A compactly tufted annual, 1–12 in. high. Culms geniculately ascending, or suberect, often very numerous, very slender, simple, 2–3-noded, glabrous, smooth; internodes usually exserted. Leaf-sheaths loosely bearded at the mouth, otherwise glabrous, or with a few scattered hairs, smooth, the lower striate, with scarious margins; ligule a ciliate rim; blade very narrowly linear, acute, 1/3–4 in. long, up to 3/4 lin. wide, flat, or setaceously convolute and filiform, flaccid or somewhat rigid, glabrous or sparingly hairy, smooth. Panicle contracted, usually dense, elliptic to oblong, 1/3–2 in. long, 2–7 lin. wide; branches and pedicels very slender; pedicels finally disarticulating from the branches, much shorter than the spikelets, scaberulous or minutely hispidulous. Spikelets narrow, 2–3 1/2 lin. long, greenish or purplish. Glumes glabrous, 1 7/8–3 lin. long, with rather broad white margins; lower oblong-lanceolate, acute, 5–7-nerved; upper narrowly elliptic-lanceolate or lanceolate, acute, 3–5-nerved. Florets 5–10. Valves broadly elliptic to broadly obovate-elliptic when flattened, 7/8–1 1/5 lin. long, 2-lobed, with obtuse or subacute lobes from one-sixth to one-fourth the length of the valve, emucronate, mucronate or awned from the sinus, with the very fine awn up to 1/4 lin. long, hairy below the middle with rather stiff blunt hairs, or glabrous on the back and only hairy towards the sides. Valvules as long as the valves. Anthers 1/8– 1/5 lin. long. Grain 2/5– 1/2 lin. long.
