Plants perennial; densely cespitose. Culms 30-80 cm, erect or geniculate at the base, usually with 2 nodes. Leaves mostly basal, sometimes forming a basal tuft; sheaths smooth, glabrous; ligules 1.5-3.6 mm, rounded to acute; blades 12-25 cm long, strongly rolled, 0.3-0.5 mm in diameter, abaxial surfaces smooth or scabridulous, glabrous or hairy, often scabridulous or hairy proximally and essentially smooth and glabrous distally, adaxial surfaces scabrous, flag leaf blades 5-8 cm. Panicles 5-15 cm long, (2)4-12 cm wide, narrow to open, often nodding; branches ascending to spreading, flexuous, smooth or scabridulous. Spikelets 4-7 mm, ovate or U-shaped. Glumes exceeded by or subequal to the adjacent florets, 1-veined, acute; lower glumes 2.7-4.5 mm; upper glumes 3.5-5 mm; callus hairs to 1 mm; lemmas 3.3-5 mm, scabridulous or puberulent, hairs to 0.1 mm, apices acute, erose to 4-toothed, awns 3.7-7 mm, attached near the base of the lemma, strongly geniculate, geniculation below the lemma apices, distal segment 2.5-4.5 mm, pale; anthers 2-3 mm. 2n = 14, 26, 28, 32, 42.
