Eriogonum incanum is common throughout the central and southern Sierra Nevada of California (Alpine, El Dorado, Fresno, Inyo, Madera, Mariposa, Nevada, Tulare, and Tuolumne counties) and extreme west-central Nevada (Carson City, Douglas, and Washoe counties). It is a food plant for the green hairstreak butterfly (Callophrys lemberti), the Pacific dotted-blue (Euphilotes enoptes), and the gorgon copper (Gaeides gorgon). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Eriogonum gracilipes is generally found with Great Basin bristlecone pine (Pinus longaeva D. K. Bailey) and foxtail pine (Pinus balfouriana S. Watson) in the higher elevations of the White Mountains and on the eastern edge of the Sierra Nevada immediately to the west. The White Mountains wild buckwheat is restricted to Mono and Inyo counties, California, and just enters Esmeralda County in Nevada. It is occasionally seen in cultivation.
