Peduncles 30-40 cm, glabrous; panicles 1-2.5 cm wide, linear; lowest nodes glabrous or sparsely pilose; rachises 10-35 cm, glabrous or sparsely pubescent; primary branches 6-18 cm, appressed; rame internodes 3-5 mm, glabrous. Sessile spikelets 7-10 mm long, 1.1-1.5 mm wide, brown. Callus hairs absent or to 2 mm, shorter than the spikelets, straw-colored; lower glumes scabrous, 5-veined; lower lemmas 6-8 mm, 2-veined; upper lemmas 0.9-1 times as long as the lower lemmas, 3-veined, entire; awns 17-24 mm, terete, straight or curved at the base; lodicule veins extending into hairlike projections; anthers 2. Pedicels 3-5 mm, glabrous. Pedicellate spikelets similar to the sessile spikelets. 2n = 30.
