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.) |
Varieties 3 (3 in the flora). Eriogonum compositum is one of the more attractive members of the genus and does well in cultivation. The three varieties are only weakly differentiated, and both var. lancifolium and var. leianthum merge with var. compositum. The butterfly Euphilotes enoptes is a pollinator of this species. The Okanagan-Colville Indians of British Columbia and Washington used plants of Eriogonum compositum as a cold remedy, an antidiarrheal, and a wash for infected cuts. Not surprisingly, children used the hollow, often slightly inflated stems as a toy (N. J. Turner et al. 1980). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
