Plants perennial; cespitose, not rhizomatous. Culms (15)20-60 (70) cm, somewhat decumbent, 1 or more nodes exposed; internodes hispidulous below the nodes. Leaves somewhat basally concentrated, most blades not reaching more than (1/4)1/2 of the plant height; sheaths usually a little shorter than the internodes, not keeled, scabridulous, margins hyaline, basal sheaths rounded, not becoming spirally coiled when old; ligules 2-9 mm, hyaline, acute, lacerate, often with lateral lobes; blades 4-10(16) cm long, 1-2.2 mm wide, not arcuate, flat, folded, or involute, scabrous, often glaucous, midveins and margins not thickened, green. Panicles 12-30 cm long, 5-20 cm wide, diffuse; primary branches 1-10 cm, diverging 30-80° from the rachises, naked basally; pedicels 1-4(6) mm. Spikelets 2.5-4.2 mm. Glumes equal, 1.4-2.5 mm, 1-veined, apices scabridulous, acute to acuminate, minutely erose, unawned or awned, awns to 1 mm; lemmas 2.5-4.2 mm, narrowly elliptic, usually purplish, scabrous distally, appressed-pubescent on the lower 1/2 - 3/4 of the margins and midveins, apices acuminate, awned, awns 0.5-4.2 mm; paleas 2.5-3.5 mm, narrowly elliptic, intercostal region sparsely pubescent, apices acuminate, with 2 short (0.1-0.2 mm) awns; anthers 1.5-2.1 mm, greenish. Caryopses 1.9-2.3 mm, fusiform, brownish. 2n = 80, 82.
