Culms (15) 30-65 cm tall, 0.8-2 mm thick, glabrous or hispidulous; nodes glabrous or densely villous.

Spikelets 7-11 mm, purplish to pale, with 3-15 florets; lower glumes 5-7 mm; upper glumes 6-9 mm, generally equaling or exceeding the lowest florets; lemmas 4-6 mm, awned from between the lobes, awns 1-3.5 mm, apices bilobed, lobes 1.5-2.5 mm, rounded to truncate, lateral-veins forming a mucro to 1 mm; anthers 1, 1-1.5 mm.
