners Dictionary, he included it as 
'* Paeonia peregrina flore sature rubente," and gave the 
Levant as its home. In 1768, in the eighth edition of 
his work, Miller, introducing the Linnean method of 
naming his plants, termed this one P. peregrina, a name 
which still remains valid. But Miller appears to have 
known the plant thus designated by him only from the 
figures given by earlier writers. There is no example of 
the species among his specimens in the Banksian 
herbarium ; the only sheet there on which Miller has 
written the name P. peregrina bears two small specimens, 
both received by him from the Paris garden ; these two 



specimens belong to two distinct species ; neither of the 
two is the "red peony of Constantinople." One, the 
more meagre of the two, appears to be but a form of our 
common garden Paeony with quite glabrous leaves ; the 
other represents a type which occurs in the mountains of 
southern France and corresponds most closely with 
P. monticola, Jordan. Into the pitfall thus prepared the 
first to stumble was the editor of this work, at t. 1050 of 
which Sims in 1807 published as P. peregrina, " upon the 
authority of the Banksian herbarium," not the Byzantine 
plant to which the name belongs, but the plant of 
Provence and Languedoc which Miller had mistaken for 
it. The elder Decandolle followed Sims in the third 
edition of the Flore Francaise in 1815 and maintained 
the same attitude in his Systema in 1818. The error, as 
errors will, has survived in many subsequent publications, 
and although the conception of the species to which the 
name P. peregrina has, since 1807, been misapplied may 
at times have varied, the Balkan plant which Miller so 
designated has always been excluded from it. This is 
doubtless partly due to the fact that, as early as 1818, 
the right of that plant to rank as a species had been 
revindicated by Anderson who, overlooking the confusion 
created in this Magazine, renamed it P. decora ; partly 
to the circumstance that in the same year Decandolle, 
in his Systema, confused the Byzantine plant with 
P. lobata, Desf., a name under which, nowithstanding the 
trouble Decandolle took to rectify his error in the Pro- 
dromus in 1824, our species is still often grown in 
gardens. Handsome as a denizen in a herbaceous border. 
P. peregrina possesses the further recommendation of 
being easily cultivated. It flowers profusely and ripens 
seeds freely.

The genus Pteridophyllum is represented by the solitary 
species here figured, which is a native of the mountains 
of Central Japan and is confined to that area. The 
species was originally discovered by Siebold in the 
province of Sinano. In most botanical treatises the 
genus, which is of much scientific interest, is placed next 
to Hypecoum, itself a connecting link between the 
Papaverme and the Fumarieae. But while this is probably 
the most satisfactory treatment, the affinity between 
Pteridophyllum and Hypecoum is apparently somewhat 
remote. The plant from which our figure has been 
Jak.-Mabch, 1918. 



prepared was purchased for the Kew collection in 1914 
from the Yokohama Nursery Company. The species has 
proved quite hardy at Kew and is perennial. While its 
interest is mainly botanical, for the flowers do not invest 
it with any ornamental or decorative quality, the foliage 
is pleasing and renders it quite worthy of a place in the 
Rock Garden, if only on account of the resemblance, 
which the generic name suggests, that the leaves bear to 
the fronds of a fern. When plants are grown in a frame 
the rosette persists during the winter months, but when 
grown in the open the leaves disappear. Grown out of 
doors the plant prefers shade during the summer months 
and should be given a moist soil. This, it may be noted, 
is the first occasion on which the fruit and the seeds of 
the plant have been described.

A considerable number of terrestrial orchids have long 
been the objects of especial care on the part of certain 
cultivators, both in this country and on the continent of 
Europe, not because they possess striking flowers, but 
because of the attractive character of their foliage. The 
salient common feature of this group of plants, generally 
spoken cf as the "Anoectochilus " group, is the possession 
of a fine and very distinctly marked white or yellow 
reticulation, corresponding with the nerves and Veins, 
upon a deep olive-green ground. Plants belonging to 
this group have always been well represented at Kew, 
where they are grown in the tropical Orchid house, 
lhey occur in nature under peculiar oecological con- 
ditions, and in cultivation they thrive best when grown 
m pans of sphagnum moss under bell-glass covers, each 
plant being set in a small pot containing a mixture of 

•' vk.-AJarch, 1918, 



sphagnum and peat fibre, chopped fine and pressed firmly 
about the roots ; the individual pots are then buried in 
the sphagnum in the pans. The plants are watered 
overhead everyday in the summer and are never allowed 
to approach a condition of dryness in winter. They 
flower only rarely, a fortunate circumstance, since after 
flowering the plant either dies outright or is so much 
weakened that it eventually succumbs. Unless stem 
offsets have been developed, flowering therefore almost 
inevitably results in the loss of the plant, for it is found 
that removal of a flower-spike as soon as it shows itself 
is ineffectual as a means of saving the plant. This habit 
of being practically monocarpic, at all events in culti- 
vation, is unfortunately shared by many terrestrial 
orchids. The genera Lissochilus, Eulophia, Microstylis, 
Satyrium, Disa all contain species which behave in this 
way. Though the plants of this particular group are 
all members of the subtribe Spirantheae, to which the 
genus Anoectochilus belongs, they do not all belong to 
that genus, and until flowers are produced it is sometimes 
impossible to suggest their true natural position. The 
member of the group now figured has exemplified this 
difficulty. This species was originally introduced to 
cultivation by Mr. L. Forget, who had met with it in 
some unspecified locality in the Sunda Archipelgo, while 
collecting on behalf of Messrs. Sander and Sons, St. 
Albans. It was, as usual, tentatively referred in the 
first instance to Anoectochilus, and was described by 
Dr. Kraenzlin in 1895 as A. iSanderianus. A plant flowered 
at St. Albans in 1896, and the flower-spike, sent to Kew 
for examination, made it possible to ascertain that the 
species is really a Macodes. There are other three species 
of the same genus now in cultivation and all three are, 
like M. Sanderiana, natives of Malaya. One of the three 
is the original M. Petola, Lindl., originally placed by 
Blume in Neottia, which is a native of Java ; another is 
M. javanica, Hook, f., figured at t. 7037 of this work, 
which is also a native of that island ; the precise locality 
of the third species, M. Rollissonii, Rolfe, is not known. 
From all three M. Sanderiana is readily distinguished 
because of the much greater width of the brightly 
coloured lines of the venation. It comes even nearer as 



regards its floral structure to M. argyroneura, Rolfe, a 
species not at present to be met with in living collections, 
which Miquel originally referred to Haemaria. In this 
case, however, M. Sanderiana is readily distinguished not 
only by having a coloured venation with wider lines, but 
in having these yellow in place of white. The plant from 
which our figure has been prepared was acquired for Kew 
from Messrs. Sander in -1914. It flowered at Kew in 
September, 1916, and, as is usual, died after flowering.

Indigofera pendula is a charming and graceful shrub 
which * was first collected by the late Abbe Delavay 
in October, 1887, in woods near Lankong in Yunnan. 
In May, 1906, Mr. G. Forrest met with this species again 
on the eastern flank of the Likiang Range, where he 
found it both in open situations amongst scrub and in 
damp shady pine-woods at elevations of 9,000-10,000 
feet. Seeds collected by Mr. Forrest at a later date 
were presented to Kew by Mr. J. C. Williams, Caerhays 

Jan.-Makch. 1918. 



Castle, in 1914, and from these the subject of our 
illustration was raised. The plants grew quickly and 
flowered during August and September, 1916, when our 
figure was prepared. They were cut back to the 
ground-level during the winter of 1916-17, but broke 
freely again from the base, grew during the summer 
to a height of seven feet and flowered freely towards 
autumn. The racemes are pendulous and the largest are 
from 15-18 inches long. Indigofera pendula is most 
nearly allied to I. Faberi, Craib, another Chinese species, 
which has almost ^labrescent young twigs, ovate leaves 
and longer pedicels disposed on shorter racemes. The 
cultivation of /. pendula offers no great difficulty ; the 
plant likes a sunny position and an open well-drained 
soil. Judging from the experience ot the winter of 
1916-17 it is at least as hardy as most of the other 
cultivated Indigoferas, all of which die back to the 
ground-level in winter. Like them it can easily be 
increased by cuttings.

The Agave here figured from material supplied from a 
plant that poled in 1914 in the garden of Lady Hanbury at 
La Mortola, Ventimiglia, Italy, though a species that is 
neither new nor rare, fully deserves a place in this work 
on account of its great economic interest. It is the 
species which supplies from its leaves the fibre known as 
Henequen, a material which rivals in its qualities and 
value, and is perhaps at times confused with the now 
more familiar fibre known as Sisal. The Henequen plant 
is a native of Yucatan in which province of Mexico 
it is also largely cultivated. From thence it has now 
spread to most countries with a tropical or semitropical 
climate, and where it is not grown for the sake of its 
fibre it is used as an effective hedge-plant, or as a 
decorative subject in gardens. It is singular that 
nothing should be known with certainty as to when or 
by whom this species was first introduced to cultivation 
in Europe, and even its introduction as an economic 
species is obscure. It is difficult to believe that this 
species and its rival A. sisalana were unknown to Jacobi, 
yet there is no description by that author which agrees 
entirely with either plant. As regards A. sisalana the 
same is true of Lemaire, and it is only because Professor 
Trelease has been able to associate Lem aire's name 
A.fourcroydes with the species now figured that we believe 
Lemaire to have known the Henequen, for the original 
description of the plant leaves this doubtful. Until 
Trelease thus vindicated the name Lemaire had pro- 
posed, the nomenclature of the Henequen was somewhat 
confused ; other authors, unwilling to establish a new 
species, have endeavoured to associate the Henequen with 
A, rigida, Mill., A. elongata, Jacobi, A. mndelahrum, Todaro, 
and yet other species from which it differs very markedly. 
A, foureroydes belongs to the subgenus Euagave, and 
within this its affinities are with the Sisalanae group of 
the Rigiclae, among which it is characterised by its 
narrow leaves and non-decurrent end-spine. Reproduc- 
tion is singularly well provided for in this species. The 



rosette throws out suckers ; the panicle gives rise to great 
numbers of viviparous bulbils, and at the same time 
ripens capsules which contain an abundance of seeds. 

Description. — Shrub, developing a stem 3-4 ft. high and 10 in. thick, 
emitting suckers at the base. Leaves numerous in a terminal rosette, rigidly 
erecto-patent, 4£ ft. long, oblanoeolate-ensiforiu, 4 in. or more wide above the 
middle, gradually narrowed towards the base, apex rather shortly acuminate, 
not very fleshy, glaucous and somewhat pruinose, smooth, convex on 
the upper surface near the base, then flat and channelled with upcurved 
margins, underneath convex and almost keeled ; margins armed from the base 
to about 2-3 in. below the end-spine, basal prickles very small, often confluent, 
the others about 1-1 | in. apart, blackish, with a broad horny base and a fine 
short point, 1-2 lin. long, the lower recurved, the others upcurved (sometimes 
the point twice bent), the margin between almost straight ; end-spine stout, 
conic, 1} in. long, a little recurved, not decurrent, round, grooved below the 
middle, blackish-brown. Inflorescence about 18-21 ft. high, straight or slightly 
curved at the top ; scape stout, green, with numerous adpressed triangular 
acute empty bracts ; panicle oblong-pyramidal, rather loose, with about 15-20 
branches, which are patent, tripartite at the top, with numerous flowers in 
dense clusters ; pedicels very short ; bracts minute, deltoid, soon withering. 
Flowers 2^-3 in. long. Perianth tube about | in. long, 6-furrowed, broadly 
obconic-campanulate ; segments about as long as or a little longer than the 
tube, linear, obtuse, j'ello wish -green, soon withering. Filaments inserted in 
the middle of the tube, 2-2| in. long ; anthers 1 in. long, yellow. Ovary 
cylindric-clavate, somewhat triangular, green, pruinose, constricted at the 
top, If in. long; style 3 in. long; stigma clavate. Capsule oblong-clavate, 
obtusely triangular, 3-furrowed, with stipitate base and beaked apex, over 
2 in. long. Seeds almost semiorbicular, 4.J-5 lin. long, black. Bulbils very 
numerous.

The dwarf Rhododendron here figured is a native of 
Yunnan, where it was discovered in June, 1910, by 
Mr. G. Forrest, as a prostrate shrub 2-4 inches high, 
trailing over rocks and on moist peaty soil almost at 
the limit of vegetation, on the eastern flank of the 
Likiang Range at elevations of 15,000-16,000 feet. 

Jan.-March, 1918. 



Seeds sent by Mr. Forrest to Mr. J. C. Williams, 
Caerhays Castle, were sown there in 1910, and the 
material for our figure has been provided by a plant 
presented to Kew by Mr. Williams which flowered in 
April, 1917. This species, which has been named 
Jt. prostratum at Edinburgh by Mr. W. W. Smith, comes 
near to B. nivale, Hook, f., from Sikkim, with which it 
agrees in habit, but from which it differs in having larger 
ciliate leaves and densely villous flower-stalks. There is 
no doubt that R. prostratum is one of the most distinct 
and beautiful of the dwarf species now in cultivation. 
It has shown itself perfectly hardy in this country so far 
as winter cold is concerned, but whether its flowers will 
escape the later frosts remains to be seen. The month 
of April, 1917, being very inclement, the Kew plant was 
taken into a cool greenhouse as soon as the flower-buds 
began to open, in order to preserve the blossoms from 
injury by the frost and snow then prevailing. 

Description.— Shrublet, 2-4 in. high ; twigs numerous, prostrate, the older 
ones brown or grey, the younger pale green, beset with rather dense weak white 
hairs; new shoots f-1 in. long, laxly leafy like the shoots of the previous

The genus Echeveria was proposed by Deeandolle in 
1828 for those species from America which earlier 
authors had referred to Cotyledon, originally founded by 
Linnaeus on African and Mediterranean plants. The 
new genus differed from Cotyledon mainly in having the 
petals connate only at the base and the stamens shorter 
than the petals. In 1865 Bentham and Hooker declined 
to accept these differential characters as adequate. In 
their view the only character by which Echeveria could 
be distinguished from Cotyledon is to be found in the 
pentagonal corolla. But floristic convenience at times 
finds monographic canons unduly severe, and its dictates 
have induced Dr. Rose to reconsider the verdict of the 
Genera Plantarum. In 1903 this careful student reverted 
to the view of Deeandolle, and two years later definitely 

Jais-.-March, 1918. 



resuscitated Echeveria, which as defined by him, includes 
some sixty species, mostly Mexican, though some occur 
in Central America, a few in South America, and one is 
met with in Texas. It has to be noted, however, that 
while he accepts the view of Decandolle in preference 
to that of Bentham and Hooker, the character on which 
Dr. Rose lays greatest stress is that pointed out in the 
Genera Plantarum ; Edieveria, Rose, as contrasted with 
Echeveria, DC., must consequently be held to include 
several South African plants with a pentagonal corolla. 
This suggests consequences which need not be discussed 
in connection with E. setosa. the species now figured, 
which has, so far, only received a name in the genus 
Echeveria. This plant, readily distinguished from all its 
congeners by its setose leaves, was discovered in 1907 by 
Dr. C. A. Purpus on the Cerro de la Yerba, near San Luis 
Tultitlanapa, Puebla, South Mexico. Plants were pre- 
sented to Kew in 1910 by Dr. Britton, New York Botanic 
Garden, and m 1912 another was acquired from Messrs. 
Haage and Schmidt, Erfurt. From the latter, which 
flowered in 1914, our figure has been prepared; two 
smaller leaves have been added to the plate from a 
plant presented by Dr. Britton. In England E. setosa 
can only be grown under greenhouse conditions. It 
flowers regularly and produces offsets freely.

The plant figured here under the name of Petunia 
integrifolia (though much better known as P. violacea) 

Jan.-March, 1918. 



first appeared in our gardens in 1831, having been raised 
from seeds sent to the Glasgow Botanic Garden by John 
(by some writers erroneously called James) Tweedie, who 
was at that time residing in Buenos Aires. The genus, 
now comprising twenty-nine species, was established in 
1803 by Jussieu who, at the same date, described two 
species, P. parviflora and P. nyctaginifiora. There was an 
interval of nearly thirty years before the third species, 
the subject of this note, was discovered. P. nyctaginiflbra, 
which appears to hive been in cultivation in the Jardin 
des Plantes, Paris, in 1820, was figured at t. 2552 of this 
Magazine in 1825, yet it seems to have been so far over- 
looked when Sir William Hooker described Tweedie' s 
new introduction six years later that the latter was not 
recognised as belonging to the same genus, and was 
published at t. 3113 as Salpiglossis integrifolia, the figure 
then given being scarcely a faithful representation of the 
species. The plant immediately became a favourite. 
Pretty and graceful as it was in itself its possibilities as a 
subject for crossing with P. nyctaginifiora were quickly 
realised. Florists took it up with remarkable success ; 
artists repeatedly made drawings of it, and often poor 
ones, and botanists repeatedly described it, giving it at 
least nine names under five different genera. A hybrid 
was first obtained in 1834 by a nurseryman named 
Atkins of Northampton, and this was figured and 
described in Sweet's Brit. Fl. Gard. ser. 2, vol. hi. t. 268 
as Nierembergia Atkinsiana. Many forms of the hybrid 
soon appeared in gardens, and three were figured at 
t. 3556 of the Botanical Magazine. Details as to the 
evolution and history of the Petunia have been given by 
L. H. Bailey (Survival of the Unlike, p. 465), Le Texnier 
(Rev. Hort. 1908, p. 377) and Lotsy (Archives Neerlan- 
daises, ser. 3 B, vol. ii. p. 221). The true P. integrifolia 
disappeared from cultivation, though plants passing 
under the name of P. violacea were still met with in 
collections. The P. violacea which has been cultivated 
in the Chelsea Physic Garden for many years— it was 
found there when Mr. Hales became Curator in 1899— is 
quite distinct from the true plant. It has an erect habit 
of growth, rather like that of P. nyctaginifiora, and bright 
rose-coloured flowers with a whitish throat and a paliid 



exterior ; the eorolla-tube is rather longer than that of 
P. integrifolia, and is funnel-shaped rather than ventricose. 
It agrees with the description of P. violacea var. " Gloire 
de Segrez " in Vilmorin-Andrieux, Les Fleurs de Pleine 
Terre, ed. 3, p. 848, which was raised from a garden 
Petunia known as "Marquis de la Ferte." It is said to 
reproduce itself exactly by seed, and is believed to be 
the same as P. violacea oculata, Hort., and P. " Countess 
of Ellesmere." In 1911 an effort was made by Kew to 
secure the re-introduction of the true P. integrifolia from 
South America, and a request for seeds was sent to 
Sir Reginald Tower, His Majesty's Minister at Buenos 
Aires, who had on many previous occasions given 
invaluable help to the establishment. The trouble he gave 
himself in consequence of this request seemed endless, 
and amongst others whom he interested in the search for 
the plant should especially be mentioned Mr. Carlos 
Thays, at that time Director-General of Public Parks, 
Buenos Aires, and Mr. C. E. R. Rowland, Vice-Consul at 
Monte Video, since 1916 Vice-Consul in Mexico, where, 
we deeply regret to hear, he died in 1917. Mr. Rowland 
was at last successful in obtaining seeds of both P. integri- 
folia and P. nyctaginiflora from a virgin district on the 
banks of one of the small tributaries of the River Plate 
in Uruguay, and these reached Kew in September, 
1916. A plant of P. integrifolia raised from these seeds 
flowered in June, 1917, and provided the material for our 
figure. The species is now known from the Southern 
states of Brazil, from Paraguay, Uruguay and the 
Argentine Republic. It appears to vary considerably, 
and there js reason to believe from specimens in the 
Kew Herbarium that there are natural hybrids between 
it and P. ngctaginijlora. Dr. Fries has described as a 
subspecies, named depauperata, a form with smaller 
leaves, shorter peduncles and smaller flowers. His 
P. infiata must be very clcsely allied to P. integrifolia, 
and judging from the specimens at Kew, which, it should 
be stated, form but a small part of the material cited by 
Dr. Fries, it cannot be satisfactorily distinguished. It is 
characterised mainly by the peduncles remaining erect 
after flowering, while in P. integrifolia they are more or 
less deflexed. The cultivation of P. integrifolia presents 



no difficulty other than those experienced in connection 
with the very varied garden Petunias which are now 
generally raised from seed. As long ago as 1866 
Mr. Naudin pointed out that neither P. integrifolia nor 
P. nyctaginifiora vary when raised from their own seed, 
but that when intercrossed they yield hybrids as fertile 
as themselves ; these hybrids being all alike in the first 
generation, but in the second varying in the most 
remarkable degree. Modern Petunias owe more to the 
skill and attention of Mr. E. Benary of Erfurt than to 
any other cultivator. Mr. Benary separates his forms 
into several groups and claims that some thirty per cent, 
of his forms come true from seed. The plants are treated 
as tender annuals and are largely grown for summer 
bedding ; the seeds are germinated in spring in heat and 
the seedlings planted out of doors in May. The plants 
may also be grown in pots for conservatory decoration. 
A light soil and abundance of summer heat and direct 
sunshine are essential to their freedom of growth and 
flower. In Mr. Benary's experience the best Petunias are 
not those that show most vigour in the seedling stage. For 
this reason he has always made it his practice to discard 
the strongest seedlings when pricking them out from the 
seed pan.

The neat Rhododendron here figured is a native of 
Yunnan, where it was discovered by Mr. G, For; est in 
open rocky situations in dry pine forests on the eastern 
flank of the Tali Range, at 11,000 feet, and on the 
Mekong-Salwin Divide to the north-west of Tse-kou at 
13,000 feet. In the latter locality it has also been 
collected by the Rev. Pere Monbeig, while in the former 
it was obtained on Tsang-chau by the Abbe Delavay, 
whose specimens, which match exactly that now figured, 
were made the basis of R. brachyanthum, Franch. Our 
plant, it may be mentioned, is by some authorities 
regarded as a form of the plant subsequently described 

Jan.-March, 1918. 



by Franchet as R. sulpltureum. Should this prove to be 
the case the latter name must disappear from our lists. 
The material for our plate has been derived from a plant 
raised from seed supplied by Mr. Forrest to Mr. J. C. 
Williams, Caerhays, who informs us that in spite of the 
affection of the plant for open situations in its native 
home, and though it is not a shade-loving species, it does 
not survive in this country if given a hot place in the 
sun. With partial shade it proves quite hardy. When 
in fruit, as Mr. Williams points out, it is exceedingly like 
II. glaucam, Hook, f., a native of Sikkim with rose-lilac 
flowers and acute calyx-lobes. It is also very nearly 
allied to R. campylogynum, Franch., a Yunnan species 
with pale rose-purple flowers. 

Description.— Shrub, sparingly branched ; branches stout, strict, stiff ; twigs 
of the previous season laxly leafy upwards, finely lepidote, clothed with brown 
polished bark ; young twigs densely covered with yellow scales. Leaves 
elliptic or oblong-elliptic, obtuse and distinctly mucronate, base obtuse, J-1J 
in. long, f-| in. wide, firmly coriaceous, green and sparsely lepidote above, very 
glaucous and sparingly glandular-lepidote beneath ; midrib faintly sunk above, 
distinctly raised beneath and there glandular but not glaucous ; lateral nerves 
rather inconspicuous, sunk above ; petiole £— J in. long, stout, glandular. 
Flowers umbellate, terminal, 3-4 together; scales caducous, coriaceous, 
densely ciliate, glandular on the back, the outermost leafy and glaucous below ; 
pedicels erect or slightly drooping, about | in. long, glandular-lepidote. Calyx 
large, rather leafy, deeply 5-lobed, lepidote towards the base outside, about 
} in. long, i in. wide, margins undulate, glabrous. Corolla pale yellow ; tube 
wide campanulate, § in. long, glabrous ; lobes 5, very wide ovate, auriculate at

The Asparagus here figured is an old garden plant 
which has long been in cultivation as a greenhouse 
climber. It is a native of Ceylon, where it is known as 
the Hatawariya. This, however, is an outlying locality 
for the species, though it happened to be the region from 
which the species was originally known, for it occurs also in 
Tropical Africa and in the Eastern region of South Africa 
outside the Tropics. As its nearest ally, A. Sprengeri, 
Hegel, is a native of the last mentioned region the 
possibility of our plant being an early introduction to 
Ceylon should not be overlooked. There is a fine 
example of A. falcatus in the Temperate House at Kew 
which forms a screen thirty feet high, clothing a staircase 
at the northern end of the building. In those seasons in 

Jan-.-Mauch, 1918 



which this plant flowers freely, which it usually does in 
June when it blossoms at all, the whole building becomes 
pervaded by its honey-like odour. Another example, 
from which the material for our figure has been derived, 
forms a striking mass which drapes one of the pillars in 
the Succulent House. Like the companion plant this 
only flowers freely in certain seasons ; it did so profusely 
in June, 1913. The species thrives best if planted in 
poor gravelly soil ; it may be propagated either from 
seeds when these are produced, or by means of cuttings 
taken from the smaller branches. The figure supplied by 
Burmann, which Linnaeus has cited, appears to be a bad 
drawing ; it shows the flowers as fascicled, which is not 
the case with our species. There has been some confusion 
between A. falcatus now figured and its Natal ally, 
A. Sprengeri, the fruit of which has been figured at 
t. 8052 of this work, while its flowers have been figured, 
under the name A. ternifolim, Hook, f., at t. 7728; 
A. Sprengeri has also been figured in Saunders' "Re- 
fugium " as A, aethiopicus, var. ternif alius. Both plants 
belong to a group of species in the genus Asparagus 
characterised by having flattened cladodia and race- 
mose inflorescences. But they are readily distinguished 
because in A. Sprengeri the cladodia are straight 
instead of falcate and are but half as broad as those of 
A, falcatus, while the prickles on the main-stem of 
A. Sprengeri are smaller than those of A. falcatus and are 
hooked. The two species agree in having terete 
branchlets, and in this character both differ from 
A. aethiopicus, Linn., with which they have been confused, 
but which has the branchlets strongly angled. 

Description. — Shrub, widely scandent. Stems stout, terete, woody; 
branchlets slender, flexuous, terete, woody, straw-coloured. Leaves of the 
stem reduced to rigid, sharp, spreading spines. Cladodes along the stem 
i, o -i at the ends of the twi S s in clusters of 6-8, lanceolate, falcate, 

l 4 -2 in. long, I-} in. wide, bright green, firm. Bacemes axillary, 1-3 together, 
2 to. long; pedicels 1-3 together, jointed near the middle, JUi in. long; 
bracteoles ovate, half the length of the pedicels. Flowers white, sweet scented. 
terxanth campanulate ; lobes spreading, oblong, obtuse, entire, r \ in. long. 
btamens rather shorter than the perianth-lobes ; anthers minute. Ovary ovoid, 
narrowed at the base; style short, roundly 3-lobed. Berry globose. \ in. 
across, usually 1-seeded.

This striking Primula was discovered by Mr. G. Forrest 
in open moist pastures on the mountains of the Chungtien 
Plateau in Yunnan, at an altitude of about 11,000 feet 
above the sea, in July, 1913. He met with the species 
again in the same general locality in July, 1914. The 
flowers are of a deep purple, almost black colour, and all 
parts of the plant when fresh are strongly aromatic, the 
odour resembling that of aniseed. Owing to this circum- 
stance Professor Bayley Balfour and Mr. Forrest in 
describing the species have given it the name P. amso' 
dora. Seeds of the 1913 introduction, presented by 
Mr. J. C. Williams of Caerhays Castle, Cornwall, in 1915, 
yielded plants which flowered in the Rock Garden at 
Kew at the end of June, 1916. It has proved quite 

April-June, 1918. 



hardy in a sheltered nook, surviving the winter and 
flowering again in the summer of 1917. The material 
for our figure has been derived from a plant raised by 
Mr. Williams from seeds of the second collection by 
Mr. Forrest made in 1914. This plant flowered in the 
garden of Mr. Williams in June, 1917. P. anisodora is a 
member of the section Candelabra, and it has, according 
to its authors, a very near ally in P. glycoxma, Petitm., 
also a Yunnan species. The dark flowers, perhaps the 
darkest in any Primula, with their yellow " eye," recall 
those of the Auricula, once so familiar a feature of 
English gardens in spring. Like many other species of 
Primula, P. anisodora dies after flowering freely, but 
produces an abundant supply of good seeds. 

Description. — Herb, producing a scape up to 3 ft. in height, all parts devoid 
of mealiness. Leaves oblong-oblanceolate, rounded and apiculate at the tip, 
gradually narrowed below into a broadly winged petiole, 6-8 in. long, 2-3 in. 
wide, chartaceous, the margin closely and sharply repand-denticulate, bright 
green and glabrous above, beneath more or less gland-dotted ; lateral nerves 
about 10 along each side, diverging from the midrib at an angle of 45°, visible 
on both surfaces ; midrib rather pale in colour, within the petiole flattened and 
streaked with red. Flowers forming a terminal, interrupted umbel ; peduncle 
stout ; bracts linear, acute, glabrous, up to { in. long ; pedicels about \ in. long, 
nodding. Calyx campanulate ; tube \ in. long, red and green ; lobes wide- 
ovate, apiculate, ■$+ in. long, T 'g in. wide. Corolla dark plum-purple outside, 
lobes red-purple within, with a yellow eye ; tube cylindric below, widened and 
slightly campanulate upwards, about f in. long ; lobes usually 5, somewhat 
quadrangular. Anthers oblong, adnate to the middle of the tube. Style as 
long as the ovary, tipped by the globose stigma. Capsule almost globose, 
slightly exceeding the hardly altered calyx, opening by means of 5 valves and 
crowned by the dark-red crenulate style -base.

The interesting terrestrial Orchid here figured is a 
native of the Eastern Himalaya and the Khasia Hills, 
where it is met with in forest at elevations of 5,000 to 
7,000 feet above sea-level. It was originally described 
by Lindley, eighty years ago, from herbarium material, 
as Anoectochilus lanceolatus, but having been found by 
Mr. Bentham to belong rather to Blume's allied genus 
Odontochilus, which differs from Anoectochilus in having a 
bilobed globose sac in place of an oblong spur, in the 
details of the column and in having leaves that are not 
reticulately veined, it was transferred to Odontochilus by 

Apkil-June, 1918. 



Sir Joseph Hooker. In their account of the Orchids of 
the Sikkim Himalaya, Sir George King and Mr. Pantling 
have advanced reasons of some weight in favour of the 
reunion of these two genera and the inclusion with them 
of Lindley's genus Haemaria, but this course, if adopted, 
involves so much rearrangement that it appears prefer- 
able in this work to follow the generic limitation 
accepted by Bentham in the " Genera Plantarum." 
Though so long known from dried specimens, this species 
is of very recent introduction to European horticulture. 
It flowered in September, 1915, among the terrestrial 
orchids in the collection of Mr. H. J. Elwes, at Coles- 
borne, Cheltenham, and our figure has been prepared 
trom a plant in flower sent by him to Kew for identi- 
fication and for inclusion in the orchid collection at Kew. 
It flowered, Mr. Elwes informs us, in a damp and shady 
intermediate house in which it had thriven well. The 
flowers are light green with a brown patch at the tip of 
the dorsal sepal ; the lip, however, is bright yellow and 
the anther is pink. The leaves are green with three 
bright stripes. The plant figured was received from 
bikkim where it had been collected by Mr. G. H. Cave, 
Lloyd Botanic Garden, Darjeeling.

The Zanthoxylum here figured is a native of Japan, 
which is known in collections of hardy shrubs as 
Z. planispinum. It is, however, doubtful how far it is 
entitled to rank as a species apart. It is one of the series 
of forms to be met with in Japan and Corea which 
extend thence throughout China to Northern India, and 
which are so intimately related that some authors regard 
them as belonging to the Indian Z. alatum, Roxb. But 
while from the botanical standpoint it may be possible 
or even necessary to adopt this view, it is one that from 
the cultural point of view is distinctly inconvenient. 
In the Japanese form shown in our plate there never 

April-June, 1918. 



are more than five leaflets to a leaf ; in the true 
Z. alatum from India there are frequently thirteen 
leaflets. In our Japanese plant the spines are restricted 
to the nodes ; in the North Indian type the spines 
often are internodal. The Japanese Z. planispinum is a 
fairly hardy garden shrub ; at Kew it is impossible to 
keep Z. alatum alive out of doors for any length of 
time. The material for our figure came from the garden 
of Bitton Vicarage, and a melancholy interest attaches to 
our subject in its being the last contribution to the 
Botanical Magazine by one who was for many years its 
unfailing and enthusiastic supporter. Canon Ellacombe 
sent the fruits in December, 1914, and the flowers in 
June, 1915, only a few months before his death. At 
Bitton Z. planispinum forms a bush six feet high and 
rather more through. It succeeds there very well in the 
good loamy soil, and its fine crop of red fruits make a 
very ornamental object in the winter season. Canon 
Ellacombe was always greatly interested in the way its 
leaves roll their margins under during the winter, as is 
also the habit of some Himalayan Rhododendrons at the 
same season. This, by minimising the leaf surface 
exposed to radiation, may be a protection against great 
cold. 

Description.- Shrub of bushy, spreading habit, 6-12 ft. high; branchlets 
purplish-brown, glabrous or nearly so, armed with a pair of spines at each node ; 
spines thin, flat, triangular, |-f in. long by i-4 in. wide at the base, ending in 
a hard slender point; lenticels small, whitish. Leaves semi-persistent or 
deciduous, alternate, aromatic when crushed, 3-10 in. long, unifoliolate, tri- 
foliolate, or pinnate with five leaflets ; rachis winged, i-f in. wide, often armed 
with one or more slender spines; leaflets subsessile, narrowly elliptic to 
lanceolate, 1-5 m. long, J-lj in. wide, the apex acuminate, the base cuneate, 
the margins shallowly crenate with a circular gland on each tooth ; dark green 
and glabrous above, pale beneath, with a tuft of brown pubescence on the 
midrib near the base. Panicles axillary, 4-1 in. long, minutely pubescent. 
flowers polygamous, greenish, very small and inconspicuous. Sepals and 
petals subulate. Ovary glabrous, flask-shaped, oblique; style decurved ; 
carpels usually two. Fruit 2-valved, globose, verrucose, * in. wide, red, 
containing one shining black seed.

The genus Erlangea is closely allied to the important 
Composite genus Vernonia, Schreb., from which, how- 
ever, it is readily distinguished by its reduced achenes 
crowned with a pappus composed of very short and 
caducous setae, incapable of playing any part in the 
distribution of the ripe fruit, the genus, as circum- 
scribed in accordance with this striking feature, includes 
some four and thirty species, all but one of which are 
natives of Tropical Africa. The remaining species is a 
native of New Guinea, a circumstance which must, never- 
theless, be regarded as of no significance from the phyto- 
geographical standpoint, since the feature that admits 
the Eastern plant in question within this characteristic- 
ally African genus is, in spite of its practical utility, a 
somewhat artificial one. From the systematic stand- 
point the existence of this New Guinea plant is, however, 

April-June, 1918. 



of importance, as indicating the danger that may attend 
reliance upon characters related with function in the 
discrimination of forms or groups of plants. The species 
now described, E. aggregata, is a native of Angola, where 
it was discovered by Mr. J. Gossweiler, by whom seeds of 
the plant were presented to Kew in 1915. It shares 
with E. spissa, S. Moore, a species from British East 
Africa, the character of densely aggregated flower-heads, 
which separates the two from all the other known 
members of the genus. The West African plant is 
readily distinguished from the East African one by the 
characters pointed out by Mr. Hutchinson. The 
material for our plate has been derived from one of the 
plants raised from Mr. Gossweiler's seed. The species in 
cultivation reaches a height of from five to six feet, 
branches freely and forms a striking object when 
furnished with its numerous terminal showy flower- 
heads. As it blossoms in this country in midwinter, 
and is a perennial, it is likely to become a popular green- 
house plant. Cuttings are readily struck, and from these 
full-sized plants may be grown in a single season.

The genus Monadenium was established by Pax in 1914 
on a species from East Africa with the floral structure 
characteristic of the genus Euphorbia, Linn., but easily 
distinguished from Euphorbia owing to the great develop- 
ment of the glandular apparatus of the cyathium. In 
this respect Monadenium, Pax, agrees with Synadenwm, 
established by Boissier in 1862 on a Natal species, though 
in that genus the glandular ring is closed and not open

on one side as in Monadenium. Two more species were 
added to Monadenium by Dr. Stapf in 1900, and since 
then the number of known Monadenia has increased to 
a score. Most of them appear to be extremely local ; 
the area occupied by the genus extends from Abyssinia 
and Somaliland to Nyasaiand, Ngamiland and Angola. 
Within the genus Monadenium, however, the species 
arrange themselves in two natural groups. In the first 
group, to which the original M. coccineum, Pax, belongs, 
the bract-involucres are distinctly dorsi-ventral, the two 
bracts being asymmetric, and so joined on one side as 
to form a single 2-keeled and usually 2-dentate or 
2-cuspidate involucre. In the second group, to which 
the subject of our figure belongs, the bract-involucres are 
fairly regularly cupular or bell-shaped, the two bracts 
being nearly symmetric and usually equally united at 
the base or up to the middle. With these characters are 
associated in our plant that of having simple axillary 
inflorescences in place of branched inflorescences as in 
M. coccineum, and that of the presence of a perianth in 
the female flower whereas in M. coccineum no perianth 
was noticed by Pax. On this account the plant now 
described was made the basis of a distinct genus 
Lortia by Rendle in 1898, and the validity of this 
genus has since been accepted by Pax. An examination 
of the original type of Monadenium shows, however, 
that there the female flower has a perianth very 
like that of Lortia, and since the degree of branching 
in the types of the two genera merely represents 
extreme manifestations in opposite directions of one 
character, it has been found by Brown to be desirable to 
include Lortia in the older "genus Monadenium. The 
difference in the involucre of the two types is, however, 
so marked that it is at least necessary to recognise in 
Lortia a distinct section, and it may with fuller knowledge 
be advisable to restore it to the rank of a genus. The 
type of this section, M. (Lortia) erubescent, was discovered 
by Mrs. Lort Phillips on the Wagga Mountains in 
Somaliland in 1897, and was met with again on the 
Colis Range in Somaliland, at nearly 6,000 feet elevation, 
by Dr. Drake-Brockman in 1914. Other specimens 
obtained by the same collector from the Arussi and 



Boran countries in Abyssinia, attributed by Brown to 
M. erubescens, we believe to represent a distinct species. 
The material for our illustration has been provided from 
a living plant from Somaliland, presented to Kew by 
Dr. Drake-Brockman which has grown well and proved 
quite healthy in a warm succulent house under the 
treatment suitable for species of Stapelia, During the 
first two winters the stems formed in the preceding 
summers died down. It flowered in July, 1916, when the 
drawing was made, but has not done so again, though 
since then the stems formed have persisted, and the plant 
now possesses several of these, the longest of which is 
three feet long with a few leaves near the top. Young 
plants have been raised from cuttings, which root readily 
in spring. 

Description. — Herb, with a perennial globose tuber 8-14 in. in diameter.

Malus Sargentii was discovered by Prof. C. S. Sargent 
in Japan in 1892 near a brackish marsh at Mororan, 
Hokkaido. It is a close ally of M. Toringo, Sieb., 
differing from that species in its larger flowers, over- 
lapping petals, and larger fruit; from another related 
species, M. Zumi, Eehd., it is distinguished by its glabrous 
calyx-tube, orbicular petals and often lobed leaves. The 
material for figuring was gathered from a plant purchased 
from Messrs. Veitch in 1909, but a plant had previously 
been presented to Kew from the Arnold Arboretum in 
1904. As a garden shrub, or perhaps a small tree, 
M. Sargentii is very attractive both in flower and when

it more ornamental than M. Toringo, and it is as hardy 
as any of its allies.

The Madagascar Angraecum now described was intro- 
duced from that island some years ago by Messrs. 
Charlesworth and Company, Hayward's Heath. The 
individual flowers in this species bear so close a resem- 
blance to those of A. recurvum, Thouars, also a native of 
Madagascar, that when in November, 1913, an example 
flowered in the establishment of Messrs. Charlesworth, 
it was exhibited in public and was accorded an award 
of merit under the name A. recurvum, which was 
also employed in connection with figures of the plant, 
reproduced from a photograph, published in the same 
year. An example purchased from Messrs. Charlesworth 
for the Kew collection of orchids flowered there in 
November, 1916, and enabled the figure here given to 
be prepared. The study of this plant has made it clear 
that it belongs to a species, which may be termed 
A. gracilipes, very distinct from the true A. recurvum in 
its greatly elongated pedicels and its much larger leaves. 

April-June, 1918. 



It is a member of a distinct group of species, one of 
which is A. fragrans, Thouars, figured at t. 7161 of this 
work, whose sweet-scented leaves, known as " Fahame," 
have been used after the manner of tea leaves in Bourbon 
and Mauritius. A. gracilipes thrives well in the same 
house and with the same treatment as that required for 
the well-known A. eburneum, Bory, figured at t. 4761 
and A. sesquipedale, Thouars, figured at t. 5113 of this 
work. It is remarkable in the genus for the unusual 
length of its pedicels which appear in the lower leaf-axils 
of a short stout stem, and when, as sometimes happens, 
over a dozen flowers are simultaneously produced, the 
plant forms a very graceful object. 

Description -Herb, epiphytic; stems short. Leaves distichous, nearly 
erect or slightly recurved, lorate, shortly 2-lobed, 3^-74 in. long, f-2 in. wide, 
coriaceous, conduplicate at the base. Pedicels axillary, slender, suberect or 
slightly recurved, 6-7^ in. long, 1 -flowered, bearing a few spathaceous sheathing 
bracts. Mowers showy, white. Sepals and petals spreading, lanceolate, 
obtuse, 1-J ¥ m. long. Lip subpandurate -ovate, obtuse, 1-11 in. long, some- 
what conduphcate at the base; spur slender, 2i-2f in. long, curved and 
thickened at the base. Column wide, \ in. long, widely auricled on each side, 
the auricles truncate and entire. Pollinia 2, orbicular and slightly compressed ; 
stalks very short ; gland oblong.

The Rhododendron here figured is a native of Yunnan, 
where it was originally met with by the Abbe Delavay 
and where it has since been collected by Messrs. Ducloux, 
Soulie, Wilson and Forrest. The last mentioned traveller 
records it as occurring on dry wooded hills to the north 
of the Tsu-hsiong-fu valley at elevations of from 6,000- 
7,000 feet. It was first described by the late Mr. 
Franchet as R, siderophyllum. Its nearest ally in the 
genus is R. Davidsomanum, Rehd. & Wils., figured at 
t. 8605 of this work, and it shares with that species and 
a few others belonging to the group with glandular 
leaves the peculiarity of producing its flowers from 
several axillary buds, instead, as is more usual, of doing so 
only from a terminal one. From R. Davidsomanum our 

April-June. 1918. 



plant differs in its much more densely glandular leaves, the 
under surface of which has in consequence a decidedly 
rusty and rather dirty look, while the upper surface is 
usually conspicuously marked with black glands of con- 
siderable size. In cultivation at Kew R. siderophyllum 
grows very well, and although rather thinly furnished 
with leaves, it flowers very freely and is quite hardy. 
The plant from which the material for our illustration 
has been derived was raised from seeds collected by 
Mr. E. H. Wilson and received at Kew in the spring of 
1909. Certain plants grown by Messrs. Veitch in their 
Coombe Wood nursery under the name R. siderophyllum, 
belonged, so Messrs. Render and Wilson now find, to the 
species they have named R. Davidsonianum. There is, 
consequently, some confusion in gardens between these 
two species which it is hoped that a study of the present 
plate and of the plate referred to above may help to 
clear away.

This is one of two closely allied species which have 
been separated from the genus Kentia, Bl., on account of 

April-June, 1918. 



having numerous stamens (Ken fin having only 6), and 
because of the absence of staminodes from the female 
flowers. 11. Belmoreana, like its ally, 11. Forsteriana, is 
confined to Lord Howe Island, where it was reported by 
Messrs. C. Moore and Carron, its discoverers, as common 
at altitudes below 1,000 feet. Its specific name is in 
honour of the Right Hon. the Earl of Belmore, who was 
Governor of New South Wales in 1868. The flowers of 
H. Belmoreana, as stated by F. Mueller (Fragm. viii. 234), 
are extremely difficult to distinguish from those of 
H. Forsteriana, which has been figured at t. 7018 of this 
work under Kentia, and has there been referred to the 
species Belmoreana. The pinnae of the true 77. Bel- 
moreana, however, converge upwards, while those of 
//. Forsteriana are drooping and proportionately broader, 
thus giving the two species a very different appearance. 
In addition to this II. Belmoreana does not attain so 
large a size before it flowers as II. Forsteriana does. In a 
letter addressed to Kewin 1892 Mr. Charles Moore called 
attention to the difference in the fruiting spikes of the 
palms, those of II. Belmoreana being twice as long as 
those of II. Forsteriana, solitary to their respective sheaths 
and in appearance unisexual, whereas in II. Forsteriana 
the spikes are several united at the base within a common 
sheath, each spike being manifestly 2-sexual. The 
apparently unisexual nature of the spike in II. Belmoreana 
is, however, deceptive and is due to the length of time 
which elapses between the maturing of the male and the 
female flowers respectively. In each trio of flowers 
along the spike the two male flowers first appear in 
close contact, the female flower which is situated between 
each pair of males being then but slightly developed and 
deeply seated in the pit of the spadix. The male flowers 
readily disarticulate and give place to the slowly 
developing female one. The introduction of H. Bel- 
moreana to cultivation in this country took place in 1872, 
and it has since been as extensively cultivated as an orna- 
mental plant as its ally H. Forsteriana. The plant from 
which our figure has been prepared was purchased when 
small from Messrs. F. Sander and Sons, St. Albans, and 
has grown along with H. Forsteriana, in the Mexican 
House at Kew. Both palms require an intermediate 



temperature ; their suitability for use as decorative 
plants is due to the fact that they bear rough usage better 
than most palms. They are both raised from seed 
imported from Lord Howe Island.

The history of this Orchid is somewhat singular. In 1908 
a large clump of Bulbophyllum Ericsson ii, Kranzl., from the 
collection of the Hon. Walter Rothschild was purchased 
for the Kew collection. Since then it has produced 
flowers on various occasions ; these have agreed with 
the description of B. Ericssonii by Dr. Kranzlin in the 
Gardeners' Chronicle in 1893, arid with the figure of 
that species at t. 8088 of the present work from a plant 
belonging to the collection of the late Sir Trevor 
Lawrence. In July, 1916, however, the clump produced 
a different inflorescence, which showed that it includes 
a second species, so similar in habit to B. Encssonn 
that its presence had remained unsuspected. The figure 
now published was prepared from the inflorescence in 
question, and its comparison with our t. 8088 will show 

April-June, 1918. 



how close is the general resemblance of the two species. 
Information kindly supplied by Messrs. Sander and Son, 
St. Albans, indicates that all the plants of B. Ericssonii 
now in cultivation belong to the original importation by 
that firm in 1893, and suggests that B. Ericssonii has 
only been collected once. The history of B. sociale, now 
figured, may therefore be regarded as identical with that 
of B. Ericssonii which was forwarded to Messrs. Sander 
from Bencoolen, on the western coast of Sumatra Its 
locality should therefore be somewhere in the district in 
which Rafflesxa Arnoldi was discovered. The collection 
made in this district by Sir Stamford Raffles and his 
friends Messrs. Arnold and Jack was lost in 1824 owing to 
a fire at sea. No serious attempt has ever been made to 
replace it, and very little is known of the flora of the dis- 
trict in which B. Ericssonii and its companion, B. sociale, 
appear to have been obtained. The species with which 
B. sociale appears to be most comparable is B. galbinum, 
Ridl., a native of the Malay Peninsula, which, however, 
has spreading, not converging, perianth-segments. At 
Kew B. sociale is grown in a tropical house, and does well 
under the cultural treatment suitable for B. virescens, 
J. J. Sm., and other Malayan species.

Stylus 6 mm. longus, gracilis ; stigma depresso-capitatum. — J. Hutchinson. 



The handsome Primula here described is very closely 
allied to P. sino-mollis, Balf. f. & Forr. From a series 
of specimens of that species communicated to Kew by 
Professor Bayley Balfour it differs most markedly in its 
much shorter corolla-tube which scarcely protrudes 
beyond the tips of the calyx-lobes. According to a letter 
from Professor Balfour, P. sylvicola, as the name implies, 
grows in woods, whilst P. sino-mollis favours pastures. 
P. sylvicola was collected by Mr. G. Forrest in Western 
China, and seed sent by him was first raised by 
Messrs. Wallace and Company, Colchester, from whose 
establishment the plant now figured was obtained by 
Kew in 1916 under the name here published. This plant 
flowered in a greenhouse in March, 1917, and ripened seed 

April-June, 1918. 



from which a stock has been raised. The species appears 
to be short-lived under cultivation and is best treated as 
a biennial. The flower-spikes reach a height of about 
two feet, and as the whorls of flowers develop in slow 
succession the plants remain in blossom for about three 
months in spring. At Kew this species is too tender for 
cultivation out of doors. 

Description. — Herb, rootstock fleshy. Leaves spreading or drooping, long- 
stalked, oblong-elliptic, apex rounded, base cordate, 3J-5£ in. long, 2|-3 in. 
wide, coarsely crenate, the lobes minutely crenulate, thinly papery, dark-green 
above and finely setulose, beneath yellowish - green and usually crisply 
puberulous on the nerves and veins ; lateral nerves about 8 along each side 
the midrib, the basal pair slightly recurved, all leaving the midrib at an angle 
of about 45°, and all raised beneath ; venation laxly reticulate ; petiole up to 
6 in. long, reddish-purple, crisply pilose. Flowers disposed in racemes of 
whorls ; common scape reddish, pilose ; whorls about 6-flowered ; pedicels up 
to 1\ in. long, pilose ; bracts subulate-lanceolate, up to | in. long. Calyx 
turbinate-campanulate, outside pilose ; tube | in. long, lobes lanceolate, acute,

The genus Melicytus comprises five or six species all 
of which, excepting that here figured, are restricted to 
New Zealand and the neighbouring islands. M. ramifloru.% 
originally discovered during Cook's first voyage, 1768-71, 
occurs in both the North and South Islands of New 
Zealand, in Stewart Island and the Kermadec Islands, 
and is everywhere abundant up to an elevation of 
3,000 feet. It was collected in the island of Eua, Tonga 
Islands, by Mr. J. J. Lister. Miss L. S. Gibbs, during 

April-June, 1918. 



her visit to the Fiji Islands in 1907, found it at Nadari- 
vatu, Viti Levu, at an elevation of 2,700 feet. It has 
been recorded from Norfolk Island, but the material 
from this locality, collected by A. Cunningham, Milne 
and Backhouse, and preserved in the Kew Herbarium, 
does not quite agree with that from New Zealand. The 
Norfolk Island plant was described as Hymenanthera 
oblongifolia, A. Cunn. (Hook. Lond. Journ. Bot. vol. i. 
p. 124) in 1842, and this has been identified, but certainly 
not correctly, with //. dentata, R. Br. It is evidently a 
Melicytus and must be very closely allied to M. ramiflorus. 
The material for our figure was communicated by the 
Rev. Arthur T. Boscawen of Ludgvan Rectory, Long 
Rock, Cornwall, the fruit in November, 1916, and the 
flower in June, 1917, from plants cultivated in the open 
raised from seed received from New Zealand in 1907. At 
Ludgvan the plant has withstood ten degrees of frost 
without serious injury. The species, which was intro- 
duced into England in 1822, is represented at Kew by 
plants in the Temperate House, one of which is planted 
™\ m /? rdinar y g ar den soil, and is now a bush about 
10 feet high. Flowers are occasionally produced at Kew, 
but not fruit. r

Sophora japonica was introduced to this country from 
China in 1753 by James Gordon, a nurseryman of that 
time at Mile End. It is not believed to be indigenous 
to Japan, although much cultivated there. Five trees 
of the original introduction were planted at Kevv, one at 
least of which remains. The Sophora is one of the most 
ornamental of all hardy trees. Its foliage is elegant and 
richly luxuriant, and flowering as it does in September 
when no other large tree is in blossom, its beauty is very 
conspicuous. It does not as a rule flower until it is 
thirty to forty years old, and is always seen at its best 
after a hot summer. The pods are rarely developed in 
England; the only time we have seen them in recent 
years was in 1911. Even then the seeds do not ripen, 
Jult-Sbptbmbbe, 1918. 



although they do so in Central and Southern Europe. 
Every part of the tree is permeated with a cathartic 
principle. The tree likes a rich loamy soil and should 
be planted in full sun. If we exclude the Edwardsia 
group of SopAora, which is confined to the Southern 
Hemisphere and is well distinguished by the erect, nearly 
uniform petals and small, more numerous leaflets, 
S.japonica is distinct from all other species cultivated in 
this country in being a tree. S. a/finis, Torr. & Gr., a 
small North American tree, differs in its axillary racemes 
and its 4-8-seeded pubescent fruits. 

Description.- Tree, 50-80 ft. high, the bark of the trunk much fissured in old 
specimens ; branchlets bright brown, more or less pubescent, especially when 
young. Leave* deciduous, alternate, imparipinnate, 6-10 in. long; rachis 
piabegcent, swollen at the base. Leaflets 9-15, ovate, acute, apiculate, rounded 
at the base, 1-3 in. long, |-§ in. wide, dark glossy green above, glaucous and 
furnished with adpressed pubescence beneath ; petiolules -^ in. long, pubescent ; 
stipules sickle-shaped, j in. long, caducous. Panicles terminal, pyramidal, 
4-8 in. high and wide. Flowers creamy white, f in. long, opening in 
September. Calyx campanulate, with five shallow triangular teeth, minutely 
pubescent. Corolla papilionaceous, the standard petal broadly cordate with a 
short claw, faintly lined with purple ; keel § in. long. Stamens ten, variable 
in length but all enclosed in the keel-petals. Pod 1-2 in. long, glabrous, 
1-4-seeded, very much constricted between the seeds. See, U dark brown, 
kidney-shaped.

The Ramondia here figured is a pretty plant for the 
rock garden. It bears a close general resemblance to the 
well-known R. pyrenaica which, however, is usually more 
robust in growth and has larger flowers with yellow 
apiculate anthers. Its distribution 'is particularly inter- 
esting. While the original 11. pyrenaica and the four forms 
-for they are really nothing more— of that species which 
have been regarded as distinct by Jordan, occur only in 
the Iberian Peninsula, extending as far south as the 
Province of Jaen in Spain, all the other European 
Gesneriaceae, comprising Ramondia serbica, R. Nathahae, 
Pane. & Petrov., R. Ilehlreichii, Janka, Haberlea rhodo- 
pensis, Friv., with its variety virginalis, and If. Ferdinandi- 

July-Septkmukk. 1918. 



Coburgii, Urumoff, are confined to the Balkan Peninsula 
and Thessaly (Mount Olympus). R. serbica was originally 
discovered on Mount Zlot in Southern Serbia by Pancic, 
growing on rocks in calcareous soil. It has since been 
found in other parts of Serbia and in Albania, but, as 
pointed out by Adamovic, the specimens from Albania, 
collected by Baldacci, have been distributed and recorded 
under the name of R, Nathaliae. The record for Bulgaria 
by Velenovsky is shown by Derganc to be based on an 
incorrect identification, the plant supposed to have been 
Ramondia serbica being in reality Haberlea rkodopensis, 
II. Nathaliae, regarded by some authorities as merely a 
variety of R. serbica, is, according to Adamovic, a distinct 
species, differing in having broadly ovate leaves which 
are narrowed almost equally to base and apex, regularly 
tetramerous flowers, a patelliform corolla and longer 
anthers. R, serbica has long been in cultivation at Kew, 
where it is established along with R. pyrenaica in a loose 
stone wall in the Rock Garden, thriving well in a shaded 
situation and flowering annually during May and June. 
A few plants are also grown in a cold frame to flower 
earlier in the Alpine House. It may be propagated by 
its seeds, which ripen freely. The plant from which our 
figure has been prepared was communicated by Sir F. W. 
Moore from the Royal Botanic Garden, Glasnevin, in 
June, 1917. 

Description.— Herb, small, stemless, perennial. Loaves rosulate, spathulate

The striking Gongura here figured is one of the plants 
which formed part of the collection of the late Sir Trevor 
Lawrence, presented to Kew by the late Lady Lawrence 
in 1914. This particular plant bore no name and no 
indication of its origin. When it subsequently flowered 
at Kew it was not possible to identify it with any named 
specimen, though it was found to match so closely an 
unnamed one belonging to the herbarium of the late 
Consul Lehmann as to leave little doubt that the two are 
forms of one species. The Lehmann specimen was 
collected in 1899 on the banks of the Timbiqui in the 

•J DXiY-SbPTBMBBB, 1918. 



forests of Cotejo, Colombia. There are several species 
of the genus Gongvra only known from the descriptions 
written by the late Professor Reichenbach. The plant 
now described cannot be identified with any of these, 
and it is therefore regarded as a new species for which 
the name G. latisepala is employed with reference to its 
relatively broad sepals. It bears a certain resemblance 
to G. (jratulabunda, Reichb. f., figured at t. 7224 of this 
work, but in addition to having sepals of a different 
shape that species may readily be distinguished by the 
absence of the pair of short horns at the base of the 
hypochile of the lip, a character of some value in this 
genus. In the possession of these horns our species 
comes nearer to G. odoratissima, Lem., which, however, 
has longer and narrower unspotted sepals. At Kew 
G. latisepala thrives well in the tropical house under the 
conditions suitable for its congeners and for the species of 
Stanhopea.

compressed, slightly sulcate, 12-2 in. long, f-1 in. wide, clothed with ovate

According to Messrs. Rehder and Wilson Rhododendron 
argyrophyllum, Franch., "is one of the commonest species 
in Western Szechuan and shows much variation." The 
material of this species in the Kew herbarium bears out 
this statement. But the variations are confined to 
single organs and are somewhat inconspicuous. They 
are simple morphological fluctuations, readily recognis- 
able, but not of specific importance. The authors cited 
have accorded the rank of varieties to two of these 
fluctuations: cupidare, with rather smaller cup-shaped 
flowers; and omeiense, with slender drooping pedicels 
and a rather darker indumentum on the leaves beneath. 
Both of these varieties agree with Mr. Franchet's 

July-September, 1918. 



original type in having hairy filaments ; that now figured 
differs from all three in having the filaments without 
hairs. This is a difference which, in the genus Rhodo- 
dendron, usually is specific; in the present instance 
it certainly does not possess that value. There is 
within 1L argyrophyllum a fifth recognisable form, 
collected by Mr. Wilson on Wa-shan {Wilson, n. 1210), 
which has glabrous filaments like those of var. humdrum, 
but has some of its calyx-lobes over one-third of an 
inch in length. The nearest ally of 1L argyrophyllum is 
A. hypoglaucum, Hemsl., described at t." 8649 'of this 
work, where the close relationship of the two species is 
discussed. The plant from which the flowering branch 
now figured was cut on 5 May, 1916, was raised from 
iono re ^ lved from the Arnold Arboretum and sown in 
iqaq u ™ SGed Was collected in Western Szeohuan in 
lyuh by Mr. Wilson and was received as his n. 1353. 
inis number, however, belongs in part to R. Wiltonii, 
Memal. & Wils., and it may be that in some collec- 
n m urj' ar M ro P h y llam var. leiandrum bears the name 
k IT^' , The P lants at Kew ar © rounded, much 
branched bushes, now about afoot and a half to two feet 
High slow of growth and sturdy. The species is appa- 
rently very hardy and did not suffer in the least from 
the severe winter of 1916-17. The flowers do not open 
until late April or early May, and thus have a better 
chance of escaping injury from late spring frosts than 
those of many ot the new Chinese species.

Govenia tingens, the subject of our illustration, was 
originally described and figured by Poeppig and Endlicher 
in 1838 from material collected in the dense forests of 
eastern Peru at Cuchero and Pampayaca. A specimen 
collected at Chacapoyas by Matthews is probably iden- 
tical with the original plant, and examples of a Govenia 
introduced from Peru by Messrs. Sander and Sons, St. 
Albans, through their collector, Forget, which flowered in 
February, 1915, were tentatively referred to G. tingens. 
The genus Govenia is a very natural one, most of the 
members of which are extremely similar in habit ; indeed, 
Lindley has remarked that among the genera of Orchids 
there is not one whose species are so difficult to distinguish 
from each other. In a dried state they are so much 
alike if the specimens have been similarly prepared, or 
they may vary so much in appearance, owing to the 

July-September, 1918. 



manner in which their flowers shrink, when they have 
been prepared differently, that their recognition is at 
times hardly possible. One result of this has been that 
the Peruvian G. tingens has been actually recorded from 
Caracas, a statement that is at least doubtful, because 
there is a species from Caracas, described by Lindley as 
G. fasciata, -which is clearly distinct from G. tingens. 
The chief difficulty connected with G. tingens lies in our 
imperfect knowledge of the original plant. The specimen 
figured was taken from a plant purchased for Kew in 
1912 at a sale held by Messrs. Prothero and Morris, the 
floral details of which agree well with the original figure. 
The plant is grown in a tropical house along with species 
of Calanthe, and flowers in early spring. It is most readilv 
comparable with G. Gardner i, Hook., figured at t. 3660 
of this work.

The specimens on which the original account of Luuun 
elegans was based were collected on Mount Parnassos by 
Sprunner, who suggested the name it bears, and on 
Mount Olympus by Heldreich. It occurs, however, 
elsewhere in Greece, and has been gathered on Mount Ida 
in Asia Minor. Before Boissier published his description 
under Sprunner's name, it had also been met with by 
Aucher, who suggested for it the name L. iberidifulM, 
which was similarly taken up by Planchon. Besides the 
specimen to which Aucher gave that name, this collector 
had also gathered it on Mount Athos, and Planchon, 
when he monographed the genus in 1848, after having 
referred to the Mount Athos plant under L. caespitosum, 
Sibth. & Sm., finally decided, and with reason, that it

too may be included in the present species. The nearest 
allies of L. elegans are L. jiavum, Linn., a species which 
is to be met with in south-eastern Germany and southern 
Russia, and L. camj>anulatuni,Limi., a species confined to 
southern France. From the former our plant differs in 
its smaller leaves, from the latter in its smaller flowers. 
The plant from which our figure has been prepared was 
presented to Kew by Miss Willmott, from her garden at 
Warley Place, Great Warley. It is not yet possible to 
say whether it will prove hardy at Kew. It flowers 
freely in May in a frame, but does not ripen its seeds. 
It can, however, be propagated readily by means of 
cuttings.

Alnus firma is a variable species which is widely dis- 
tributed in Japan, and with A. Alnobetuln, Hartig 

•Tulv-Septkmtikk, 1918. 



{A. viridis, Regel), belongs to the section of the genus 
characterised by having the female inflorescences in 
terminal racemes, which make their appearance in the 
spring, while in all the other known species they are 
solitary or racemose in the axils of the leaves and appear 
in autumn. A.firma is moreover easily recognised by its 
leaves having numerous straight almost parallel lateral 
nerves, which in the variety mult inertns are as many as 
18 to 24 on each side of the midrib. In this respect 
the leaves much resemble those of some hornbeams. 
Though sometimes found as a bush, at others it appears 
as a small tree, having long, slender, spreading branches, 
which give a graceful effect. A tree at Kew has now 
reached the height of nearly 30 ft., and has a trunk 
about 6 inches in diameter. Three varieties have been 
distinguished, each by some authorities regarded as 
species. The variety mukinervis (A. penduta, Matsu- 
mura) has longer, more acuminate, doubly serrate leaves 
with 18-24 pairs of lateral nerves, and smaller cones in 
a pendulous raceme. This was the first representative 
of the species introduced into this country, it is believed 
by Mr. John Gould Veitch in 1862. The variety 
Sieboldiana (A. Sieboldiana, Matsumura) has solitary cones, 
which are larger than in the other varieties ; its leaves 
are broader and fewer-nerved than in the variety 
multinerris, and its young branchlets, which are pube- 
scent in the variety Yasha, are glabrous. A. ftrma var. 
Sieboldiana is not in cultivation. The variety now figured 
was introduced into America by Professor Sargent in 
1892, and through him to Kew in 1893. At Kew it 
thrives well and makes a very elegant small tree, very 
distinct owing to its handsome, hornbeam-like leaves. 
It enjoys a deep, stiffish, loamy soil. Professor 
Matsumura records it from many localities in the island 
of Hondo, from one in Sikoku and from three provinces 
in Kiushiu. Its Japanese name is Oba-minebari. It is 
presumbly of this variety that Professor Sargent speaks 
in his "Forest Flora of Japan" as " largely planted 
along the margins of rice-fields near Tokyo to afford 
support for the poles on which the freshly cut rice is 
hung to dry." It has hitherto been quite a rare tree in 
English collections, but it well deserves attention and 



ought soon to be more frequently seen as it produces 
seeds plentifully at Kew. 

Description. — Shrub or small tree, reaching 30 ft. in height ; branches very 
long, slender, spreading ; twigs with numerous conspicuous lenticels, at first 
pubescent, at length becoming glabrous ; buds sessile, long-conical. Leaves 
petioled, ovate-lanceolate, acute or shortly acuminate, base rounded and often 
slightly unequal, thick-serrulate, glabrous above, adpressed-pubescent on the 
nerves beneath, 2^-3 in. long, 1-1} in. wide above the base; lateral nerves 
10-16 on each side of the midrib, conspicuous, nearly paralled, sunk above like 
the midrib, raised beneath ; petiole often nearly £ in. long, pubescent. Male 
catkins solitary or in pairs, terminal or nearly so, cylindric, 2-2J in. long ; bracts 
peltate, fa in. long, fa in. wide, glandular, ciliate, brown and membranous at 
the tip; bracteoles 2, minute, closely adpressed to the bract. Perianth 
4-lobed ; lobes minute, beset with a few yellow stalked glands. Stamens 
usually 4. Female catkins (strobiles) produced in spring in erect terminal 
racemes of 2-5 together, when in flower ellipsoid, J-J in. long, with thick, ovate 
bracts ; when in fruit solitary or in pairs, rarely more than 2, ovoid-ellipsoid, 
about J in. long, over } 2 in. wide; peduncles up to i in. long. Nutlets with a 
membranous wing, often obliquely obovate, emarginate, J-$ in. long, fa-fa 
in. wide at the tip.

We are indebted for the material from which the 
figure in the accompanying plate has been prepared to 
Sir Edmund Loder of Leonardslee, Horsham, who 
supplied the flowering spray on 12 June, 1917, and the 
fruit during the following November. Save for the 
specimens thus gathered from the plants at Leonardslee, 
Stewartia serrata is only represented in the Kew herbarium 
by a single leafy spray and a solitary detached flower, 
both collected in Japan in 1863 by the late 3lr 
Maximowicz. From the cultivated form now iigured 
Maximowicz's specimen differs in having the petals 
velvety outside on the upper half, and in having the 
shoot quite glabrous, as also are the leaves except lor the 
axil-tufts of tomentum beneath. In all other respects 
the two specimens appear to agree. We have failed to 
ascertain at all definitely the dimensions this btewarttq 

Jdly-Septembek, 1918. 



is capable of attaining. Maximowicz states that it had 
been reported to him that it may reach a large size : 
"arbor dicitur altissima, 4 pedes usque crassa." In 
spite of this, however, we believe it will never become 
more than a small tree in this country. It seems to be 
quite hardy both at Leonardslee and at Kew, and like 
its allies will no doubt thrive well elsewhere in either 
loamy or peaty soil. In the absence of seeds it may be 
propagated by cuttings made of fairly firm wood in July 
or August. The nearest ally of S. serrata is probably 
S. sinensis, Kehd. et Wils., a Chinese species first dis- 
covered by Professor A. Henry, and first introduced to 
cultivation by Mr. E. H. Wilson in 1901. This species, 
however, is readily distinguished from S. serrata by its 
pilose ovary, its monadelphous stamens and its leaves 
without pubescence in the axils of the veins on the 
undersurface. 

Description.— Tree, as cultivated in this country of small size ; young 
shoots pilose, finally glabreseent. Leaves deciduous, elliptic or obovate, acute 
to acuminate, base cuneate, margin serrate with the teeth incurved, 1J -3 in.

The Polystachya here figured is an unusually showy 
member of its large and somewhat polymorphic genus. 
Within that genus it belongs to a small group of species 
the original representative of which is P. elasttca, Lindl., 
but which is now known to include, in addition to 
P. Pobeguinii described above, two other forms from 
tropical' Africa, P. liberica, Rolfe, and P. Smythaana, 
Rolfe. The species which forms the subject of our plate 
was discovered by Mr. Pobeguin in the peninsula ot 
Ninkan and again at Labe in French Guinea, and was 
described from this material as Epiphora Pobeguinii by 
Mr. Finet, who took the opportunity thus ottered ot 
suggesting the restoration of the genus Epiphora based 

July-September, 1918. 



by Professor Lindley on the South African species 
described at t. 5S86 of this work as P. pubescens t Reichb. f. 
There is, however, no outstanding character by which 
Epiphora can be generically distinguished from Poly- 
stachya, and even if this had been the case there is the 
further difficulty that the present species is not very 
closely allied to P. puttescens, but belongs to another 
section of that rather variable genus. The species is 
reported to have been in cultivation at Paris from the 
original specimens. The plant now figured was obtained 
for the Kew collection from Messrs. Sander and Sons, 
St. Albans, and flowered at Kew in October, 1913. 
Another example of P. Pobeguinii flowered at Glasnevin 
in November, 1917. The species is remarkable for its 
bright rose sepals and petals and for its strongly recurved 
hp which has a darker purple front lobe, and a prominent 
cushion-like, bright yellow crest on the disk. It thrives 
in a tropical Orchid House if planted in a mixture of 
peat fibre and sphagnum. It should be kept dry when 
not in active growth.

The graceful St. John's Wort here delineated was first 
discovered by Kotschy in 1841 near Diarbekir. Since 
then the species has been met with by Lorent, Hauss- 
knecht and others in the Orient, where it inhabits a 
somewhat limited area which extends from Aintab and 
Nisib in Northern Syria to Kharput and Diarbekir in 
Kurdistan. Within this area it is said to grow chiefly 
on calcareous soil. The colour of its flower varies, 
sometimes in the same locality, from rich yellow to pure 
red or nearly scarlet. Haussknecht, who collected both 
colour-forms at Aintab and Nisib, was inclined to attri- 
bute the colour of the red form, which we now figure, to 
the ferruginous nature of the loam in whioh he found it 
growing, though when describing the yellow form ^as 
Hypericum laeve, he and Boissier nevertheless accorded 
the red one the status of a variety, while Hochstetter 
treated specimens of the red flowered plant, collected by 

July-September, 1918. 



Lorent, as a distinct species, 1L rubrum. There is, 
however, no character other than the colour of the 
flowers by which the two can be distinguished, and we 
have therefore reverted here to what would seem to 
have been the view taken by Haussknecht when he 
examined the two plants as they grew under natural 
conditions. The plant which forms the subject of our 
plate flowered in the collection at Kew in June, 1917. 
It was obtained from Messrs. Bees, Limited, of Neston, 
who exhibited it in flower at the Holland Park meeting 
of the Royal Horticultural Society in June, 1914. With 
Messrs. Bees, at Sealand, Cheshire, the plant withstood 
two successive winters and grew to a height of eighteen 
inches, but at Kew it has proved to be tender and has 
died after flowering. Though it continues in flower for 
about two months, it has failed to ripen seeds at Kew, 
but it has been successfully propagated by means of 
cuttings made from young snoots. The yellow-flowered 
form, regarded by the authors of the species as the 
typical one, has not yet been introduced to English 
gardens. The nearest ally of II. laeve is the Arabian 
ILscibrum, Linn., from which our plant is readily distin- 
guished by its smooth and glabrous, in place of rough 
and glandular stems. 

DBSCBIPTIOK.— Herb, perennial, sending up several stems, in wild plants 
1-2 ft. in height; stems terete, virgate, smooth and glabrous, with many 
axillary branchlets. Leaves linear or on the stouter stems linear-oblong, 
obtuse, usually and especially on the twigs with revolute edges, dotted with 
transparent glands, J-f rarely 1J in. long, t l_i i n . w id e , those of the twigs 
owing to their much revolute edges often under j 5 in. across. Panicle shortly 
ovoid, rather corymbose and dense, very rarefy elongated and more open; 
bracts ovate-oblong or oblong, dotted with black glands. Sepals elliptic-oblong 
or ovate-oblong, somewhat obtuse, glandular-crenulate with black glands, 
fr^S in. long. Petals spreading, elliptic or oblong-elliptic, shortly clawed, 
towards the apex shortly fringed with black glands, l-\ in. long, golden-yellow, 
or yellow with a reddish tinge or, in the form figured, scarlet-red, as are the 
filaments and the styles.

The very attractive Scabiosa now figured was raised 
from seed presented to Kew by Mr. A. K. Bulley in 
1915. This seed had been obtained in Bhutan by 
Mr. Cooper when collecting there on behalf of Messrs. 
Bees, Limited. This species, S. Hookeri, was first col- 
lected by the late Sir J. D. Hooker in July, 1849, in the 
Sikkim Himalaya near Tungu at altitudes of 12,000- 
14,000 feet above sea-level. It was met with again by 
Mr. H. J. Elwes in 1877, and since then it has been 
gathered in the vicinity of Ta-chien-lu in Western 
Szechuan by various French and British collectors. 
This is by far the most handsome of the speoies of 
Scabiosa met with in the Himalaya, and is readily 

July-September, 1918, 



recognised among them by its radical leaves, and its 
leafless, scapigerous one-headed peduncles. At Kew it 
has flowered in an open border in July and has proved 
quite hardy, making vigorous growth in spring after a 
winter, unprotected, out-of-doors. What appears to be 
another form of the species with light yellow flowers has 
been gathered in the neighbourhood of Chumbi, immedi- 
ately to the east of Sikkim, by one of the collectors 
employed by the late Sir George King. The same form 
has also been found near Lhassa in Tibet by Captain 
H. J. Walton.

THE long l,f e of Sir Joseph Hooker, which began exactly 
one hundred years ago, covers the whole of the scientific 
renaissance. Pre-eminent in botany, his name will always be 
associated with the making of Kew ; but as Traveller and 
Explorer he was hardly less eminent. The history of his 
scientific career is also the history of many friendships, revealed 
m his unceasing correspondence, most of all with Charles Darwin, 
for he was Darwin's confidant, helper, and critic for fifteen years 
before the " Origin " appeared.

The very distinct Rhododendron now figured is a native 
of Western Szechuan, where it occurs at altitudes ot 
9,000-10,000 feet above sea level. It was first collected 
near Moupine, in 1869, by the Abbe David who, noting 
it as remarkable for its rounded leaves, used tor it the 
name /?. rotundifolium published, but without a lull 
description, in 1873. In 1877 Professor Decaisne sup- 
plied an account of the plant under the name ^***™'"» 
and although the late Mr. Franchet took up the Abbe s 
Ootobee-December, 1918. 



name in 1888, that of Deeaisne has, with reason, been 
definitely adopted by Messrs. Render and Wilson. The 
species was first introduced to cultivation in this country 
by Messrs. J. Veitch and Sons from seed obtained for them 
by Mr. E. H. Wilson in 1904. It is, however, compara- 
tively rare in gardens, owing to the circumstance perhaps 
that it did not thrive very well at Coombe Wood, so that 
the stock in the country was for a time somewhat scanty. 
Two plants were obtained for Kew from the Coombe 
Wood nursery in 1908, and although they have proved 
hardy in so far that they have not been injured by 
winter cold, they have not thriven well. They have 
flowered occasionally, and have ripened seeds from which 
plants have been raised, but after ten years they still 
remain small and stunted. The species, however, is 
well adapted to the milder damp climate of the south- 
west of England, and in the collection of Mr. J. C. 
Williams at Caerhays Castle it forms rounded bushes 
over five feet through, many of which thrive well when 
given a rather open well-drained situation facing the 
east. The first plant to flower at Caerhays did so on 
April 20, 1910, and Mr. Williams, to whom we are 
indebted for the material for our plate from a plant that 
blossomed at Caerhays in 1914, regards R. orbiculare as 
one of the most remarkable of the Rhododendrons 
obtained by Mr. Wilson. " I think," he writes, " I would 
prefer to keep a good plant of it if I were only to be 
allowed one of the whole family." Mr. Williams, in the 
same letter, says, " Wilson told me he found it with his 
glasses on the far side of a deep valley, and that it took him 
a day and a half's journey to get there." From Caerhays 
seeds of R. orbiculare have been distributed freely, while 
the species has also been propagated there by the slower 
process of establishing cuttings. In addition to this 
R. orbiculare has been crossed with R. discolor, Eranch. ; 
the hybrids have flowered, and although no improvement 
on R. orbiculare they much resemble that parent and are 
more robust. The species is readily distinguished from 
other known Chinese ones by its suborbicular, deeply 
cordate leaves borne on unusually long petioles. Its 
nearest ally is R. Fatyesii, Franch., figured at t. 8736 of 
this work, which differs mainly in its leaf characters. 



Description. — Shrub, 9-10 ft. high ; twigs stout, shining, glabrous, laxly 
leafy towards the tip ; axillary buds narrow-ovoid, obtuse or somewhat acute, 
glabrous. Leaves elliptic or elliptic-orbicular, sometimes slightly emarginate 
or mucronulate, deep cordate at the base with the lobes overlapping, 1-A in. 
long, H-3 in. wide, coriaceous, glabrous, green above, glaucous and finely 
veined beneath; midrib flat above, very conspicuous beneath, about T \,- in. 
broad at the base, becoming very slender near the tip ; lateral nerves about 
10 on each side, slender, branching towards the leaf-margin, inconspicuous 
beneath ; petiole stout, nearly cylindric, over 2 in. long, shining, glabrous. 
Inflorescence terminal, open, about 10-flowered. Flowers nodding, rose-car- 
mine ; pedicels 1-1$ in. long, glabrous. Calyx small ; lobes short, with glandular 
margins. Corolla wide-carapanulate, without scales; tube 1J in. long, 1£ in. 
wide at the mouth ; lobes 7, nearly erect or spreading, short, widely emarginate. 
Stamens about 13, unequal in length, rather shorter than the tube ; filaments 
glabrous, whitish ; anthers very dark brown, A in. long. Ovary 7-celled, beset 
with nearly sessile glands ; style little exserted, glabrous.

The little Mesembryanthemum here figured is a member 
of the Sphaeroidea section of the genus, characterised 
bv the leaves being reduced to a single pair, united to 
form a more or less globose or ovoid mass termed a 
- corpusculum." It is a native of Great Namaqualand 
where it was collected by the late Professor H. H. W. 
Pearson of Cape Town in the course of the Percy Sladen 
Expedition to the Great Karasberg Range. In its native 
habitat it grows on sandy plains at an elevation ot MOU 
feet above the sea. Living plants were presented to Kew 
by Professor Pearson in the early part of 1913, and naa 
not yet flowered when in June, 1914, a description of the 
species was published by Mr. N. E. Brown In October, 
1915, however, a plant flowered in the collection of suc- 
culents at Kew and admitted of the preparation of our 
illustration. The nearest ally of this Namaqualand plant 
is M. Lesliei, N. E. Br., a native of the Transvaal in which, 
however, the leaves are more completely confluent into

The small Mesembryanthemum now figured is a member 
of the section Cordiformia, based originally by Mr. A. 
Berger on M. bilobum, Mario th, but which is now known 
to include at least three other species: M. gracilipes, 
Bolus ; M. stylosum, N. E. Br., figured at t. 859ob of this 
work ; and M. Elishae, the species here described. The 
section is characterised by the very fleshy, somewhat 
elongated leaves being more or less united at the base 
but remaining free above so that the resulting corpus- 
culum is more or less heart-shaped. The precise habitat 
of this species in South Africa has not been recorded. 
It appeared originally in this country in the collection 
of Mr. G. Elisha, Canonbury Park Road, a keen cultiva- 
tor of species of Mesembryanthemum, The specimen here 
depicted flowered with Mr. Elisha in October, 1916, and 
was described by Mr. N. E. Brown. Since then Mr. 
Elisha has presented a plant to Kew. Mr. Brown has 
remarked that the nearest allies of M. Elishae are 
M. bilobum and M. stylosum, but it differs from both in 
its dwarfer and relatively shorter growths, which form

glaucous green with scattered darker dots of the half- 
connate leaves give it a pleasing appearance. The 
flowers are bright yellow, expanding in full sunshine and 
closing at night.

The example of Primula sinopurpurea which is here 
figured was raised at Kew from seed collected by Mr. G. 
Forrest in Yunnan and presented by Mr. J. C. Williams, 
Caerhays Castle, in 1915. It is closely allied to the rather 
widely distributed P. nivalis, Pall., figured at t. 1161 of 
this work, but differs from that plant in its more remotely 
repand-denticulate leaves, which are conspicuously farinose 
on the under side. In his memorable discourse on Chinese 
Primulas, addressed to the members of the Primula 

October-December, 1918. 



Conference held in April, 1913, Professor Bay ley Balfonr 
remarked that the group of forms of which P. nivalis, 
Pall., is the type includes no fewer than seven Chinese 
species, all of which, with the exception of P. albijios, 
Ward, have blue or purple flowers. Of these P. sino- 
purpurea is one of the most striking. It has proved 
quite hardy at Kew, where, planted in the Rock Garden 
in half-shade, it has grown well and flowered freely. 
The first examples to flower did so in April, 1916, and 
from one of these our figure was made. Examples which 
flowered in April, 1917, and again in April, 1918, haVe 
developed into specimens more robust than the original 
ones, with the flowers sometimes arranged in two whorls 
about a couple of inches apart, the upper whorl then 
producing as many as twenty flowers. In each season 
these plants have ripened seeds from which a new crop 
has been raised. Like some other Chinese Primulas, 
P. sinopurpurea must be treated as a biennial, for under 
cultivation the plants usually die after flowering. 

Description.— Herb, stout and frequently about 4 in. high, but sometimes 
larger and exceeding a foot in height. Leaves rosulate, ascending or spreading, 
oblanceolate, acute or subacute, narrowed at the base with a winged petiole, up 
to 8 in. long and If in. wide, thinly papery or almost membranous, repand- 
toothed, glabrous above, yellow and mealy beneath ; lateral nerves ascending,

We are indebted for the flowering spray and the fruit 
of Stewartia sinensis now figured to Mr. H. Williams Grigg, 
in whose grounds at Cann House, Crown Hill, near 
Plymouth, it forms part of a very extensive and exceed- 
ingly well cultivated collection of rare trees and shrubs. 
There are also young examples in the collection at Kew, 
where they thrive well and are evidently quite hardy, 
since they have remained quite unaffected by the 
rigorous winters of 1916-17 and 1917-18, though they 
do not grow with the luxuriance that characterises them 
in the softer air of South Devon. This species was 
originally discovered in Western Hupeh by Mr. E. H. 
Wilson in 1901 when collecting for Messrs. Veitch, by 

October-December, 1918. 



whom it was introduced to cultivation. It was distri- 
buted under the name S. monadelpha and is doubtless in 
cultivation under that name in various English gardens. 
The true IS. monadelpha, Sieb. & Zucc, is, however, a 
purely Japanese shrub and is readily distinguished from 
ft sinensis by its much smaller, scarcely angled capsules, 
which are only one-third of an inch wide. Another near 
ally of S. sinensis is S. serrata, Maxim., also a purely 
Japanese species, figured at t. 8771 of this work, which 
is even more readily distinguished from our plant by its 
polyadelphous stamens, its glabrous ovary, and its leaves 
with tufts of pubescence at the axils of the main-nerves 
on the under surface of the leaves. While still quite 
young all the species of Stewartia enjoy an admixture of 
peat with the soil in which they are grown, though this 
is not essential if the soil be light, warm and loamy and 
it it be free from lime. In the absence of seeds, the 
btewartias may be propagated by summer cuttings.

The attractive species now described is a native of 
Costa Rica. It was presented to the Kew collection in 
1913 by Mr. C. H. Lankester. Since its arrival it has 
thriven well in the Cactus House at Kew. It produced 
flowers for the first time in October, 1917, when the 
accompanying figure was prepared. The study of species 
of the Cactus family presents several difficulties. Owing 
to the trouble experienced in preserving them satisfac- 
torily they are, as a rule, but imperfectly represented in 
herbaria. Their determination from descriptions unac- 
companied by drawings or photographs is often some- 
what uncertain. Even where there are ample material and 
adequately illustrated descriptions, students of the family 
often are beset with doubts as regards the delimitation 
not only of the species themselves, but also of the genera 
to which they should be referred. In the present 
instance all the difficulties alluded to have been encoun- 

October- December, 1918. 



tered. There is no specimen in the herbarium at Kew 
with which our plant may be exactly matched. Although 
Mr. Lankester has not supplied any note as to the local 
name of this plant, we believe it to be that known in 
Costa Rica as the Tunilla, which is stated to bear an 
elongated, spinose edible fruit and fragrant flowers, and 
has been described by Dr. Weber as Cereus Tunilla. At 
all events the plant figured accords well with Weber's 
account of the Tunilla and still better, perhaps, with the 
description given by the same author of Cereus Gonzalezii, 
a closely allied one subsequently regarded by Professor 
Schumann as merely a form of the Tunilla. This verdict 
of Schumann has been accepted by Dr. Britton and 
Dr. Rose, though these authors have deviated from both 
Weber and Schumann in that they regard the Tunilla as 
the type of a distinct genus on which they have bestowed 
the name Weberocereus. Whether our plant really be the 
Tunilla or not, it accords so well in essentials with 
Cereus that we have felt it desirable to retain it in that 
genus. The original type of Cereus Tunilla was found 
growing on an oak in the village of Tablon near Cartago, 
at a little over 6,000 feet above sea-level; that of 
C. Gonzalezii was collected at Pacayo, at a similar 
elevation. If, as we believe, the plant figured be Cereus 
Tunilla, the present is not the first occasion of its intro- 
duction to European collections ; a young plant, grafted 
upon the Mexican Cereus nycticalus, Link, is reported to 
have blossomed at Paris in October, 1901.

stems, emitting a few aerial roots. Shoots rather slender, green, usually

Since the introduction, more than half a century ago, 
of 0. crispum, Lindl., orchid growers have found that, 
among their plants of repeated importations, occasional 
examples, on coming into blossom, prove to belong to one 
or another of three species other than 0. crispum. This 
is not surprising. Mr. Rolfe has shown (Orchid Review, 
vol. i. p. 277) that, in the district of Bogota in Colombia, 
O.ylonosum, Lindl. & Reichb. t, 0. LindUyanitm, Reichb. 
f., and 0. luteopurpureum, occur naturally in association 
with O. crispum, and the casual inclusion of one or other 
of the three in what was believed to be an unmixed 
parcel of 0. crispum is intelligible. What has been more 
puzzling to growers has been the occurrence among their 
plants of forms that on flowering proved to be unlike any 
of the four species named. Their intermediate characters 
suggested that such forms must be of hybrid origin, though 
their precise parentage has often been in doubt. When 
dealing with these hybrids Mr. Rolfe pointed out that 

October-Dkckmbkb, 1918. 



although they did not include a cross between 0. 
gloriosum and 0. Lindkyanum, an instance might be 
anticipated, and a plant which flowered in 1904 in the 
collection of Mr. W. Thompson, Walton Grange, Stone, 
exhibited characters that led Mr. Stevens, his gardener, 
to conclude that it must be this natural hybrid. The 
characters of the plant induced Mr. Rolfe to adopt the 
conclusion of Mr. Stevens and to describe the form as 
0. praevisum. In order to confirm the parentage of 
the supposed hybrid, an opportunity was taken to cross 
0. gloriosum and 0. Lindkyanum. Several seedlings, of 
which 0. gloriosum was the seed-parent, were secured, 
and the first of these to flower did so at Kew in March, 
1915, when our drawing was made. As compared with 
the natural hybrid, that now figured has a brighter yellow 
ground-colour, and shows more of the influence of the 
female parent. It is of interest to note that 0. Wilcke- 
anum, Reichb. f., a natural hybrid between 0. crispum 
and 0. luteopurpureum, and 0. Conrad inei, Reichb. f., a 
natural hybrid between 0. crispum and 0. Lindkyanum 
have now both been raised artificially; also that 
O.Adrianae, Lindl., a plant from another locality in 
Colombia, where 0. crispum grows in company with 
O. Hunnewellianum, Rolfe, has been shown by Mr. Rolfe 
from crosses effected at Kew to be a natural hybrid 
between these two species. Cultivated under the con- 
ditions suitable for its parents, 0. praevisum thrives as 
satisfactorily as they do.

The handsome Berberis here described and figured was 
purchased for the Kew Collection from Messrs. J. Veitch 
and Sons, Coombe Wood, in 1913. It had been raised 
from seed collected for the firm by Mr. E. H. Wilson in 
Western Szechuan, China, in 1904, and may be grown 
in various gardens under Wilson's seed-number, 1930. 
The Kew examples flowered for the first time in June, 
1914, and developed an abundant crop of its richly 
coloured fruits in the autumn of that year. Since then 
the plants have flowered and fruited freely, and now 
form bushes six to eight feet high. Being without a 
name, flowering and fruiting material of the species was 
sent to the Arnold Aboretum, where it has been examined 
by Dr. Schneider, who has described it as a new species, 
observing when so doing that " this is a very distinct 
species of which the taxonomic position is yet unknown." 

Octobee-Decembeb, 1918. 



As a shrub for gardens B. Beaniana promises to be one 
oi the most attractive of the many new Chinese bar- 
berys, especially as an ornamental fruit-bearer. It is 
evidently quite hardy ; its flowers are of a rich deep 
yellow and its fruits are of a fine purple and very 
pientriul. The seed it produces so copiously ought soon

The genus Diascia includes some fifty species, all of 
them natives of South Africa. Most of them are without 
horticultural value, and the only species, other than 
D. Aliciae here figured, known in European gardens is 
D. Barberae, Hook, f., which was introduced in lb/0 and 
is figured at t. 5933 of this work. The species now 
described was discovered in 1903 in the Kentam district 
of the Transkei by Miss Alice Pegler, who met with it in 
damp sheltered spots at about 1,500 feet above sea-level. 
The material for our plate has been provided by plants

raised at Kew from seed received in 1915 from the late 
Professor Pearson, Cape Town. Grown in an outside 
border during the summer, they flowered freely in 1916. 
At Kew the plant is not hardy and has not ripened seeds ; 
propagation is, however, easily effected by means of 
cuttings. Its nearest ally is D. Burchellii, Hiern, which 
also occurs in the Transkei but extends thence westward 
to near Caps Town ; this latter species has not yet been 
introduced, and is unlikely to prove more effective 
horticulturahy than that now figured, which as a decora- 
tive plant, although not without charm, is much inferior 
to the better known D. Barberae. If the flowers of 
D. Barberae and D. Aliciae be compared it will be 
observed that in both species the filaments of the lower 
and longer pair of stamens form a loop through which 
the two upper stamens are deflected, the anthers of the 
latter being thus placed on the lower side, the four 
being connivent or coherent round the tip of the style. 
But whereas in D. Aliciae the style and anthers are 
appressed to the upper lip across the sac at its base, in 
IK Barberae they are diverted towards the median lobe of 
the lower lip and stand between the mouths of the spurs.

No Mesembryanthemum to be met with in succulent col- 
lections is more handsome than the long known M. edule, 
figured here from material obtained by Mr. J. Hutchinson 
on the face of an old quarry at the entrance to Caerthilhan 
Valley in Cornwall, where it is thoroughly naturalised m 
company with the Australian and Chilian species M. aequi- 
laterale, Haw. A native of South Africa, M. edule, 
in most parts of Britain, requires the protection ot a 
greenhouse during winter. But in certain localities in 
Cornwall, South Devon and Jersey, it is now established 

October-December, 1918. 



as an alien, and in those parts of the United Kingdom 
with a similar climate the species is hardy and is seen to 
best advantage when planted along the top of a low wall 
and allowed to hang down. It thrives best if planted 
in poor sandy soil, and may be propagated with ease 
by cuttings taken at any season. The nearest ally of 
M. edule is another Cape species, M. acinaciforme, Linn., 
figured at t. 5539 of this work. The two 'are readily 
distinguished, when alive, by their differently coloured 
flowers and their differently shaped leaves. As seen in 
dried specimens, however, they are not always easily dis- 
criminated, and when Linnaeus enumerated both in 1753 
he regarded them as varieties of one species. Ten years 
later Linnaeus recognised the species now described as 
distinct, and this judgment has never since been chal- 
lenged. M. edule and M, acinaciforme, together with the 
somewhat similar M. aequilaterale which, however, is 
confined to the Pacific coasts of America and to Australia, 
but does not occur in S. Africa, were grouped by 
Haworth in the section Acinaciformia, which, as Marloth 
points out, differs from all other sections of the genus in 
bearing fleshy fruits— in the S. African species known as 
Zuurvygen or Hottentot figs— with numerous small seeds 
embedded in a subacid edible pulp ; in other sections 
the fruits are dry capsules. The cultural history of 
M. edule began long before it received that name. In 
173^ it was, as a figure by Dillenius shows, in the garden 
ot fcherard at Eltham. Moreover it was, as Dillenius 
knew, m the Breynian collection ; Breyn tells us it was 
in his garden in Holland in 1668.

than with other species of the genus. At Kevv the 
species is evidently perfectly hardy. It passed through 
the winter of 1916-17, notwithstanding the severity of 
the conditions to which it was exposed, with as little 
injury as any Chinese Rhododendron. At Caerhays 
Mr. Williams finds that the flowers have a considerable 
range of colour, the shades varying a good deal in value ; 
the form of the blossom varies also in individual plants. 
At Kew it flowers freely, and produces seed from which 
young plants have been raised. The most striking 
feature of R. oreotrephes is, however, the beauty of the 
foliage, due to the bloom on the underside of the leaves. 
In Cornwall, Mr. Williams remarks, the foliage of many 
of his plants is, at a particular stage of growth, among 
the most brilliant of any plant seen in the south-west of 
England, recalling the colour of the leaves of the sea- 
hollies. In the neighbourhood of London this character 
is far less striking. As yet none of the plants in cultivation 
nave attained the dimensions noted by Mr. Forrest for 
the wild plant in China. In situations otherwise suitable 
it is best planted on a slope, so that the glaucous hue of 
its young leaves may be seen from below. As a practical 
point, Mr Williams observes that rabbits eat this 
Rhododendron more than they do most shrubs.

Bulbophyllum Hamelinii was first found in Madagascar 
a quarter of a century ago. Living plants were sent by 
Mr. Hamelin to Messrs. Sander and Sons, St. Albans, 
and in 1893 a note in " Garden and Forest " (p. 336) 
detailed the leading features of the species— its large 
size, its curious pseudobulbs " like some great flat marine 
shell," its erect scape "thick as one's finger" and a foot 
and a half long, and the large number of flower-scars 
along the upper portion of the scape. When that note 
was written the flowers had not been seen, and it was 
not until August, 1902, that a plant acquired by the 
Royal Botanic Garden, Glasnevin, produced an inflores- 
cence which enabled a description of the flowers to be 
prepared. The note from Sir F. W. Moore which accom- 
panied this inflorescence indicated that the plant hardly 

Octobeh-Decejibek, 1918. 



fulfilled the expectations its size had led growers to form. 
This note refers to the disagreeable odour characteristic 
of this interesting plant, which is not closely allied to 
any other known BuXbophyllum, and is readily distin- 
guished from all the cultivated species by its obcordate- 
orbicular, compressed pseudobulbs, concave on one face, 
convex on the other, and closely flattened against the 
thick climbing rootstock. The Glasnevin plant of 
B. Hamelinii blossomed again in 1904. Another plant, 
obtained for Kew from Messrs. Sander, flowered for the 
first time in August, 1916, when our plate was prepared. 
In August, 1917, a third plant, part of the collection of 
the late Sir Trevor Lawrence, presented to Kew by 
Lady Lawrence in 1914, also flowered for the first time. 
Both Kew plants thrive well in a tropical house in 
baskets of peat and sphagnum suspended from the roof. 
They require abundant water whilst making their growth 
in autumn. Though B. Hamelinii has no near allies it 
resembles in its carrion-like odour the Bornean B. Beccarii, 
Reichb. f., figured at t. 6567 of this work. When the 
original consignment of B. Hamelinii reached this country, 
no precise habitat was recorded, but a fruiting specimen 
collected by Mr. Warpiy, which reached Kew in 1900, 
is noted as being from a forest at Tanabe.
