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.) |
Eriogonum capillare is known from southeastern Arizona (Gila, Graham, Greenlee, and Pima counties) and extreme southwestern New Mexico, where it is rare in northwestern Hidalgo County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
