Common Name: Orcutt's threeawn Duration: Perennial Nativity: Native Lifeform: Graminoid General: Tufted perennial, stems in small or rather large clumps mostly 30-100 cm tall, unbranched except at the base. Vegetative: Sheaths rounded or basal ones becoming flattened in age, glabrous or occasionally scabrous-pubescent, short or long hairy on the collar, ligule a dense fringe of short hairs, blades 1-3 mm broad, flat or more often involute, relatively long. Inflorescence: Panicle mostly 15-30 cm long with slender, flexuous branches, the lowermost to 15 cm long, usually widely spreading or deflexed at maturity and often bare of spikelets below the middle; branchlets and spikelets more or less appressed along the main branches; glumes glabrous or scabrous-pubescent in lines, mostly unequal, second usually 8-12 mm long, first about two-thirds as long; body of lemma minutely rugose, dark violet or blotched with violet at maturity, mostly 5-7 mm long with pubescent callus; awn column scabrous, tightly twisted, 2-4 mm long, lateral awns usually absent or minute, rarely 2 mm or more long; central awn short, delicate mostly 6-10 mm long, sharply geniculate at the apex of the awn. Ecology: Found on dry slopes in grasslands, woodlands and forest openings from 4,000-7,000 ft (1219-2134 m); flowers August-September. Notes: Considered one of the better forage species among the three awns, greens up early in the spring.  Ethnobotany: Unknown Etymology: Aristida is from the Latin arista for awn, while purpurea is Latin for purple, orcuttiana is named after Charles Russell Orcutt (1864-1929) a California botanical collector.
