Eriogonum dasyanthemum is common to locally abundant in the North Coast Ranges (Colusa, Glenn, Lake, Mendocino, Napa, Shasta, Solano, Tehama, Trinity, and Yolo counties). A single collection apparently made at Mendocino along the Pacific Ocean in Mendocino County (Brown 942, Aug 1898, B, BKL, F, GH, IND, MO, RM) requires modern confirmation. Jepson 8962 (JEPS, UTC) supposedly was gathered “above Venado” in Colusa County, but Venado is a small town in Sonoma County. The densely pubescent flowers easily distinguish this species.

Of conservation concern. Eriogonum concinnum is locally common on the mesas of the U.S. Department of Energy’s Nevada Test Site east and north of Beatty, Nye County. Although the area is subject to considerable habitat destruction, the species seems to be surviving and is neither threatened nor endangered, although it is properly considered a “sensitive” species given its limited range and the potential for more profound habitat destruction in the area.
