General Description
Cool season, annual bunchgrass. Stems 25–50 cm. Leaves: blades 2–5 mm wide, flat and lax; sheaths with overlapping margins; ligule membranous. Inflorescence a 2-sided but cylindrical spike 5–15 cm long. Spikelets 8–14 mm long, one per node, partially to completely embedded within the rachis, usually comprising several florets; glumes broad and asymmetrical, usually awned by extension of the eccentric midrib, especially on the distal-most spikelets. Lemmas similar to glumes, awnless to awned especially on the distal-most spikelets; palea well developed. Disarticulation below the glumes; unit of dispersal the spikelet and internode of the adjacent inflorescence rachis (Lavin in Lesica et al. 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).
