Panicles 10-20 cm, erect, contracted; branches erect or ascending. Spikelets 15-30 mm, elliptic to lanceolate, terete to moderately laterally compressed, with 5-8 (12) florets. Glumes glabrous; lower glumes 7-9 mm, 1-veined; upper glumes 9-11 mm, 3-veined; lemmas 10-13 (15) mm, lanceolate, rounded over the midvein, backs and margins glabrous or sparsely pubescent, apices subulate to acute, entire; awns 5-7 mm, straight, arising less than 1.5 mm below the lemma apices; anthers 4-6.5 mm. 2n = 56.
