PREFACE 



Although important collections of plants had been made in 
western Szech'uan by the French missionary Armand David as 
early as 1870; the world knew -little of the remarkable beauty 
and richness of the flora of west central China until Augustine 
Henry, an officer of the Chinese Imperial Maritime Customs 
Service stationed at Ichang from 1882 to 1889, sent to England 
the dried plants which he had collected in western Hupeh. An 
examination of these collections, the first of which reached 
England in 1886, disclosed many new genera and a great num- 
ber of new species. Henry collected only herbarium specimens 
and a few lily bulbs, and took no steps to introduce into western 
gardens his remarkable discoveries. 

It was evident, however, that from no other part of the world 
could so many new plants suitable to adorn the parks and 
gardens of temperate climates be found as in western China; 
and in 1897 I advised the late James H. Veitch, at that time 
the Managing Director of the well-known nursery firm of James 
H. Veitch & Sons, of London, to send a collector to Hupeh to 
collect the seeds of Henry's interesting discoveries, and to make 
additional observations on the flora of that region. • 

Mr. E. H. Wilson, a student at the Royal College of Science, 
South Kensington, and previously a young gardener in the 
Royal Gardens at Kew, then twenty-three years old, was selected 
on the recommendation of Sir William T. Thiselton-Dyer for 
the undertaking. He left England on April 11, 1899, traveling 
by the way of Boston in order to visit the Arboretum, and then, 
after a short stay in Yunnan, where he went to confer with Dr. 
Henry, who was then stationed at Szemao, he reached Ichang 



VI PREFACE 

early in February, 1900. The next two years were devoted by 
him to collecting in the mountains of western Hupeh. From 
this journey Wilson returned to England in April, 1902, and 
went to China again in January of the following year with a 
special commission to collect Meconopsis integrifolia, found only 
in the alpine regions of the Thibetan border, which he now 
explored for the first time. During these two journeys Wilson 
sent to England the seeds of a large number of plants and many 
lily bulbs, and made a considerable herbarium. His work, how- 
ever, in western China, was not completed. Under instructions 
from Mr. Veitch, Wilson had paid attention only to 'plants of 
supposed horticultural value, and had neglected conifers and 
many other important plants almost entirely, no one then sus- 
pecting that on the slopes of the mountains which rise from the 
plains of China to the Thibetan plateau is probably the greatest 
aggregation of conifers in the world. 

It seemed desirable, therefore, that the work which Wilson 

had so well begun should be completed, and the Arboretum 
was fortunate in securing his services for another Chinese ex- 
ploring expedition. He left Boston on this journey on December 
31, 1906, and returned in May, 1909. This journey was very 
successful. He sent back seeds, often in large quantities, of 
more than 1000 species of trees and shrubs, many lily bulbs, 
the cuttings of willows and poplars, the roots of a few other 
trees and shrubs, an herbarium of about 50,000 sheets, and a 
collection of 720 photographs. In the autumn of 1908, when he 
was among the forests of conifers, these trees were not bearing 
cones. It was important that these trees should be introduced 
into the Arboretum, and in April, 1910, Wilson, for the fourth 
time, went to China for the purpose of carrying out this plan, 
returning a year later with large and valuable collections. 

In the Planiae Wilsonianae is found an account of the speci- 
mens collected by Wilson in these two journeys, with descriptions 
of new species and varieties, and the enumeration of several im- 
portant groups as they are represented in China. It is impos- 
sible yet to form an accurate opinion of the number of new 



PREFACE Vll 



species discovered by Wilson in his four journeys. It is safe to 
say that few travelers, however, have discovered as many new 
plants; certainly no other man has ever introduced so many 
woody plants of exceptional interest and value into cultivation. 
This will appear when it is realized that in the first volume of 



Wilsonianae 



Wilson 



are described two new genera, two hundred and twenty-five 
new species and one hundred and sixty-two new varieties of 
woody plants. In earlier publications have appeared descrip- 
tions of two new genera and about one hundred new species of 
woody plants discovered by Wilson in his first journeys. 

In the preparation of this work the Arboretum is indebted to 
a number of European specialists who have elaborated several 
different groups, and I take this opportunity to extend to them 

4 

the cordial thanks of the Arboretum.

Arbor excelsa foliis geminis rigidis 7-10 cm. longis, canalibus resini-

verticillatis, junioribus subterminalibus mucronatis, adultis 4-6 cm.

In many particulars this Pine resembles the previous species and ultimately 
may be united with it; the principal difference lies in its subsymmetrical cone and 
its possibly invariable number of fascicle leaves. The species is established on the 
representation of Mr, Wilson, who considers it entirely distinct from all the other 
Pines that he has seen in China. 



SAXIFRAGACEAE. 



PHILADELPHUS L. 

Determined by E. Koehne. 

Philadelphus subcanus Koehne in Mitt, Deutsch. Dendr. Ges, XIII. 
83 (1904). — Schneider, III Handb, LaubholzL I, 369 (1905). 

Western Szech'uan: Mupin, thickets, alt, 1500-2100 m., June 
1908 (No. 3039); Wa-shan, thickets, alt. 2100-2400 m., June 1908 
(No. 3040); southeast of Tachien-lu, thickets, alt. 1800-2300 m., 
June 1908 (No. 3042); Wa-ssu country, W^n-chuan Hsien, alt. 1800- 
2300 m., July 1908 (No. 3043). 

I formerly found the style pilose, but now I find it glabrous in some flowers of 
Wilson's specimens. 

Philadelphus subcanus, var. dubius Koehne, n. var. 

Hamuli floriferi etiam infra racemum laxe pilosi (in typo ibidem 
glabri). Folia subtus etiam inter nervos dense pilosa, interdum 
etiam supra pilosa. Stylus saepe glaber. 

Western Szech'uan: Pan-lan-shan, west of Kuan Hsien, alt. 
1500-2300 m., June 1908 (No. 3044); Min valley, Kuan Hsien, alt, 
900 m., June 2, 1908 (No. 3045) • 

By its leaves being pilose also on the upper surface this variety seems to ap- 
proach P. Magdalenae Koehne, but in that species the ovaries and sepals are brown- 
ish violet outside which I have never observed in P. subcanus. No. 3045 and 
part of No. 3044 have the leaves on the upper surface and the style glabrous, while 
one part of No. 3044 has the leaves above and the style at the base pilose.

Western Szech'uan: Wa-ssu country, Wen-chuan Hsien, alt. 
1500-2700 m., July 1908 (No. 3041)- Western Hupeh: Fang 
Hsien, alt. 2100 m., November 1907 (No. 581). 

Allied to P. subcanus from which it chiefly differs in the unusually large leaves of 
the flowering branchlets. No. 581, though difiering from the type in the subglabrous 
leaves and the glabroiis apex of the fruit, probably belongs to this species. 

Philadelphus incanus Koehne in Gartenfl, XLV. 562 (excludenda 
planta Henry No. 8823 quae ad P. subcanum pertinet) (1896). 
Schneider, III. Handb. Laubholzk. I. 370 (1905). 

Western Hupeh: Hsing-shan Hsien, thickets, alt. 1200-1800 m,, 
June and October 1907 (No. 574), April 1907 (No, 3048), May 1907 
(No. 3054), July 1907 (No. 3053); north of Ichang, thickets, alt. 1200- 
2100 m., July and November 1907 (No. 583) ; north and south of Ichang, 
thickets, alt. 1200-1800 m., June 1907 (No. 3049); Fang Hsien, thick-

Patung Hsien, thickets, alt. 1200 m., July 1907 (No. 3053)- 

Besides in other characters it differs from P. mbcanus in the longer and more 
ri^d hairs which cover the ovary and the sepals.

Most nearly related to D. scahra Thunberg, which is easily distinguished by the 
leaves being only sparingly stellate-pubescent and therefore green on the under- 
side, without simple hairs on the veins, by their crenulate-serrate margin with ap- 
pressed serratures and by the narrow, nearly cyhndric panicles, while the related 
D, hypoleuca Maximowicz differs in its five styles and narrow panicles. I take 
pleasure in associating with this species the name of Mr. C. K. Schneider whose 
"Beitrag zur Kenntnis der Gattung Deutzia" (in Mitt. Deutsch. DendrMes. XIII. 
172-188 (1904) is a valuable contribution to the knowledge of this genus.

In its spreading pilose ferrugineous pubescence and its long peduncled few- 
flowered inflorescence this is very unUke any other species. No. 4884 differs 
from the type somewhat in the heteromorphous pubescence of the calyx and in the 
less marked development of the central ray of the hairs on the upper side of the 
leaves.

Western Szech'uan: Chin-ting-shan, thickets, alt. 1200-1500 m.,

Differs from the type chiefly in its elongated filaments much exceeding the 
anthers as well in the interior as in the exterior stamens, in the smaller cymes and 
in the green only sparingly stellate-pubescent under side of the leaves. This may 
be a distinct species, if the characters should prove to be constant, but as the ma- 
terial at hand is meagre and does not seem of quite normal development, it may be 
referred provisionally to D. setchuenensis as a variety.

Differs from the type chiefly in the denser more or less heteromorphous pu- 
bescence of the leaves and the many-flowered inflorescence with the pedicels as 
long or shorter than the calyx. Deutzia corymbiflora erecta Lemoine differs slightly 
m its more ascending branchlets, smaller inflorescence and narrower leaves with 
sometimes nearly homomorphous pubescence. The Deutzia figured by Burvenich 
(m Rev, Hart. Belg. XXVII. 157, t.) as D. corymbiflora does not belong here, but is 
apparently D. purpurascens (Franchet) Eehder or one of its hybrids.

Wilson's specimens show a wide range of variation. His No. 2891, with its small 
and dense inflorescences on short branchlets bearing only a few small leaves and 
sometimes nearly leafless, seems nearest to the type. All his specimens, however, 
tT^^^u^ flowers larger than those described by Franchet, particularly No. 2901, 
which has the petals 14 mm. long and 10 mm. broad. Sometimes, as in No. 2899, 
the flowers are borne on elongated branchlets with three pairs of well developed 
leaves. This tends to show that the type specimen does not present the normal 
development of the species, but a somewhat abnormal precocious state, as may be 
inferred from the fact that the type specimen was collected in April, while Wilson's 
flowenng specimens were all gathered in June. No. 1188 has the pubescence of 
the calyx heteromorphous, as described by Franchet, while in the other specimens 
the pubescence is homomorphous except in Delavay's specimen from Yunnan, 
which differs besides in its broader leaves.

m., June 20, 1908 (No. 2900). 

Wilson's No. 2993, from which the description given above is drawn, is in its 
characters clearly intermediate between jD. glomeruliflora Franchet and D. longi- 
folia Franchet, and I have no doubt that it is a hybrid between these two species, 
both of which have been collected in the neighborhood of Tachien-lu. The other two 
numbers seem closer to Z). longijolia and may possibly represent a white-flowered 
variety of that species, though they differ in the pubescence. The intermediate 
character of the hybrid is most clearly shown in the hairs of the under side of the 
leaves, which have 4-^ rays in D. glomeruliflora and 12-14 in D. longijolia, while in 
No. 2993 they have 5-8 rays and in the other two numbers 8-10 rays. The flowers 
are white in the first species, purplish outside in the second species, and slightly 
purplish in No. 2993, while in the two other numbers they are white aa in 
D. glomeruliflora. In habit the hybrid resembles most the last named species. 

The species of Deutzia are known to hybridize easily in cultivation, and they 
seem to do the same in a wild state if they have the opportunity, for besides the 
hybrid described here, another hybrid, between D. discolor and D. mollis, described 
below, has been collected in a wild state.

From all the allied species this is easily distinguished by the nearly sessile leaves

Though Wilson's specimens differ from the description of D. longifolia Franchet, 
of which I have not seen the type, in the broader leaves and larger flowers, I have 
no doubt that they must be referred to this species. The leaves of Wilson^s speci- 
mens are sometimes ovate-oblong and 3 cm. broad and the petals attain 14 mm. 
in length. From the allied species D. longifolia is readily distinguished by the 
narrower, rather thickish leaves, rugose above and with strongly elevated veins 
on the whitish under side, by the heteromorphous pubescence of the under side, 
the purplish flowers in many-flowered paniculiform cymes usually loose and borne 
on elongated branchlets, but sometimes rather dense and on short branchlets, by 
the usually four styles and larger capsules measuring about 6 mm. in diameter.

(Veitch Exped. No. 1919). 

Related to D. corymhosa R. Brown and D. partdflora Bunge, from both of which 
it is easily distinguished by the hairs on the under side of the leaves having only 
5-6 rays, by the filaments extending undivided above the insertion of the anthers, 
and by the color of the flowers. The flowers vary greatly in size; in the type the 
petals are 10 mm. long, while in No. 2897 they are scarcely 6 mm. long and sUghtly 
longer m No. 3566; in No. 1919 they are 7 mm. long. No. 3586 differs besides in 
its smaller leaves nearly glabrous beneath. 



SYNOPSIS OF THE CHINESE DEUTZIAS. 

While determining the Deutzias of the Wilson collection I have found a large 
amount of undetermmed material which led me to a closer study of all the Chinese 
species. The results of this study are embodied in the following key and enumera- 
tion of the Chinese species.

Allied to D. hypoleuca Maximowicz which differs chiefly m its densely serrulate 
thinner leaves, the slenderer petioles, 2-5 mm. long and the 4-5 styles. 

4. Deutzia pulchra Vidal, Revis. PL Vase. Filip. 124 (1886). 
Formosa: Bankinsing, A. Henry (Nos. 38, 477). 

The occurrence of tMs Philippine species in Formosa is phytogeographically in- 
teresting. Henry's specimens agree exactly with Elmer's No. 8414 from the prov- 
ince of Benguet, except that in the latter the stellate hairs on the upper surface of 
the leaves have usually 4-6 rays interspersed with comparatively few hairs with 
10-12 rays, while in the Formosa plant most of the hairs have 6-8 rays and many 
10-14 rays. The inflorescence is not corymbifonn as might be inferred from 
Vidal's description, but a panicle 6-11 cm. long and 5-8 cm. broad.

Closely related to D. Sieholdiana Maximowicz, which is easily distinguished by 
its generally ovate leaves, more coarsely serrulate with spreading teeth, by the 
calyx-teeth being about half as long as the tube which is broader than long, and by 
its smaller flowers with more spreading petals.

I have not seen the type specimen itself, but a good photograph of it. As this 
and Franchet's description agrees fairly well with the specimens cited above, I 
trust that I have made no mistake in referring them to D. setchuenensis,

I have seen no specimen of this species; according to the description by Fam- 
panini it is nearest to D. setchuenensis var. corymhifloray but differs chiefly in the 
longer calyx-lobes and narrower rose-colored petals.

Calyx-teeth lanceolate or sometimes oblong-ovate, as long or longer, rarely 
slightly shorter, than the tube; the cymes usually rather dense and many-flowered, 
more or less panicle-like. Besides the following species D. staminea R. Brown and 
probably D. macrantha Hooker f. and Thomson, which I have not seen, belong to 
this group.

Deutzia purpurascens differs in several important characters from D. discolor, 
and I consider it a well marked species much less closely related to D. discolor 
than any of the following species of this group. It is particularly well distinguished 
by the stellate hairs of the under side of the leaves which have only 5-7 rays, while 
in all the following species they have 10-14 rays, and besides from D. discolor by 
its smaller generally ovate leaves, greenish beneath, smaller inflorescence, purplish 
flowers, and shorter stamens with the filaments exceeding the anthers.

Differs from the type chiefly in its few-flowered inflorescence, white petals, and 

in the apex of the filaments or of the teeth of the filaments being obtuse. Possibly 

a distinct species.

This and the following three species are closely related to D. discolor Hemsley, 
and I am not yet quite convinced that they are really specifically distinct; the 
characters on which they are based seem to be rather slight and inconstant, but 
as the material I have seen of each of these species is rather scant, I do not feel 
justified to make a change, until more and completer material is available.

Western Hupeh: June 1901, E, H. Wilson (Veitch Exped. No. 1917) (Herb. 
Arnold Arboretum.). 

Wilson's No. 1917 is quoted by the author of D. mollis as belonging to that 
species and it looks mdeed at the first glance only hke a slight variation, but a closer 
exammation reveals certain features which indicate at once its hybrid origin, 
particularly the irregular aestivation and the sterile antbere. All the other char- 
acters in which the plant m question differs from D. moUis point toward D discolor 
as the other parent; the stellate hairs of the under side of the leaves have 12-14 



SAXIFRAGACEAE. — DEUTZIA 21 

rays in D. discolor and generally 4 rays with a central ray in D. mollis^ while in 
the hybrid they have generally 8 rays only part of them with a central ray; the 
calyx-lobes, which are lanceolate and longer than the tube in D. discolor and 
broadly ovate, abruptly acuminate and about half as long as the tube in D. molliSf 
are oblong-ovate, acuminulate and about as long as the tube in the hybrid; the 
filaments, which are gradually narrowed toward the apex in D. mollis and distinctly 
toothed in D. discolorj are in the hybrid mostly abruptly contracted or have only 
very short teeth ; also the shape of the leaves and some other minor characters are 
intermediate.

I have not seen the type specimen, but according to the description the species 
differs from D. discolor in so many points that I cannot follow Schneider in referring 
it to that species as a variety.

Exped. No. 1870); Ou-tan-shan, C. Silvestri (ex Pampanini). 

The Hupeh specimens differ from the type in their narrower leaves and in the 
elongated and somewhat wavy rays of the hairs of the imder side of the leaves, so 
that the tomentum appears more villose and not as closely appressed as in the 
type; in this respect it approaches the following variety. I have seen no specimen 
of Pampanini's var. insignis, but from his description it appears not to be differ- 
ent from typical D. grandiflora.

Differs from the type chiefly in the heteromorphous and thinner grapsh green 
pubescence of the under side of the narrower leaves which are usually broadly 
cuneate at the base; the stellate hairs have only 5-7 rays mostly with a central 
ray, not 7-9 without central ray as in the type. The flowers of No. 4522 agree 
with those of the type. I cannot follow Schneider in referring the Shensi plant to 
D. grandiflora, var. glabrata Maximowicz; the pubescence of the latter ia homomor- 
phous, the hairs havmg 6-9 short rays and are only sparingly distributed over the 
lower surface, not touching each other.

Korea: Ping Yang, September 18, 1905, J. G. Jack (Herb. Arnold Arboretum). 

Closely related to D. grandiflora Bunge, and particularly to its glabescent variety 
7 glabrata which, however, differs in the shorter petioles, the shorter scarcely acum- 
inate teeth of the leaves, and their less prominent venation, in the hairs of the upper 
surface having usually 5-6 rays and those of the lower surface 6-8 rays and also in 
the shorter peduncles and pedicels. Deutzia hamata Koehne, which is similar in 
foliage, differs in the pecuhar development of the pubescent calyx. 

25. Deutzia hamata Koehne in BoL Jahrb. XXXIV. No. LXXV. 37 (1905). 
Shantung: Laushan Mts., Zimmermann (Nos. 335, 348 ex Koehne). 

This species is well marked by the peculiar development of the calyx which has 
the margin incurved forming a hollow ring open toward the apex of the ovary and 
partly covenng it ; the spreading lanceolate calyx-lobes are borne on the outside of 
the nng. 

Subsect. 5. COREANAE Rehder, n. subsect. 

Distinguished from all the other Deutzias by the solitary or rarely two flowers 
appeanng from leafless buds and borne on short stalks hidden by the bud-scales; 
calyx-tube ovoid, truncate at the apex with short triangular lobes; styles slender, 
3; leaves on both sides sparingly covered with hairs with 4-5 rays.

Franchet^s variety ^ mongolica does not seem sufficiently distinct to be separated 
as a variety; of the specimens named above only Purdom's No. 40 with simple 
hairs along the midrib beneath would belong to this variety; all the others must 
be referred to his var. a Bungei, though I never saw a specimen with perfectly 
glabrous leaves; they all have at least a few hairs, sometimes nearly imperceptible, 
on the lower surface. 

Deutzia parviflora, var. musaei Lemoine in Jour, Hort. Sac. France, s^r. 4,

inflorescence with fewer creamy white flowers.

Closely related to D. parviflora Bunge, from which it differs in the much smaller 
flowers, m the shape of the inflorescence, and in the stellate hairs of the under 
side of the leaves being more numerous and having generally 8-10 rays. The 
inflorescence much resembles in its mode of branching that of D. mollis Duthie, 
the partial mflorescence being rather dense and borne on elongated and remote 
branchleta.

This 13 as far as I know the first time that H, paniculata has been found in China. 
The specimen differs very Uttle from the Japanese plant; the serratures of the

This is apparently a very variable species and closely related to H. Bret Schneider i 
from which It can be separated only by the glabrous or glabrescent under side of 
the leaves more or ess cuneate at the base. In the type the under side of the leaves 
IS glabrous or nearly glabrous except the strigose veins which are yellowish on the 
upper side; the branchlets are bright reddish brown with the bark without lenticels 
and soon separatmg mto thm flakes. Wilson's Nos. 4391 and 4899 seem nearest 
to the type. No 4484 is also near the type, except that it has the leaves loosely 
pubescent beneath, while the other numbers of Wilson differ in their large foliage,

Western Szech'uan: Wa-shan, thickets, alt. 1500-2250 m., 
July 1908 (No. 2411). 

Closely related to H. xanthoncura Dials which is easily distinguished by the leaves 
being serrulate, narrower and larger and on the under side nearly glabrous except 
the strigose veins.

The Szech'uan and the Hupeh plants differ slightly; the former has the leaves 
generally ovate-oblong and approaches also in the somewhat darker color of the 
branchlets the type, while the leaves of the Hupeh plant are elliptic-oblong or 
oblong-obovate.

Adistinct species with large and handsome foliage similar to H. robusta Hooker 
f. & Thomson, which is easily distinguished by its strigose pubescence, ovate

Closely related to H. longipes Francbet which is chiefly distinguished by broader 
Btrigose or glabrescent leaves, strigose branchlets, longer petioles and white flowers. 
From all allied species H. glabripes differs in the leaves having a densely villotis 
under side and at the same time a glabrous petiole and a glabrous or nearly gla- 
brous midrib.

This form is probably best treated as a variety of H. aspera, though it shows a 
close relation to ff . villosa; it lacks, however the villous and fulvous hairs of that 
species. In No. 2404 and 44S2 the pubescence is less velutinous and approaches 
that of H. strigosa.

but is easily distinguished by the nearly velutinous pubescence of the under side 
of the leaves and by the shorter petioles.

Closely related to H. aspera D. Don which chiefly differs in the fimbriate-denticu- 
late leaves being on the under side on the veins and veinlets covered with a villose- 
hirtellous, not appressed strigose pubescence and in the larger capsules with 
usually three styles. The difference in pubescence and serration, serrulate, with the 
teeth pointing forward in H. strigosa, and denticulate or dentate with spreading 
teeth in H. aspera, seems to distinguish clearly the Chinese from the Himalayan 
plant of which I have seen Wallich's No. 440 B; the pubescence of that specimen 
agrees well with Don's original description "foHis . . . subtus dense cano-tomen- 
tosis " and Clarke's description "under surface with gray woolly hairs," terms 
which hardly could be applied to the strigose pubescence of the Chinese plant. In 
size and shape of foliage the Chinese plant seems exceedingly variable, and the fol- 
lowing forms pass gradually into each other.

The leaves of this form are sometunes 28 cm. in length and 11 cm. in width and are 
generally ovate-lanceolate or sometimes ovate-oblong and nearly rounded at the 
base. This form passes gradually into the type, and some specimens enumerated 
under the type, as Wilson's Nos. 2394 and also No. 773 and Henry's No. 1083, 
with leaves 22 cm. long and 6.5 cm. broad, might perhaps be referred to var. 
macrophylla, but the leaves are comparatively narrow and cuneate at the base.

perhaps better here.

The close relationship of this species with H. robusta Hooker f. & Thomson is 
still more evident in Wilson's specimens than in the type specimen; the leaves of 
Wilson's specimens are larger, the largest measuring 25 cm. in length and 17 cm. in 
width, the longest petiole is 20 cm. long and in some specimens the sterile flowers 
have strongly toothed sepals. It is also closely related to H. longipes Franchet, 
which is chiefly distinguished by its smaller and thinner, coarsely serrate leaves, 
lees densely strigose or glabrescent beneath.

34 WILSON EXPEDITION TO CHINA 

Hydrangea longipes is closely related to H. Giraldii Diels and also to H. rohusta 
Hooker f . & Thomson as Franchet has already stated, and some of the specimens, 
as Wilson's No. 580, which has rather densely pubescent and large leaves, seem 
somewhat intermediate. Hydrangea longipes Franchet and H. longipes Hemsley are 
identical; the apparent discrepancies in the descriptions do not exist in reality. 
First it is to be stated that H, longipes Hemsley does not belong in the section 
Calypiranthe where Hemsley placed it, apparently misled by the fact that the 
petals occasionally cohere at the apex, but this may happen in almost all species 
of the subsection isperae, which does not differ in the structure of its flowers from 
Calypiranthe. The description of Franchet contains some misleading inaccuracies; 
the flowers have 10 stamens and 2 styles, not 5 stamens and 3 styles as Franchet 
describes them, and the leaves of at least part of the specimens collected by David 
attain a length of four inches, while Franchet says " folia vix ultra-poUicaria." 
The only difference I can find between Franchet's and Hemsley^s specimens is the 
somewhat slighter pubescence of the latter, the leaves being sometimes nearly 
glabrous. A form based on No. 846 of C. Silvestri from the mountains of Chia- 
yuen-kou, western Hupeh, with the radiant flowers smaller and greenish has been 
described by Pampanini as H, Hemsleyanaj var. Pavoliniana {Nuov. Giom. Bot. 
Hal n. ser. XVII. 284 [1910]).

SYNOPSIS OF THE CHINESE SPECIES OF HYDRANGEA. 

As the determination of the copious material collected by Wilson of this genus 
has necessitated a study of all the Hydrangeas of China and the adjacent parts of 
Asia, it may be useful to place the results of this study permanently on record in 
the shape of a synopsis of all the Chinese species of Hydrangea.

Subsect. 1. PETALANTHAE Maximowicz, I. c. 

This subsection is taken here in a wider sense than in its original conception 
and includes all the species with a wingless or nearly wingless seed. The ovary 
is partly superior with 3-4 styles and the cymes are usually flat; the petals 
are spreading or reflexed and usually persistent during anthesis. Petioles 1-3, rarely 
5 cm. long.

No. 7385 of Henry and No. 602 of Rosthorn represent the form ^^hjiU tne 
flowers sterile, like the well-known garden forms. As long as the form with fertile 
flowers has not been collected in a wild state in western China, its spontaneous 
occurrence must remain doubtful. So far no European collector has ever seen and 
coUected it wild in these regions and the notes of the native coUector who gathered 
the plants for A. von Rosthorn must be taken with some caution.

Piptopetalae Maximowicz in Mem. Acad. Sci. St. Petershourg, sdr. 7, X. No. 
XVI. 8 (in part) (1867). , 

This subsection is chiefly characterized by the partly superior ovary with 3-4 
styles and by the seeds with a wing on each end. The inflorescence is strongly 
convex with remote ramifications and sometimes paniculiform; the fertile flowers 
are white in the Chinese species and the petals drop before the opening of the 
anthers. The petioles do not exceed 5 cm. in length.

I do not see any reason to doubt the identity of Bretschneider's plant with 
H. vestita f var. puhescens Maximowicz; the description of the latter agrees exac y 
with the form cultivated in the Arnold Arboretum which shows a much ^^^^ 
pubescence than Koehne's No. 4070. The true H. heteromalla Don (H. resw^ 
Wallich) is easily distinguished by the dense white tomentum of the under side 
the leaves and their fimbriately denticulate margin.

Hydrangea Bretschneideri, var. Giraldii Rehder, n. var. 

Hydrangea Giraldii Diels in Bot. Jahrh, XXIX. 373 (1900). 

I am not able to separate H, Giraldii specifically from H. Bretschneideri; it seems 
to differ only in narrower leaves gradually narrowed into the petiole and in the paler 
color of the bark. In the shape of the leaves it resembles H. xanthoneura, var. 
Wilsonii Rehd. which is easily distinguished by the leaves being glabrous or nearly 
so beneath.

This subsection is chiefly characterized by the inferior ovary developing into a 
hemispheric or turbinate capsule truncate at the apex. The seeds have a wing 
on each end; the styles are usually 2; the petals fall off before the stamens are fully 
developed, sometimes as a whole by cohering at the apex. The petioles sometimes 
attam 20 cm. in length.

Differs from the type by its less villous tomentum. Branchlets usually only 
appressed strigose with fulvous hairs at the nodes; petioles hirsute with fulvous

This is the only Chinese specimen I have seen which I can refer to the typical

and partly 3 styles. The variety described by Pampanini as H, aspera, var. cordata 
(in Nuov. Giorn. Bol Hal n. ser. XVII. 283, [1910]), based on Nos. 835, 835" of 
C. Silvestri from Ou-tan-shan, western Hupeh, probably does not belong to H. aspera 
nor to H. strigosay but as I have seen no specimens and the description given is too 
brief, I am not able to place it.

This section is well characterized by the compressed seeds having a narrow wing 
all around, by the climbing habit, the branchlets affixing themselves by means of 
rootlets, by the brown partly evanescent pith of the one year old branchlets and by 
the petals being thrown off as a whole by the extending stamens. The falling off 
as a whole of the petals occurs also occasionally in the section Asperae^ which 
hardly differs from Calyptranthe in the structure of the flowers and also contains a 
few climbing species.

The following three Chinese species from Kwei-chau recently described by Ld-

too incomplete for recognition.

The first resembles in its short stamens //. Lobbii Maximowicz, but differs in its 
tomentose pubescence, the second is closely related apparently to H. heteromalla 
Don, but has lanceolate petals, while the third may belong either to the PetO' 
lanthae or to the Heteromallae, the description of the seeds as "imperfecte ob- 
longa" may mean that they are winged or wingless.

from any of the following four varieties. No. 4339 has the petioles and the leaves 
slightly pubescent beneath, and may be considered a transition to the following 
variety.

1908 (No. 1251, in part, flowering specimen only); Mupin, cliffs, alt. 
1800 m., July 1908 (No. 1251, in part, flowering specimen). 

Strikingly different from the type in the dense and soft tomentum of the under 
side of the leaves, which otherwise in texture, size and shape resemble closely those 
of the t3T)ical form. 

Schizophragma integrifolium, var. denticulatum Rehder, n. var.

Differs from the type in its thinner, dentate or denticulate leaves, slightly pu- 
bescent on the veins beneath or sometimes glabrous. In the No. 2563 which I 
consider the type of this variety and also in No. 4462 the leaves are sinuately 
dentate, while in all the others they are merely denticulate.

SAXIFRAGACEAE. — DICHROA 43 

Western Szech'uan: Wa-shan, cliffs, alt. 1200-1800 m., July 
1908 (No. 2569). 

Differs from the type in its thinner and smaller leaves glaucescent beneath, 
sometimes nearly oblong in outline and in its smaller sterile flowers. 

To complete the enumeration of the Chinese Schizophragmas, the following 
varieties and species which are not represented in the recent Wilson collection 
are appended here. 

Schizophragma integrifolium, var. minus Rehder, n. var. 

A typo recedit foliis membranaceis, ovatis, v. subcordatis, integris v. fere integris, 
minoribus, tantum 8-10 cm. longis et 5.5-6.5 cm. latis, supra flavo-viridibus, subtus 
pallidioribus, sepalis florum sterilium oblongo-ovatis, acutiusculis, basi cuneatis, 
3-3.5 cm. longis et 1-1.5 latis. 

Hupeh: A. Henry (No. 5965, type); South Washan, wet place, June 1900, 
E. H, Wilson (Veitch Exped. No. 1065). 

Differs from the type in its smaller and thinner leaves and much smaller sterile 
flowers. 

Schizophragma hypoglaucum Rehder, n. sp. 

Frutex radicibus scandens. Folia chartacea, oblongo-ovata, manifesto acumin- 
ata, basi rotundata v. late cuneata, integenima, 8-15 cm. longa et 3.5-6.5 lata, 
supra obscure viridia glabra, subtus glauca (sub microscopio dense papillosa), 
glabra axillis barbatis exceptis. Cyma fere glabra; tubus calycis glaber; sepala 
florum sterilium oblonga vel anguste oblonga, basi cuneata, apice obtusa, subtus 
glaucescentia et papillosa, 3-5 cm. longa et 7-17 mm. lata. 

Szech'uan : Mt. Omei, July 1904, E, H. Wilson (Veitch Exped. No. 4885). 

In the shape and smoothness of the leaves it resembles much S. integrifolium, var. 
glaucescens Rehder which has the leaves glaucescent beneath, but the species is 
easily distinguished by the intensely glaucous color of the imder side of the leaves 
and particularly by the papillae which are entirely wanting in that variety, also 
by the dark green upper side, the glabrous calyx-tube and the obtuse sepals of the 
sterile flowers. It is so strikingly different from typical S. iniegrijolium that it is 
hardly advisable, though the variety glaucescens seems to represent a connecting 
link, to consider it a variety of that species, particularly as the papillosity of the 
under side of the leaves affords a good morphological character for separation.

Korea: Quelpaert, T. Taquet (Nos. 807,808,2885). 

So far as I know S. hydrangeoides has never been reported from Korea before. 
Taquet's No. 807 and 808 represent the type of Hydrangea Taquetii L6veilld.

SORBARIA A. Br. 

Determined by Alfred Rehder. 

Sorbaria arborea Schneider, III. Handb. Laubholzk. I. 490, fig. 297 
(1905). 

Western Hupeh: Chang-lo Hsien, thickets, alt. 1500-2100 m., 
July and October 1907 (No. 499^); Chang-yang Hsien, thickets, alt. 
1500-1800 m., July 1907 (No. 2741); Fang Hsien, thickets, alt. 1500- 
2100 m., July 1907 (No. 2742); Hsing-shan Hsien, woodlands, alt. 
1500-1800 m., July 1907 (No. 2743); Patung Hsien, thickets, alt. 
1500-2400 m., July 1907 (No. 2743^). Western Szech'uan: Mupin, 
woodlands, alt. 1500-2400 m., November 1908 (No. 1235, in part); 
Wa-shan, thickets, alt. 1600-2200 m., July 1908 (No. 2745). 

This variable species is most nearly related to S, lAndleyana Maximowicz from 
which it differs in its longer stamens, two or three times as long as the petals, in 
the shorter calyx-tube and in the leaflets being cuneate at the base and covered 
beneath with a fasciculate floccose tomentum or glabrous in one variety. 

Sorbaria arborea, var. subtomentosa Rehder, n. var. 

■A- typo recedit foliis subtus tomento fasciculato densiore usque ad 
maturitatem persistente vestitis, argute minuteque biserrulatis, 
venis magis congestis circa 2 mm. tantum distantibus, inflorescentia 
dense floccosa, densiore, ramis adscendentibus, floribus majoribus, 
petahs 3 mm. longis, carpellis pubescentibus vel glabris. 

Western Szech'uan: Wa-ssu country, Wen-chuan Hsien, wood- 
lands, alt. 1800-3100 m., November 1908 (No. 1235, fruiting specimen, 
type); Ta Hsing-ling, Ching-chi Hsien, thickets, alt. 1600-2200 m., 
August 1908 (No. 2744, flowers); Pan-lan-shan, west of Kuan Hsien, 
woodlands, alt. 2100-2400 m., September 1910 (No. 4474)- 

Differs from the type in its denser persistent tomentum of the under side of 
the leaves, their more closely set veins, 2 mm. apart, while in the type they are 3-4 
mm. apart, and in the more densely tomentose inflorescence. In the type speci- 
men the follicles are sparingly pubescent, while in the flowering specimen they are 
quite glabrous; therefore these two specimens may possibly represent two dis- 
tmct formsj but in foliage they are exactly alike.

August 1910 (No. 4477); Mupin, woodlands, alt. 2400-2700 m., 
October 1910 (No. 4340), 

Differs from the type chiefly in its glabrous foUage. The Hupeh plant, which 
I consider as representing the type of this variety, has the leaves generally oblong- 
lanceolate to lanceolate, the inflorescence narrower with ascending branches and 
the stamens sometimes nearly three times as long as the petals, while the Szech'uan 
form has the leaflets generally oblong-ovate or oval-ovate, the inflorescence loose 
with spreading branches and the stamens less than twice as long as the petals. 
No. 4340 differs again in the more closely set veins of the leaflets, resembling in 
this respect the var. subtomentosa.

I formerly was unable to find clear distinctions in the descriptions of R. Svnnhoei 
Hance and R. hupehensis; therefore I combined the two species. Now I think, 
however, that there are constant characters by which the two plants can be dis- 
tinguished. R. Svnnhoei is evergreen, whereas R. hupehensis seems to have de- 
ciduous leaves.

Of the genus Maddenia Hooker f. & Thomson (in Hooker Jour, BoL and Kew 
Gard. Misc. VI. 381 [1854]), only two species, both from the Himalayas, are enum- 
erated in the Index Kewensis and its supplements. Wilson found in China three 
new species which have the deciduous and closely serrate leaves of Maddenia, 
while the closely related Pygeum has persistent entire leaves. These important 
distinguishing characters are not mentioned by Focke (in Engler and Prantl, Nat. 
Pflanzenfam. III. 1, 51), who also states there that the pistillate flowers have two 
carpels developing into two drupes. According to Hooker f. & Thomson, how- 
ever, their structure is quite different. The flowers with two pistils are staminate, 
and their pistils do not bear styles, but a sessile stigma, and contain only abortive 
ovules. The twin-fruits which these flowers produce attain only half the size of the 
normal fruits and form no seeds. The normal fruits originate from perfect flowers 
with a pistil bearing a long style and contain one seed, as only one of the two ovules 
develops. In the Chinese species I have never found two pistils in one flower. 
Flowers without exserted styles can be found only in very small numbers, and as 
far as I have examined these flowers, they contain only one pistil with a minute 
style and a rudimentary stigma. The presence of two pistils must therefore be 
considered as of less importance than the character of the foliage. 

A key to all the species is appended here:

From this species Prunus phaeosticta Maximowicz differs in the leaves being 
copiously and minutely punctulate beneath and fronoi P. sjrinulosa Siebold & Zuc- 
carini in its narrower leaves broadest above or at the middle with nearly spinu- 
lose teeth curved forward, in the branchlets and racemes slightly pilose and in 
the stamens exceeding 20 in ntunber; P. macrophylla Siebold & Zuccarini, P, 
acuminata Roemer and P. Jenkinsii Hooker f. differ in other characters as well as 
in the shape of their much larger leaves. 

Primus Wilsonii (Diels ms.) Koehne, n. comb.

tiferis qui ad P. sericeam Koehne pertinent) (1906). 

^ 

The type as described by C. K. Schneider differs in the axis of the racemes, 
the pedicels, the cupula and the sepals inside and outside being short-hirtellous 
and becoming glabrous. Besides, the petioles are described as without glands, the 
leaves as rather remotely serrulate, whitish beneath and the stamens as nearly 
t^vice as long as the petals. I have, however, after a comparison with Schneider's 
specimen, no doubt that the follo^-ing variety belongs here. 

Prunus Wilsonii, var. leiobotrys Koehne, n. var. 

Arbor 10-metralis trunco 0.45 m. diam. Racemorum axis pedicelli- 
que glabri; cupula extus glabra, sed sepala ut in typo utrinque hirtella

basi insidentes; lamina densiuscule serrulata, subtus subcana. Stamina 
petalis dimidio longiora (stamina 6 mm., petala 4 mm.). Ceterum

To this variety seems to belong: Padus napaulensis (Ser.) C. K. Schneider 
forma? in Fedde, Rep. Nov, Sp. I. 68 (1905), collected in Yunnan by A. Henry 
(No. 10547). This form differs from P. Wilsonii, var. leiobotrys only in the fewer 
and shorter hairs on the under side of the leaves, and might be considered as m- 
termediate between P. napaulensis and P. Wilsonii (not between P. napaulensis 
and P. sencea as Schneider suggests), but in numerous specimens of P. napaulensis 
the leaves are always glabrous beneath.

the serration of the leaves, are otherwise very different and can always be easily 
distinguished with certainty. It is less easy to distinguish P. ssiori from P. brachy-

This species is closely related to /. Fargesii Franchet, which differs in the shape 
of the leaves. These are entire or mostly entire below the middle, with longer 
bases gradually narrowed into the petioles, and at the apex are narrowed into a 
shorter and broader point. It forms a transition between the sections Micro' 
dontae and Repandae^ and might perhaps be better placed in the latter, although 
I have placed it with the Lemurenses on account of its close relationship with 
/. Fargesii.

Acer fvlvescens seems most nearly related to Acer pictum Thimberg, which has 
the branches covered with the same kind of bark, but differs in the glabrous gen- 
erally five-lobed leaves and the shorter wings of the fruits. Acer hngipes, which is 
very similar, is easily distinguished by the smooth greenish or purplish bark of the 
younger branches without lenticels, the perfectly glabrous corymbs and petioles 
and by the larger leaves, their pubescence being not yellowish or fulvous. -Nos. 1162 
and 1907 differ from the type in their puberulous inflorescence. No. 1907 has even 
the whole petioles and the young branchlets below the nodes puberidous.

ACERACEAE. — ACER 85 

Though Gleditsch's species is based only on a single leaf without flowers or 
fruits, the figure leaves no doubt that it is the same as A. laetum C. A. Meyer, and 
his name being about 45 years older must supersede that given by Meyer. Acer 
cappadocicum is based on a leaf collected by Gundelsheimer, who traveled with 
Toumefort in Asia Minor during the years 1700 to 1702. The same species is 
mentioned by Toumefort {Coroll. 43) under the name Acer orientalis Hederae foliOf 
but without any description or remark.

To this variety I refer all Chinese specimens I have seen from Hupeh, Szech'uan, 
and Yunnan. It differs from var. indicum in its smaller leaves with narrower and 
longer lobes, purplish when imfolding and less densely bearded in the axils of the 
primary veins beneath and in the smaller flowers and fruits. In the shape and size 
of its leaves it much resembles A. pictum, var. parviflorum C. K. Schneider, but is 
easily distinguished by the smooth greenish bark of the yoimg branches. No. 1903 
from Szech'uan differs from the typical form in its somewhat larger leaves, 7 to 
11 cm. long, and Henry's No. 10877 from Yunnan in its sUghtly hairy calyx and 
cilia te sepals. 

Acer cappadocicum and particularly its variety sinicum is often confounded with 
Acer pictumj as the relative length of wing and nutlet, usually given as the chief 
distinguishing character, is very variable in both species. The best character by 
which to distinguish these two species seems to lie in the bark of the younger 
branches; this character has moreover the advantage that it is always recognizable 
even in winter. In Acer pictum the epidermis of the young branches ceases growing 
during the first summer, and the bark of the branches becomes corky and grayish 
white, ashy gray or Ught grayish brown and is marked with conspicuous lenticels and 
in the second year with slight longitudinal fissures, while in A. cappadocicum the 
branches remain covered by the growing epidermis for several years, and are there- 
fore smooth, ranging from green or greenish to purple in color, marked with only 
few and small lenticels or are without lenticels. Other distinguishing characters 
are the generally truncate leaves, at least in the Chinese variety, in A, pictum they 
are subcordate, the more convex and smaller nutlets in A. cappadocicum and the 
wing contracted at the base, while in A. pictum the nutlets are much compressed, 
almost flat, and the wings are of nearly the same width through their whole length. 
The terminal winter-buds of A. pictum have 2 to 3 pairs of outer scales, those of 
A. cappadocicum 3 to 4 pairs.

above, the following new combinations of varietal names:

Acer laetum, var. cultratum Pax in Engler, Pflanzenreich, Heft. 8 (IV. 163), 48 
(1902). 

Of the other published names two, Acer laetum, var. colchicum Pax and Acer 
laetum, f. viride Hesse represent the type and need therefore no new names, while 
the two following varieties must be referred to other species. 

Acer laetum, var. tomentosulum Rehder is identical with Acer longipes Franchet. 
It was originally based on a flowering branch with undeveloped, only partly im- 
folded leaves, apparently quite different from those of A. longipes, of which I also 
had seen at that time only a few specimens. Additional material, however, recently 
received convinced me that it cannot be separated from A. longipes. 

Acer laetum, var. Regelii Pax is identical with A. turkestanicum Pax in Engler, 
Pflanzenreich, Heft 8 (IV. 163), 48 (1902), as is shown by the collection of Turkes- 
tanian Maples of the St. Petersburg Herbarium, wMch was loaned to me through 
the kindness of Mr. Lipsky. The leaves are always pubescent beneath, though at 
maturity the pubescence is sometimes much reduced and hardly noticeable with- 
out a lens, which probably accounts for the fact that Pax placed the fruiting speci- 
men imder the glabrous A. laetum.

Acer amplum is nearly related to A. cappadocicum Gleditsch, which differs chiefly 
in its smaller long-peduncled inflorescence and smaller leaves with narrower and 
longer lobes. It forms with A. catalpifolium and A. longipes a group of closely 
related species characterized by the sessile ample inflorescence.

^ This variety differs from the type chiefly in its smaller more often 3-lobed leaves 
with longer and narrower lobes and in the smaller fruits with narrower wings. The 
specimens from Kuling approach the type in the larger mostly 5-Iobed leaves and 
the somewhat larger fruits.

Acer catalpifolium is nearly allied to A. amplum and to A. longipeSj both of wMch 
are easily distinguished by their three- or five-lobed leaves. Acer longipeSy which 
occasionally produces some undivided leaves, differs besides in the pubescent under 
side of the leaves. According to Wilson this species is a handsome tree of very dis- 
tinct appearance with the foliage turning yellow in autumn,

part; Hsing-shan Hsien, woods, not common, alt. 1800 m., May 10,

Additional material has shown that the leaves are sometimes five-lobed, and 
that apparently my A, laetum, var. tomentosulum j which was based on a flowering 
specimen with only half grown leaves, belongs to this species, so that now the 
pubescence of the foliage constitutes the chief character by which to distinguish 
A, longipes from ^1. cappadodcum and A, amplum*

ACERACEAE. — ACER 89 

These specimens agree well with typical A. palniatum; the leaves are generally 
seven-lobed, about 6-8 cm. in diameter with oblong-ovate, acuminate and doubly 
serrate lobes, quite glabrous beneath except tufts of hairs at the base of the primary 
veins, and slightly reticulate; the wings of the fruit measure with the nutlet 2-2.2 
cm. The Hupeh specimens referred by me previously (in Sargent, Trees and Shrubs, 
I. 179) to this species belong to the following species.

tember 1907 (No. 2050); without locality (Veitch. Exped. Nos. 538, 
540). 

Acer rohtistum differs from A. palmatum chiefly in its larger fruits and the larger 
and broader sepals and petals; the sepals and young fruits are purple. The leaves 
when unfolding are thinly covered with long hairs, but soon become glabrous ex- 
cept the bearded axils of the veins; the inflorescence is also at first slightly hairy.

On account of its pubescence this species seems most nearly related to ^1. Sieholdi- 
anum Miquel, which is easily distinguished by its seven- to eleven-lobed leaves, the 
bearded axila of the under side, the stouter petioles, the decurrent wing of the 
fruit and the absence of the waxy covering of the branches.

Closely related to A. caesium Wallich from which it differs chiefly in the broader, 
less acuminate lobes, the minute often obsolete basal lobes, the coarser and more 
remote serration and the strongly reticulate under side of the leaves. The size of 
the fruits seems to afford no distinguishing character, for I have before me Hima- 
layan specimens with fruits about 4 cm. long and Wilson's No. 4506 has fruits 5.5 
cm. long, Wilson's No. 2707 (in Herb. Kew.) from Hupeh referred by me formerly 
to A. caesium, probably belongs here.

Wilson's No. 1885, consisting only of sterile branches, is possibly a juvenile form 
of A. sinense; it differs from the typical form in its deeply divided five-lobed leaves 
with oblong, rather narrow lobes, the middle one 7-^ cm. long and 3 cm. broad. 
Apparently the same form is figured by Veitch as A. spec, (in Jour. Roy. Hort. Soc. 
XXIX. 354, fig. 99, 103). I have not been able to find among Wilson's and Henry's 
flowering and fruiting material a specimen which matches this form in the shape 
of the leaves.

Differs from the type in its smaller, three-lobed leaves with short ovate ap- 
pressed serrulate lobes narrowed into a short obtusish acumen, glabrous on both 
sides, reticulate beneath, 2.5-4 cm. long and 3.5-5.5 cm. broad; corymb small and 
few-flowered. To A, Wilsonii Rehder it seems less closely related; that species 
differs from it widely in its paniculate inflorescence, and in the entire or nearly 
entire lobes of the thinner leaves.

* The fact that certain forms of A. laxifiorum Pax and A. Maxiviovnczii Pax 
are so similar that the separation of these species becomes difficult, has made it ap- 
parent to me, that there are no characters by which to distinguish in the case of some 
of the species the section Indivisa from the section Macrantha. I refer therefore 
all species of the Indivisa Pax to the Macrantha^ except A. stachyophyllum Hiem, 
which I have already, in 1905, transferred to the section Arguta, A. distylam Siebold 
& Zuccarini, which with its paniculate inflorescence seems to find its best place m

the Macrantha by the character of the bark and particularly by the winter-buds 
which have several pairs of outer imbricate scales, while the Macrantha have only 
two valvate outer scales ; the foliage and the inflorescence of A . carpinifolium are also 
quite different from that of any species of the Macrantha. From the section 
Macrantha as understood by Pax in his monograph two species, A. parviflorum 
Franchet and A, erosum Pax, must be removed and transferred to the Spicata, the 
last named as a synonym to A. caudatum, var. muUiserratum Rchder. In the con- 
ception as now here proposed the section Macrantha will form a group of closely 
related species very uniform in the characters of inflorescence, flower and fruit.

This variety differs markedly from the type in its five-lobed leaves, but occa- 
sionally, particularly near the ends of the shoots, leaves appear which are similar 
to those of the typical form. The variety presents also some resemblance to A. Maxi- 
mowiczii Pax, but that species has the middle lobe much more elongated and 
narrower, the lateral lobes more spreading and also narrower, and the leaves are 
quite glabrous when unfolding except tufts of hairs in the axils of the veins.

Part of No. 274 represents A, teiramerumy var. lohulatum Rehder (in Fedde Rep, 
Nov. Sp. 1. 174 [1905]) which passes gradually into the type and is perhaps better 
considered only a slightly different form. This and the type are restricted to 
Hupeh. The specimens of Szech'uan differ in their leaves being generally ovate to 
ovate-oblong in outline, not or only very slightly lobed and usually 3-nerved at 
the base. In regard to other characters they show marked differences, and the 
following three varieties can be distinguished. 

Acer tetramerum, var. betulifolium Rehder, n. var.

Western Szech'uan: Sungpan, woodlands, alt. 2400-2800 m.,

of Mt. Chagolo, July 11, 1885, S. N. Potanin. Northern Shensi: 
G. Giraldi (Nos. 2118, 2119, 7137, in herb. Florence). 

With the recent material collected by Wilson in northwestern Szech'uan at 
hand I have come to the conclusion, that A. betulifolium cannot be separated 
specifically from A. tetramerum, Sungpan is situated only about 80 miles south- 
■west of the t3i>e locality and Wen-chuan Hsien about 100 miles south of Sung- 
pan, BO that apparently the variety betulifolium is restricted to the northwestern 
part of the range of the whole species. It is chiefly distinguished from the type 
by its ovate or oblong-ovate leaves, not or only very slightly lobulate, glabrous or 
glabrescent and usually three-nerved at the rounded or sometimes cuneate base 
and by the broader wings of the fruits.

(No. 8799). 

This variety is distributed from Wen-chuan southward, but does not extend 
into western Hupeh. The typical form differs from this variety chiefly in the smal- 
ler triangular-ovate leaves, more or less lobed and sparingly pubescent on both 
sides or, while young, rarely glabrescent. The variety approaches in its more ex- 
treme forms A. stachyophyllum Hiem, which differs cMefly in its leaves being 
densely villous beneath, in its larger fruits and in the often branched racemes.

Differs strikingly in its very long and slender racemes from the typical var. 
elohulalum. From forma latialatumy which has racemes of about the same length, it 
differs in the pubescent leaves and in the narrower wings generally about 1 cm. 
broad.

27 and August 1907 (No. 1815); Fang Ilsien, uplands, June 1907 
(No. 1814, as to the flowers). 

Wilson's Nos. 1814 and 1815 appear to be intermediate between V. Henryi and 
V. erubescens, and this together with the fact that these two species grow in the 
same locality where the specimens in question were collected seems to point toward 
a hybrid origin of these plants. The corolla is infundibuliform, but short, the 
tube being but little longer than the limb, while in V. Henryi it is shorter, and in 
F. erubescens about twice aa long as the limb. The inflorescence is more like that 
of the typical F. erubescens. The leaves are membranaceous like those of F. eru- 
bescenSy but are remotely serrulate or denticulate as in F. Henryi, which differs 
in its subcoriaceous generally narrower leaves, while the first named species is 
distinguished by its crenately serrate generally broader leaves. 

Viburnum erubescens Wallich, Plant As, Rar, XL 29, t. 134 (1830). 

The Chinese specimens of F. erubescens differ in several respects from the Nepal 
forms as described by Walhch, and may be here treated as varieties as follows: 

Viburnum erubescens, var. Prattii, n. var. 

Viburnum Pratiii Graebner in Bot. Jahrb. XXIX, 584 (1901). 

Western Szech^uan; Tachien-Iu, upland, alt. 2700 m., July and 
September 1908 (No. 1827); Wa-ssu country, Wen-chuan Hsien, 
thickets, alt, 1800-2100 m., June and September 1908 (No. 805); 
Nin-tou-shan, west of Kuan Hsien, alt. 2250 m,, June 20, 1908 (No. 
1824); Wa-shan, thickets, rare, alt. 2400 m., July 1908 (No. 1825); 
Mupin, thickets, common, alt. 2100-2500 m., June 1908 (No. 1826); 
northeast of Sungpan, woodlands, alt. 2100-2700 m., August 1910 
(No. 4031). 

This variety differs from the type chiefly in its broader and larger, broadly 
obovate or elliptic or rarely oblong-obovate leaves pubescent beneath, with the 
pubescence persistent at least on the veins, and in its violet-purple anthers which 
are yellow in the type. I have not seen the type specimen of Graebner's F. Prattii 
from Tachien-lu, but his description agrees perfectly with Wilson's No. 1827 from 
the same locality, and with the other specimen quoted here, as well as with 
Giraldi's specimens cited by Graebner which I have seen. 

Viburnum erubescens, var. gracilipes Rehder, n. var. 

A typo recedit praecipue foliis latioribus plerumque ovalibus basi 
rotundatis, inflorescentiis glabris laxioribus, elongatis, 7-12 cm. longis, 
floribus partim graciliter pedicellatis, tubo corollae sensim ampliato, 
calyce cupuliformi, fructibus angustioribus.

cality (Veitch Exped. No. 1382); no locality, A. Henry (No. 6543). 
Eastern Szech'uan: South Wushan, A, Henry (No. 5691). 

From the Szech'uan form this vaxiety differs chiefly in its glabrescent leaves, 
the slender and loose inflorescence with part of the flowers on slender pedicels, 
the saucer-shaped calyx with very broad, often obsolete, teeth, the yellow anthers 
and the narrower fruits. Some specimens, however, as Nos. 1814 and 1824, ap- 
proach in their narrower and more pubescent leaves the Szech'uan form, but they 
have yellow anthers, while some Szech'uan plants have a saucer-shaped calyx like 
var. graeilipes,'^

(1888), 

Western Hupeh: ravines around Ichang, alt. 30-300 m., March 
20 and July 1907 (No. 1840). 

Wilson's flowering specimen bears on its label the note "flowers wMte function- 
ally dioecious " and consists of two branches apparently from different plants and 
showing two kinds of flowers. One of the branches bears a terminal many-flowered 
panicle with the peduncle 6.5 cm. long; the corolla does not seem to be fully de- 
veloped, the lobes are upright and shghtly incurved, not spreading, the rudimentary 
stamens are about 1 mm. long with deformed dark colored and empty anthers, and 
the short thick style bears a large capitate three-lobed stigma. The other branch 
bears two small panicles, 1.5 and 2.5 cm. long, in the axils of the leaves of the pre- 
ceding year; the corolla is rotate, about 6 nmi. in diameter, with spreading lobes; 
the stamens are 4 mm. long and exceed somewhat the corolla-lobes, with yellow 
oval pollen-bearing anthers ; the style is reduced to its conical base with three minute 
blunt points at the apex; the ovary is smaller and apparently sterile. As I have 
seen no other flowering specimen of the species I do not know whether dioecious 
flowers are the rule or whether this is only an abnormal case. No other species in 
the genus Viburnum is known to have diclinous or incompletely diclinous flowers. 

Viburnum oliganthum Batalin in Act HorL Petrop, XIII. 372 
(1894). 

Western Szech'uan: Wa-ssu country, Wen-chuan Hsien, thickets,

alt. 1200-2250 m., May and August 1908 (No. 805*). 

* In connection with these varieties another very distinct variety of V, erur 
hescens from Upper Burma may be described here: 

Viburnum erubescens, var. burmanicum Rehder, n. var. 

Folia chartacea, glabra, oblonga, basi rotundata, apice subito in acumen longum 
falcatum producta, remote denticulata, 10-12 cm. longa et 4.5-5.5 cm. lata, supra 
obscure viridia, subtus pallidiora, utrinsecus 6-costata costis curvatis anasto- 
mosantibus trabiculis parallelis conspicuis conjunctis. Panicula glabra, longe 
pedimculata, late pyramidalis, &-8 cm. diam. et 4-6 cm. longa; corolla infun- 
dibuliformis limbo patulo, antheris flavis semiexsertis. 

Upper Burma: Kachm Hills, 1898. Shuik Mokim (Ex. Herb. Hort. Calcutt. in 
Herb. Arnold Arboretum), 

This very distinct form is easily recognized by its chartaceous perfectly oblong 
and quite glabrous remotely denticulate leaves and by the very broad and short 
inflorescence. 



CAPRIFOLIACEAE, — VIBURNUM 109 

The panicles in Wilson's specimens have usually from 10 to 20 flowers, while 
Batalin describes them as 7-flowered, but there seems to be no other difference 
between the Kansu and Szech'uan specimens.

and the nearly glabrous veins of the leaves.

Wilson's No. 447 agrees well with Henry's No. 11362 from Yunnan which I 
have referred to this species. V. corylifolium ia closely related to V. dilatatum 
Thunberg and may perhaps be considered a variety of it; it is chiefly distinguished 
by the long hispid pubescence of the petioles, inflorescence and young branchlets. 
It seems doubtful whether V. dilatatum occurs in western China, and the only 
Chinese specimen I have seen is from the province of Chekiang, collected near 
Ningpo by D. Macgregor (Herb. Arnold Arboretum); Wilson's No. 944 which I 
referred formerly (Sargent Trees and ShrubSf II. 114) to that species probably be- 
longs to V. bTevipes Rehder.

CAPRIFOLIACEAE. — VIBUENUM 113 

These specimena differ somewhat from the type in the leaves being sparingly 
furnished with fasciculate hairs on the whole under surface and sometimes gla- 
brous above, in the generally oblong-ovate shape of the leaves and in the stamens 
being slightly longer than the corolla lobes. The fruit is bright red, ovoid, about 
8 mm. high and furnished with scattered stellate hairs; the stone is broadly ovate, 
much compressed, pointed, one-ribbed on the dorsal and two-ribbed on the ventral 
side, about 6 mm. high and 5 mm. broad. V. hupehense Rehder, which much resem- 
bles this species in the velutinous tomentum of the inflorescence, differs chiefly in 
.the stipulate petioles and the denser fasciculate pubescence, while the leaves of 
V, Wilsonii have mostly faseiculate hairs on the upper surface while young, 
becoming glabrous at maturity and are but slightly pubescent beneath.

ber 1907 (No. 676). 

Viburnum brevipes bears in the shape of the leaves and in the very short petioles 
a great resemblance to V. erosum Thunberg, which, however, is easily distinguished 
by the stipulate petioles, by the different, not hispid, and often very slight pu- 
bescence of the inflorescence, petioles and branchlets, the absence of the glands on 
the under side of the leaves and by the smaller and less compressed stone. Its near- 
est relationship seems to be with V. dilataium Thunberg, but that species is readily 
distinguished by its much longer petioles and broader leaves and by the generally 
forked hairs of the under side of the leaves. I am inclined to refer one of Wilson's 
Hupeh specimens collected in 1900 (Veitch Exped. No. 944), which is in flower, 
provisorily to this species on account of the short petioles, but the leaves have 
the shape of those of V. dilataium. Viburnum brevipes is in cultivation and may 
be expected to flower soon.

(No. 1819). 

The Hupeh specimens difier from the type chiefly in the longer stamens, exceed- 
ing shghtly the corolla-lobes, and in the occasionally broader leaves. The fruits, 
not yet described, are ovoid and bright red; stone ovoid, pointed, 3-6 mm. high and 
4.5 mm. broad, with one dorsal and two ventral ribs; testa light purplish brown.

1908 and October 1910 (Nos. 1262, 1263, 1263% 1809, 4128). 

Wilson's No. 1043 differs rather strikingly from the type m its very small leaves 
with few veins and with few coarse or occasionally lanceolate and entire teeth, more 
pubescent corymb, smaller flowers with the stamens scarcely exceeding the corolla- 
lobes and in the smaller fniits.

No. 393 seems nearest to the type. No. 238 differs in its smaller leaves, smaller 
flowers and smaller fruits with the stones scarcely 5 mm. high and ovoid. The seeds 
distributed under the same number are different and agree exactly with those 01 
the type.

Differs from typical V. lohophyllum chiefly in the slight floccose pubescence of 
the under side of the leaves which are usually cuneate at the base. In the shape of 
the leaves it bears some resemblance to V. Wilsonii Rehder, but is distinguished by 
its quite glabrous branchlets and petioles, the only slightly pubescent inflorescence, 
the glabrous winter-buds and the only sHghtly pubescent under side of the leaves. 
No. 1812 agrees in the shape and size of the leaflets exactly with No, 1811, the 
type of this variety, while No. 1808 has smaller leaves only from 5-7 mm. long.

118 WILSON EXPEDITION TO CHINA 

The discovery of a Chinese Symphoricarpos is highly interesting, as it adds one 
more genus to the number of those formerly considered peculiar to the flora of 
North America, but in recent years foimd also in western and central China, as 
NyssGj Sassafras, Liriodendrmi, Becumaria and others. In the shape of the corolla 
S. ^nensis resembles most S, orbiculaius Michaux, but the color of the fruit and 
the terminal peduncled inflorescence distinguishes it from all American species.

Closely allied to A. uniflora R, Brown, which is easily distinguished by its sub- 
coriaceous glabrous leaves, the 1-3-flowered inflorescence at the end of elongated 
branchlets and the more campanulate corolla with a shorter and wider tube. Ahelia 
Graebneriana is somewhat variable in foliage and also in the flowers; the most dis- 
tinct forms are represented by the following three numbers: No. 267 differs in its 
narrower glabrescent leaves usually only with one to three teeth on each side, the 
narrower ones being about 4 cm. long and 1 cm. broad, in the longer sepals, the 
larger corolla, nearly 3 cm. long with longer and slenderer tube, and in the lateral 
flowering branchlets being usually reduced to fascicles of leaves; No. 2020 has 
ovate, indistinctly crenulate-serrulate leaves, obtusely acuminate, and smaller 
flowers, scarcely exceeding 2 cm. in length; No. 4380 has much smaller leaves not 
exceeding 2.5 cm. and oval sepala, the flowers are wanting. 

To this species is probably related lAmiaea serrataj var. Hegii (Graebner 
(p. sp.) m sched.) Pampanini in Ntiov. Giorn. Bot, Ital. n. ser. XVII. 722 (1910) 
from Shensi, G. Giraldi, and from Hupeh, Mts. of Fan-sien, C. Sihesin (No. 1825), 
chiefly characterized by ciliate sepals puberulous on the outside; it is possibly a 
distinct species.

Rosthom's No. 34 differs from the type specimen and from Wilson's specimens, 
which have quite glabrous brancblets in its puberulous and sparingly pilose branch- 
lets; and the inflorescence does not seem tjrpical. Henry's No. 1737 resembles 
in foliage somewhat A. macrolera (Graebn.) Rehder, but the flowers are those of 
A. Engleriana^ though borne at the end of short elongated branchlets.

Abelia myrtilloides is closely related to A. parvifolia Hemsley, which ia easily 
distinguished by its densely pubescent and glandular leaves generally broader and 
rounded at the base, the short-peduncled flowers and by its longer and narrower 
sepals. It is also allied to A. Sckumannii Rehder, which differs in its broader and 
larger usually sparingly serrate and thinner leaves pilose on the upper surface, 
and in its smaller flowers with the tube much shorter and borne on very short 
peduncles.

I have not seen the type of this species, but at least one part of the specimens 
quoted here of this apparently very variable species agrees well with Graebner's 
description. The length and shape of the sepals varies considerably; in No. 3721 
they are as long or slightly longer than the corolla-tube, linear-oblong and acutish, 
while in Nos. 2021 and 2022, they are about two thirds as long, oblanceolate and 



122 WILSON EXPEDITION TO CHINA 

obtuae. The peduncles in No. 3721 are 6-8 mm. long, in No. 2022 the pedicels are 
more or less separate so that the flowers are pedicelled and the common peduncle 
is sometimes very short, similar to the inflorescence of A, hiflora Turczaninow. 
The leaves are also very variable; in No. 2021 they are narrowly lanceolate and 
quite entire, and in No. 4210 lanceolate-oblong and nearly entire, while in No. 
2022 and in Purdom's No. 320 at least part of the leaves are elliptic and coarsely 
toothed and in No. 4492 the leaves are oblong-lanceolate and almost all serrate. 
The flowers are fragrant, the tube nearly tubular and the limb spreading.

The corolla, not described by Graebner, is narrowly funnel-form or nearly tubu- 
lar, white, 15-18 mm. long, with spreading limb, 3 mm. long; the style slightly 
exceeds the tube and the stamens just reach the mouth; the sepals are nearly as 
long as the tube or somewhat shorter. 

The determination of Wilson's collection and other unnamed material in the 
herbarium of the Arnold Arboretum led me to study all the Asiatic species, and in 
consequence to a rearrangement of the species, differing in several points from the 
grouping as proposed by Maximowicz (in Mel. Biol. XII. 473-480), Zabel (in Mitt. 
Deutsch, Dendr. Ges, II. 32-34) and Graebner (in Bot. Jahrb. XXIX. 120-145). 
To show clearly the arrangement I have adopted, a synopsis of the whole genus 
is appended here. 

SYNOPSIS OF THE GENUS ABELIA. 

Abelia has been by several writers united with Linnaea and treated as a sub- 
genus of the latter, but there does not seem to be a very convincing reason for the 
union of these two genera; there are no intermediate forms, and sufficient char- 
acters in the ovary and the fruit, as well as in the calyx and in the corolla and in 
the habit of the plants to keep Abelia as a distinct genus. At present 27 species 
of Abelia may be distinguished which can be divided into two sections well marked 
by differences in the vegetative and reproductive parts and easily recognized 
even without flowers or fruits. The first section Euabeliaj with A. ckinensis as 
the type, is characterized by the petioles not being dilated at the base and not 
enclosing the winter-buds, by the absence of recmrved hispid hairs on the young 
branchlets, the lighter or darker brown color of the bark separating in flakes, the 
more or less funnel form or nearly campanulate shape of the corolla and the 
terete or nearly terete akenes. The second section, Zabeliay which I take 
pleasure in associating with the name of H. Zabel, who first proposed a good 
division of the genus into sections, is characterized by the petioles being 
dilated at the base with the opposite ones connate and covering the winter-buds 
and persistent on the branchlets of the previous year, by the young branch- 
lets being furnished with reflexed hispid hairs or rarely glabrous, by the tubular 
corolla with spreading limb, by the stamens not exceeding the tube and the 
scarcely exserted style, and by flattened akenes usually more or less curved. The 
several subsections or series as here limited have well defined geographical ranges; 
the first, Serratae, is Japanese, the second and third, Uniflorae and Rupestres, range 



CAPRIFOLIACEAE, — ABELIA 123 

from eastern to western China, the fourth, Vesaleae, is Mexican, the fifth, Carym- 
bosae, is Central Asiatic, while the last, Biflorae, extends from Mongolia to 
western China.

Abelia serrata has sometimes been confounded with A. uniflora R. Brown, but 
that species is easily distinguished by its axiUary, one-flowered or sometimes three- 
flowered peduncles. The Chinese specimens identified by some botanists with 
A. serrata belong to A. Graehnerianxi Rehder, a species closely related to A. uniflora, 
but in foliage rather similar to A. serrata.

Graebner describes the sepals as ciliate, but I find them glabrous in Maximowacz's 
specimen, while in Watanabe's specimen of A. serrata the sepals are sparingly cili- 
ate; Arimoto'e specimen which has the sepals ciliate, is without flowers and I am 
not sure whether it really belongs here or to the following species; the akenes are 
glabrous, but also in Maximowicz's specimen they are only very sparingly pilose 
even in a young state.

I have not seen the type specimen, but Jack's specimen from Adera, which is 
without flowers, seems to agree well with Graebner's description except that the 
sepals are not strictly lanceolate.

Abelia longituba is closely related to A. uniflora, but from this and the other 
allied species easily distinguished by the long and slender tube of the corolla and 
the small leaves.

China: Fokien, Reeves (ex R. Brown), R. Fortune (ex Lindley). 

Of this species I have seen only specimens from cultivated plants which agree 
perfectly with the figure published by Hooker. According to Maximowicz the type 
specimen has smaller flowers and Lindley's figure shows the leaves slightly hairy, 
but I do not think that the type and Lindley's plant are different from the plant 
now m cultivation. Abelia uniflora has been made to include the plant of western 
China now described as A. Graeknerianaj and even the Japanese A. serrala Siebold 
& Zuccarini, but the latter differs markedly in its two-flowered terminal peduncles, 
and belongs to another group, and the former, though closely related, is certainly 
sufficiently distinct to form a separate species.

XXIX. 144 (1900). 
Linnaea (Abelia) Perringiana (uniflora X ckinensis) Graebner, l.c, 145 (1900). 

This hybrid is not uncommon in cultivation under the name of A. rupestris; 
five of the specimens before me from different gardens are named thus, while one 
is named A. uniflora and one A. ckinensis. They differ only slightly from each other 
and are all clearly intermediate between A. ckinensis and A. uniflora, and exhibit 
not the slightest trace of an influence of A. biflora which, moreover, so_far as I 
know, has never been in cultivation. The hybrid is hardier than either of its 
parents^ which accoimts for its wider distribution in our gardens. When and where 
it originated I have been unable to find out. The oldest specimen I have seen was 
collected at Kew in 18S0 by G. Nicholson under the name of A, rupestris; it may 
be the form sent out by Veitch as A, rupestris grandiflora alba according to Andre. 
The form described by Andr(5 as A . rupestris grandiflora originated in the nurseries 
of Rovelli Brothers at Pallanza, Italy. I have before me a specimen collected in 
LavalI6's Arboretum at Segrez in 1887 where it was, according to the label, received 
from RoveUi under that name. 

SPECIES TO BE EXCLUDED 

Abelia splendens Hort. ex K. Koch, Dendr. II. 1, p. 20 (as synon.) (1872) =• 
Lonicera fragrantissima lindley & Paxton. 

Abelia adenotricha Hance in Jour. Bot. IX. 132, 1871 {Linnaea adenotricha 
Graebner in Bot. Jakrb. XXIX. 144 [1900]) = Lonicera EUsae Franchet. 

Though I have not seen Hance'a specimen, I accept, after comparing his de- 
scription with Lonicera Elisaej as correct Franchet's suggestion {Plant David. 
I. 152) that Abelia adenotricha is probably the same as Lonicera EUsae. All the 
characters even including measurements agree with those of L. EUsae, and the 
pecuUar inflorescence which seemed so strange to Maximowicz {M€l. Biol. XII. 
479) may be explained, if one imagines that Hance had a specimen like the upper 
part of Franchet's figure of L. EUsae; Hance may have easily taken the solitary 
peduncle as originating between the two branchlets. Place and time of collection 
of the two species also agree. As there is no other plant among the undoubtedly 
complete set of David's plants sent to Paris and determined by Franchet, which 
corresponds to A. adenotricha, hardly any doubt seems to be left that Hance'a 
name must be referred as a synonym to L. EUsae.

which is easily distinguished by its much wider lilac corolla with the tube only 
three times as long as the Umb and not constricted at the mouth, by the 3-celled 
ovaries, the longer lanceolate calyx-teeth, the higher cupula and the larger often 
acute leaves,

Wilson's specimens differ slightly from the type in their shorter corolla tube, 4-5 
mm. long, and in their narrower and smaller leaves broadly cuneate at the base and 
usually in threes. One of the branches shows the young leaves beneath and the 
flower buds furnished with a very slight floccose pubescence which soon disap- 
pears.

Lonicera Schneideriana resembles in foliage L. szechuanica Batalin, which differs 
in the stamens being shorter than the corolla-lobes, in the longer bracts and in the 
glabrous style. Lonicera shensiensis Rehder is distinguished chiefly by the shorter 
stamens and the presence of bractlets, while L. serpyllifolia Rehder differs in the 
smaller somewhat hairy leaves, the ovate bracts and shorter peduncles. No. 1859 
differs from the type in the generally oblanceolate leaves, 2-3 cm. long. No. 1860 
is still more different but hardly sufficiently different to be made the type of another 
species; it has a shorter distinctly gibbous corolla, shorter calyx and glabrous 
style, but otherwise, particularly in the foliage, the short bracts and in the slightly 
exserted anthers, it agrees with the type. 

I take pleasure in associating with this species the name of Mr. C- K. Schneider, 
whose Illustrierfes Handbuck der Laubholzktinde contains many valuable contnbu- 
tions to the knowledge of Chinese trees and shrubs.

One of Wilson's specimens with unripe fruits fortunately had a single pair of

sparingly pilose or glabrous; bracts linear-lanceolate exceeding the minute and 
indistinctly toothed calyx; bractlets wanting; corolla tubular, 10-12 mm. long, 
slightly gibbous above the base, glabrous outside, sparingly hairy inside below the 
stamens; lobes orbicular-ovate, about 1.5 mm. long, upright; stamens inserted 
somewhat above the middle, filaments very short, anthers oblong, 3 mm. long, not 
reaching the base of the hmb; style exserted, very sparingly pilose below the middle.

The chief difference between this variety and the type lies in the generally 
larger, more oblong-ovate leaves, their softer pubescence, the narrower bracts and 
the less setose corolla. 

As I have stated before (Rkodora, XI. 210), the section Vesicariae proposed by 
Komarov and adopted by me in my Synopsis of the genus must be united with the 
Chlamydocarpi; the cupula is not adnate to the base of the calyx, only firmly ad- 
hering by matted hairs, and splits at maturity disclosing the bright red berries.

As the mature leaves and fruits of this species have not been described, their 
description may be given here: Leaves oblong or obovate-oblong, acutish or ob- 
tuse and mucronulate, broadly cuneate at the base, 2-3 em. long and 8-15 mm. 
broad, minutely velvety on both sides, margin revolute, dark green above, netted 
with paler veins, paler green beneath and reticulate; petioles 1-2 cm. long, puberu- 
lous. Fruits on very short peduncles 1-3 mm. long, ovoid, longer than the bracts 
deciduous at maturity, bluish black, usually with 3-8 seeds; seeds irregularly 
triangular-oblong, lustrous, dark brown, 4.5 mm. long. 

This and L. cyanocarpa Franchet are so far the only species known of the Brae- 
teatae which have blue or bluish black fruits. Lonicera cyanocarpa, of which the 
flowers are unknown, is apparently closely related, but easily distinguished by the 
narrower and somewhat larger coriaceous leaves, setulose-ciliate on the margin and 
by the ovate-lanceolate acuminate and ciliate bracts. When in fruit L. miiia looks 
in general appearance so much like L. coerulea that it might be taken for that 
species if it were not for the distinct berries.

variety or may also occur on vigorous branches of the type.

Lonicera subdentata seems most nearly related to the preceding species and to 
L. scabrida Franchet, but ,both these species have the branchlets furnished with 
reflexed setose hairs. Lonicera praecox Rehder, which is somewhat similar in foliage 
and in its glabrous branchlets, is easily distinguished by the winter-buds having 
several outer roundish scales and by the glabrous ovaries.

h 

This species forms with L. Wehbiana Wallich, L. keterophylla Decaisne, L. 
keteroloha Batalin, L. tatsienensis Franchet, and L. perulata Rehder a group of very 
closely related species. The first differs chiefly in the glandular pubescence, pale 
flowers and broader not acuminate partly reflexed bud-scales; L. keterophylla in 
the quite glabrous foliage; L. heieroloba and L. tatsienensis differ in the smaller re- 
flexed bud-scales, in the smaller leaves being pilose on the whole under surface and 
usually rounded at the base and in the shorter bracts; L. perulata \s easily distin- 
guished by its numerous obtuse bud-scales. From ail these species L. mupinensis 
differs in its upright lanceolate acuminate bud-scales; in the shape of the leaves and 
in the amount of pubescence it seems rather variable.

In the shape of the foliage this variety resembles very much L. fuchsioides 
Hemsley, but that species is easily distinguished by the perfectly glabrous branch- 
lets and inflorescence, by the larger flowers and by the looser and more elongated 
terminal inflorescence. No. 1879 forms a transition to the type, as the leaves of 
the lateral flowering branchlete are narrower, often slightly ciliate, and pubescent on 
the midrib beneath.

A very distinct variety, chiefly differing from the type in the very narrow, mem- 
branaceous, light green leaves. 

Lonicera fragrantissima Lindley & Paxton, Flow. Gard. III. 75, fig. 268 
(1852). 

Kwangtung: Ningpo, D. Macgregor. 

If this specimen has been really collected from a wild plant, as it appears to 
have been, it would settle the question of its habitat, as L. fragrantissima has been 
known only as a cultivated plant. 

Lonicera montigena Rehder, n. sp. 

Frutex erectus, circa 5 decim. altus, ramulis junioribus breviter pubescentibus

Allied to L. kispida Pallas, which differs chiefly in the larger winter-buds, in the 
absence of the glandular pubescence on the leaves, bracts and branchlets, in the 
larger corolla only sparingly hairy outside, in the filaments being longer than the 
anthers and in the pilose style. Lonicera nuhigena Hehder, distributed under the 
same number, is easily distinguished by its much shorter corolla, the tube being 
only 1 cm. long, the anthers not exceeding the mouth and the style only half as 
long as the tube: it is a lower and more densely branched shrub and more alpine 
in its general aspect than L. montigena.

The form from Corea which I recently described as L. leptantha cannot be spe- 
cifically separated from L, Tatarinoviiy as a comparison with good flowering material 
recently received from Chili shows; it is hardly different enough to be separated 
as a variety. The ovaries of the species are usually two-thirds connate, occasion- 
ally only at the base, and the bractlets are connate into a cupula, not distinct, as 
stated in my Synopsis of the genus.

DEUTZIA Thunb-i 

Determined by Alfred Rehder. 

After the publication of my Synopsis of the Chinese Deutzias (see p. 15-25) I 
had the opportimity of examining the material of this genns in the Herbarium of 
the Museum d' Histoire Naturelle at Paris, where I foimd several imdescribed 
species; and a further examination of our imnamed specimens of the Henry col- 
lection resulted in bringing to light several Deutzias, three of which proved to be 
undescribed. The descriptions of these new species and varieties are published 
here as a supplement to my Synopsis of this genus, 

7, Deutzia pilosa Rehder. See p. 18.

Kwei-chau: Kwei-yang, "mont du College ^la cascade," May 18, 1898, E. 
Bodinier (No. 2216, in Herb. Mus. Paris). 

This variety differs from the type chiefly in the shorter and paler yellowish 
pubescence, in the hairs of the lower surface having generally 6 rays and in the 
larger inflorescence. No. 2216 is represented in the Herb. Mus. Paris by two 
specimens, one having broader ovate leaves, the largest being 6 cm. long and 4 
cm. broad, the other having smaller ovate-oblong leaves.

SAXIFRAGACEAE. — DEUTZIA 147 

Allied to D. setchiienensis Franchet which differs in its narrower thinner leaves 
rounded or broadly cuneate at the base, not ruguloae above, greenish and not reti- 
culate beneath and more closely and less densely pubescent, in its shorter broadly 
triangular and not purple calyx-teeth and in the larger flowers. 

8c. Deutzia Bodinieri Rehder, n. sp. 

Frutex parvus ramis erectis gracilibus fuscis, hornotinis sparse stellato-pilosia;

Kwei-chau: steep river-banks, one day's journey from Hin-y-tien, April 11, 
1897, E, Bodinier (No. 1540, in Herb. Mus. Paris). 

Most nearly related to D. Fargem. Franchet and D. setdmenensis Franchet; 
the first differs in its thicker, chartaceous and denticulate leaves, nearly glabrous 
above and furnished beneath with hairs having 6-7 rays and in the much larger 
and looser inflorescence, while D. setchuenensis is distinguished by the denser pubes- 
cence, the denticulate leaves bearing on the lower surface hairs with usually 6 rays 
and a central ray, and by the larger inflorescence; D, setchuenensis var. longidentata 
Rehder, which resembles D. Bodinieri in the serration and pubescence of the leaves 
except that the hairs beneath have sometimes 7 or 8 rays, differs further in the 
elongated teeth of the filaments. 

8d. Deutzia lancifolia Rehder, n. sp.

Kwei-chau: around Kwei-yang, "mont du College," end of April 1898, /. 
Chaffanjan {E, Bodinier, No. 2223, in Herb. Mus. Paris). 

Easily distinguished from the allied species by the very narrow ^^^^es; its 
nearest relation is apparently with D. setchuenensis , var. longidentata Rehder, which 
differs in its hroaHpr mpmhrfl.nAnn« leaves with the Stellate hairs beneath havmg

usually 6 rays and in the longer teetli of the filaments. Deutzia Fargesii Franchet 
is easily distinguished by the broader less finely serrate leaves with the stellate 
hairs beneath having generally 6 to 7 rays and by the many-fiowered inflorescence. 

10b. Deutzia crassifolia Rehder, n. sp. 

Frutex metralis ramis ut videtur erectis; ramuli hornotini sparse stellato-pilosi, 
annotini glabri v. glabrescentes, purpureo-fusci, epidermate lamellis tenuibus

desideratur. 

Yunnan: Mengtze, north mts., alt. 2000 m., A. Henry (No. 10978, in Herb. 
Arnold Arboretum). 

Most nearly related to D. coriacea Rehder, which is easily distinguished by its 
spinosely dentate leaves glabrous and smooth above and borne on longer petioles. 

Deutzia crassifolia, var. humilis Rehder, n. var. 

A typo recedit praecipue foliis angustioribus minoribus, inflorescentiis pauci- 
floris filamentis angustioribus. Frutex humilis ramis divaricatis brevibus; ramuli

3 mm. longi. Capsula matura desideratur. 

Yunnan: Szemao, mountain forests, alt. 1600 m., A. Henry (No. 10786, in 
Herb. Arnold Arboretum.) 

Most nearly related to D. Fargesii Franchet, which differs in its narrower and 
smaller leaves glabrous above and with the hairs beneath having 6-7 rays and in 
the much larger and looser inflorescence. The inflorescence of D. Henryi is borne on 
short branchlets with undeveloped leaves springing from the end of shoots with 
mature leaves, rarely axillary; this would tend to show that the foliage is persistent 
and that the flowers appear very early in spring, but the whole appearance of foliage 
and inflorescence suggests more a case of abnormal autumnal flowering. 

196. Deutzia aspera Rehder, n. sp. 

Frutex ramis robustis erectis; ramuli hornotini annotinique verrucis in apice 
pilos stellatos gerentibus dense obsiti ideoque asperi; gemmae perulis lanceolatis 
acuminatis parce stellato-pilosis v. exterioribus fere glabris. Folia decidua, ovato- 
oblonga v, elliptico-ovata, acuminata, basi late cuneata, rarius rotundata, argute 
serrulata, 3-5 cm. longa et 1.5-2 cm. lata, supra obscure viridia, venis venulisque 
impressis et pilis sparsis 4r-6-radiatis conspersa, subtus viridia, sparsissime pilis 
8-10-radiatis et papillis crebris praedita, nervis utrinsecus 5-6 subtus elevatis; 
petioli circiter 5 mm. lon^, stellato-pilosi. Inflorescentia corymbosa, convexa, 
multiflora, dense verrucosa ut ramuli, in apice ramulorimi elongatorum sessilis; 
flores desunt. Capsula pedicello 5-8 mm. longo circa medium bracteas lineari- 
lanceolatas gerenti insidens, subglobosa, pilis stellatis minutis obtecta, circiter 5 
mm. diam., calyce stylisque persistentibus coronata; calycis dentes lanceolatae, 
acuminatae, 2.5 mm. longae; styli plerxunque 4, rarius 3, circiter 3 mm. longi. 

Yunnan: south of Red River from Mamnei, alt. 2000 m., A. Henry (No. 9475, in 
Herb. Arnold Arboretum). 

Most nearly related to Z). discolor Hemsley, but easily distinguished from that 
species and its allies by the leaves being only sparingly furnished with stellate 
hairs beneath and therefore green, and by the rough branchlets. In its sparingly 
pubescent leaves it resembles D. purpurascens (Franchet) Rehder, which differs 
in its stellate hairs having only 5 to 7 rays.

Most nearly related to D. hngifolia Pranchet, which is easily distinguished by 

the close whitish tomentum of the under side of the narrower leaves, the usually 
close whitish tomentum of the calyx, and the shorter calyx-lobes. In the pubes- 
cence of the imder side of the leaves it resembles D. glomendiflora Franchet, but in 
that species the hairs of the imder side have only 4 to 5 rays, the leaves are smaller 
and narrower and the flowers white and the calyx-lobes shorter. By Franchet 
the specimens quoted above had been referred to his D. longifoliaf while I had taken 
the specimen from Fang-yang-chang, of which I had received some fragments from 
Paris as typical D. longijoliaj for D. glomeruliflora,

Hupeh: " Monte Si-ho," July 1909 C.Silvesin, (Nos. 3001, 3001^ ex Pampanini), 
This species, of which I have seen no specimen, seems most closely related to 
D. glabrata Komarov, but it is easily distinguished by the sessile or connate leaves. 

With the species enumerated and described above the total number of species 
of the genus DeiUzia occurring in China reaches 41. Besides these 6 others occur 
in eastern Asia and in the Himalayas, which are all mentioned in my Synopsis 
except D. uniflora Shirai (in Tokyo Bot. Mag. XII. 110, t. 5 (1898)) which seems most 
nearly related to D. grandiflora Bunge, but differs in its one-flowered lateral in- 
florescence with only small or without any leaves at the base; by the latter character 
it approaches D. coreana L^veill^, but that species is easily distinguished by the 
ovoid calyx-tube with short triangular lobes, the very short pedicels not exceeding 
the bud-scales and by the hairs of the lower surface of the leaves having generally 
5 rays. 

One more species forming the section Neodevizia occurs in Mexico; this is 
D. mexicana Hemsley including D. mexicanaj var. Pringlei Schneider originally pro- 
posed as a distinct species by the same author. The whole genus, therefore, con- 
tains at present 48 species.

Western Szech'uan: uplands around Sungpan, alt. 3700-4300

I refer this black-fruited specimen not without hesitation to R. humile; in the 
type-specimen the fruits are described as orange on the label, but the specimen 
was collected in June and the fruits are apparently immature. In size, shape, 
serration and the perfect glabrousness of the leaves and in the usually solitary very 
short-stalked fruits No. 4504 agrees exactly with the type specimen of R. humile.

Our specimen is from the same region as the one described by Schneider, and 
agrees well with his description, but is rather less hairy. Schneider expresses doubt 
whether his specimen should be regarded as a variety of CoUyneaster disticha or of 
Cotoneaster Simonsii Baker. Our specimen is certainly not referable to Cotoneaster 
Simonsii and shows a closer relation to Cotoneaster disticha.

ably from the district of Mupin in western Szech'uan that David sent the seeds 
from which the plants on which the species was based were raised.

This small-leaved form of €. horizontalis is the common Cotoneaster of the moor- 
lands in western Hupeh, being abundant in open rocky ground. It is probably 
merely a climatic form of the type, since the seedling plants under cultivation 
have the larger leaves of the type. 

With its small leaves this variety bears some superficial resemblance to CTnir 
cropkj/lla Wallich, and has been confused with this species by several botanists. 
The true C. micropyhlla which belongs to the sect. Chaenopetalum ia readily distin- 
guished by the spreading white petals of its flowers and the thick coriaceous leaves 
glaucous and usually whitiah-tomentose on their lower surface.

Western Szech'uan: Tachien-lu, rocky places in alpine regions, 
alt. 2800-3230 m., June and September 1908 (No. 2187; fruits bright 
red); Tachien-lu, uplands, alt. 2800-3500 m., October 1910, (No. 4136; 
prostrate over rocks, fruit red). 

Cotoneaster adpressa ig imdoubtedly closely related to C. horizontalis Decaisne, 
but seems to differ sufficiently to be considered specifically distinct. The chief 
differences are the nearly glabrous thinner leaves usually somewhat wavy on the 
margm, the larger subglobose fruits ripening several weeks earlier than those of 
C. honzontalis, and the habit, the creeping and often rooting stems being u-regularly 
branched with often tortuous or flagellate branchlets forming a dense carpet closely 
appressed to the ground, while m C. horizontalis the stems are horizontaUy spreading 
or procumbent with the straight spreading branchlets regularly diatichoua.

Allied to Cotoneaster disticha Lange, which is readily distinguiahed by its ciliate 
leaves, dull and hairy above, longer peduncles, ovoid fruit, and by the very regular 
distichous ramification of the stems. Our specimens bear ripe fruit, but are so dis-

This species is most nearly related to C. Simonsii Baker, from which it is readily 
distinguished by its smaller leaves, constantly fewer flowered racemes, less acu- 
minate sepals, and by its ovoid darker red fruits; in habit and general appearance 
the two species are very distinct. It seems also related to C. mucronata Franchet 
from Yunnan, which differs chiefly in the lax 2-4-flowered racemes and more 
densely haiiy leaves. No. 2167 from Szech'uan has the leaves, particularly those 
of the shoots, somewhat larger than the type and often shortly acuminate.

1883. The typical form is absent from central and western China. This species 
is not to be confounded with C. acutifolia Lindley which is C. ludda Schlechtendal, a

Allied to Cotoneaster acuiifolia Turczaninow, which is readily distinguished by its 
generally ovate much less pubescent leaves and more densely pubescent calyx. 
From Cotoneaster moupinensis Franchet this new species is easily recognized by 
its smaller foliage, which hardly ever shows any tendency to become rugose, its 
smaller inflorescence and flowers, and by its globose fruit. 

It must be confessed, however, that there is a great similarity between all these 
black-fruited Cotoneasters from China. With Cotoneaster acuiifolia Turczaninow 
at one end of the chain and Cotoneaster moupinensis Franchet at the other it ia 
almost possible, with the material before us, to connect the whole series. The 
living plants look quite different, and since all the species and varieties named 
above are m cultivation, it may be possible later to determine their aflfinities more 
accurately, 

Nos. 1270 and 2178 differ from the type in their thicker, broader leaves. No, 
2178 has a more numerous-flowered corymb, broader sepals, showing some approach 
to Cotoneaster moupinensis Franchet.

those of Cotoneaster hullata and the fruits are jet black. Franchet does not give the 
color of the fruits in his original description of Cotoneaster moupinensis, but from 
fragments we have, kindly communicated from Paris, they appear to us as if they 
would be black when mature. Since the leaves and flowers of this black-fruited 
variety agree exactly with Franchet's original description, and, since this is the 
common plant of the region Franchet's type came from, we have referred his 
name to tins plant and accepted Bois* name of bullata for the red-fruited form, 
which differs besides in the smaller flowers and decidedly more wrinkled leaves; 
it is, too, a comparatively rare plant, though scattered over a wide area in western 

Szech'uan. 

Our specimens exhibit considerable variation both in foliage and in size of the 
corjTnb. No. 857, from Mupin, has rugose leaves, but this character varies con- 
siderably even on the same shoots,

This variety resembles in its many-flowered corymbs C hullata, f. florihunda, 
n. comb. (C. moupinensiSy f. floribunda Stapf), which is easily distinguished by its 
much smaller leaves generally ovate or sometimes obovate and rounded at the

Yunnan; This description is drawn up from specimens made from plants in

alt. 1600-1700 m. (Veitch Exped.; type in Herb. Arnold Arboretum); mountains 
north of Mengtze, A.Henry (No. 11341). 

Closely allied to Cotoneaster Franchetii Bois, which is distinguished by its lax 
spreading habit, larger cymes, longer peduncles and longer pedicels and by its 
broader, less acuminate sepals. The living plants show greater differences than 
the herbarium material would lead one to suspect. Henry's No. 10785 has longer 
leaves and glabrescent sepals and is evidently from a vigorous plant.

This western plant shows marked difference from the type and in several respects 
approaches Cotoneaster Franchetii Bois. It also has affinity with Cotoneaster 
Zahelii Schneider. Its thinner yet more persistent leaves, smaller pendulous fruit, 
brick or orange-red, distinguish this variety from the typical form.

Thi3 is the common CoUmeaster of the thickets in western Hupeh. The oval- 
elliptic leaves are usually rounded and emarginate or mucronulate but occasionally 
acute; often all forms are found on the same shoot. The Hupeh specimens appear 
to have rather shorter, more prominently veined leaves than those from Shensi, 
the type locality. Purdom's specimen from the Tai-pei-shan has the corymbs 
larger and more numerous flowered and larger leaves than any of the other speci- 
mens we have seen. In young plants the leaves are mucronulate and inclined to 
be acute.

In the absence of ripe fruits the affinity of this species remains doubtful. It 
seems to be most closely related to the black-fruited C melanocarpa Loddiges, which 
differs chiefly in its broader and larger, differently shaped leaves, often narrowed 
at the base, sparingly hairy on the upper surface while young and with a looser 
whitish tomentum beneath. Specimens of the forms from the Altai mountains 
usually referred to C. melanocarpa resemble our species in their smaller leaves, 
which, however, are hairy on their upper surface while young, oval in outline and 
generally broadly cuneate at the base. Cotoneaster gracilis also shows some re- 
semblance to the red-fruited C integerrima Medikus, which is easily distinguished 
by its larger acute or acutish leaves, smaller and shorter racemes, larger flowers 
and stouter branches. Cotoneaster Zabelii ^Schneider differs more widely in its 
densely villous calyx and the larger leaves, hairy on their upper surface at least 
while young. — The specimen from western Szech'uan (No. 2169) has smaller 
leaves than the type and fewer flowers in shorter racemes, while the specimens 
from Shensi are almost intermediate between the Hupeh and the Szech'uan 
epecimens.

This ia a common shrub in the dry, arid river valleys of western Szech'uan. 
In No. 1317 the fruits have usually only one stone and the hypostyle covers about 
one half of it all around, while in No. 4015* usually two stones are present with 
the hypostyle covering about one third of the dorsal side.

This variety approaches Cotoneaster racemiflora, var. soongorica in the character 
of its pubescence, but the small, ovoid fruits easily distinguish it from this and all 
other forms of Cotoneaster racemiflora. It may possibly be a distinct species.

This species seems most closely related to C multiflora Bunge, but is easily dis- 
tinguished by the densely tomentulose lower surface of the leaves, the villose in- 
florescence and by the small hypostyle of its stones. From C. racemiflora K. Koch 
it differs in the larger flowers, longer stamens with yellow anthers, larger globose 
fruit, and by the hypostyle covering only the flattened apex of the stones.

In the original figure of Cotoneaster multiflora Bunge the fruit is shown as oblong- 
ovoid, whereas in the Chinese specimens the fruit is globose when mature but 
elongate in early stages of development. We rather suspect the figure cited above 
as made from immature specimens. 

In Shensi this species is apparently very common. In western Szech'uan it is con- 
fined to dry warm river-valleys and is not common. In both the Shensi and Sze- 
ch'uan specimens before us the mature leaves are glabrous and subglaucescent 
below.

Western Szech'uan: Valley of Min river near Sungpan Ting,

This variety differs from the type chiefly in the larger and comparatively 
narrower leaves being slightly hairy on the lower surface, and in the larger fruits. 
In the character of its leaves it resembles very much a flowering specimen from the 
Caucasus we have before us. On accoimt of its large and copiously produced fruit 
it is very ornamental. No. 0329 of Wilson's photographs represents the shrub in 
full fruit from which the type specimens were taken.

but it seems most nearly related to C. racemiflora K. Koch from which it differs 
chiefly in the usually acute or even short-acuminate leaves, the nearly black, usu- 
ally soUtary fruits and the narrower stones.

Apparently most closely allied to C. sa^ici/oita'Franchet and particularly to the var, 
Pritzelii Schneider, which differs, though its leaves are glabrous or nearly so at 
maturity, in the pubescent branchlets and inflorescence. Cotoneaster glaucophylla 
Franchet is easily distinguished by its shorter ovate or oval leaves.

, In Franchet's original description, cited above, the leaves are given as J cent, 
broad. This is probably a clerical error for 1-2 cent, broad. The fruits not de- 
scribed by Franchet are ovoid, about 4 mm. long and 3 mm. across, scarlet; stones 
2-3, 3 mm. long, with the style at the apex of the inner surface, and the glabrous 
hypostyle covering one half or slightly more of the dorsal side, the hypostyle dark 
brown, the lower part light brown.

Our apeclmena have shorter leaves and smaller corymbs than those described for 
the type by Pritzel, otherwise they agree exactly with his description. From the 
typical Coioneaster salicifolia this variety is distinguished by the more lanuginose 
shaggy pubescence of the lower surface of the leaves and of the branchlets, the 
duller green and smaller, comparatively broader leaves and the larger fruits with 
usually 2 stones, the hypostyle covering less than one half of the dorsal side.

seeds collected in Veitch Expedition; specimens from Hort. Veitch, June 19H| 
No. 1315, type; mountains north of Mengtze, A. Henry (No. 10785), 

A handsome species most closely allied to C. coriacea Franchet, which has obo- 
vate, roimded more coriaceous leaves. In Henry's specimen the leaves are rather 
smaller, more obtuse, and the calyx shows a tendency towards becoming glabrescent. 
From C. pannosa Franchet, with which it has been confounded in cultivation, 
its larger, more coriaceous, shining green leaves and larger corymbs readily dis- 
tinguish it.

m. tall). Eastern Szech'uan: South Wushan, mountains, 1900 
(Veitch Exped. No. 1384, flowers and ripe fruit; bush 3 m.)- 

In its much larger leaves, pubescent on both surfaces and of softer texture, in its 
more densely villose branches and ovoid fruits, this Hupeh plant differs distinctly 
from Cotoneasier salicifolia Franchet and its varieties. It seems better to regard 
it as a distinct species rather than an extreme form of that species. 

We have given a complete description of this species, since Schneider, when he 
established it as a variety of Cotoneaster rugosa Pritzel, gave only a few distinguish- 
ing characters. In Fedde's Repertorium cited above, Schneider refers this plant 
to the typical Cotoneaster salicifolia Franchet, a view which to us is quite untenable. 

On No. 1384 (Veitch Exped.) Schneider Q., c.) based his Cotoneaster rtigosa, var. 
Pritzelii, The specimen in the Herbariiun of the Arnold Arboretum bearing that 
number is typical Cotoneasier Henryana and does not in the least agree with Schnei- 
der's description. The only specimen we have seen which shows any approach to 
Schneider's var. Pritzelii is from a plant cultivated in the Veitchian nurseries and 
distributed under the name of Cotoneaster rugosa^ var. Henryi,

A strikingly distinct species, most nearly related to C. salicifolia Franchet, from 
which it is easily distmguished by its strongly wrinkled leaves densely clothed with 
thick yellowish tomentum beneath, by the similar tomentum of the branchlets and 
by the pyriform fruit with 3 or 4 stones.

The character on which Schneider founded this variety breaks down, but the 
long peduncles and pedicels and constantly one or two flowered racemes separate 
it from the Hupeh form. The Hupeh plant has constantly shorter pedicels and 
peduncles. Schneider^s original description of the inflorescence fits the variety 
better than it does the type judging by the specimens we have before us. 

The fruit is globose and bright scarlet, and the normal habit of the plant prostrate 
and rooting. When hanging down free from the soil over cliffs the rooting habit 
is arrested.

and at midsummer are distinctly villose especially on the midribs and veins, and I 
have given it a name in spite of the absence of flowers.

Western Hupeh: Fang Hsien, thickets, alt. 2200 m. May 27

This plant is of special interest because it is the first species of the great American 

group of Tomentosae which has been found in the Old World. It thus forms another 

important link between the floras of eastern Asia and eastern North America. 

It has the small late flowers, the small, soft and succulent fruit, and the obtuse 

nutlets deeply grooved on their inner faces, peculiar to the American species. The 

thin leaves with veins only slightly impressed on the upper surface place it with 

C. tomentosa Linnaeus and the other thin-leaved species of the group which are 

abundant in the Mississippi valley but are rare east of the Appalachian Mountains 

and do not extend to the Rocky Mountains. 

A photograph of C. Wilsonii will be found under No. 082 of Wilson*s photo- 
graphs.

Often cultivated for its fruit in the neighborhood of Peking and in Korea. 

This plant does not appear to be known in a wild state. It is aborescent in 
habit, while the type is usually shrubby; the leaves are larger and the much larger 
fruit is distinctly obovate, not short-oblong as in the type. With our present 
knowledge of the Chinese Crataegi it seems best, however, to consider this a vigor- 
ous large-fruited form developed by selection and long cultivation.

Eastern Siberia: bottom-lands of the Chita River, Chita, C. S. Sargent, 
August 12, 1903. 

The shape of the leaves of this plant suggests a small-leaved form of C. pinnati- 
Ma Bunge which does not appear to extend as far east as the valley of the Chita 
River, but the cavities in the ventral faces of the nutlets separate it from that 
species and place it with the Oxyacanthae. The shape of the leaves is so different 
from those of all forms of the species of this group that even without the flowers I 
do not hesitate to describe it. Geographically C. chitaensis is of considerable in- 
terest as it is the only species of this group reported from eastern Asia.

No. 3518"). 

This western Chinese species is readily distinguished from the insular Osteo- 
meles anihyllidifolia Lindley by its smaller and narrower leaves, smaller flowers, 
glabrescent calyx and glabrous fruit. Osteomeles suhrotunda K. Koch in Ann, 
Mils. Lnigd.-Bai. I. 250, figiu-ed in Hooker's Icon. XXVII. t. 2644, appears to be 
more closely related to 0. anihyllidifolia Lindley than to O. Schwerinae Schneider. 

In our No. 1016 the calyx is glabrous or nearly so and the sepals shorter than 
in the type. No. 3518 Veitch Exped. has much larger flowers than the type and 
they are conwnonly solitary. 

In Szech'uan this plant is restricted to the river-valley where a dry, hot climate 
obtains.

A very common evergreen bush or small tree throughout the warm-temperate 
parts of China, varying considerably in the size and shape of its leaves. The 
only figure we have found of the true Photinia glabra Maximowicz {Crataegus 
glabra Thunberg) is published by Shirasawa, Icon. Ess. For. Jap. 1. 83 t. 47, fig. 13-24 
(1900). All the early figures appear to us to belong to the Chinese plant, Photinia 
serrulata Lindley. 

It is possible that Henry's Yimnan specimens, which are all in fruit, belong to 
Photinia Lindleyana Wight & Arnott, but the distinctions between these two 
species are not very obvious.

in diameter, perfectly glabrous and somewhat thicker leaves, the petioles 2-4 em. 
long, perfectly glabrous shoots and inflorescence, smaller flowers about 6-7 mm. m 
diameter and smaller ovoid fruits about 5 mm. in diameter, with the branches of 
the inflorescence shorter, rather thick and angular in the dried state. 

This new Photinia is one of the handsomest evergreen trees in central Chma 
and is commonly planted around shrines and tombs. The short interior branches 
are frequently spinescent. The name "Tung-ching" (winter-green) is sometimes 
applied to this tree, but this name properly belongs to Xylosma racemoaum Miquel.

465, flowering branch only; bush 3 m. tall, flowers white); without 
locality (Veitch Exped, No. 714, fruiting branch only). 

Schneider placed this speciea into Siranvaesia probably on account of its live 
styles, but neither the number of styles nor the greater or lesser degree of union 
between the back of the carpels and the calyx-tube can be made a character of gen- 
eric distinction between the genera of the Pomaceae. The fruit seems to us to agree 
exactly with that of the section Pourihiaea of Photinia except in the complete union 
of the carpels to the calyx. It has the same granulose flesh, thin papery walls, 
not separating or sphtting and no central cavity, at least we have not been able 
to detect in the fruit or in the young ovary the free central space as found in Stran' 
vaesia. In the scarlet color of the fruit and the rugulose or verruculose epidermis 
it agrees also with Photinia, while Stranvaesia has an orange-red or coral-red fruit 
with smooth epidermis. Schneider refers to this species a fruiting specimen col- 
lected by A. von Rosthom, and ^ves the measurements of the fruit as 9: 8 mm., 
but in our specimens the fruits measure about 14 mm. in diameter; they are sub- 
globose, dark scarlet, very sparingly villose or nearly glabrous except at the apex; 
the persistent calj^x-teeth are incurved; the apex of the core is villose and almost 
flat; the granulose mesocarp does not separate clearly from the endocarp, which ia 
6-celled with thin papery walls; the seeds are about 6 nun. long, oblong-obovate, 
narrowed at both ends, particularly at the almost stipitate and slightly curved base. 

Here may be added the description of three new species based on material of 
other collections than those of the Arnold Arboretum Expedition.

A very distinct species which seems nearest to Eriohotrya prionophylla Franchet. 
In general appearance it greatly differs from all other Photinias. The leaves 
particularly by their venation recall those of Eriobotrya, but are much smaller, and 
the inflorescence bears some slight resemblance to that of Raphiolepis. It may not 
belong to Photinia at all, but as long as the fruit is unknown, it may provisiongtUy 
find its place here, as it agrees in the structure of its flower perfectly with Photinia,

ROSACEAE, — ERIOBOTRYA 193 

An exceedingly common shrub in Hupeh and very variable. It is distinguished 
from the type by its usually much smaller leaves and nearly glabrous flowers, but 
some specimens before us have leaves nearly as large aa those of the type and are 
only slightly less hairy; it seems questionable whether the form is entitled even 
to varietal rank, ' 

Here may be added the description of a new variety from Yunnan of Stran- 
vaesia nussia Decaisne {S. glaiicescens Lindley).

A typo recedit foliia longis petiolatis angustioribus et longioribus, plerumque 
oblanceolatis v. oblongo-oblanceolatis 8-15 cm. longis et 2-4.5 cm. latis, inflorescentiis

^his variety serais to resemble in the shape of its leaves S. nttssia, var. angusti- 
folia (Decaisne) Schneider, which we have not seen, but which we must assume has a 
villose inflorescence, as Decaisne gives the narrower leaves as the only distinguishing 
character.

Very generally cultivated throughout Hupeh and Szech'uan, also spontaneous 
on the cliffs around Ichang. 

The fruit of E. japonica is figured by Decaisne without calyx and described as 
umbilicate at the apex; Schneider also states that the calyx is deciduous and figures 
the fruit exactly as Decaisne does. We find in our specimens a i)ersistent calyx 
With incurved teeth which agrees with the figures quoted above and with other 
hgures we have seen. Also the other species of this genus have, as far as we have 
seen fruits, a persistent calyx.

ch'uan: Tung Valley, on cliffs, alt. 800 m., May 1904 (Veitch Exped. No. 3507). 

A well-defined species with leaves which recall those of Quercus Prinos Linnaeus. 
In the shape and serration of the leaves it resembles E. bengalensis Hooker f., 
which is easily distinguished by the glabrous lower surface of the leaves. From 
E. japonica Lindley and E. grandiflora it differs distinctly in the structure of its 
ovary which is adnate to the calyx-tube only in the lower half, the upper free part 
being densely villose, while in the former two species the ovary is entirely inferior 
and glabrous at the apex. The presence of two or three styles nearly free or con- 
fluent to above the middle is interesting and further proves the instability of this 
character in the genus.

This species differs from P. conadenia Koehne in the narrower leaves and the

on the label as dark red, and in No. 4013 aa nearly black, but also in No. 4013 it ap- 
pears to be dark red in the dried state. The really black fruits, as in. P. pleuroptera

This species resembles in its pubescence P. pulchella Koehne, but P. pulchella 
has longer racemes and the glands of the teeth of the leaf are very small. Prunus 
pleiocerasus Koehne and P. conadenia Koehne differ in being glabrous and in their 
longer racemes with more flowers. In its short racemes P. macradenia Koehne, 
somewhat approaches P. tatsienensis Batahn, which differs, however, in the 2(-4)- 
flowered umbels and in being glabrous.

beajs on the teeth of the bracts very thick, depressed and disk-like glands. More- 
over as only flowering branches are known of P. tatsienensis it is impossible to com- 
pare the flowers and fruits of these two forms.

The whole appearance of this plant, particularly the shape of the cupula and 
of the sepals agrees well with P. litigiosa Schneider. The differences in the floral 
parts might be explained by the fact that the flowers of the specimens before me 
are just beginning to open; the pedicels, petals and stamens, therefore, may not 
have attained their full length.

This species is very similar to P. Sargentii Rehder, but differs in the smaller 
and apparently paler and thinner leaves, the frequent presence of pubescence on the 
petioles, in the peduncle (4-20 nun. long), the occasional pubescence of the pedicels, 
the very slender cupula (6.&-10 mm. long, in P, Sargentii 5.5-7 mm. long) and in 
the smaller and broader stone (6-8 mm. long, in P. Sargentii 9-10 mm. long). The 
very similar P. Conradinae Koehne has precocious flowers, leaves with 9-12 pairs 
of veins and a shorter cupula (4-5 mm. long).

At the request of Mr. Wilson I have named this species in compliment to Bertie 
Twyman, Esq., of the British Consular service in China, who was of very con- 
siderable assistance to Mr. Wilson during 1908. Further investigation is needed 
to determine whether P. ampla Koehne, which is known only in fruiting speci- 
mens and has equally large glands on the teeth, belongs here.

This species is named for the daughter of the author. Henry's No. 5477 is the 
type of P. rufaidesy var. glahrifoUa Schneider, and does not di£fer in the least in 
foliage from Wilson's specimens; the pedicels of the fruits are in clusters of 1 to 4

(No. 45)- 

At the request of Mr. Wilson this species is named in compliment to Walter 
Reeves Zappey, who was associated with Wilson during 1907-1909 for the purpose 
of collecting Birds and Mammals. His whole collection of more than four thou- 
sand specimens has been presented by Mr. John E. Thayer to the Museum of 
Comparative Zoology of Harvard University. 

The fruits of the two Nos. seem to be somewhat different. In No. 70, too, the 
leaves are smaller (up to 4.2:4 m.) and in No. 45 larger (up to 8:35). From P. 
pleuroptera Koehne this species is distinguished particularly by the ovoid not glo- 
bular stones and by the midrib not being winged beneath. 

Here may be added two doubtful forms under the following name:

Western China: mountains, alt. 2800 m., May 1904 (Veitch Exped.

This plant, on account of the rather short and mostly simple serratures of the 
leaves, does not fit very well into the series Ceraseidos, but it resembles P. Zappey- 
ana so closely and the petals and stamens are, as usual in Ceraseidos, so small, that 
I cannot place No. 3526 elsewhere.

SUBGENERIS CERASI SYSTEM A NOVUM. 

This subgenus can be divided in two very natural groups: 

Grex I. TYPOCERASUS, Gemmae supra quamvis folii cicatricem solitariae, 
hae floriferae, illae ramum foliatum promittentes : plantae triaxiflorae. (Gemmae 
saepe in ramis abbreviatis confertae.) Petioli longiusculi v. longi. 

Ifj as usual, the branch of the previous year is considered as axis I., the a:ds of 
the bud or of the inflorescence will be axis II., exactly as in the subgenus PaduSf 
while the pedicel itself, even if the inflorescence is reduced to one flower, is to be 
called axis III. The plants therefore are tri-axial. 

In such a polymorphous group as Cerasus it is not surprising that transitional 
forms occiu". Thus I have observed in P. stipiUacea and P. microlepis occasional 
ternate buds after the type of Microcerasus. Both species, however, belong 
according to their other characters to Typocerasus, 

Grex II. MICROCERASUS. Gemmae sub florationis tempore typice ternae, 
media typice ramum foliatum promittens (saepissime vero abortiva), laterales 
floriferae; plantae quadraxiflorae. Petioli insigniter breves (exc. in P, pumikt 
affinisbusque, ubi petioli longiuscuU). 

The two lateral buds originate in the axils of the lowest pair of scales of the 
middle bud, their axes, therefore, become axes of the third order, while the pedi- 
cels will be axes of the fourth order. The plants, therefore, are quadri-axial.

Western Hupeh: Pa-tung, April 28, 1900, E. H, Wilson (Veitch Exped. No.

This species is yet incompletely known, but it differs from those species of this 
group, the flowers of which are knowTi, in the scales which form at the base of the 
umbel an involucre persisting during anthesis, in the more turbinate shape of the 
cupula, and in the nearly sessile umbel. From P. polytricha Koehne it dififers in its 
glabrous pedicels, and from P. clarofolia Schneider it differs apparently in the more 
acute teeth of the leaves. Prunus litigiosa Schneider, in which the involucre also 
persists, has much narrower petals. 

22. Prunus litigiosa Schneider in Fedde, Rep. Nov. Sp. I. 65 (1905). 
Hupeh: A. Henry (No. 5295). 

From those species of this group whose flowers are known P. litigiosa is pro- 
visorily well distinguished by the narrow acutish petals and the somewhat slenderer 
calyx. To form a correct opinion of this plant, much more copious material and 
particularly the fruits are needed.

23. Prunus clarofolia Schneider in Fedde, Rep. Nov. Sp. I. 67 (1905). 
Szech'uan: Nan-ch'uan, summer 1891, A. von Rosthom. 

The roundish form of the leaves and their pale color on both sides, as well as 
the slight lustre of the lower surface and the elevated veins and veinlets on the 
upper surface are very characteristic. Occasionally I have noticed the pale color 
and the lustre on the lower surface of the mature leaves also in other species of 
the group, but the prominent reticulation does not seem to occur in other species, 
nor the comparatively short and broad, not very acute serratures. It is to be 
hoped that the flowers will show, when they become known, that P. darofolia 
really belongs in the subsect. Pkyllocerasus.

The leaves are so characteristic and so different from those of all other cherries 
that it seemed advisable not to leave this species imdescribed, though neither the 
flowers nor the fruits are known. It is not impossible, however, that it belongs to 
P. scopulorum Koehne, known only in the flowering state. It should be compared 
also with P. Twymaniana Koehne of the sect. Pseudocerasus, which has equally large 
glands on the serratures and is known only in the flowering state.

^ Koidzumi considers P. pseudocerasus Lindley an entirely different species for 
the following reason: ^'P. pseudocerasus Lindley (non aliquot author. Europ. Amer. 
et Japonica) proved to be the Chinese Yung-to, and a species of the section Eupera' 
sus from the illustration by Dr. Hayata, which is delineated from Lindley^s original 
specimen in the herbarium of the Cambridge University." The following particu- 
lars of his description are especially important: Younger leaves on the petiole and 
on the vems beneath pilose or puberulent, glabrous above, doubly serrate. Flowers 
white; the corymbose racemes 4-o-flowered, pubescent, long or short peduncled; 
cupula broadly obconical, sepals ovate-elliptic, during anthesis horizontally spread- 
ing; style glabrous. Chinese name Yung-to. Central China, cultivated in Japan. 

I have not yet seen a plant which agrees with this description. Prunus pseu- 
docerasus Koidzumi certainly does not belong to the sect. Eucerasu^, which is not 
represented in China. If Koidzumi is right, it seems difficult to explain why Lindley 
should have quoted plate 800 of the Botanical Register as a figure of his P. Pseudo- 
cerasus, for this plate certainly represents the plant which all later authors have 
called P. pseudocerasus and which I place here. Concerning the Chinese name 
Yung-to, it belongs, according to Lindley, not only to his P. pseudocerasus, but 
also to his P. serrulata; according to Wilson, the name Yung-to (Ying-to) is ap- 
plied to every Cherry, while Ku-ying-to (bitter cherry) is applied to the species of 
the sect. Padus.

but I have not yet succeeded in finding out where to place it. It seems equally 
impossible to place or to refer to any other known species, Prunus pseudocerasu^, 
yar. jamasakura, f. pubescens Makino in Tokyo Bot. Mag. XXII. 98 (1908) - P. 
jamasakura, a elegans, b pubescens Koidzumi in Tokyo Bot. Mag. XXV. 185 (1911). 
The words "petiole spreadingly pubescent, pedicels spreadingly pubescent, calyx 
nearly glabrous" would lead me to think of P. paracerasus Koehne if it were not 
lor ^'common peduncle short or very so" and "leaves sparsely pubescent on both 
fiides." In P. paracerasus Koehne the peduncles are long and the leaves glabrous 
above. Of the pubescence of the style nothing is said by Makino. .

In collections P. serrulata is very often confused with P. Sargentii Rehder and less

to have been introduced in 1822 from China according to Lindley, but I have seen 
no specimens from China. Chinese locahties for it are sometunes given, but always 
with the quotation of synonyms which show a confusion between P. pseudocerasus 
Lindley and P. serrulata Lindley, so that these indications can not be safely used.

I have not yet seen specimens from China. Later, probably, several forms will 
have to be distinguished. In flower the living plant is markedly different from 
P. serrulata Lindley, but it is often difficult to refer dried specimens to the one 
or the other species. Very closely allied to P. Sargentii Rehder is P. tenuijlora 
Koehne, the range of which, however, is so widely separated from that of P. Sar-* 
gentii, that it seems better to consider P. tenuijlora for the present as a distinct 
species.

I do not know of which species this plant could possibly be a variety. Therefore 
I have considered it as a distinct species. 

At the request of Mr. Wilson this species has been named in compliment to 
Monsieur Wilden of the French Consular service in China, stationed at Chengtu 
in 1908, who rendered Wilson valuable assistance.

Nippon: Swasima, April 2, 1879, J. Maisumura (kindly sent to me by Professor 
Matsmnura, under the name oi P. pseudocerasusj /3 spontanea). 

The species can be distinguished from P. psetidocerasus Lindley by the glabrous 
under side of the leaves, and from P. serrulata Lindley and P. Sargentii Rehder 
by the pubescent upper side of the leaves. As I do not know to which of these two 
species it could be referred as a variety, I consider it necessary to give it provisorily 
a specific name. From P, parvifolia Koehne it is distinguished by the quite different 
shape of the leaves.

Japan: Sterile twig, F. van Siebold (in the Rijks-Herbarium, Leyden, as Cerasus

Cultivated in the Botanic Garden of the Agricultural College of the Imperial 
University of Tokyo, April 1908, Koidzumi (kindly sent to me by Matsumura as 
P^ pseudocerasus parvifolia Matsmnura and as P. pseudocerasus typica parvifolia 
Matsumura); from the same garden, a sterile twig, without date or collector; a 
sterile twig, June 22, 1901, Kamaba. 

Matsxmaura gives as the Japanese name Jugatsu-sakura, i. e. October-Cherry; 
he also states that the plant flowers in October. It is therefore strange that 
the flowering branches communicated to me are dated April. The species is very 
different from P. pseudocerasus Lindley. It might possibly be placed with P. 
Berrulata Lindley or ^ith P. Sargentii Rehder, but it differs so much from both 
that I must consider it a distinct species.

In the type the shoots are hirsute only toward the apex; the leaves are oblong or 
oblong-lanceolate, usually 6-9, or even to 14 cm. long and 2.5-4(-5) cm. broad, 
pubescent on the midrib above and sometimes also on the lateral veins; the sepals 
are 3-4 mm. long; the fruit in the fresh state is 9 mm. in diameter. The petals of 
the type are two-lobed as in the variety.

The examination of all the specimens in the Rijks-Herbarium at Leyden designated 
by Miquel himself as P. subhirtella has given the following result: there are four 
flowering and five leafy branches of the plant figured later by Hooker as P. sub- 
hirtellaj one flowering and one leafy branch of P. Herincquiana Lavalloe and four 
leafy branches of P. pendula Maximowicz. The variety oblongifolia Miquel con- 
sists of six flowering branches of typical P. subhirtella and four leafy branches of 
P. Bv^rgeriana Miquel. Therefore there can be no doubt that Miquel intended 
the name P. subhirtella for the same plant which later Hooker considered P. sub- 
hirtella, but that he added to his P. subhirtella by mistake wrongly determined 
branches of other species. I therefore think that the name P. subhirtella with 
the authority of Miquel can be retained for the species in question. Although 
Maximowicz refers P. subhirtella as a synonym to P. incisa Thunberg, no reason for 
this is apparent, as none of Miquel's specimens belongs to P. incisa. 

Japan : I have seen quite a number of specunens without locality or collector, 
also specimens collected by Siebold, Buerger and, as far as I could make it out, by 
Sahsabro (Miquel gives Saksako as the Japanese name of the plant). Further-

In the Herbarium at Leyden I have seen a branch with double flowers belonging 
to P. subhirtella. It was origmally labeUed Cerasus iiosakura flore semiplem), and 
then determined by Miquel as P. subhirtella. The number of petals was^ 13-14, 
about 11 mm. long and 7 mm. broad, the number of stamens 61 and of pistils 2. 
The style was glabrous; it is also in typical P. subhirtella sometimes nearly glabrous. 
Makino describes the stvle of his var. fukubana as "thinly pilose."

I have seen no specimen of this species. In the Berhn Botanic Garden a plant 
is cultivated received from Sapporo aus P. kurilensis which has not yet flowered. 
It exhibits the following characters : 

Rami hornotini autumno glabri, hinc pallidi, hinc purpureo-fusci, vetustiores 
nigres centi-f us ci ; gemmae 1.5-2 mm. longae, rotundatae v. ovatae. Stipulae circa 
3-4 mm. longae, ovatae vel oblongae, glanduloso-serratae, pro parte persistentes; 
petioli 5-14 mm. longi, breviter patentim viUosi; glandulae saepe 1-2, petioli apici 
vel laminae basi insertae; lamina e basi acuta vel rotundata rotundato-ovata v.

subacuminatis, glandula capitata terminatis, supra sparsim strigosa vel glabrata, 
subtus in coata, vix in nervis hirsuta v. glabrata, supra laete viridis, subtus 
pauUo pallidior. 

The leaves resemble strongly those of P. nipponica Maximowicz. The Berlin 
plant differs from the original description in the narrower leaves, which are described 
by Miyabe as orbicular to obovate, 7-8 cm. long and 5.2-6 cm. broad.

There are no indications in the Rijks-Herbarium at Leyden that P. incisa Miquel 

belongs here in part, as Maximowicz beheved. Prunus Miqueliana is apparently 

very near P. Tschonoskii, but differs in the very shght pubescence of the calyx 

and of the much shorter pedicels, in the shorter cupula and more numerous (34) 
stamens.

For a century this species has been always confused with P. japonica Thunberg, 
but it is very distinct and not connected with the latter by any intermediate forms. 
The opinion that transitions between these species existed arose from the fact that 
in herbaria admixtures of P. hiflora Koehne and even of Spiraea prunifolia Siebold 
& Zuccarini often occur without being recognized, and the characteristic shape of 
the leaves has thus been obscured.

Prunus Nakaii differs from P. japonica gracHlima Engleri in the much longer and 
niore numerous hairs which cover the leaves beneath on the midrib and on the 
Veins and less densely on the whole surface. As the flowers are not yet known, 
It seems better to retain P. Nakaii as a distinct species. The fruits had been 
described as hau-y but the hairs turned out to be particles of cotton sticking to the 
fruits.

This apeciea reaembles very much P. Nakaii L^veill^ and P. japonica gracillima 
Koehne in the shape and serration of the leaves, but is readily distinguished by the 
dense hirsute pubescence of the branchlets, petioles and leaves, and by the deeply

* It seems impossible at present to separate the following species by the shape 
and pubescence of the leaves. In young plants of Prunus sUnrica^ P. Armeni- 
<^a and P. mume the leaves are much more densely pubescent than in older 
plants in which the pubescence more or less disappears. The pedicels, the 
cupula and the sepals, too, in the species were both glabrous or pubescent, and I 
have not found it possible to determine the species of the section Armeniaca by the 
leaves and flowers alone. Fruits and stones onlv furnish reliable characters.

This species differs from Prunus triflora Roxburgh in the conduplicate leaves, 
scarcely, partly, or only slightly involute on the margin, the entirely glandlesa 
serratures of the leaves, the very short pedicels, and in the smaller flowers. The 
fact that in the Plums conduplicate as well as convolute leaves occur is more and 
more confirmed,

This variety differs except in its pubescence very little from the typical Prunua

tional forms seem to be: P. Masu Hort.^ ex Zabel in Beissner, Schelle & Zabel,

Japan, Buerger, 

This variety I have named in compliment to Professor Goethart, who has kindly 
sent me valuable material from the Rijks-Her barium at Leyden. A form of Prunus 
mume with completely pubescent cupula and pubescent sepala has not been 
described before. 

I hope that the flowering and the leaf bearing branches belong together. This, 
however, is not always the case in the older collections from Japan.

Armeniaca Davidiana Carri^re in Rev. Hart. 1879, 236, fig. 46-48, seems to be 
closely related to P. sibirica on account of the dehiscent epicarp and the smooth 
stone, characters which Maximowicz emphasizes for P. sibirica. He attributes to 
the latter "ramos patentes," while Armeniaca Davidiana has pendulous branches; 
it is therefore possibly a pendulous form of P. sibirica, Carri^re gives very gener- 
ally China as the habitat of his Armeniaca Davidiana; if it should have come 
from northern China, its range would be close to that of P. sibirica, which is 
found in southeastern Mongolia and in Dahuria.

According to the observations which I have made on young cultivated plants 
of the species of the section Armeniaca it seems hardly advisable to distinguish 
varieties by the pubescence of the leaves (see footnote, p. 279).

This is the Tung-ching (Winter-green) of the Chinese and one of the handsomest 
of their evergreen trees. It is commonly found planted over shrines and tombs. 
The tree reaches a height of 20 m. and is more or less spiny particularly while 
young and on the short inner branches. Photographs of this tree will be found 
under Nos. 2, 12, 472, 533, 627 and 0164 of Wilson's photographs and also in his

The plant collected by Piasezkii in Shensi and referred by Maximowicz according 
to Hemaley in Jour. Linn, Soc. XXIII. 57 (1886) to Xylosma senticosum Hance is more 
probably Xylosma racemosum, var. puhescenSj since it is unlikely that a subtropical 
plant would be found so far north. Both agree in having pubescent branches, but 
the leaves in Hance's plant are described as only 6-8 lines long. 

Xylosma Dunnianum L6veill4 in Fedde, Rep. Nov. Sp. IX. 455 (1911) apparently 
belongs to some other genus since he describes petals and says they are "twice as 
long as the sepals."

This handsome tree ia very rare in western Hupeh, but common in western 
Szech'uan, especially by the side of woodland streams up to 1200 m. altitude. 
Whilst not forming a tall or even large tree, the much-branched and flat head is 
wide^preading ; the bark is grey and usually smooth, but in very old trees it 
becomes furrowed and corrugated. The flowers are ivory-white and of much 
substance. 

A second species of this genus, Carrierea Dunniana L6veill€, is described in Fedde, 
Rep, Nov. Sp. IX. 459 (1911), but we have seen no specimens and the description is 
too meagre.

The Kiangsi and Hupeh plants differ from the type in the somewhat thinner 
and sometimes subcordate leaves. In addition to the characters given by Franchet, 
this species may be distinguished from S, praecox Siebold & Zuccarini by the 
broader and crenately serrate leaves, abruptly contracted into a long acumen, 
by the greenish or dull brown color of the one year old branchlets, and by the smaller 
fruits, while in S, praecox the serratures of the generally oblong-ovate leaves are 
more flaring and the one-year old branchleta are chestnut brown and lustrous. I 
have not been able to find among the Chinese specimens any representing the true 
S* praecoXf and I believe that all the Chinese specimens referred to that species 
belong to S, chinensis or possibly to S, himalaicua.

Stackyurus himalaicus is easily distinguished from the preceding species by the 
narrower, oblong or oblong-lanceolate, finely serrate leaves and by the smaller flowers 
with the style scarcely exceeding the petals. No. 2913 differs from the type in its 
broader less finely serrate leaves, and No. 10138* in its subi>er8istent leaves, the 
flowering branches holding still part of the leaves.

STYRAX L. 

Styrax dasyanthus Perkins in Bot. Jakrb. XXXI. 485 (1902); in

No. 4066; 4 m. high). 

No. 2572 differs from the type in having the lower suiface of the larger and broader 
leaves sparingly furnished with small fascicled hairs, and forms thus a transition 
to the following variety. In No. 4066 the leaves are broader and thinner and less 
closely veined than in the type and the inflorescence ia looser.

In general appearance, in the flowers and in the shape and venation of the loaves 
this variety agrees exactly with the type and therefore I cannot consider it anything 
else but a variety of S. dasyanthus.

I refer not without hesitation Wilson's No. 1733, which has only young fruit, to 
this species of which I have not seen the type. It differs from the description in its 
denser tomentum, even the mature leaves being densely grayish or whitish tomen- 
tose beneath; otherwise the specimen resembles closely S. philadelphoides Perkins, 
to which it seems to bear the same relation that S, dasyanthits, var. cinerascens 
Rehder bears to typical S. dasyanthus Perkins.

With the material before me I am not able to separate the form of western China 
from that of the southeastern provinces; the inflorescence is panicled in both 
forms, though the plate accompanying the original description shows a few-flowered 
inflorescence. The western specimens, however, have generally somewhat narrower 
leaves more cuneate at the base.

No. 2578 differs from the type in the somewhat larger flowers and shorter racemes, 
also in the generally narrower leaves which are finely denticulate.

The flowers are white according to Wilson^s notes on the labels, though in the 
dried state they have a pinkish hue which also appears in specimens of other species. 
The bright orange-yellow color of the calyx and of the winter-buds seems to be 
characteristic of this species.

The Chinese form differs from the type in the generally larger and shorter petioled 
leaves and in the more spreading corolla lobes which give the flowers a star-like 
shape. Styrax seminalum (1901) Farges, quoted by Miss Perkins (1. c.) as a synonym, 
is not a name, but signifies sowing No. 1901 collected by Farges; seminatiun is 
the term employed by Vilmorin for all undetermined sowings or seed lots. 

A very distinct variety is the following:

Shantung: Lau-shan, August 1907, F. N. Meyer (^o. 277). 

Differs from the type in the densely stellate-pubescent calyx and in the obovate 
leaves long-acimiinate and at the base very gradually narrowed into the petiole.

This species seems to be nearest related to S, officinalis Linnaeus, which is easily 
distinguished by the obtuse and entire leaves, the larger subglobose fruit with usu- 
ally a large part of the style persistent and the homomorphous tomentum of the 
calyx.

A very distinct species apparently related to S. officinalis Linnaeus and more 
closely to the preceding species, but easily distinguished from all allied species by 
the small more or less dentate leaves, the smaller flowers and smaller fruits. Styrax 
Wilsonii is in cultivation, and three year old plants flower and fruit freely when 
hardly a foot high. It will be figured in the July number of the Botanical Magazine.

which I have not yet seen mature leaves, only in the larger inflorescence attaining 
13 cm. in length.

Hsien, Pan-lan-shan, woodlands, alt. 2000 m., November 1910 
(4304; bush 3-4 m. high). 

This species seems nearly related to S. reflexa Schneider, but differs in the long 
acuminate leaves, the denser and usually shorter, only nodding, not pendulous 
inflorescence, the pubescent calyx and the not verrucose fruit. 

Syringa verrucosa Schneider, n. sp.

This snecies seems to be nearlv allied to S. vunnanensis Franchet, of whicn

yunrumensis, but in that species the leaves are much paler, rather whitish beneath, 
and the inflorescence is finely pilose. S, verrucosa and S. yunnanensia require

Western Szech'uan: toward Sungpan, thickets, alt. 3600-4000 
m., August 1910 (No. 4569). 

Though the specimen is rather meagre, this form can be readily distinguished 
from S. Sweginzowii Koehne & Lingelsheim and from all the other species of this 
group by the extremely long lobes of the corolla.

This seems to be an extremely beautiful shrub, most nearly related to S. tomen- 
tella Franchet, but the dense pubescence of the branches and the very short petioled 
broad elliptic leaves distinguish S. Rekderiana at once from the allied species.

Wilson's specimens differ from typical S. tomentella Bureau & Franchet in their 
glabrous calyic and less hairy inflorescence, and approach in this respect S, Wilsonii 
Schneider, but are easily distinguished from that species by the pubescent lower 
surface of the leaves.

(Herb. Arnold Arboretum). 

This species is very closely allied to S. pvbesceiis Turczaninow, but differs in 
the longer tube of the corolla, the minutely but distinctly puberulous branches and 
in the different venation of the leaves. I am in doubt whether the anthers are violet 
as in jS. pubescens or rose as in S. Potaninii,

The native habitat of C. ovata is apparently central China, where Wilson found 
it common in the margins of woods and more especially in the open country of 
Hupeh. Until recently it was generally considered a native of Japan, where it was 
first discovered by Kaempfer and whence it was introduced into Europe in 1849, 
but we know now that it was brought about the beginning of the Christian era by 
priests of Buddha from China to Japan and there much planted around temples (cf. 
Sargent, Silva N. Am. VI. 84). I am not able to find any reliable character to 
distinguish C. Henryi Dode from the cultivated form of C ovala^

markings in throat); without locality, A. Henry. 

Catalpa Dvclauxii, originally based on specimens from Yunnan, and C. suichueneri' 
sis are considered by Dode as two distinct species, the first characterized by a corym- 
bose inflorescence and grouped therefore with C. ovata D. Don, and the second by a 
racemose inflorescence and grouped with C. Bungei C. A. Meyer. There are, 
however, no other differences between these two supposed species; the leaves and 
also the flowers are exactly alike and the infloresences differ only in this, that in C. 
sutchuenensis the branches of the 2-6-flowered inflorescences are all simple, while 
in C. Duclouxii the lower branches of the 6-16-flowered inflorescences bear 2 or 3 
flowers, but one kind of inflorescence merges gradually into the other. No. 640 
from Ching-chi Hsien and No. 4289 have the many-flowered inflorescence of typi- 
cal C. Duclmxii, while No. 640 from Fang Hsien have all the lateral axes of the 
inflorescence simple; the other numbers are more or leas intermediate. It is jwssible

even to go farther and consider C. Dudouxii only a glabrous variety of C. Fargedi 
Bureau, which agrees with it in ahnoat every character except in the pubescence 
and perhaps in the somewhat stouter capsules. 

A photograph of this tree will be found under No. 0192 of Wilson's photographs.

A, Henry (No. 5856^). 

Catalpa Fargesii shows considerable variation in the density of its pubescence; 
while No. 748 has the lower surface of the leaves densely yellowish tomentose. 
No. 636 is only pubescent and No. 5856* is only slightly pubescent on the under 
side of the leaves and forms a transition to the preceding species. A closely related 
species or possibly only a variety is C. vestita Dials, which differs in its smaller 
flowers and smaller leaves whitish tomentose beneath. Seeds of this species col- 
lected by Wilson have been distributed erroneously under the name of C. vestita, 
while those of C. Duclouxii have been sent out as C. Fargesii.

This speciea is most closely related to S, Wightiana Wallich, which is easily dis- 
tinguished by the ovoid fruits, the trigonous oblong-ovoid, rugose seeds, scarcely 
1 mm. in diameter, and by the larger leaflets. In the smooth roundish light-colored 
seeds 5. Sckweriniana differs from all the other allied species. 

The two preceding Sambucus belong to a group of apparently much confused 
epeciea. As the conclusions I arrived at after a study of copious material differ in 
several respects from the treatment of these species by other writers, I add here a 
complete account of the three other species of this group with remarks on their rela- 
tionship and affinities.

(Elmer) J Java (Horsfield), , . 

This is a very widely distributed species ranging from the Malayan Archipelago 
to central Japan and western China and has also been found in eastern Africa. It 
is characterized by the slender pedicelled flowers, the presence of conspicuous 
abortive flowers and the very wide and loose inflorescence with the longer rays sub- 
thyrsoid; like the two preceding species it has red fruits and shows the tendency 
to have the upper leaflets more or less adnate to the rhachis and sometimes de- 
current. The Chinese form is usually quite glabrous and certainly has red fruits, 
as the specimens with ripe fruits show and as it is stated by Hance; the form of the 
Philippine Islands and of Java has usually a puberulous inflorescence and the leaves 
generally more or less pubescent on the veins; its fruit is described by Miquel and 
Hasskarl as greenish, by Junghuhn as yellow. In all other characters, however, 
the two forms agree perfectly and it does not seem possible to separate them spe- 
cifically. 

The two following species, which are not represented in the Wilson collection, 
occur in the Himalayas, and one of them also in China.

differs chiefly in the pubescent inflorescence with the rays subtended by leaves or 
bracts. From S. javanica it is easily distinguished by the absence of the aborted 
flowers and the smaller and denser pubescent inflorescence. Sambucus adnata has 
also been reported from eastern Africa, but its occurrence there ia not at all prob- 
able; very likely specimens of S. javanica with partly adnate leaflets have been 
erroneously determined as S. adnata,

is black; even if the color of the fruit should be incorrectly stated, the other 
characters are sufficient to separate it from S. javanica. 

All the species enumerated above form a group of closely related species charac- 
terized by the valvate aestivation of the corolla, the suffruticose stems and the ten- 
dency of the upper leaflets to be adnate to the rachis. On account of the aestivation 
of the corolla and of the suffruticose habit they are best referred to the section 
EhuluSj though they differ from the type of this section in their spreading stamens 
with yellow anthers, smaller flowers and smaller fruits red or yellowish, except in 
S, Hookerij which is described as black-fruited. On the presence of abortive flowera 
in one of the species Miquel based his section Scyphidantke, which was erroneously 
placed by Fritsch and by Schwerin as a subsection in the section Eusambucus 
in which the aestivation of the corolla is imbricate, I agree with Hancc that the 
presence of abortive flowers is hardly a sufficient character upon which to base a 
section, and Scyphidantke therefore should be merged into the section Ehulus, 
Of the six species of this section S. Ebulus L. stands quite by itself on account of 
its larger flowers, upright stamens with violet anthers and of its rather large purplish- 
black fruits and always distinct leaflets. A second group is formed by S. WightU 
ana, S. Schweriniana and S. adnata, similar in habit to S. Ebulus, but differing 
in the smaller flowers, spreading stamens with yellow anthers, red fruits (finally 
black in S. Wightiana) and usually adnate upper leaflets. The third group com- 
prises S. javanica and S. Hookeri and is characterized by the presence of abortive 
flowers and by the very wide and loose inflorescence with the rays partly sub- 
thyrsoid, while in its other characters this group is nearest to the second group.

Henry's specimens present apparently the normal development of the inflores- 
cence, which is borne on very short spurs lateral on two year old branches, without 
any leaves at the base, and only with caducous scales. The very loose and lax appar- 
ently pendulous inflorescence is, including the 1.5-7 cm. long peduncle, 10-22 cm. 
long and 10-15 cm. wide; the name V. brachybotryum therefore seems very inap- 
propriate for this species, which has one of the largest inflorescences in the whole 
genus. It is highly interesting .that Henry's specimens show conclusively that 
V. brachybotryum has indeed dioecious flowers; Nos. 10065 and 12700 represent the 
pistillate and Nos. 10065a and 12790a the staminate plant. In the pistillate flowera 
the corolla-lobes are spreading as they are in the staminate flower, and also in the 
shape of the inflorescence the two sexes are alike except that the staminate inflores- 
cence ia generaUy somewhat larger and laxer.

Callicarpa vaatifolia Diels in BoL Jahrh. XXIX, 547 (1900). 

Callicarpa vastifoliaf based upon branches without flowers or fruits, is nothing but 
V. rhytidophyllum. The fohage agrees exactly and even the bud of the inflorescence 
for the following year can be discerned between the terminal pair of leaves, while 
in Callicarpa the corymbs are axillary and their buds are not formed the year 
before.

The flowering specimens of F. brevipes had been misplaced and were found after 
the description drawn up from the fruiting specimens had been published. The 
leaves of the flowering specimen differ slightly in being generally rhombic-elliptic 
and only 4r-5 cm. long, also the glands on the lower surface of the leaves are not 
as copious. Wilson's No. 944, referred provisionally to this species, does not belong 
here, but is very near F. dilatatum Thimberg and probably referable to that species. 

I take the opportunity to add here the descriptions of two new Chinese species 
and a new variety.

CAPRIFOLIACEAE — LEYCESTERIA 311 

Viburnum calvum seems most nearly related to V. jmndatum Don, which is 
easily distinguished by the larger acuminate leaves lepidote below and by the 
sessile or subsessile much larger and lepidote inflorescence.

Though neither the corolla nor the ripe fruit of this plant are known, there can 
be no doubt that it is a distinct and well marked species. There are only few species 
with lateral inflorescences and from all of them V. laterale is easily distinguished 
by its glabrousness; it seems nearest to V. amplifolium Rehder, which differs be- 
sides in its pubescence, in the larger corymbs and in the longer and cylindric style. 
Viburnum Colebrookianum Wallich, which is sometimes nearly glabrous, is easily 
distinguished by its oblong and longer leaves and by the corymbs being borne on 
leafless branchlets.

Exped. No. 3719; bush 1 m., flowers white). 

The typical form has not yet been found in Szech'uan; it differs from this variety 
in its shorter triangular-ovate to lanceolate sepals, larger and usually purplish and 
glabrescent bracts and in the leaves being glaucescent on their lower surface and 
usually rounded or even subcordate at the base. The Yunnan specimens of the 
type have all the sepals very short, scarcely exceeding 1 mm., while the Himalayan 
specimens have usually at least two of the sepals elongated. 

Besides L. formosa two other species occur in Yunnan: L. glaucopkylla Hooker f., 
of which I have seen Henry's No. 9767, and L. chinensis Hemsley.

Thi3 small tree is abundant in the thickets and margins of woods, especially in 
the vicinity of streams throughout western Szech'uan from the neighborhood of 
Sung-pan in the north to Tachien-Iu in the west and southwards through Yunnan. 
We have no specimens actually localized from Mupin, but have them from the 
northern, southern and western boundary of this petty state. We have not seen 
the type of Baillon's E. Davidiana^ but the geographical distribution so strongly 
supports Solereder's evidence that there can be no doubt but BaiIlon*s fragment 
is referable to the same species and to its numerous specimens before us. 

Hooker & Thomson describe the under surface of the leaves as " pale," but 
glaucescent gives a better idea of the appearance, which is due to a dense cover- 
ing of papillae. This glaucescent appearance of the under surface readily dis- 
tinguishes this species which, like E. Franchetiif is a small bushy tree, with thin 
branches and leaves asaiuning brilliant tints in the autumn. 

Our specimen of Henry^s 10746 has all the leaves ovate, acuminate and broadly

As pointed out by Hemsley (1. c.) the particular characters on which Van Tieg- 
hem founded this species are not constant and are of little value. The overlooked 
character of the green under-surface of the leaves, with perfectly smooth non- 
papillose epidermis is, however, constant and affords a means by which this species 
may be distinguished at a glance. Specimens before us prove that the relative 
length of the filament and anther is merely a question of age and growth, as enun- 
ciated first by Hemsley, whose figure (I. c.) admirably depicts this species but 
whose description in part includes the western species E. pleiosperma, Hooker & 
Thomson. 

E. Franchetii is one of the most common of small trees throughout western 
Hupeh and eastern Szech'uan, occurring by the sides of streams, on the margins 
of moist woods and thickets. 

The species of this genus have proved very difficult to deal with systematically 
and various authorities have arrived at different conclusions in regard to them. 
With the mass of material before us we are convinced that in China two species, 
each occupying well-defined geographical areas, occur. The shape and size of the 
leaves and degree of their dentation, the relative length of the filaments and 



TROCHODENDEACEAE. — ETJPTELEA 315 

anthers, the size and shape of the fruit and the number of seeds in each are all 
inconstant and cannot be relied upon. Finet & Gagnepain (1. c.) give a key to 
the species based on the shape of the fruit. Specimens before us show all forms 
on the same branch. The appearance of the under surface of the leaves, how- 
ever, affords a constant character by which the species, and especially the two 
Chinese species, may easily be recognized. Solereder (1. c.) was the first to draw 
attention to this and an exhaustive examination of our materia! amply sup- 
ports his conclusions as to the identity of Baillon's E, Davidiana with Hooker & 
Thomson's E. pleiosperma. 

The three species of the genus may be recognized by the following charac- 
ters : — 

E. polyandra Siebold & Zuccarini: bark brown; dentation of leaves irregular 
and more exaggerated in this respect than in other species; under surface of leaves 
pale green and exhibiting a tendency towards papillosity; fruit normally 1-seeded 
although 2 seeds are occasionally to be found. Distribution: Japan. 

E. Franchetii Van Tieghem; bark dark; dentation of leaves fairly regular; 
under surface of leaves green; non-papillose, the epidermis being perfectly smooth; 
fruit 1-4 (usually 2-3)-seeded. Distribution: central China. 

E, pleiosperma Hooker & Thomson: bark dark; dentation of leaves fairly 
regular; under surface of leaves glaucescent, papillose; fruits rather larger than in 
other species, 1-4 (usually 2-3)-seeded. Distribution: Mishmi Hills, north-east of 
Assam, western and south-western China. 

The flowers in all three species are hermaphrodite, proterandrous and ane- 
mophilous, not polygamous as usually stated. The stamens are early deciduous, 
falling away before the stigmas of the female flowers borne on the same fascicle or 
on the same shoot are mature. The statement that the trees are dioecious is 
erroneous and has led to much confusion.

We have seen no flowers of this variety, and in the herbarium material the 
characters which distinguish it from the tjrpe are rather slight. In habit the 
two trees are different. The Japanese tree has usually several trunks which, if occa- 
Bionally united at the base, diverge a few feet above the ground. Sometimes, 
however, the trunk is single and free of branches for 16 m. above the ground. 
The Chinese tree has usually but one trunk and lateral branches commence a 
few feet above the ground; occasionally a few small stems are found growing 
around the base of the tree. Very rarely are two or three trunks developed and 
we never saw more than half a dozen such examples among the thousands of trees

park-like areas or glades, always in moist situations where the soil is rich; a favor* 
ite site is alongside the mountain torrents. 

This Chinese tree is now in cultivation and, for the present at any rate, it would 
appear best to consider it as a variety distinct from the Japanese type. In time 
we may learn more from the cultivated trees of both forms and their taxonomic 
rank may then be more accurately determined. 

The Chinese Cercidiphyllum is abundant in the mountains of the Lungan pre- 
fecture, in north-western Szech'uan, and trees of huge dimensions occur. It is 
fairly common around the base of Wa-wu-shan in the Yachou prefecture, western 
Szech'uan. In the highlands of the Han-Yangtsze divide, in the districts of Hsing- 
shan and Fang, western Hupeh, it is also plentiful. Both in height and girth this 
tree exceeds all other broad-leaved deciduous trees known from China. It attains 
a great age and is very tenacious of life. Old, hollow stumps of trees, broken 
down by winds and partially destroyed by fire, still continue to develop green, 
leafy branches until utterly destroyed and up-rooted. Owing doubtless to some 
obscure resemblance in the foliage and general appearance of the two trees the 
Cercidiphylliim is colloquially known by the same name as the Ginkgo, viz. " Peh- 
k'o." Pictures of this tree will be found under No. 095, 096, 086, 0276 of 
Wilson's collection of photographs and also in his Vegetation of Western China, 
No. 163.

We have given a complete description of this variety which differs from the 
type chiefly in the narrower segments of its leaves, paler color of stamens and 
fewer carpels, because the original description of the type is rather short. 

Here may be added a note on the habitat of the Moutan, together with ita 
synonymy, which in most publications is incompletely and partly incorrectly 
quoted.

The specimens quoted above are according to Mr. Purdom from undoubtedly 
wild plants; he also introduced living plants of this wild form which are now grow- 
ing in several gardens. The habitat of P. suffruticosa has been for a long time 
uncertain, as all the earlier travelers in China had found it only in gardens. The 
first mention of its native habitat in north-western China we find in Engler & 
Prantl, Nat. Pflanzenfam. III. 2, 55 (1891) where Prantl states that it occurs in 
Kansu north of the Hoang-ho, without giving any authority for this statement. 
Bretschneider ( Hist. Europ. Discov. China, 425) says that according to a Chinese 
description of the province of Shensi the Moutan occurs in the district of Han- 
ch'eng on a hill called Moutan-shan. Between 1890-1896 it was collected by 
Hugh Scallan and G. Giraldi near Ki-san, Gniu-ju and Lun-shan in Shensi, and now 
with the added evidence of Purdom's collection there can be no doubt that P. 
sufrulicosa is a native of north-western China and was introduced from there into 
eastern China and into Japan.

Type in Manchuria and north-east China. 

Plants grown in this Arboretum from seeds collected south of Jehol by M 
Purdom seem indistinguishable from C. tubulosa Turczaninow which represents 
the type of the species, while all the other synonjmas are referable to the var. 
Davidiana Hemsley, These seeds came from the locality where Staunton collected 
the specimen on which C. heracleaefolia De Candolle is founded. From the mass 
of material before us we are disposed to refer all the continental forms of this 
group to C. heracleaefolia De Candolle and its varieties, considering them all 
variations of one polymorphic, polygamous species. The Japanese C. stans Siebold 
& Zuccarini (syn. C. Maximovnczii Decaisne, C. Lavallei Decaisne, C. Savatieri 
Decaisne) with its coarsely toothed and lobed leaves, loosely paniculate inflores- 
cence, small whitish flowers and glabrescent, shining, ovoid achenes, seems to us 
suflBciently distinct to be considered a species.

This variety is chiefly distinguished by its rather dense pubescence. The type 
agrees in the stems being woody at the base and the leaf-bases rounded, but 
differs in its more coarsely toothed glabrescent leaves, polygamo-dioecious flowers 
and sparsely villose achenes. Var. Davidiana differs in its herbaceous habit, 
cuneate leaves, glabrescent and coarsely toothed, and more sessile densely clus- 
tered inflorescence. In general appearance this new variety comes nearest to the 
form found in Shantung, which, however, has more coarsely toothed, less hairy 
leaves, usually cuneate at the base and unisexual flowers. The Shensi specimen 
collected by Giraldi is somewhat less pubescent than the other specimens.

An exceedingly common species throughout central and western China, grow- 
ing in thickets and margins of woods. The leaves vary considerably in size. The 
young shoots, more especially the nodes, and the flower-buds are viscid. The 
flowers vary in color from nearly white to dark red-purple. Maximowicz {Act, 
Hort, Peirop. XI. 7) was disposed to regard the Chinese plant as distinct from the 
Japanese. With the large series of specimens before us we can find no characters 
on which to separate them. The color of the flowers is variable even in the Japa- 
nese plant, and although the type has white flowers a specimen before us from 
Nanokawa, Tosa, Japan, has obviously pale red-purple flowers.

3120^, seed No. 1422); vicinity of Tachien-lu, A. E. Pratt (No. 592). 

In general appearance the foliage of this variety somewhat resembles that of 
C. Buchananiana De Candolle with which Finet & Gagnepain have confused it, 
but the leaves in that species are always simply pinnate and less deeply toothed. 
In our variety the sepals are about as long as the carpels (1.5-1.8 cm.) recurved 
at the apex and glabrous on the inside. In C. Buchananiana the sepals are 
nearly twice as long as the carpels (2-4 cm.) and densely pubescent on the inner 
surface . 

This variety is distinguished from the type by its broadly ovate leaflets, usually 
cordate at the base, silky pubescent below and with more prominent veins.^ The 
inflorescence too is larger and more compact. It is very common around Tachien-lu, 
rambling over shrubs in situations fully exposed to the sun.

Common in thickets and hedge-rows in the neighborhood of Tachien-lu, 

This species is very closely related to C. connata De Candolle, especially to the 

form latipes Kuntze, and would seem to differ from it chiefly in its more coarsely 

toothed leaves and shorter, more compact inflorescence.

The narrower leaflets, usually racemose, not paniculate inflorescence, acute 
sepals and fulvous awns to the carpels sufficiently distinguish this species from 
C. Meyeniana Walpers with which it has been confused in herbaria. We have 
seen no specimens from central or western China which could be referred to C. 
Meyeniana Walpers, and it is probable that this species is restricted to southern 
and sub-tropical parts of China. We suspect that many of the specimens referred 
to C. Meyeniana by Finet & Gagnepain {Contnb. Fl. As. Or. I. 15 (1905)), belong 
to C. Pavoliniana. 

C Pavolinian^i is very common in the glens and ravines round Ichang up to

This plant always dries black and at first sight suggests a large-flowered variety 
of Clematis chinensis Retzius. The leaves, however, are usually pinnately 7-folio- 
late, the basal pair being often trlfid or even trifoliolate. The leaflets vary con- 
siderably in size and shape and in depth of the incisions; the flowers are often 4 cm. 
across, with 5-8 sepals and are fragrant; the awns are fulvous-brown.

330 WILSON EXPEDITION TO CHINA 

This species has been much confused with that named by Hemsley C Sen- 
thamiana. The differences pointed out by Forbes (1. c.) seem to us sufficient to 
make the separation of these species possible. The Chinese name in Hupeh for 
this plant is Chin-lung-hsii.

This, like Clematis chinensis Retzius, is a low-level species very common all over 
the warmer parts of China. The' leaves are usually more coriaceous than those 
of C. chinensis. Forbes (1. c.) gives a good account of the differences between C. 
Benthamiana and C. chinensis, but makes the mistake of retaining the name C, 
ierniflora for the former. That name, however, belongs to C. recta, var. mandshurica 
Maximowicz, as Staunton's specimen which must be considered the type of De 
CandoUe's C. ierniflora represents C. recta, var. mandshurica, while C. Flammula 
var. of Linnaeus' herbarium, which is also quoted by De Candolle as a synonym 
of C. ierniflora and entered partly into his description belongs, according to Forbes, 
to C. chinensis. If, therefore, C. recta, var. mandshurica is raised to specific rank 
the name C ierniflora must replace C. mandshurica Ruprecht.

RANUNCULACEAE. — CLEMATIS 333 



This variable species is abundant on the mountains of central and western 
China. Of the specimens we have referred to the typical form that from Szech'uan 
has small and often entire leaflets. The varieties ruhens Wilson and Wilsonii 
Sprague show a greater divergence from the type than any of the Himalayan 
specimens we have seen.

The foliage of this variety is very dark coloured and readily distinguishes the 
plant when out of flower. Aa Sprague {Bot. Mag, sub t. 8365) has pointed out, 
there is considerable doubt as to this Chinese plant being the same as the Indian 
plant to which Kuntze applied his name ruhens, basing it upon a statement of 
Hooker & Thomson. By the Chinese in Hupeh this plant is called Ta-huai-t'ung.

The relatively thick leaves densely covered with yellowish Bilky hairs, the 
sericeous flowers and particularly the densely pilose achenes readily distinguish 
this species from C. montana Buchanan-Hamilton and all its numerous varieties 
and forms. It appears to us more closely allied to C. ckrysocoma Franehet in which, 
however, the flowers are pink and produced on the shoots of the current season. 
The flowers of C. Spooneri are of much substance and very beautiful. The plant 
grows naturally in rocky places fully exposed to the sun and is very floriferous. 
The varietal name sericea appUed by Franehet to this plant cannot be used specif- 
cally as there is a C. sericea Humboldt, Bonpland & Kunth; there is also another 
American species of the same name, C. sericea Michaux.* 

In raising this plant to specific rank we have thought it advisable to draw up 
a complete description since the distinguishing characters given by Franehet are 
very brief.

This species differs from the other species of this group in the inflorescence 
which is reduced to one or three large flowers; it thus forms a transition to the 
preceding group, but the flowers, even when solitary, are always borne on dis- 
tinct peduncles in the axils of the leaves of young branches.

In addition to the characters mentioned by Franchet it seems to differ from the 
type in the often narrower leaflets broadly cuneate at the base and glabrescent 
beneath.

species.

The broader and larger, more pubescent leaflets usually truncate or subcordate 
at the base, less deeply incised, with obtuse and brt)ader teeth generally distin- 
guish this variety from the type. The specimens before us strongly suggest that 
they belong to C. grata Wallich, but we have referred them to C. apiifolia D. C, 
chiefly on account of their 3-foIiolate leaves. The Vitalba group is extremely 
puzzling and none of the species have clearly defined limits. 

No. 1233* has the under surface of the leaves densely clothed with soft, gray 
villose pubescence.

This is a fairly common low-level plant i;i western Hupeh being usually found 
in stony places by the side of streams or roads fully exposed to the sun. It differs 
from W^Uch's figure in its more acuminate, often trifid or sometimes 3-foIiolate 
leaflets, with fewer, much coarser teeth. From C. grata^ var. grandideniatu Rehder 
& Wilson it is readily distinguished by its smaller, often trifid or 3-foliolate, more 
acuminate leaflets, usually b~Q cm. long and 3-5 cm. broad and generally cordate 
at the base, by the more numerous flowered cymes and small, green, leaf-like 
bracts. It is also a more hairy and much less ornamental plant.

This rather variable species is widely distributed in China and is very abundant 
throughout the warmer parts of the Empire. The flowers are small, borne in 
very large axillary and terminal panicles. The leaves vary considerably in size 
and are either glabrous or puberulous, entire or more or less toothed. In No. 1229 
the leaves are more coarsely toothed than usual.

This species is widely distributed and is most polymorphic in character. The 
varieties described by us are strikingly distinct from the type, yet we cannot sepa- 
rate them specifically. The Hupeh material referred to the type differs from a 
specimen collected at Peking (Herb. Hance, No. 12703) in having more slender 
stamens with larger anthers, and darker colored plumes to the achenes. We are 
disposed to regard the Japanese C. Pierotii Miquel as a variety of this species. 
We strongly suspect, too, that some of the specimens referred by Finet & Gagne- 
pain to C. parvilobay var. glabrescens really belong to C. hrevicavdata.

This is a vigorous growing plant distinguished from the type chiefly by its 
glabrous achenes and larger leaflets. It is more closely allied to the variety suh" 
sericea Rehder & Wilson which has much smaller, pinnate leaves pubescent below, 
the inflorescence less than half the length of the leaves and without leafy bracts. 
Henry's specimen differs in having coarsely toothed leaves sparsely pubescent 
below and in these characters closely resembles the typical C. hrevicavdaia but in 
its glabrous achenes and other respects it agrees closely with this variety.

342 WILSON EXPEDITION TO CHINA 

A distinct variety in some respects intermediate between var. tenuisepala 
Maximowicz and var. Ussocarpa Rehder & Wilson having the narrow sepals and 
villose achenes of the former and the glabrous character of the latter. From both of 
these and from other forms of this variable species it is distinguished by the charac- 
ters described above. Though the leaves are thin in a dried state we suspect that 
they are rather fleshy on Uving plants. In foliage it resembles somewhat C. chinensis 
Retzi;^, which is easily distinguished, however, by its linear-oblong anthers 
short filaments, pointed buds, paniculate inflorescence and firmer, usually narrower 
leaflets, drying nearly black.

The type does not seem to occur in western China. 

The plant from the Pamirs which Korshinsky describes as C tangutica (Maxim.) 
is apparently not Maximowicz's plant, but belongs probably to the true C. orientalis 
Linnaeus. Korshinsky describes his plant as having " sepala ovata, acuta, intus 
pubescentia . . . flores 3^ cm. in diamatro," while Maximowicz's plant has 
acuminate sepals, glabrous inside and flowers about 7 cm. in diameter. From the 
following variety the plant from the Pamirs is easily distinguished by its sepals 
being pubescent on the inside.

In its smaller and more sparingly serrate leaflets and in the shorter, obtusish 
or acutish sepals this variety differs chiefly from the type which has the sepals 
long-acuminate and up to 3.5 cm. in length. The plant figured in Rev. Hort. 
agrees in the obtuse sepals with this variety, but they are described as 3-4 cm. 
long; specimens of cultivated plants before us have the sepals long-acuminate, as 
described by Maximowicz. A picture of this plant will be found under No. 0290 
of Wilson's collection of photographs.

LARDIZABALACEAE. — HOLBOELLIA 345 



Our specimen, which is male, differs from Gagnepain's description in its shorter 
(1-2.5 cm. long) petiolules, longer (2.5-5 cm. long) pedicels and in the cuspidate 
rather than uncinate leaves. In all essential characters, however, it agrees exactly 
and we have no hesitation in referring it to Gagnepain's species. Stauntonia 
Duclouxii is a handsome climber with large, fragrant and abundant .flowers. It ia 
apparently very rare in Hupeh, as we met with one plant only. 

Stauntonia sp. no v.? 

Western Szech'uan: Hung-ya Hsien, base of Wa-wu-shan, 
thickets, alt. 1300 m., September 1908 (No. 894). 

This is distinct from any species known to us. It seems nearest, however, to 
S. Duclouxii Gagnepain, from which it differs chiefly in its 4-6-folioIate leaves and in 
the thinner leaflets usually obtuse and mucronate at the apex. Our material con- 
sists only of leaves and fruit and is too fragmentary to serve as the typ^ of a new 
species. 

F. Gagnepain in his elaborate paper (Revision des Lardizabal(5es asiatiques de 
THerbier du Museum {Bull. Mus. Nat. Hist Paris, XIV. 64-70 [1908]) discourses 
carefully on the classification of this family, and we agree with him in considering 
Stauntonia and Holbodlia distinct genera. The confluent filaments of the stamens 
in Stauntonia (with which we unite Parvatia) are concomitant with the relatively 
thin, acuminate sepals except in the case of S. filamentosa GrifiBth; the free fila- 
ments in Holboellia are concomitant with thick, fleshy, obtuse sepals. We agree 
with Hemsley (in Hooker^s Icon. XXIX. sub. t. 2843 (1907)) in uniting Decaisne^s 
Parvatia with Stauntonia De CandoUe. The presence of six nectaries in both male 
and female flowers in Parvatia and their presence in the female and absence in 
the male flowers in Stauntonia seems too sHght a character to base generic dis- 
tinction upon.

3-foUolate, more coriaceous, and less conspicuously veined leaves, by the longer 
peduncles and longer pedicels to the pistillate inflorescence, by filaments as long or 
slightly longer than the anthers and by smaller seeds. The undescribed fruit is

LARDIZABALACEAE. — AKEBIA 347 

This is the common Holboellia of the thickets and margins of woods throughout 
western Hupeh occurring at higher elevations than H. coriacea Diels. From the 
evidence of abundant material before us and our knowledge of the wild plants we 
are unable to agree with Gagnepain {Bull. Mus. Nat. Hist. PariSy XIV. 67) in 
referring this plant to H. latifolia Wallich or as a variety to that species. We have 
seen no specimen from central or western China referable to Holboellia angustifolia 
Wallich and apparently it does not occur there. The only specimens of H. lati- 
folia Wallich we have seen from China are Henry's Nos. 10527, 10527", both col- 
lected near Mengtze in Yunnan. We suspect that the Holboellia latifolia of Fran- 
chet {Nouv. Arch. Mus. Paris, ser. 2, VIII. 194 (PL Damd. II. 11)); of Diels (Bot 
Jahrh. XXIX. 343); of Pampanini {Nuov. Giorn. Bot. Ital n. ser. XVII. 273), and 
of Reaubourg {Bull. Sac. Bot. France^ LIII. 452) belong to H. Fargesii R^aubourg. 

Holboellia Fargesii is an extremely variable plant, and R6aubourg's description 
refers to one form of the species and to a shoot bearing male flowers only. Hem- 
sley's figure (1. c.) represents another form, and everj' gradation between these two 
extremes can be found. In the specimens before us the leaflets vary from 3 to 9 
in number, from 3.5 cm. to 12 cm. in length excluding the petiolule, and from 1 cm. 
to 4 cm. in width; the petioles ffom 2 cm. to 12 cm.; the peduncles with pedicels 
on male flowers from 2 cm. to 6 cm.; on the female flowers from 4 cm. to 15 cm. 
All these variations are to be found on the same individual and very often on the 
same shoot. The flower and its parts, however, are constant as described by 
Hemsley, except that the female flowers are almost invariably the larger. The fruit 
which has not been described is purple, oblong, 7-9 cm. long, rounded, tipped with 
a short point; the seeds somewhat verruculose, jet black, 4-5 mm. high, 5-8 mm. 
long. This species is undoubtedly closely related to H. angustifolia Wallich, which 
is readily distinguished by its relatively thin leaves with prominent reticulate 
venation, much shorter peduncles and pedicels, different shaped sepals and by a 
somewhat different floral structure.

This variety is much more abundant in central and western China than the 
type and is found at lower altitudes. Gagnepain (I. c.) refers this plant to A. 
clematifolia Siebold & Zuccarini and at the same time reduces it to a variety of 
A. lohata Decaisne. The plant of Siebold & Zuccarini is easily distinguished from 
A . lobataj var. australis Diels, by its thinner and much broader leaflets and is best 
kept as a distinct variety. 

Here may be added a note on a variety of A. quinata from Formosa:

Formosa: Takow, Ape's Hill, A. Henry (No. 319; large climber, in flower 
May 12); Bankinsing, A. Henry (No. 1829). 

This differs from the type only in its very much longer peduncles and usually 

broader leaflets.

LARDIZABALACEAE. — SARGENTODOXA 351 



Sargentodoxa resembles in its foliage so closely Sinofranchetiaj tliat Oliver de- 
scribed the flowers of this genus and the fruits of Sinofranchetia as belonging to the 
same species. The fruits, however, are so entirely different from all other members 
of the Lardizabalaceae^ that this new genus can only be retained in its present place, 
if the characters of the family are considerably amended, or it must be made the 
type of a new family, but as long as the pistillate flowers are not known, it may be 
safer to leave it with the Lardizahalaceae as an anomalous genus which has the 
number of ovules in each carpel reduced to one and the number of carpels multi- 
plied. Though we have not seen the pistillate flowers, we are convinced that aside 
from the sexual organs they do not present marked differences, as the inflorescences 
are exactly alike. The characters of the young carpels we described from unde- 
veloped carpels which we founcl on the torus of the fruit between the mature 
carpels; they also show that the young carpels are at first sessile and that the 
remarkable long stalk develops while the carpel grows to maturity.

The type of Franchet has the leaves distinctly glaucous beneath and also pruinose 
twigs. This is the same in B. approximata^ described by Sprague in Kew Bull, 
Misc. Inform. 1909, 256. Sprague cites the plate 7833 of the Bot. Mag. which 
represents only a form of B, dictyophylla with copiously serrate leaves. The flowers 
of the plate are as large as on plate 11 of Franchet in his PI. Delavay. Therefore 
I agree with Rehder in treating it as a variety of the type as B. dictyophyllaj var. 
approximata Rehder in Mitt. Deutsche Dendr. Ges. XX, 183 (1912).

Sungpan, thickets, alt. 3800-4000 m., October 1910 (No. 4190; bush, 
1.5-1.75 m. tall, fruit scarlet). — The following specimens possibly 
belong to this species: Pan-lan-shan, west of Kuan Hsien, alt. 4000- 
4300 m., June 24, 1908 (No. 2865; bush 0.60-1.30 m. high, flowers 
yellow); south-west of Tachien-lu, woodlands, alt. 3000-3600 m., 
October 1910 (No. 4170; bush 1.30-2 m. high, fruit crimson). 

There are three species which seem to be very nearly related; these are B, 
macrosepalaj B. diaphana and B. yunnanensis. The one described first is B. macro- 
sepala Hooker f. & Thomson, which comes from the Sikkim Himalaya. It is well 
distinguished by its puberulous branchlets and has not yet been found in China. 
Mr. Hutchinson says in BoL Mag. (I. c), that it has been collected in western China 
by Wilson, but this seems to be an error. He also describes and figures there as 
B. yunnanensis a cultivated plant, which certainly belongs to B. diaphana. The 
type of this species may be distinguished by its chartaceous leaves distinctly re- 
ticulate on both sides and mostly serrate, by the 1-4-flowered inflorescence, and 
by the more numerous, 6-8, ovules and seeds. The typical B. yunnanensis^ of which 
I have seen Franchet's type specimens, has thinner, mostly entire leaves and 3-8- 
flowered, often rather elongated inflorescences and only (3-)4 ovules and seeds. 
The nervation of the leaves of B. yunnanensis is coarser and thinner and nearly the 
same as in those of B. macrosepala, the leaves of which are more papillose beneath 
and more Serrate. The types of these three species may be distinguished as follows: 

Berheris macrosepala: ramuli puberuli; folia adulta membranacea, plerumque 
spinoso-serrata, utrinque laxe reticulata, subtus distincte papillosa; fiores ple- 
rumque solitarii; ovaria ovulia circiter 6 instructa; styli nulli. 

Berheris diaphana: ramuli glabri; folia adulta chartacea, plerumque spinoso- 
serrata, utrinque distincte et anguste reticulata, subtus pruinosa v. leviter papil- 
losa; flores soHtarii v. bini v. ad 4 racemoso-fasciculati; ovaria ovuhs 6-8 instructa; 
styli breves v. nulli. 

Berheris yunnanensis: ramuli glabri; folia adulta membranacea, plerumque 
Integra, utrinque laxe reticulata; flores 3-8 fasciculati v. fasciculato-racemosi v. 
racemosi; ovaria ovuhs (3-)4 instructa; styU breves v. nulli. 

But there are some forms, which I think are intermediate between the last two 

species, for instance, Wilson's No. 4170. The leaves of this specimen are mostly 

entire, their nervation is rather hke that of B. diaphana and the fruits are solitary, 

bearing only four seeds (or two seeds and two arrested ovules). This as well as 

No. 2865 I have here tentatively referred to this species. But there is a very 

interesting, somewhat intermediate, form, collected by Wilson (No. 3145, Veitch 

Exped. 1904; flowering specimens), the leaves of which very much resemble those 

of B. yunnanensis, while the single flowers with 8 ovules agree with those of B. 
diaphana. 

Here may also be added the description of a new variety collected by Mr, 
Purdom: 

Berheris diaphana, var. circumserrata Schneider, n. var. 

A typo differt fohis dense et graciliter circumserratis serraturis spinosis. 

Shensi: Tai-pei-shan, 1910, W. Purdom (No. 4). 

The specimen before me consists only of old gray twigs with rather strong 
spines, young leaves and single flowers. The leaves are roundish-ob ovate and dis- 
tinctly reticulate on both sides. The ovaries contain only four ovules. All things 
considered this form seems to be a rather distinct variety of B, diaphana.

bush 1-2 m, tall, fruit coral red). 

The type of this species had been collected by Potanin in northern Szech'uan 
(ad fl. Nereku, July 26, 1885). Originally I described the leaves as green on both 
sides, but this is an error. After comparing the type specimen with Wilson's 
specimens, I think the latter agree very well with B. Tischleri. Not having seen 
the flowers before, I have given above the more complete description. 

In the nervation of the leaves this species much resembles B. yunnanensis, but 
in its inflorescence with more numerous and smaller flowers and in the more elon- 
gated fruits B. Tischleri differs from that species. At first sight our species looks 
much like B. Silva-Taroitcana Schneider as there indicated. 

In the Araold Arboretum there is a cultivated plant, bearing the number 181, 
which seems to be nearly allied to B. Tischleri. 

Here may be added the description of a new species of this section based on 
material not collected during the Arnold Arboretum Expeditions : 

Berberis Ambrozyana Schneider, n. sp. 

Frutex 0.5O-1 m. altus, ut videtur dense et graciliter ramosus; ramuli jun lores 
(hornotini nondum vidi) brunnescentes, glabri, leviter angulati, vetustiores 
cinerascentes; internodia brevia, 0.3-1 cm. longa; spinae 1-3-fidae, graciles, 
flavescentea, acutae, mediae ad 12 mm. longae, subrotundae. Folia parvula, ad 8 
fasciculata, lanceolata v. oblanceolata integerrima apice obtusa, minime mucronu- 
lata, basim versus angustata, sessilia, supra viridia, subtus albo-pruinosa, utrinque, 
sed supeme distinctius, reticulata, ramulorum fioriferorum 8:1.5 ad 12:4 mm. 
magna. Fiores singuli, satis magni, lutei; pedicelli 2-3 mm. longi, basi bracteis 
rubescentibus circumdati; prophylla et sepala externa non vidi; sepala interna 
eximie lanceolata, acuta, fere ad 9 mm. longa; petala sepalis minora, anguste 
oblanceolata, apice bifida, basi vix unguiculata, glandulis 2 oblongis instructa; 
stamina apice distincte apiculata; ovaria stylosa, ovulis 5 (an semper?) sessihbus 
instructa. Fructus ignoti. 

Western Szech'uan: without locality, alt. 3200-3400 m., June 1904 (Veitch 
Exped. No. 3146«; shrub 0.5-1 m. tall). 

In the leaves this species closely resembles B. minuiiflora Schneider, III. 
Handh. Lauhholzk, II. 914 (B. brevipes (Franchet) Schneider, non Greene), 
but this Yunnan plant has much smaller flowers; the leaves have a different 
nervation and the fruits bear a sessile stigma. Berberis Ambrozyana may be more 
nearly related to Berberis parvifolia Sprague, in Kew Bull. Misc. Inform, 1908, 
445, which differs from it in its puberulous branchlets and in the smaller and more 
numerous flowers. I have not yet seen the type of Sprague's species (Wilson No. 
3154*). In the form of the sepals and petals Berberis Ambrozyana resembles the 
well-known Japanese Berberis Thunbergii,

maturus non visus. 

Western Szech'uan: Mupin, thickets, alt. 2000 m., June 1908 
(No. 2873). 

This species seems most closely related to Berhcris vermculosa Hemsley & 
Wilson which is easily distinguished by the terete, densely verruculose branches, 
by the more coriaceous leaves, with more and stronger spiny teeth and by the 
shorter pedicels. 

At the request of Mr. Wilson I have named this species for Dr. Asmy, an emi- 
nent surgeon in charge of the German Hospital, Chungking in recognition of 
valued service rendered to him in the years 1908 and 1911.

Western Szech'uan: Wa-shan, thickets, alt. 2500-3000 m., 
September and November 1908 (No. 1344; bush 1.30-2 m. high, 
fruit blue-black); Mupin, thickets, alt. 2000-2500 m., June and 
November 1908 (No. 1137; evergreen bush, 1.30-2 m. high, flowers 
yellow, fruit blue-black) ; southeast of Tachien-lu, alt. 2300-3000 ra., 
July and October 1908 (No, 1137*; bush 0.3-1 m. tall, flowers yellow, 
fruit black); Ching-chi Hsien, near Wa-wu-shan, woodlands, alt, 
2600 m., October 16, 1908 (No. 2874; shrub 0.5-0.75 m. tall); cliffs, 
July 1903, alt. 4000 m. (Veitch Exped. Nos. 3148, type, 3148^). 

The type (No. 3148) is distinguished by its finely pustulate branchleta, in this 
somewhat resembling B. verruculosa. In No. 1344 the branchlets also are some- 
what pustulate. This number bears fruits, which measure about 10:6 mm. and 
have sessile stigmaa. No. 1137 is distinguished by more numerous fascicles and 
somewhat smaller fruits, but the ovaries and fruits contain 4 ovules and 4 seeds. 
The leaves are up to 7: 1.5 cm. long, and the petioles are 1-4 mm. (not cm. as 
misprinted in my diagnosis) long. I think all these numbers belong to B. 
Gagnepainii, but No. 1137 may represent a somewhat different variety, of which I 
do not know the young branchlets. No. 1137* also has 5 ovules, but the flowers 
are borne on very long (3-4 cm.) pedicels, and the serrature of the leaves much 
resembles that of the leaves of B.Veitchii Schneider. No. 2814 differs in its rather 
large leaves (to 7; 2 cm.), some of which have a slight bloom on thelower surface. 
The unripe fruits contain four ovules. This number may represent a distinct 
variety.

The typical Berberis sanguinea is well distinguished by these characters. The 
preceding species is according to my opinion quite distinct. No. 2875 represents 
a form with smaller leaveS; the serration of which is very much like that of 5. 
triacanthophora Fedde, but the branches are yellow and distinctly sulcate and the 
flowers are short-pedicelled. The unripe fruitfi contain three ovules.

Western Hupeh: Hsing-shan Hsien, woods, alt. 1300-1600 m., 
June and November 1907 (No, 564, type); Fang Hsien, woodlands, 
not common, alt, 1600 m., November 1907 (No. 555). 

There is a little difference in the shape and serrature of the leaves of the two 
numbers. ^ No. 564 looks veiy much like the typical B. arguta, but Franchet's 
type specimen seems to be well distinguished by its rather thinner, more finely 
reticulated leaves (on both faces), which are without any hypoderm and bear 
finer and more numerous spines. The leaves of B. Sargentiana are furnished with 
a d^tinct epiderm-hke hypoderm like those of B. Wallickiana. 

Berberis Sargentiana is the only evergreen Barberry which has proved per- 
fectly hardy at the Arnold Arboretum and for this reason is one of the most de- 
sirable of the recent introduction as a garden plant.

1-2 m. tall). Yunnan: I-men district, A. Henry (No. 10618; shrub 
2.5 m., flowers; seems to be a form with more lanceolate leaves, 
4:0.8 cm.-9:1.2 cm,). Shensi: Tai-pei-shan, 1910, W. Purdom 

(No. 7; fruit unripe, but apparently pruinose, possibly a distinct 
species) . 

Berheris Julianas much resembles in the leaves B. Wallichiana De CandoIIe, 
of which I have seen the tj^e specimens of Wallich. These have somewhat 
thinner leaves, the hypoderm of which under the upper epidermis is not so well 
developed and resembles more the epidermis, so that it may be often overlooked. 
The leaves of B. Julianae are furnished with a similar but rather distinct hypo- 
derm. Besides this the ovules of the true B. Wallichiana possess a long funiculus, 
but it is possible that this character may not be constant. 

The type of B. Wallichiana was found in eastern Nepal, and I have seen it 
also from Shillong in the Khasi Hills in Assam, but I have not seen any Chinese 
specimens which represent the true B. Wallichiana. 

B. Wallichiana, var. microcarpa Hooker f. & Thomson, which comes from the 
same parts of Assam, also has stalked ovules, but I have not yet found a hypoderm- 
like layer beneath the epidermis of the leaves, which are lanceolate, thinner, 
somewhat shorter and smaller than those of the type. 

The plant from Shensi has leaves closely resembling those of cultivated forms 
m the Fruticetum Vilmorinianum at Les Barres, which represent the typical B. 
Sovlieana. The seeds from which these plants were raised were collected by Abb6 
Farges in the mountains near Cheng-kou, northeastern Szech'uan. The numbers 
of Giraldi, cited by me in Bull Herb. Boissier, s6r. 2, VIII. 199 (1908) under B. 
levis, may belong to this species, but this needs further investigation. In the 
Herbarium of the Hof-Museum at Vienna the flowering branch of No. 535 is rather 
different and may belong to B, Griffithiana Schneider, see p. 364. The fruiting 
branch agrees very well with that of No. 417.

Western Hupeh: without locality, June 1900 (Veitch Exped. No. 1138). 

In Bull. Herb. Boissier, s6r. 2, VIII. 197 (1908) I placed this specimen with B, 
acuminata^ but I now think that Franchet's species is different and that it may be 
distinguished by the much slighter and shorter serratures of the larger, somewhat 
thinner and a little more reticulate leaves. See also the key of the section Wal^ 
lichianae on page 367.

year, which are slightly angulate). 

In Bull. Herb. Boissier, b6t 2, VIII. 197 (1908), I have mistaken this form for 
B. acumiTiata Franchet, but the type of Franchet's species has round twigs, much 
more elongated, distinctly acuminate leaves and petals with short nectaries. It 
seems to be a very rare species, and also Wilson's No. 1138 (1900) from western 
Hupeh, cited by me also under B. acuminata (1. c), belongs to a different species, 
namely to B, Veitchii Schneider. In the reticulation of their leaves B. acumi-

The type of this species was collected by Griflith in Bhootan (No. 125; which 
is the same as No. 1741). The Vienna specimen, the only one I had seen in 1905, 
has small leaves, measuring from 2: 0.6 to 4: 1.2 cm., like those of B. Wallichiana 
var. -parvifolia Franchet. Both these specimens bear small papillae on the upper 
surface of the leaves. In the Kew Herbarium the number 1741 of Griffith, being 
the same as No. 125, bears leaves, of which the largest measure 7:1.6 cm., and I 
find similar leaves on No. 1742 of Griffith. These large leaves so much resemble 
the smaller leaves of B. Julianae and also the leaves of B. Bergmanniae, that one 
is inclined to unite these three species, but in their typical forms they look very dif- 
ferent. It will need further investigations to decide, whether there are three distinct 
species or only three forms of one rather variable species. I have not yet seen the 
fruit of B, Griffiihiana.

Delavay; Chi-tcho-tze, Houan-li-pin, March 12, 1883, Delavay (No. 485). 

To this species may belong, possibly, Wilson's No. 2879 from western Hupoh, 
June 1907, consisting of old twigs with rather young leaves, and some flowers 
(1-5), but the ovate leaves show a somewhat finer and narrower serration and no 
distinct reticulation on the upper surface. 

In shape, serration and nervation of the leaves B. Delavayi much resembles B, 
Hookeri Lemaire, but this species is well distinguished by its sulcate young twigs, 
its large flowers and its large fruits with 4-8 seeds. Berberis Hookeri may come 
from the eastern Himalaya (Sikkim, Bhootan) and Upper Burma, as indicated by 
me in Bull. Herb. Boissier, s6r. 2. VIII, 197 (1908), but now I am incUned to think, 
that it possibly may be of garden origin or that it came from South America, 
Therefore this species has been excluded from the following key. All the forms 
cited by me under B, Hookeri in the place quoted above may belong to B. Delavayi 
or to a very nearly related new species. 

As, with the exception of six, all the species of this difficult group have been 
enumerated above, a key of all the species of this section may be appended here.

A rather striking species, apparently most nearly related to the Himalayan B, 
cfntma Lmdley, which is well distinguished, however, by its puberulous branchleta, 
the longer stalked and numerous ovules and by the distinct styles. 

I take the liberty of dedicating this handsome species to His Imperial and Royal

Western Szech'uan: Tachien-lu, thickets, alt. 3200-3400 m., 
October 1910 (No. 4385; bush 1.5-2 m. tall, fruit red). Here belongs 
possibly the following specimen: west of Tachien-lu, alt. 3300 m., 
September 1908 (No. 1282; bush 1-2.60 m. tall, fruit sahnon-red). 

I am not quite sure whether No. 4385 really belongs to B. thibetica, which ra 
very similar in the shape of the leaves and in the inflorescence. Unfortunately 
Wilson's specimen is imperfect and lacks very young branchleta. Of B. thibetica 
I only have before me rather luxuriant cultivated flowering specimens and I have 
seen but one fruit. The fruits of No. 4385 seem to be somewhat smaller, and some 
of the leaves bear 1-4 short spines on each side towards the apex. 

Wilaon's No. 1282 consists of old, gray, somewhat angulate, fruiting branches; 
the inflorescences and fruit rather resemble those of No. 4385, but the leaves of 
No. 1282 are more lanceolate, rather acute and distinctly spinose-dentate with 
3-5 short pungent spines on each side. I cannot decide if this is only a variety of 
B. thibetica or if it represents a distinct species.

same: Min valley, alt. 2200 m., September 1904 (Veitch Exped. No. 
3156; bush 1-2 m. tall, fruit scarlet). 

This species is most nearly related to B. thihetica, which differs in the pruinose, 
not shining under surface of the leaves, and in its larger fruit with short style. 
Unfortunately the flowers of this new species have not been collected. 

This species is named in honor of Mr. Louis von Boschan, the vice-president of 
the Dendrological Society of Austria and Hungary. 

I cannot yet say whether the two following species belong to this section or to 
a new one, intermediate between the Sinenses and Heteropodae.

out locality, September 1904 (Veitch Exped. No. 3151*; fruiting 
branches); Mt. Omei, June 1904 (Veitch Exped. No. 4726). 

This species seems nearly related to the little known B, Tschonoskyana Regel 
from Japan of which I have not yet seen the young branches. Especially No. 
2867 looks very like the Japanese form, as described by Regel in Act. Hort. Petrop. 
II. 421 (1873) and as B. sikokiana by Yatabe, in Tokyo Bat. Mag. V. 283, (1891). 
At first sight this new species also resembles B. Tischleri Schneider which differs 
chiefly in having 4 ovules and an elongated fruit with a distinct style. 

Named in honor of His Excellency Count Ernst Silva Tarouca, the president 
of the Dendrological Society of Austria and Hungarj^, a famous garden maker and 
plant lover, to whom I am much indebted for assistance.

372 WILSON EXPEDITION TO CHINA 



This species appears to be most nearly related to B. Silva-Taroucana Schneider, 
which chiefly differs in the pruinose not shining under surface of the leaves, in its 
more irregularly racemose inflorescences and in its longer pedicels. Further in- 
vestigations are necessary, however, to decide whether B, Mouillacana must be 
considered as a variety of B. Silva-Taroucana, 

At the request of Mr. Wilson I have named this species for Dr. Mouillac, a dis- 
tinguished French army surgeon, at one time in charge of the Ecole de Medecine & 
R. C. Hospital, Chengtu, in appreciation of valued service rendered to him during 
the autumn of 1910. 

The following description and notes are based on material not collected in the 
Arnold Arboretum Expeditions.

Northern Chili: east Weichang, 1909, W. Purdom (Nos. 2, type, and 35, 
in part), 

I cannot find any other difference between the type and this form of northern 
ChiU, but there is another flowering branch on the same sheet with No. 35, of 
which all the leaves are distinctly serrate, while the flowers are quite like those of 
the other branch, which cannot be separated in any way from No. 2, The leaves 
of the serrate form resemble perfectly those of the following species, which possibly 
may be only a variety of B, Poiretii. 

Berberis Purdomii Schneider, n. sp. 

Frutex metralis, ut videtur habitu B. Poiretii; ramuli glabri, leviter sulcati v.

cm, longae, flavescentes, acutae, subtus sulcatae (in No. 345 spinae robustiores, 
ad 2 cm. longae). Folia ad 12 fasciculata, lanceolata, apice acuta, basim versus 
sensim in petiolum brevem decurrentia, 1:0.4 ad 4:0.8 cm. magna (in No. 345

Without having seen fully developed flowers it is impossible to say, whether the 
branch of Purdom's No. 35 of North Chih, Weichang, mentioned under B. Poiretii, 
var. weichangensis Schneider may not belong to B. Purdomii. This species cer- 
tainly is very closely related to B. Poiretii, but the leaves of B. Purdomii are 
serrate and show a more distinct nervation on both sides.

West Kansu: Min-chou, alt. 3200-3600 m., W, Purdom. 

This species differs from B. Poireiii Schneider and its varieties by its stronger 
simple spines, by its very small flowers and fruits and by its two-ovuled ovaries. 
It seems most closely related to B. Purdomii Schneider, of which I have only seen 
branches bearing very young flowers with all the leaves serrate, Berheris Vemae 
possibly may belong to the section Integerrimae. 

The species is named in compliment to Miss Vema Berger of La Mortola. 

There is another remarkable, but incomplete specimen from Weichang among 
Purdom's collection (without No., Chinese collectors). It bears very young in- 
florescences and the axes of some old ones. The specimen is very peculiar. The 
branches are apparently from an old shrub; the leaves are entire, narrowly spatu- 
late and up to 4 cm. long and 8 mm. broad; the racemes are borne on naked pedun- 
cles up to 2 cm. long, they show a tendency to become paniculate in their lower 
part and the lowest flower of each raceme is subtended by a leaf, a feature I have 
never observed so far; the old inflorescences are about 8 cm. long. It seems to 
be a new species which at present cannot be exactly determined; I hardly believe 
that it is a monstrosity.

BERBERIDACEAE. — BERBERIS 375 

This interesting plant, of which I have only seen a small branch with immature 
fruits, is readily distinguished by the reticulation and dentation of its leaves. 
It seems most nearly allied to B. duhia Schneider in Bull. Herb. Boissier, ser. 2, 
V. 663 (1900); VIII. 259 (1908) from western Mongolia and Kansu, which differs 
chiefly in the somewhat different reticulation and dentation of the smaller leaves 
and in the shorter pedicels.

To this species also belongs Wilson's No. 1320 ex Hort. Veitch. In his B. 
polyantha, Hemsley has mixed two different species. The true B. polyantha is repre- 
sented by Pratt's Nos. 206 and 704, but Pratt's No. 80 is quite different and belongs 
to this new species. Berbens polyantha has much thicker leaves with a very fine 
and narrow reticulation; the inflorescences are broader and looser, the bracts 
snorter and the elliptical dried fruits are swollen and bear a rather long style. 

mrbens Prattn seems also nearly related to B. hrevipaniculata Schneider in 
Bull. Herb. Bmssier, ser. 2, VIII. 263 (1908), which was collected by Henry, 
Ichang, May 1888 (No. 4675). But the last named species differs in its glabrous 
Drancnes and inflorescences, its smaller leaves, which are distinctly glaucous and 
papillose beneath and in its shorter panicles and bracts.

BERBERIDACEAE. — MAHONIA 379 



Mahonia Zemanii is a very distinct species, somewhat resembling in its lanceo- 
late leaves M. Fortunei Lindley which, however, differs by having the lowest pair 
of leaflets further from the base of the petiole. Before having seen flowers and 
mature fruits it is very difficult to indicate the correct position of this interesting 
species. There is a specimen collected by Henry (No. 3351), consisting only of 
three leaves which are not unlike those of Wilson's specimen. 

This species is named in compliment to Mr. Franz Zeman, head gardener of 
the Dendrological Society of Austria-Hungary in Pruhonitz, Bohemia.

This species is apparently most nearly related to M. nepalensis De Candolle, but 
the Chinese form differs in its fewer leaflets, of which the lowermost pair is rather 
distant from the base of the petiole, in its very short racemes and in its fewer 
(only two) ovules. The material being scanty the species needs further investi- 
gation,

ENUMERATIO SPECIERUM ASIATICARUM. 

Sectio Longibracteatae Fedde, inBo^ Jahrh. XXXI. 78 (Monog. Mahonia) (1901). 
To this section belong all species known from Asia and also one from the Pacific 
North America (71/. nervosa [Pursh] Nuttall). 

1. Mahonia japonica De CandoUe, Syst. II. 22 (1821). 

Ilex Japonica Thunberg, Fl. Jap. 77 (1784). 

Berheris japonica R. Brown ua Tuckey, C<mgo Exped, App.. 22 (1816). 

Szech'uan: Hants'ao-kan, Nanch'uan, anno 1891, A. von Rosthom (No. 174 
ex Fedde); Huang-hua-shan, Nanch'uan, A. von Rosthom (No. 1213 ex Fedde). 

I have not seen a specimen of a wild plant of this species, which seems to be 
very nearly related to M. nepalensis, from which it differs in its opaque, not shin- 
mg leaves rather paler below. Fedde says, that the bracts are acuminate and as 
long as the pedicels, but in my specimens of var. Bealei (Fortune) Fedde the bracts 
are only half as long as the pedicels and are not acuminate. Koehne (Deutsche 
Dendr. 165) states, that the ovaries of M. japonica contain about four ovules, while 
m M.nepalensis there are about seven. I could find only three in var. Bealei and 
also three, or rarely four, in many specimens of wild plants of M. nepalensis.

Yunnan: Mengtze, alt. 2000 m., woods, A. Henry (NoJOlSOi 
This species seems most nearly related to M. japonicaTfeTLdoWe and M. 
nepalenstspe CandoUe, but differs from both these species in the shape of the 
leaflets, which are not as shining as those of M. nepalensis and not dull hke those of 
M, japonica. Possibly it might be considered a variety of M. nepalensis, and there 
IS a specimen from the Khasia HUls collected by Ward (in Herb. Hof-Museum, 
Viemia) which only differs from this species in its shorter leaflets and in the shorter 
bracts of the pedicels; the filaments also are not dentate. But I beheve that all 
the Chinese forms, referred to M. nepalensis by Hemsley and other authors, repre- 
sent different species.

Fedde has not seen any Chinese specimen, and only cites specimens from Shensi, 
Szech'uan and Yunnan according to statements of other authors. I have not seen 
any of these Chinese specimens, but only those from Nepal, Sikkim and from 
Assam.

Kwangtung: North River, C. Ford (No. 17). 

From M. nepalensis De CandoUe to which it seems most nearly related, M. Fordii 
differs by the much paler and not shining under side of its differently shaped leaflets 
and by the short racemes. The leaflets somewhat resemble those of M. Sheridan 
niana, but this species belongs to the group with sessile stigmas, their leaflets 
have a rather different shape, and they are dull on the upper side. 

6. Mahonia polyodonta Fedde, in BoL Jakrh. XXXI. 126 {Monog. Mahonia) 
(1901). 

Szech'uan: without locality, A. von Rosthorn (No. 2043, ex Fedde). 

Of this species I have not seen a specimen. In the numerous spinose teeth of its 
leaflets it somewhat resembles the following species, but differs clearly from it in 
the characters given in the key on p. 381. 

7. Mahonia Veitchlorum Schneider, n. comb. 

Berbens Veitchiorum Hemsley & Wilson in Kew Bull Misc. Inform. 1906, 152.

Western Szech'uan: alt. 500-2200 m., July 1903, cliffs (Veitch Exped. No. 
3142; Bhrub 0.5-1 m. tall). 

This seems to be a good species well distinguished by the very long bracts of the 
pedicels and also by its leaves. Its nearest relation is M. polyodotan Fedde.

I ha,ve not seen a specimen of this species, but according to the description I 
think it may be different from all the species known to me.

16 (7-17) (1907). 

Annam : " Haut-Donnai, plateau de Lang-bian," Jacquet (ex Gagnepain). 

I know this species only from the description of the author. It may be most 
nearly related to M. nepalensis De Candolle and ikf. japonica De Candolle, from 
which It differs by the characters given in the key on p. 381. The stamens are 
apiculate and the filaments twice longer than the anthers.

This seems to be a distinct species, but the fruits are not known and I am not 
quite sure whether the style is entirely wanting.
