Sheaths keeled, sparsely pubescent, margins ciliate distally; ligules to 1 mm, of hairs; blades 15-30 cm long, usually less than 5 mm wide, densely pubescent on both surfaces. Panicles 5-15 cm, slender, attenuate, interrupted, sparsely flowered; rachises pubescent; branches mostly shorter than 10 mm, villous; bristles usually solitary, 4-7 mm, antrorsely scabrous. Spikelets about 2 mm, ovate-lanceolate. Lower glumes about 1/3 as long as the spikelets, 3-veined; upper glumes about 1/2 as long as the spikelets, 5-7-veined; lower lemmas equaling the upper lemmas; lower paleas equaling the upper paleas, broad; upper lemmas finely and distinctly transversely rugose; upper paleas similar to the upper lemmas. 2n = unknown.
