General Description
Bunchgrass. Stems 20–60 cm. Leaves: blades 1–5 mm wide, flat to folded. Inflorescence 4–14 cm long, the erect rachis readily disarticulating at maturity. Spikelets usually 2 per node (1 to 3), 11–14 mm long; glumes gradually tapering from the base to a narrow acute tip, often bifid, rarely trifid, distinctly 1- to 2-veined, imperceptibly tapering into 1 or 2 awns that are 2–11 cm long. Lemmas mostly 2 to 6 per spikelet, hairless to hairy, tapering into an awn 2–10 cm long (Lavin in
Lesica et al. 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).
