Plants annual, tufted. Culms 5-50 cm, slender, erect. Sheaths smooth; ligules 1.5-3 mm, membranous, rounded to acute, entire; blades 2-10 cm long, 0.5-4 mm wide, flat. Panicles 0.9-8 cm long, (0.2) 0.7-1.5 cm wide, cylindrical, generally straw-colored or brown, appearing bristly; branches to 1 cm, ascending to appressed, with 1 branch at the lowest node; pedicels 0.1-0.7 mm, scabrous. Spikelets 2.6-3.6 mm. Glumes lanceolate, subequal, keels scabrous, sides smooth, apices acute; lower glumes 2.6-3.6 mm; upper glumes (2) 2.4-3.5 mm; calluses pilose on all sides, hairs to 0.5 mm, dense; lemmas (1) 1.4-1.6 mm, pilose, 5-veined, lateral-veins prolonged into awnlike teeth, outer teeth (0.8) 1-2 mm, inner teeth 0.1-0.2 (0.5) mm, awns 4.5-6 mm, arising from the lower 1/3 of the lemmas, exceeding the glumes by 2-2.5 mm; paleas absent: anthers 0.2-0.5 mm, sometimes differing in length within a floret, often remaining on the apices of the caryopses. Caryopses 1-1.3 mm; hila oval; endosperm liquid or doughy. 2n = unknown.
