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).

Eriogonum reniforme is infrequent to locally common throughout its range on the Mojave and Sonoran deserts in Arizona, southeastern California, and southern Nevada, where it extends northward along the Lahontan Trough onto the cold desert of the Great Basin. It is disjunct in the Tucson Mountains of Maricopa County, Arizona, and while specimens have not been collected there since 1906 (Thornber 5886, CAS, MO), the species recently was found north of Wickenburg (Welnick s.n., undated, ASU). It just enters Mexico, where it is rare. Eriogonum reniforme is a food plant for the rare Mojave dotted-blue butterfly (Euphilotes mojave). The small blue (Philotiella speciosa) also feeds on these plants. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
