General Description
Cool season annual bunchgrass. Stems erect to somewhat spreading, 15–30 cm. Leaves: blades flat to inrolled, ascending, 2–6 mm wide; sheaths with overlapping margins; ligule membranous. Inflorescence 1–2 cm long, a bilateral terminal spike with a continuous rachis. Spikelets one per node, 8–12 mm long with several florets very crowded and diverging at wide angles (40–80°), the internodes 1/10 - 1/8 the length of the spikelets; glumes smaller than lemmas; glumes and lemmas becoming hardened or bony in texture at maturity. Lemmas tapering to an awn-tip; palea enclosed by lemma. Disarticulation below the glumes; unit of dispersal the burr-like spike of spikelets (Lavin in Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).
