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 siskiyouense is restricted to the ridge system that extends from the Scott Mountain area to the Mt. Eddy region of Siskiyou and Trinity counties. The vast majority of individuals in a population have a single involucre atop each flowering stem, but at lower elevations and in somewhat more protected sites the inflorescence may be umbellate. The Siskiyou wild buckwheat does well in cultivation if its soil requirements are fulfilled. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
