Treatment appears in FNA Volume 25. Treatment on page 685.

Plants cespitose; with short, knotty, rhizomatous bases. Culms 60-120 cm, glabrous throughout. Sheaths glabrous or pilose on the margins; ligules 0.5-1 mm, membranous, shortly ciliate; blades 16-30 cm long, 2-4 mm wide, adaxial surfaces with hairs to 5 mm basally, glabrous distally, margins ciliate near the bases. Rames 6-15 cm; internodes pilose. Sessile spikelets 6-8 mm; calluses about 1 mm, antrorsely hirsute; lower glumes usually mostly glabrous, rarely sparsely pilose dorsally, keels ciliate distally, apices acuminate, bidentate, teeth about 0.5 mm; pedicels hispid on the margins, usually glabrous elsewhere. Pedicellate spikelets similar to the sessile spikelets. 2n = 20.
