densely cæspitose; innovation shoots intravaginal; culms slender, simple, rarely with a lateral flowering branch from the upper part, 1–2 ft. long, more or less compressed below, glabrous, 2–3 noded; leaves mainly crowded at the base; lower sheaths compressed, villous at the very base, appressedly and usually fugaciously hirsute above, or glabrous except near the mouth; upper terete, tight, shorter than the internodes, the uppermost sometimes tumid with a minute blade; ligules truncate, ciliolate with long hairs from behind; blades very narrow, linear, acute, generally tightly convolute and filiform, 1/3–1 ft. by about 1 lin., erect, rigid, sulcate, flexuous or curved, glabrous or hirsute at the base; raceme (false spike) 3–6 in. long, rather stout, strict or flexuous, whitish silky, joints rather stout or slender, to 2 lin. long, long and densely villous on the back; sessile spikelets lanceolate, acuminate, 4–5 lin. long; lower glume herbaceous to chartaceous, bi-cuspidate, villous to subglabrous on the back, intracarinal nerves about 6, evanescent below, keels acute, long and densely ciliate, in the lower part with tubercle-based tufts of hairs, and with oil-glands nearly all along, callus short, obtuse, hairy; upper glume acute, 3-nerved, pubescent along the fine prominent keel, margins softly ciliate; lower valve lanceolate, 2 1/2 lin. long, 2-nerved; upper oblong-lanceolate, 2 lin. long, 3-nerved; margins of both softly ciliate; pale very minute; anthers 2 lin. long; pedicelled spikelets 2 1/2–3 lin. long, pedicels up to 2 lin. long, like the joints; lower glume entire or subentire, one margin inflexed, the other spreading, intracarinal nerves 5–6; upper glume 3–5-nerved; otherwise as in the sessile spikelet, except the sex. null
