Tufted annual or short-lived perennial; ligules ovate to lanceolate, 10-20 mm long, margins decurrent to the sheath; leaf-blades cauline; linear, 25-80 cm long, 5-30 mm wide. Panicle open, loose, pendent when fruiting. Spikelets flattened, elliptic, 6-10 mm long; glumes minute, vestigial lemmas subulate, glabrous, 2-4 mm long; fertile lemma 5-nerved, hard, hispidulous, as long as spikelet; palea same texture and length as lemma, 3-nerved. Grain 5 mm long.
