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 ternatum is infrequently encountered in the Coast Ranges of southwestern Oregon (Curry and Josephine counties) and adjacent northwestern California (Del Norte and western Siskiyou counties). A collection from “Dodkin’s Lake” in the Mt. Eddy area of Siskiyou County (Bracelin 455, IND) remains to be confirmed, as this is well to the east of other populations. Some workers have confused this species with E. umbellatum (especially var. humistratum). No doubt the poor representation of this species in herbaria is due at least in part to collectors having assumed that it is some variant of the much more common E. umbellatum.
