Culms 15-45 cm, erect to decumbent. Blades usually puberulent abaxially, sometimes glabrous. Spikes 4-15 cm, exserted or partly included, usually with 2 spikelets per node. Spikelets with (1) 2-3 (4) fertile florets, lowest 1-2 florets sterile and glumelike. Glume awns 35-85 mm, often split into 2, sometimes 3, unequal divisions; lemma awns 25-75 mm, usually exceeded by those of the glumes; paleas with the veins extended as bristles.
