SECTION I. 
1. DAMBUSA Тигра, Roxb. Hort. Beng. 25 (1814). 
An evergreen or deciduous, cæspitose, arboreous, gregarious bamboo. Culms green or 
glabrous when young, grey-green when older, sometimes streaked with yellow, 20 to 70 
feet high, not or little branched below, 2 to 4 in. in diameter; nodes not swollen, 
the lower ones fibrous-rooted; internodes 1 to 2 feet long, white-scurfy when very 
young, ringed with white below the nodes, the walls thin, '3 to "5 in.; branches 
many from nearly all nodes, those of lowest ones thin, nearly leafless, horizontal. 
Culm-sheaths about 6 to 9 in. long, 6 to 10 in. broad, smooth or whitish-powdered 
or covered with appressed brown hairs without, often white-powdered within; slightly 
attenuate upwards and rounded or triangularly truncate at top; imperfect blade 
broadly triangular, reniform or cordate, cuspidate, erect, hairy within, the base decurrent 
into rounded, large, long-frmged auricles, or a wavy narrow-fringed band along the upper 
edge -f the sheath; ligule narrow, entire. Leaves linear-oblong ог linear-lanceolate, 
6 to 10 in. long by ‘7 to 15 in. broad; usually rounded at the base into a short 
1 in., often hairy petiole; acuminate above in a subulate twisted point; glabrous 
above, except for the scabrous veins near the margin on one side, glaucescent and 
puberulous beneath ; scabrous on the edges; main vein rather narrow, secondary veins 
6 to 10, intermediate 7 to 8, pellucid glands faint, scanty; leaf-sheath striate, glabrous, 
ending in a smooth callus and an oblong rounded auricle, fringed with long, thin, 
whitish bristles; ligule narrow, inconspicuous. Inflorescence variable, sometimes an immense 
radical leafless panicle, sometimes a short leafy paniculate or spicate branch; branches 
spicate, bearing interrupted clusters of few (1 to 5) usually fertile long spikelets, supported 
by shining chaffy bracts; rachis smooth, striate. Spikelets variable in length, 1 to 3 in. 
long, "2 in. broad, sessile, glabrous, e оса] and acute at first, afterwards divided into 
many flowers separated by conspicuous гаси е, bearing first 1 to 2 short bracts, then 9 
to 4 usually gemmiparous empty glumes, then 4 to 6 fertile flowers, and finally 1 or 2 
imperfect or male terminal flowers; empty glumes acute, many-nerved ; flowering glume 
many-nerved, glabrous, striate, 5 to 1 im, long, "3 in. broad, ovate acute or acuminate, 
mucronate, sometimes minutely ciliate on the edges; palea rather shorter, boat-shaped,
