Plants annual. Culms (22)30-70 cm, erect or ascending. Sheaths usually densely pilose; upper sheaths sometimes pubescent or glabrous; ligules 1-2.2 mm, pilose, obtuse, lacerate; blades 10-20 cm long, 2-4 mm wide, usually pilose on both surfaces. Panicles 10-22 cm long, 4-13 cm wide, open, nodding; branches usually longer than the spikelets, ascending to spreading or somewhat drooping, slender, flexuous, sometimes sinuous, often with more than 1 spikelet. Spikelets 20-40 mm, lanceolate, terete to moderately laterally compressed; florets 6-12, bases concealed at maturity; rachilla internodes concealed at maturity. Glumes smooth or scabrous; lower glumes 4.5-7 mm, (3)5-veined; upper glumes 5-8 mm, 7-veined; lemmas 7-9 mm long, 1.2-2.2 mm wide, lanceolate, coriaceous, smooth proximally, scabrous on the distal 1/2, obscurely (7)9-veined, rounded over the midvein, margins hyaline, 0.3-0.6 mm wide, obtusely angled above the middle, not inrolled at maturity, apices acute, bifid, teeth shorter than 1 mm; awns 8-13 mm, strongly divergent at maturity, sometimes erect, twisted, flattened at the base, arising 1.5 mm or more below the lemma apices; anthers 1-1.5 mm.
