Eriogonum hookeri is basically a species of the Intermountain Region of Utah and Nevada, just entering portions of east-central California, southeastern Oregon, southeastern Idaho, southwestern Wyoming, western Colorado, northwestern New Mexico, and northern Arizona. Populations of the species usually are scattered, with the plants rarely common and even less frequently locally weedy. P. A. Vestal (1940) stated that the Hopi boiled Eriogonum hookeri with mush for flavoring. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Eriogonum niveum is a highly variable species with a multitude of minor expressions that do not appear to have any biogeographic or taxonomic significance. The species is found mainly on the grassy plains east of the Cascade Range in southern British Columbia, west-central Idaho, northeastern Oregon, and eastern Washington. Some populations closely approach E. strictum var. proliferum, but the densely lanate leaves and semileaflike to leaflike bracts nearly always distinguish E. niveum from that taxon where their ranges overlap. It may well prove that E. niveum would be better treated as a subspecies of E. strictum, but the nomenclatural combination is not available and it is not suggested here. The plants do well in cultivation. N. J. Turner et al. (1980) reported that the snow wild buckwheat was used by the Okanagan-Colville people for colds and as a wash for cuts.
