Plants perennial, cespitose. Culms 7-68 cm tall, erect, lowest internode 1-1.5 mm thick, striate, smooth, glabrous except hairy just below the inflorescence.

Leaves mostly basal; sheaths hairy on the lower portion, becoming glabrous and smooth distally; auricles 0.2-0.6 mm long; ligules 0.1-0.5 mm long, truncate to obtuse; blades 3.5-5.5(17.5) cm long and 1.7-4 mm wide, wt 7-16 veins, flat to loosely inrolled on drying, abaxial surface glabrous to densely hairy, upper surface sparsely to densely pilose, tips acute to acuminate.

Inflorescence spikelike, 1.5-6 long, with 4-10 spikelets; rachis surfaces pubescent to pilose, with retrorse hairs, prolonged beyond the base of the distal spikelet; middle internodes 2-3 mm long.

Spikelets 7-13 mm long, solitary, tangential to the rachis, appressed to ascending, not pedicellate, with 2-3 florets.

Glumes about equal, 4.5-7 mm long, 3-6(7)-veined at midlength, ovate-lanceolate to lanceolate, glabrous or almost so, sometimes awn-tipped, the awn to1.75 mm long. Lemmas 4.5-7 mm long, glabrous and usually mostly smooth, sometimes scabridulous, awn-tipped, the awn 1.5-2.5 mm long. Palea 5.4-6 mm long, the keels coarsely scabrous, their tips separated by 0.25-0.5 mm. Anthers 2.25-5 mm long.
