Eriogonum saxatile is found mainly in arid mountains of California (Fresno, Inyo, Kern, Los Angeles, Mono, Monterey, Riverside, San Benito, San Bernardino, Santa Barbara, Tulare, and Ventura counties) and Nevada (Esmeralda and western Nye counties). The plants vary considerably as to robustness, degree of branching, and sprawl of the caudex. The size and position of the leaves also vary, as does the density of tomentum on the blades. Flower color varies from white to rose or yellowish, but the deep yellow of E. crocatum is never seen in E. saxatile. The species is frequently cultivated and is an excellent plant for the rock garden. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Of conservation concern. Eriogonum mohavense is typically local and infrequent, and only rarely locally common. It is restricted to the northwestern corner of the Mojave Desert in southeastern Kern, northeastern Los Angeles, and northwestern San Bernardino counties. It occurs also just inside Inyo County. An 1882 C. C. Parry collection (NY) supposedly from San Diego is discounted as to location. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
