108 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. 
consisting of many fertile spikelets among empty aristate bracts or sterile smaller 
spikelets. Spikelets elongate, "8 to 1 in. long, glabrous; empty glumes "6 to ‘7 in., ovate at 
base, long-scabrous-aristate above, glabrous, striate, with 17 to 19 nerves; ps glume 
similar but more elongate and more shortly aristate, 21- to 23-nerved, 2d transversely 
veined; palea rather longer than flowering glume, thin, ovate-lanceolate, bifid at apex, the 
tips mucronate, pubescent, 2-keeled, the keels close together, 5-6-nerved and transversely 
nerved on either side; гаси а produced, short. Гофсиез linear-lanceolate or spathulate, 
blunt, 3- to 5-пегуед, minutely ciliate above and papilose on the sides. Stamens long 
exserted, drooping; anthers sharply apiculate or forked at the tip. Ovary narrowly 
ellipsoid, produced into a thick style, divided above into 2 short stigmas. Caryopsis 
chestnut brown, similar to that of С. latifolium, but more rounded at top; pericarp 
crustaceous. 
Eastern Haie in the hills of British Bhutan about Dumsong, Laba and Song- 
сћопоји, 6,000 to 8,000 ft., also in the Daphla Hills at Shamgarh, 6,800 ft.; collected in 
flower by G. A. Gammie in 1889 and 1892, in leaf only; in 1880 by myself, by 
Е. Fuchs іп 1877 (2), and by Lister in the Daphla Hills in 1875. 
I first met with this beautiful species when it was sent to me by the late 
Mr. E. Fuchs, Assistant Conservator of the Tista Forests, who had taken some con- 
siderable trouble to collect bamboos there; and thinking it to be a Cephalostachyum, not 
traceable in Munro’s Monograph, I gave it later on the Herbarium name of С. Fuchsianum, 
to which I now adhere. I afterwards found it myself in 1880. It is apparently quite а 
loeal species, but it is now in cultivation, owing to the distribution of the seed collected 
by Mr. Gammie. It will probably be found to succeed in Europe, perhaps even іп 
the open аш, The Lepchas know it by the name of Райт. It is easily recognized 
by the long fringes to the leaf sheaths, the deeply indented top of the culm-sheath, and 
the bifid palea.

А deciduous, arboreous, tufted bamboo. Culms erect, glaucous-green, somewhat 
whitish-puberulous below the nodes, 30 to 40 ft. high, 2 to 3 in. in diameter; nodes 
scarcely thickened; internodes 12 to 18 in. long, walls very thin. Culm-sheaths much 
shorter than internodes, 4 to 6 in. long, 6 to 8 in. broad, densely covered with black, 
stiff, deciduous hairs, afterwards polished chestnut brown; imperfect blade 2 in. long, 
ovate, cordate, cuspidate, densely hairy within, decurrent into а wavy fringe bordering 
the top of the sheath and ending on either side in a rounded auricle; both fringe and 
auricle edged with long, stiff, curved, white bristles, which are often "5 іп, long; ligule very 
narrow, entire. Leaves variable, linear-lanceolate, 6 to 14 in. long by 1 to 15 and even 
25 in. broad, thin; rounded or cuneate at the base into a short "2 in, petiole; above 
subulate, acuminate, with а scabrous point; scabrous on the edges and rough on both sides,
