Perennial, with numerous scaly rhizomes; culms erect or sometimes spreading, scabrouspuberulent below the nodes and panicles, 50-100 cm. tall; sheaths smooth or slightly scabrous, keeled; ligule 1 mm. long, membranaceous, short-ciliate; blades flat or loosely involute, scabrous, 5-15 cm. long, mostly less than 10 cm., 2-6 mm. wide; panicles narrow, spikelike, usually more or less lobed or interrupted, grayish, silky, often purple-tinged, 7—15 cm. long; glumes thin, narrow, acuminate, ciliate-scabrous on the keels, 3-4 mm. long; lemma 3 mm. long, tapering into a capillary awn 4-8 mm. long, the hairs at base of floret copious, nearly as long as the body of the lemma.
Type locality: California, on the Colorado of the West (Gambel).
