General Description
Rhizomatous or bunched. Stems few to extensively bunched, 0.5–1.5 m. Leaves: blades 4–12 mm wide, firm, flat or rolled upon drying, leaf sheaths often with ciliate margins. Inflorescence (6–)12–30 cm long, rachis continuous, thick and somewhat concave on the side toward the spikelet, the internodes 10 or more mm long. Spikelets (10–)14–32 mm long, appressed to the main rachis, florets mostly 6 to 12 per spikelet, glumes shorter than florets, thick and blunt or notched, rarely pointed. Lemmas blunt to pointed, sometimes with a minute awn (Lavin in Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).
