Culms 25-65 (77) cm, erect. Blades usually puberulent abaxially, sometimes glabrous. Spikes 7-20 cm, usually exserted, usually with 2 spikelets per node. Spikelets with (1) 2-4 (5) florets, lowermost floret functional. Glume awns 50-125 mm, entire; lemma awns 50-120 mm; paleas rarely with the veins extended as bristles.
