Sheaths glabrous or slightly scabrous; ligules 1-3 mm; blades 4-20 cm long, (1)6-15 mm wide, flaccid, surfaces glabrous or puberulent or the abaxial surfaces sometimes densely pilose, margins hispid. Panicles 10-25 cm, long-exserted at maturity, with 1 branch per node; branches 4-8 cm, spreading, naked on the lower 73, spikelets more or less appressed, scarcely imbricate. Spikelets 2.5-3.6 mm long, 0.4-1.2 mm wide, oblong or ovate. Lemmas ciliate to nearly-glabrous on the keels and margins, glabrous or short-pubescent on the body; paleas glabrous or slighdy ciliate on the keels; anthers 2.
