Varieties 3 (3 in the flora). Eriogonum jamesii is a nectar source for the rare Spalding dotted-blue butterfly (Euphilotes spaldingi). Eriogonum jamesii and E. arcuatum (see below) are considered “life medicines” and used ceremonially by Native Americans (C. Arnold, pers. comm.; A. B. Reagan 1929; P. A. Vestal 1952).

Eriogonum brachyanthum basically is a species of the Mojave Desert, extending northward in eastern California (Inyo, Kern, Los Angeles, Mono, Riverside, and San Bernardino counties) and along the Lahontan Trough of Nevada (Churchill, Esmeralda, Eureka, Humboldt, Lander, Lyon, Mineral, Nye, Pershing, and Washoe counties) to just north of Denio in Harney County, Oregon. It is common to abundant and even locally weedy in the northern Mojave Desert. Elsewhere it is less common and much more widely scattered. It often is found with other annual wild buckwheats forming dense patches (especially along highways) composed of several (up to seven in places) species, and care must be taken to sort them properly when making herbarium specimens.
