Eriogonum lobbii is rather infrequent throughout its range. It is found in three widely scattered areas of concentration: the high mountains of northwestern California and southwestern Oregon; the southern portion of the North Coast Range of California; and the Sierra Nevada of eastern California and west-central Nevada. In the first two areas, the plants frequently are associated with serpentine soils; elsewhere the species is found almost exclusively on granitic soils and infrequently on volcanic ones. There are some morphologic differences between the Sierran plants and those of the coastal mountains, but no taxonomic separation is suggested. The species is a food plant for the intermediate dotted-blue butterfly (Euphilotes intermedia). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Eriogonum artificis is known from a single location near Frisco in Beaver County. Care must be taken not to confuse Kaye’s wild buckwheat with glabrous forms of E. spathulatum that occur nearby. The flowers of E. artificis are usually pale yellow, but occasionally plants are found with cream-colored and distinctly yellow flowers.
