SECTION I. 
1. CEPHALOSTACHYUM CAPITATUM, Munro in Trans. Linn. Soc. xxvi. 139. 
А shrubby or sub-arborescent, semi-scandent bamboo. Culms 12 to 80 ft. long, thin- 
walled, yellow, strong below, loose above and so scandent on the branches of trees; 
nodes not very prominent; internodes long, often З ft. or more, 1 to li in. in diameter, 
walls :2 to °З in. thick. Culm-sheaths rather thin, papery on the upper part of the 
young culm, thicker on the lower joints, 6 to 12 in. long, 2 to 3 in. broad, covered on 
the back with pale-brown appressed pubescence, mouth triangular, truncate on the 
longer upper sheaths, on the shorter lower ones rounded with concave sinus; imperfect 
blade long, erect or recurved, hairy within, rounded at the base and decurrent on 
the sheath into rounded, sometimes fringed auricles; ligule narrow, serrate. Leaves pale 
green, whitish beneath, ovate-lanceolate, rounded at the base, unequally, into a short, -2 
to "3 in., petiole; ending above in a long, scabrous, twisted, setaceous, acuminate point; 
4 to 8 in. long, 1 to 2 in. broad, glabrous on both sides, rough on the edges; 
main vein prominent, pale, secondary veins 4 to 10 pairs, inconspicuous, intermediate 
6 to 7, no regular transverse veinlets, but distant pellucid dots which have the 
appearance of oblique transverse veinlets below; Jeaf-sheaths smooth, glabrous, shining, 
ending in а short auricle with a few, long-curved deciduous сШае. Inflorescence a 
dense, globular, terminal or axillary brownish head, 1 to 15 in. in diameter 
supported by broad, long-aristate, glabrous bracts, and consisting of many, long- 
aristate, keeled empty glumes or sterile spikelets and with a few shorter fertile 
spikelets. Spikelets “5 to 77 in. long, at the ends of short spikes, bearing 1 to 3 sterile 
flowers below; empty glumes 2, ovate, concave below and ending in a long scabrous 
awn, glabrous above, softly hairy below, many-nerved and with transverse veinlets, 
‘4 to 5 in. long by about :2 in. broad; flowering glume similar but narrower and 
with a shorter awn; palea as long as the flowering glume, convolute, thinner in 
texture, conspicuously nerved both longitudinally and transversely, 2-keeled, the 
keels close together and hairy between, shortly hairy and bluntly mucronate at 
tip; rachila produced, short. Lodicules 2 in. long, ovate-lanceolate, rounded and 
shortly ciliate above, 3—5-nerved, minutely papillose-hairy. Stamens exserted, filaments 
long; anthers long, narrow, bluntly emarginate at the apex. Ovary ovoid, stalked, 
produced into a long, thickened, often twisted style which is cleft at apex into 
2 short bifid hairy stigmas. Caryopsis chestnut-brown, smooth, shining, ovate, depress- 
ed, ending in a short conical beak formed by the persistent base of the style, and 
supported by the persistent glmnes and lodicules; pericarp thick, crustaceous. BAMBUSA
