Of conservation concern. Eriogonum cinereum occurs naturally along the Pacific Coast in Los Angeles, Santa Barbara, and Ventura counties, and also on Santa Rosa Island. It is infrequently planted along highways (and is now found in San Diego County) and hybridizes with E. fasciculatum var. foliolosum. The species is the food plant of the Bernardino dotted-blue butterfly (Euphilotes bernardino). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Eriogonum trichopes is common on the Sonoran Desert and the southern portion of the Mojave Desert from southern California (Imperial, Inyo, Riverside, San Bernardino, and San Diego counties), eastward across southern Nevada (Clark, Lincoln, and Nye counties), southwestern Utah (Washington County), and Arizona (Coconino, Cochise, Gila, Graham, La Paz, Maricopa, Mohave, Pima, Pinal, Santa Cruz, Yavapai, and Yuma counties) to southern New Mexico (Cibola, Dona Ana, Grant, Hidalgo, Luna, Otero, and Valencia counties). It is also found to the south in northern Mexico (Baja California Norte, Sonora, and Chihuahua). Two related species occur in Baja California, the perennial E. scalare and the annual E. intricatum. Unlike E. trichopes, which occasionally has inflated stems, neither of those Mexican species exhibits that trait. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
