Eriogonum viridescens is infrequent in the Inner Coast and the Transverse ranges (Fresno, Kern, Kings, Los Angeles, Merced, Monterey, Riverside, San Benito, western San Bernardino, San Luis Obispo, Santa Barbara, and Ventura counties). Unlike those of the more widespread E. maculatum, the outer tepals of E. viridescens are swollen apically, rather than basally. A collection made at Crystal Springs in the Coso Mountains of Inyo County (Coville & Funston 909, DS, US) probably is accurately labeled but the location remains to be confirmed by modern collections.

Of conservation concern. Eriogonum mortonianum is restricted to a series of low, gypsophilous hills southwest of Fredonia, Mohave County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
