Plants cespitose, with caudices, forming small, often rather dense clumps with few culms. Basal rosettes well-differentiated; blades 1-5 cm, ovate to lanceolate. Culms 15-55 cm tall, 0.2-0.8 mm thick, erect from geniculate bases; nodes glabrous; internodes mostly glabrous, or the lowest internodes sparsely appressed-pubescent basally; fall phase branching sparingly from the lower and midculm nodes. Cauline leaves 3-4; sheaths much shorter than the internodes, prominently veined, mostly glabrous, margins occasionally ciliate, ligules 0.2-0.7 mm, of hairs, without adjacent pseudoligules; blades 2-6 cm long, 1.5-6 mm wide, ascending, distant, flat, relatively thick, glabrous on both surfaces or the abaxial surfaces minutely puberulent, bases rounded, margins more or less prominently whitish-scabridulous, blades of the flag leaves much shorter than those of the lower leaves. Primary panicles 3-6 cm, nearly as wide as long, long-exserted, dense; branches wiry, spreading to ascending, usually scabridulous. Spikelets 1.3-1.7 mm long, less than 1 mm wide, ellipsoid, often purplish, densely puberulent, obtuse or subacute. Lower glumes usually less than 1/4 as long as the spikelets, broadly acute or obtuse; upper glumes and lower lemmas subequal, or the glumes slightly shorter, exceeded by the upper florets; lower florets sterile; upper florets 1.3-1.6 mm, ellipsoid, subacute. 2n = 18.
