DESCRIPTION: Terrestrial perennial tufted graminoid (abunchgrass (clumpgrass) with decumbent, geniculate, ascending and/or erect culms 8 to 30 inches in height); the foliage is greencuring to straw; the flowers may be brownish-red, pale green, green, orange or reddish; the anthers are pink or white; floweringgenerally takes place between late July and late September (additional records: one for early March, one for mid-May, one forlate May, one for late October and one for mid-November). HABITAT: Within the range of this species it has been reportedfrom mountains; rocky-gravelly mountainsides; gravelly and sandy mesas; along canyons; sandy canyon bottoms; rocky androcky-gravelly and gravelly-loamy foothills; rocky and rocky-sandy hills; rocky, gravelly and gravelly-sandy-loamy hillsides;rocky, rocky-gravelly, gravelly, sandy, sandy-loamy, sandy-clayey and clayey slopes; rocky alluvial fans; gravelly and sandybajadas; prairies; along rocky, cobbly and sandy plains; bouldery-sandy, gravelly, gravelly-loamy and sandy flats; basins;gravelly-loamy valley floors; valley bottoms; along gravelly and sandy roadsides; sandy draws; sandy bottoms of gulches;streambeds; sandy riverbeds; along washes; rocky drainages; within drainages; swales; edges of washes; along margins ofciénegas; benches; terraces; sandy floodplains; mesquite bosques; riparian areas, and disturbed areas growing in dry boulderysandy,rocky, rocky-gravelly, rocky-sandy, cobbly, gravelly and sandy ground; rocky-clayey loam, gravelly loam, gravelly-sandyloam, gravelly-clayey loam, sandy loam and sandy-clayey loam ground, and sandy clay and clay ground, occurring from 300 to5,700 feet in elevation in the forest, woodland, scrub, grassland, desertscrub and wetland ecological formations. NOTES: Thisshort-lived perennial may be an attractive component of a restored native habitat, it has been described as being hardy anddrought-resistant. Rothrock Grama (perennial) may be confused with the annual Sixweeks Grama (Bouteloua barbata). theMasked Bobwhite (Colinus virginianus subsp. ridgwayi) feeds on the seeds of the Rothrock Grama.

NOTES: Thisplant may be an attractive component of a restored native habitat, it is reported to be drought-resistant; it may form patches orrings, and it is sometimes mistaken for an Aristida spp. because of the three-awned spikelets.
