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.

Of conservation concern. Eriogonum eremicola is rare to infrequent, known only from the New York Butte area of the Inyo Mountains and the Telescope Peak area of the Panamint Range in Inyo County. The Bureau of Land Management considers it a “sensitive” species, and it is well protected in Death Valley National Park.
