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.

Eriogonum helichrysoides is limited to west-central Kansas (Ellis, Gove, Lane, Logan, Scott, and Trego counties). The plants’ dark green color and narrow leaf blades readily segregate the species from E. effusum. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
