Culms tufted from a knotty rootstock, slender, stiffly erect, 60–150 cm tall. Leaf sheaths glabrous or pilose; leaf blades lanceolate, 5–30 × 2–5 cm, glabrous or with long hairs on both surfaces, base rounded to a 8–12 mm pseudopetiole; ligule brown, hispid on backside. Inflorescence 10–25 cm; racemes few, 5–10 cm, loosely spiculate, erect at first with appressed spikelets, later obliquely spreading and spikelets patent; pedicels short, thick. Spikelets narrowly lanceolate, subterete, 7–12 mm, base glabrous or hairy; glumes ovate, rounded on back, subleathery with membranous margins; lower glume 3–4.5 mm, 5-veined, glabrous or stiffly hairy near margins and apex; upper glume ca. 5 mm, 5–7-veined, glabrous; lemma of fertile floret oblong with straight back, not keeled, 6–7 mm; palea lanceolate, hyaline; awn of fertile and sterile lemmas 1.5–2 mm. Fl. and fr. Jun–Sep. 2n = 48*.

This species is used for medicinal purposes. The leaves are reminiscent of those of bamboos. The barbed awns catch in the fur of passing animals, effecting dispersal of the spikelet.
