General Description
Warm season, annual bunchgrass. Stems 10–120 cm long, few- to many-bunched, usually sprawling to ascending. Leaves: blades 5–25 mm wide, flat and lax; ligule absent or represented by a pigmented rim; sheaths with overlapping margins. Inflorescence a contracted secund panicle 5–22 cm long. Spikelets 2.5–4.5 mm long (excluding awns) with one fertile floret; first glume 1–1.5 mm long, second glume 2.5–4.5 mm long, gradually tapering to a sharp-pointed tip, with stiff coarse hairs along veins. Lemmas: sterile lemma like second glume and with an awn 0.5–20 mm long; fertile lemma awnless with an acute apex globe-like. Disarticulation above the glumes; unit of dispersal the floret (Lavin in Lesica et al. 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).
