70 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. 
The black-fringed spikelets and naked auricles of Ше culm-sheaths distinguish 
this species. Kurz says it is called Bamboo lengka in Malay, and that it is gregarious 
in the Andamans. То this species also I attribute the specimens sent by С. Mann 
from the Garo Hills, Assam, in 1889, under the name Washut (Garo), though the culm- 
sheaths and their imperfect blades are longer; also the specimen sent. from Khorda, 
Orissa, by Babu Sree Dhur Chakravarti under the name Bolangi bans. Mann says that 
Washut is used in hut building and for basket work.

An evergreen or occasionally deciduous, densely tufted bamboo. Culms elongate, 
carved, 20 to 30 ft. long, 5 to 1 in. in diameter, greyish-green, hispid above; 
nodes raised in a ring formed by the base of the sheath; internodes 6 to 15 in. 
long, walls moderately thick, ' to 3 in. Culm-sheaths 4 to 8 in. long by about 
6 in. broad, at first covered with dense tawny appressed hairs, afterwards smooth, 
somewhat truncated, folded and coriaceous at the base; ending at the truncated mouth in a 
narrow, slightly auricled, naked band; imperfect blade as long, and often somewhat longer 
than, the sheath, lanceolate, acuminate, broad and rounded at the base and decurrent; 
ligule very long, 5 to 1 in. truncate, toothed. Leaves linear-lanceolate, 6 to 8 in. 
long, “7 to 1 in. broad; rounded at the base into а short :1 in. petiole; at the tip 
produced in а setaceous point; glabrous above, except for scabrous points near tho 
margins, glaucescent beneath, scabrous on one or both margins; secondary veins 
6 to 8, intermediate usually 4 to 5; no regular transverse veinlets, but frequent 
pellucid glands having that appearance on the lower surface; leaf-sheaths . smooth, 
striate, ending in a smooth callus and truncate edge; ligule rather long, faintly 
ciliate. . Inflorescence a large spreading panicle of spicate branchlets; spikelets in verticils 
of about 10 % 20, supported by yellow chaffy white ciliate bracts; rachis smooth, 
slender, 1 to З in. long between the verticils; spikelets slender, "6 to "8 in. long, 
often eurved, “1 in. broad, those bearing fertile flowers mixed with few sterile ones; 
empty glumes l to 2, ovate-acute, white-ciliate; then: one male flower, followed 
by 1 or 2 hermaphrodite flowers; flowering glumes elliptic, acute or faintly emarginate, 
many-nerved, white-ciliate on the low, convolute; palea shorter, often much shorter, 
ovate obtuse, 2-keeled, ciliate on the keels, that of last flower not keeled, convolute, 
ciliate only at the tip. Stamens long, exserted; filaments at first connected in a short 
thick tube, afterwards in a long, very membranous one; anthers long, greenish-yellow,
