INDIAN BAMBUSE.E; GAMBLE. 43 
to plant for ornamental purposes, It is much used for scaffolding, and is very durable 
if well seasoned by immersion iu water. It is called Balku bans (Bengali) and Раша 
(Assamese); and to this species I attribute specimens sent by G. Mann under the names 
Sil baría, teli вата, from Sylhet, атлай, beru from the Garo Hills, and those collected by 
myself in the Western Duars under the name Zoro bans. It has been but rarely collected 
in flower: once by Roxburgh and once by Hamilton; by Hooker in the Purnea district 
.in 1849; by С. Mann іп Goalpara іп 1876; in Kamráp (Pani Ram Das, collector) 
in 1889; and by Captain Wood, Conservator of Forests, in Goruckpore, in 1881.

19. BAMBUSA VULGARIS, Schrad. in Wendl. Collect. Pl. ii. 96, 1. 47. 
A moderate-sized bamboo with rather distant culms. Culms bright green, yellow, or 
striped green and yellow, polished, shining, 20 to 50 ft. high, 2 to 4 in. in diameter 
or more, early branching; nodes hardly raised, but having a narrow ring usually 
covered with brown hairs; internodes 10 to 18 in, long; walls rather thin. Culm- 
sheaths 6 to 10 in. long, 7 to 9 in. broad, often beautifully streaked when young 
with green and yellow, rounded at top and concavely truncate, striate, clothed on the 
upper surface with thick appressed brown hairs, edges ciliate ; imperfect blade somewhat 
triangular, acute, 2 to 6 in. long and up to 4 in. broad, appressed-hairy on both 
. surfaces, margins revolute, rounded at the base and decurrent on the sheath, finally 
ending on both sides in a round, faleate, conspicuous auricle which is fringed by wavy 
stiff bristles; ligule "2 to ‘3 in. broad, dentate, sometimes long-fimbriate. Leaves linear- 
lanceolate, pale green, 6 to 10 in, long, 7 to 17 in. broad, rounded or attenuate 
at the base into a '2 in. long petiole; endin& above in a long twisted scabrous point; 
glabrous on both surfaces, except occasionally somewhat hairy beneath when young; 
scabrous on the margin and on adjacent nerves; main vein narrow, pale, secondary 
veins 6 to 8, intermediate 8 to 9, frequent pellucid glands giving the appearance 
beneath of transverse veinlets; Jeaf-sheaths striate, laxly hairy, ending in a smooth ciliate 
callus and а smooth rounded auricle with very few deciduous bristles; ligule short, 
shortly ciliate. Inflorescence a large leafy compound panicle bearing spicate branches 
ih heads of spikelets in bracteate clusters of З to 10, the clusters larger at the 
nodes ; rachis rounded or somewhat furrowed, scurfy, end segments hairy. Spikelets 
.6 to -8 in. long, oblong, acute, compressed, having the appearance of being bifid 
down the middle; bearing 1 to 2 empty glumes, then 6 to 10 flowers, and finally an 
imperfect flower ; rachillz cuneate, glabrous, not apparent ; empty glumes ovate-acute, 
ciliate at tip, many-nerved ; flowering glumes similar but larger; palea as long as, or a 
little longer than, flowering glume, bluntly acute, 2-keeled, white-ciliate on the keels, 
faintly 3-nerved. Lodicules unequal, usually two, ovate-oblong, the third longer, acute, 
long white-ciliate, 3-veined, very membranous. Stamens exserted, purple; anthers narrow, 
blunt, hairy, apiculate. Ovary narrowly oblong, hairy, surmounted by a long, thin, hairy 
style divided near the top into 3 short plumose stigmas. Caryopsis not known. Roth Nov.
