Plants perennial; densely cespitose. Culms 10-70 cm, erect, glabrous and smooth or scabrous just below the nodes. Ligules (0.3) 0.7-2 (2.7) mm, hyaline to membranous, entire; blades 1-15 cm long, 0.6-2.5 mm wide, scabrous. Panicles 3-25 cm long, 1-10 cm wide; branches ascending; pedicels 2-9 mm, straight or flexuous. Glumes (1.5) 1.8-2.6 (3) mm, often appearing 3-veined because of the characteristic infolding of the margins; lemmas (2) 2.3-3.5 (3.9) mm; anthers 1.2-2.1 mm, brownish. Caryopses 1.2-1.4 mm. 2n = 16.

Distribution

Utah, Ariz., Colo., N.Mex., Tex.
