Eriogonum covilleanum is encountered infrequently in the Inner Coast Ranges of central and southwestern California (Fresno, Kern, Merced, Monterey, San Benito, San Luis Obispo, Santa Barbara, Santa Clara, Stanislaus, and Ventura counties). On occasion it can be locally common but is never abundant or weedy. It is often found growing with other annual wild buckwheats, and care must be taken to sort the species. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Eriogonum vestitum is restricted to the Idria region of San Benito County, the Silver Creek Canyon and Mercey Hot Springs areas of Fresno County, and the Los Banos Hills in Merced County. It is closely related to E. eastwoodianum. Some individuals mimic E. gracile, and a clear distinction is not always possible with immature specimens.
