Culm tufted, up to 20 cm long. Blade linear-lanceolate, 4-6 mm wide, 5-nerved, covered with tubercular hairs along the lateral nerves. Inflorescence a large open panicle, about 20 cm long. Spikelets usually 3-flowered, about 1.1 mm long, upper-most floret reduced to merely a rachilla; glumes chartaceous, lanceolate, scabrous on backside, 1-nerved; the lower glume about 1 mm long, slightly shorter than the upper; lemma ovate-lanceolate, subcoriaceous, 3 nerved, margins slightly inrolled, pubescent on backside; palea chartaceous, elliptical, 2-keeled, sparingly hispid on back, nearly as long as the lemma. Caryopsis about 0.6 mm long, surface reticulate, rounded at the apex, acute at base; embryo 1/3 the length of the caryopsis.
