Plants not or loosely cespitose, shortly rhizomatous. Culms 45-100 cm, not forming corms; internodes sometimes scabridulous above the nodes. Sheaths glabrous or pilose; ligules 0.5-1.5 mm; blades 1.8-6 mm wide, abaxial surfaces glabrous, scabridulous, adaxial surfaces with hairs. Panicles 4-25 cm; branches 3.5-6 cm, appressed to spreading, straight, with 2-5 spikelets; pedicels sharply bent below the spikelets; disarticulation below the glumes. Spikelets 6-11 mm, with (1) 2 (4) bisexual florets, floret apices at about the same level; rachilla internodes 1.5-1.7 mm. Lower glumes 4.5-8 mm long, 3-4 mm wide, 5-7-veined; upper glumes 5-9 mm long, 2.5-3.5 mm wide, 5-6-veined; lemmas 6-11 mm, glabrous or scabrous, indurate, 9-11-veined, veins prominent, apices rounded to acute, unawned; paleas about 3/4 the length of the lemmas; anthers 1-3 mm; rudiments 2-3 mm, clublike, not resembling the bisexual florets, at a sharp angle to the rachilla. 2n = 18.
