Varieties 9 (6 in the flora). Eriogonum wrightii is subdivided into several varieties most of which are distinct, although a few have rather indistinct boundaries. Some of the variation has yet to be fully resolved, especially in the var. nodosum complex where, at least in Mexico, one additional expression remains to be named. A clear distinction between var. subscaposum and E. kennedyi is not possible in southern California (see discussion below). Nearly all of the varieties of E. wrightii are in cultivation, although the most elegant (var. olanchense) has yet to be so honored. Few ethnobotanical uses of bastard-sage are reported in the literature. L. C. Wyman and S. K. Harris (1951) noted that the Kayenta Navajo use it (var. wrightii) as an emetic, while M. L. Zigmond (1981) stated that the Kawaiisu used the pounded seeds (probably of var. subscaposum) in a beverage or as a dry meal. Members of the species are food plants for the rare Rita dotted-blue butterfly (Euphilotes rita), the Pacific dotted-blue (E. enoptes), the veined blue (Plebeius neurona), and the Mormon metalmark (Apodemia mormo mormo).

Eriogonum tripodum occurs in widely scattered locations on the inner coast ranges (Colusa, Lake, and Tehama counties) and along the western foothills of the Sierra Nevada (Amador, El Dorado, Mariposa, Placer, and Tuolumne counties). These subshrubs would make an impressive addition to the garden. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
