Leaf-sheaths terete, smooth, glabrous, subherbaceous, with a dense white spreading beard 2 1/2 lin. long at the nodes and another at the junction with the blade; ligules very short, membranous, ciliate and long-hairy from the back; blades linear, long-attenuated to a fine point, slightly narrower towards the base, to over 1 ft. long, 3 lin. broad, pale dull green, hairy on both sides, hairs very fine, sometimes from minute tubercles, margins very finely cartilaginous and scaberulous, midrib whitish, broad and flat above, prominent below, lateral nerves about 5 on each side. Panicle linear, up to 2 1/2 in. long; rhachis smooth, glabrous except at the shortly bearded nodes; lower branches about 4-nate, upper 2-nate or solitary, filiform, flexuous, undivided, up to over 1 in. long, glabrous and smooth or with a few short hairs at the thickened tips. Racemes few-noded, bearded at the nodes; joints 1 3/4 lin. long, densely ciliate, hairs reddish or purplish, up to 1 lin. long; pedicels very similar. Sessile spikelet lanceolate, acuminate, 3 1/2–4 lin. long, 1 lin. wide; lower glume firmly coriaceous up to half-way, then abruptly thinner, more or less chartaceous, 9-nerved, the coriaceous portion usually early turning a glossy brown or black, the remainder green, rigidly ciliate upwards and hairy on the sides; upper glume coriaceous up to three-quarters, then gradually thinner, as long as the lower, lanceolate, acuminate, 5-nerved, hairy upwards. Valve of lower floret linear-oblong, 3–3 1/2 lin. long, membranous, whitish or brownish, ciliate, 2-nerved; of upper floret ovate, shortly 2-lobed, 1 1/2 lin. long, ciliate; awn slender, about 1 in. long, kneed at and twisted below the middle. Column dark bronze-colour, minutely ciliate along the spirals, bristle pale. Lodicules densely ciliate. Pedicelled spikelet ♂ (?) or neuter, linear-lanceolate, 3 lin. long, greenish; glumes membranous, loosely hairy, lower about 7-, upper 5-nerved; valves linear-lanceolate to linear, hyaline, ciliate, lower entire, 2-nerved, upper 2-lobed, 1-nerved, with the nerve running out into a hair-like mucro.
