Plants densely cespitose, with¬out rhizomes. Culms 30-150 (200) cm, glabrous or pubescent, sometimes scabrous. Sheaths closed for less than 1/3 their length, persistent, glabrous or pilose, smooth or scabrous, sometimes scabrous or pilose only distally or on the distal margins; collars usually densely pubescent or with a few hairs at the margins, sometimes glabrous; ligules 0.2-5 mm, usually ciliate, abaxial surfaces puberulent; blades 1-6.5 mm wide, conduplicate, convolute, or flat, 0.5-2(2.5) mm in diameter when convolute, deciduous, abaxial surfaces scabrous or smooth, glabrous or the bases pubescent, adaxial surfaces puberulent to pubescent, veins 9-15(17), ribs (3)5-15(17); abaxial sclerenchyma forming more or less continuous bands, sometimes reduced to small strands; adaxial sclerenchyma sometimes present; girders or pillars present at most veins. Inflorescences 10-25(30) cm, open, with (1)2(4) branches per node; branches spreading and lax. Spikelets 8-18(20) mm, borne towards the ends of the branches, with 3-6(8) florets. Glumes lanceolate, glabrous or sparsely scabrous at the apices; lower glumes (4)4.5-6.7(8) mm; upper glumes (5)6-10 mm; lemmas (7)7.5-11 mm, lanceolate, scabrous, puberulent, sometimes minutely bidentate, acute, usually awned, rarely unawned, awns (1)2-3(4) mm; paleas shorter than to longer than the lemmas, pubescent or glabrous on the margins, intercostal region usually puberulent distally; anthers (3)4-7.5(8.5) mm; ovary apices densely pubescent. 2n = 56.
