Varieties 2 (2 in the flora). The mature reddish roots of Eriogonum alatum can be distinctively chambered. The Navajo (Diné) people consider the species to be a “life medicine” (L. C. Wyman and S. K. Harris 1951), using a mixture of shredded roots and water primarily to treat internal ailments. The species is used also as a ceremonial medicine (P. A. Vestal 1952). The Zuni use it as an emetic for stomachaches (S. Camazine and R. A. Bye 1980). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Eriogonum lemmonii is rare and localized, only infrequently being locally occasional. It is restricted to the southwestern edge of the pluvial Lahontan Lake basin of northwestern Nevada. It is found mainly in the Silver Springs and Wadsworth areas of Washoe, Churchill, and Storey counties, with outlying populations at the southern end of the Sahwave Mountains (Pershing County) and in Wilson Canyon (Lyon County). It is on the Nevada “watch list” of narrowly distributed endemic species. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
