Eriogonum panamintense is widely scattered in the desert ranges from the southern tip of the White Mountains in Inyo County to the New York Mountains of San Bernardino County, California, eastward across Nevada in the Magruder and Silver Peak (Esmeralda County), Grapevine (Nye County), and Spring (Charleston) mountains (Clark County) of Nevada, on the Hualapai Mountains south of Kingman, and on Mt. Bangs south of Littlefield, Mohave County, Arizona. The Panamint Mountain wild buckwheat typically grows at elevations in California higher than does E. rupinum, but in Nevada their elevation ranges overlap, as in the Magruder Mountains and near Westgard Pass in the White Mountains.

Eriogonum argillosum is rare to locally infrequent in coastal central California. It was last seen in Santa Clara County in 1895 and now is almost certainly extirpated there. Otherwise, it is found in the San Benito River Canyon (San Benito County) area and east of San Lucas (Monterey County). This is the most distinct of the five species in the E. eastwoodianum complex.
