Plants annual; often tufted. Culms 30-60 cm, slender. Sheaths pilose-pubescent to nearly glabrous; blades 7-28 cm long, 2-9 mm wide, pilose or glabrous. Panicles 10-20 cm long, 3-9 cm wide, erect, dense; branches appressed to spreading, sometimes flexuous. Spikelets 15-20 mm, elliptic to lanceolate, more or less terete, with 3-9 florets. Glumes glabrous, acuminate; lower glumes 8-10 mm, 1-veined; upper glumes 12-16 mm, 3 (5) -veined; lemmas 11-14 mm, lanceolate to linear-lanceolate, sparsely pubescent, 5-veined, rounded over the midvein, apices acuminate, bifid, teeth 2-3 mm, usually aristate, sometimes acuminate; awns 13-20 mm, geniculate, strongly to moderately twisted in the basal portion, arising 1.5 mm or more below the lemma apices; anthers 2-2.5 mm. 2n = unknown.

Distribution

Utah, Calif., Ariz., Oreg., Nev.
