Plants annual. Culms 20-110 cm, erect or ascending. Lower sheaths densely hairy, hairs stiff, often retrorse; upper sheaths glabrous or pubescent; ligules 1-2 mm, glabrous or hairy, erose; blades 7-18 cm long, 1-4 mm wide, pilose on both surfaces. Panicles 4-16 cm long, 2-3 cm wide, erect, open; branches sometimes longer than the spikelets, slender, usually ascending, slightly curved or straight. Spikelets 12-20 mm, lanceolate, terete to moderately laterally compressed; florets 5-6, bases concealed at maturity; rachilla internodes 1-1.5 mm, concealed at maturity. Glumes smooth to scabrous; lower glumes 4-6 mm, (3)5-veined; upper glumes 4-7 mm, 7-veined; lemmas 6.5-8 mm long, 3-4.5 mm wide, elliptic to lanceolate, coriaceous, backs smooth, distinctly 7(9)-veined, not ribbed, rounded over the midvein, margins scabrous, rounded, not inrolled at maturity, apices acute to obtuse, bifid, teeth shorter than 1 mm; awns 5-9 mm, all more or less equal in length, straight, arising less than 1.5 mm below the lemma apices; anthers 1.5-3 mm. Caryopses shorter than the paleas, thin, weakly inrolled or flat. 2n = 28.
