General Description
Perennial bunchgrass or sodgrass. Stems 20–50 cm long. Leaves: blades 1–2 mm wide, often curled. Inflorescence of 1 to 4 secund lateral divergent spikes, each 2–4.5 cm long and with 50 to 80 spikelets, each lateral rachis terminated by a spikelet, Spikelets 4–5.5 mm long, second glume essentially hairless or with clear gland-based hairs. Lemmas essentially hairless, short-awned, these disarticulating from the spikelet; rudimentary florets 1, densely hairy (Lavin in Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).
