Eriogonum wetherillii is a species of the Colorado Plateau in northern Arizona (Apache, Coconino, and Navajo counties), southwestern Colorado (Montezuma County), northwestern New Mexico (San Juan County), and southeastern Utah (Emery, Garfield, Grand, Kane, San Juan, eastern Sevier, and Wayne counties). It typically is locally common, especially on sandy soils, but only rarely weedy. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Eriogonum libertini is encountered infrequently in the Dubakella and Tedoc mountains area of Tehama and Trinity counties in northwestern California. It is closely related to E. ternatum, found to the north. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
