Culms (30) 50-80 (110) cm, sometimes slightly decumbent at the base, otherwise erect. Ligules 0.5-1.5 mm; blades 2-4 (5) mm wide, glabrous or adaxial surfaces pilose. Panicles 7-13 (17) cm, open or closed, often reduced to racemes in depauperate plants. Spikelets 11.5-17 mm. Glumes glabrous, acute; lower glumes 4.2-6.2 mm, faintly (1) 3-5-veined; upper glumes 6-9 mm, faintly (3) 5-veined; lemmas 8-10.5 (12) mm; awns 8-15 mm, as long as or longer than the lemma bodies, somewhat twisted and divergent or slightly geniculate; anthers 1.4-2 mm. 2n = 20.
