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.

Eriogonum collinum is infrequent to locally common in the Lahontan Basin region of the Intermountain West in northeastern California (Lassen and Modoc counties), south-central Oregon (Lake County), and northwestern Nevada (Douglas, Humboldt, Lyon, Pershing, Storey, and Washoe counties).
