Plants annual. Culms 30-70 cm, erect or ascending. Sheaths often densely hairy with soft, white hairs; ligules 1-2 mm, hairy, obtuse, erose; blades 10-30 cm long, 3-5 mm wide, glabrous or pubescent. Panicles 5-15 cm long, 2-9 cm wide, erect, densely contracted when immature, more open with age; branches usually shorter than the spikelets, rigid, ascending to slightly spreading, slightly curved or straight. Spikelets 20-50 mm, lanceolate, terete to moderately laterally compressed, often 2+ per node; florets 7-20, bases concealed at maturity; rachilla internodes concealed at maturity. Glumes pilose; lower glumes 5-9 mm, 3-5-veined: upper glumes 8-12 mm, 5-7-veined; lemmas 11-20 mm long, 1.8-2.5 mm wide, lanceolate, pilose, obscurely 7-veined, rounded over the midvein, margins rounded, not inrolled at maturity, apices acute, bifid, teeth shorter than 1 mm; awns 6-12 mm, to 20 mm on some distal lemmas, divaricate when mature, arising 1.5 mm or more below the lemma apices; anthers 1-1.5 mm.
