6. OxyTENANTHERA MONOSTIGMA, Beddome Flora Sylv. ссхххш. 
A medium-sized strong bamboo. Culms nearly solid, 10 to 15 ft. or more high, about 
1 in. in diameter, densely covered with soft, pale yellow, velvety tomentum; nodes not very 
prominent; internodes long. Culm-sheaths thin, papery at the edges, striate, sparsely covered 
with white appressed stiff hairs, 6 to 9 in. long, about 3 in. at the base, and gradually 
attenuate upwards to the apex which is rounded on either side and has a deep sinus, to 
the bottom of which the imperfect blade is affixed; imperfect blade about 3 in. long, linear- 
lanceolate, striate; ligule long, often deeply fimbriate. Leaves variable in size according as 
they grow on leaf-branches. or mixed with the flower spikes, pale green, 6 to 8 in. long, 
1:5 in. broad, linear-lanceolate, acuminate, rounded at the base unequally into a :2 to °3 
in. flat petiole; ending above in a setaceous twisted point; glabrous above, except for the 
. scabrous points on veins near the margin and on the midrib, sparsely hairy and pale 
beneath, scabrous on one side of the margin; main vein yellow shining beneath, inconspicuous 
above, secondary veins 7 to 12, intermediate 5 to 7; leaf-sheaths striate, glabrous, or with 
scattered appressed hairs produced at the mouth to meet the ligule; Пуше long, often "3 
in., acute or rounded. Inflorescence a large terminal panicle of spicate branchlets bearing 
dense globular heads of spikelets, heads often very large, especially at the main nodes 
of the central rachis, where they often reach 2 to 2:5 in. in diameter; rachis rounded, 
smoóth, striate. Spikelets "8 to 1 in. long, glabrous, less than 1 in. broad, long-spinose- 
apiculate, very numerous, fertile and sterile about equal in numbers; only one flower; empty 
glumes 2 to 3, lower small, ovate-mucronate, upper ovate-lanceolate, mucronate; flowering 
glume long, narrow, linear-lanceolate, long-mucronate, convolute; palea shorter than flowering 
glume, concave, not keeled, blunt. Stamens exserted, tube short and thick at first, after- 
wards long-cylindric ; anthers long, about '2 to "3 in., narrow, long bristly-apiculate, the 
bristle somewhat hairy at the apex. Ovary ovate-acuminate, rounded, glabrous, ending 
in a long glabrous sfyle, terminating in a feathery, or, in older flowers, a curved, 
thickened stigma. Caryopsis narrow, linear-oblong, grooved, ending in а conical mucro 
formed by the persistent base of the style, embryo conspicuous, Beddome Icones Plant.

I feel sure I am right in identifying Bambusa Ritcheyi, Munro, with Oxytenanthera 
monostigma, Beddome; and to this Munro himself (see MS. note in Kew Herbarium) agreed. 
The species is very well marked by the velvety culms, narrow culm-sheaths, long narrow 
pointed spikelets with only one flower, and glabrous ovary and style. The leaves are 
very variable, but Brandis specimens and Munro's descriptions agree well with those sent 
by Bombay officers, and the narrower, smaller leaves belong mostly to flowering branchlets.
