Perennial (?), base unknown. Culms very slender, erect or geniculately suberect, apparently 4- or more-noded, sparingly branched, terete, glabrous and smooth, upper internodes 3–5 in. long. Leaf-sheaths tight, terete, prominently finely striate, densely ciliate, otherwise glabrous, smooth; ligule reduced to a minutely ciliolate rim; blades lanceolate from a rounded and much constricted to subpetiolate base, finely acuminate, about 3 in. by 6–8 lin., spreading, flat, thin, green, very sparingly and finely hairy, margins scaberulous, midrib very slender, whitish below, primary lateral nerves 3–4, very fine and distant, distinct below only, secondary nerves 5–7 in the intervals connected by delicate cross-veins. Panicle exserted, erect, somewhat flexuous and delicate, 3–6 in. long, contracted or more or less open, divided to the third degree; common axis terete, filiform, smooth, lowest internodes 1–2 in. long, lower primary branches solitary or 2-nate, divided from 3/4–1 1/2 in. above the base, finely filiform, subangular, like the higher divisions smooth, or very slightly rough upwards, lower internodes long; secondary branchlets capillary, bearing 4–1 spikelets approximate upwards; pedicels very short to 1 1/2 lin. long, with truncate tips. Spikelets shortly lanceolate, acute, 1–1 1/4 lin. long, green with an apical tuft of fine long hairs from the upper glume. Glumes thinly membranous, unequal; lower lanceolate, acute, half the length of the spikelet or less, 1–3-nerved or almost nerveless, glabrous; upper corresponding in length and outline to the spikelet, 5–7-nerved, with some scattered short hairs on the back and sides and a slender tuft of long ones (up to 1 1/2 lin.) from the tip. Lower floret barren; valve very similar to the upper glume; valvule reduced to a tiny hyaline scale. Upper floret hermaphrodite, oblong, acute with a broad back, 1 lin. long, smooth, yellowish or whitish; valve and valvule papery; anthers 2/3 lin. long.
