Perennial; culms tufted, erect; ligule a ring of short hairs, about 0.2 mm long. Inflorescence a contracted panicle. Spikelets 1-flowered, lanceolate, about 1.8 mm long grayish-green or purplish; glumes thin, unequal; lower glume ovate, truncate, nerveless, about 1/3 as long as the spikelet; upper glume ovate, pointed, about 2/3 as long as the spikelet, 1-nerved; lemma papery, ovate-lanceolate, 3-nerved, but lateral ones obscure, as long as the spikelet; palea boat-shaped in side view; anthers 3, minute, about 0.2 mm long. Fruit an utricle, brownish, elliptical-obovate, 1 mm long, with net-like markings, hilum punctiform, embryo 1/2 the length of the grain.
