72 ANNALS OF ROYAL BOTANIC GARDEN, CALCUTTA. 
Turkestani, and Japanese specimens in the Indian herbaria; the incompleteness of our 
knowledge of the floras of Persia, Afghanistan, and some parts of Turkestan; and 
our practically complete ignorance of the botany of the extreme Eastern Himalaya. 
The results of the partial exploration of the Chumbi Valley, which very clearly indi- 
cate the close relationship of the flora of the Himalayas east of Sikkim to the Floras of 
Yunnan, Hupeh, Setchwan, and Kansu, point to a rich harvest which is ready to be 
gathered in the inhospitable regions which stretch from the eastern frontier of Sikkim 
to the haunts of the Mishmis and Abors. 
THALICTRUM CULTRATUM, Wall. 
Hooker and Thomson in the Fora of Brit. Ind. are already of the opinion that T. platycarpum, 
H. f. et Т, is probably only an alpine state of T. cudtratum.  Lecoyer, whose views concerning this 
form are shared by the writer, formally reduced T. platycarpum to T. culiratum in his valuable mono- 
graph оп Thalictrum. Related to T. platycarpum is a form which was gathered by one of Dr. King's 
collectors somewhere between the northern frontier of Sikkim and Lhassa. The most important 
characters which distinguish the two are taken from the ripe fruit; and the differences are rather 
considerable. Nevertheless a careful investigation into their relationships makes the writer averse to 
claiming the new form as an independent species, and it appears to him preferable to consider it, like 
T. platycarpum, а subspecies of T. cultratum. We have thus— 
Subspecies I. currRATUM VERUM; a middle-sized ог tall herb (40—100 ст. high); pedicels 
elongate, filiform, 10—30 mm. long; anthers long-linear; stigma very narrowly winged; achenes distinctly 
stipitate (rarely one or another subsessile), attenuated towards the base, on transverse section nearly 
anceps, not wrinkled; lateral nerves slightly anastomosing upwards, without stalk 5—7 mm. long.— 
Kashmir; Garhwal; on the Kedar Kanta and elsewhere; Nipal; Sikkim, 8—12,000’. 
Subspecies II. PLATYCARPUM, H. f. et T.; middle-sized herb (25—50 em. high); pedicels elongate, 
filiform, 10—20 mm. long; anthers elliptic-oblong; stigma broadly or narrowly winged, subsagittate at 
the base; achenes manifestly stipitate, attenuated towards the base, on transverse section angular subcul- 
trate, not rugose; lateral nerves simple, without stalk 8—4 mm. long, scarcely convex along dorsal, very 
convex along ventral suture, minutely glandular; (wings of stigma revolute іп the ripe fruit).— Western 
Tibet; Garhwal; Southern Tibet, north of Sikkim. 
Subspecies III. TSANGENSE, P. Brühl; rather small (15—20 cm. high), very much branched; 
pedicels short, 3—4 mm. long; anthers linear; stigma broadly winged, very acutely triangular, wings 
erose and laciniate; achenes subsessile, asymmetrically obovoid, dorsally gibbous near apex, ventrally 
very convex, on transverse section subangular, glabrous, attenuated towards the base, lateral nerves 
scarcely anastomosing, 2:5—39 mm. long, wings of stigma reflexed in the fruit.—Tibet, north of Sikkim 
(King’s Collector). 
Pirate 102. Thalictrum culiratum, Wall.: the letters c, В (misprint for p), t refer to subspecies cultratum verum, 
platycarpum, and tsangense respectively. 1, upper part of inflorescence of T. cultratum verum ; 2, Т. platycarpum; 3, 
Т. tsangense ; 4-6, sepals; 7-9, stamens; 10 and 11, head of achenes; 12, pistil; 13-15, ripe achenes, and 16-18, 
stigmas, of Т. culiratum, T. platycarpum, Т. tsangense resp.; all of natural size. 
CLEMATIS MONTANA, Ham. 
Shrub or urdershrub, climbing or sarmentose; flower-bearing branchlets from the 
axils of fallen leaves, usually much shortened, scaly at the base; leaves trifoliate; leaflets 
membranous to subcoriaceous, rarely quite leathery, mostly ovate or ovate-lanceolate, 
serrate or serrately incised, rarely quite entire; flowers usually crowded ; pedicels 3—15 em.
