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 wrightii ( İngilizce )

wikipedia EN tarafından sağlandı

Eriogonum wrightii is a species of wild buckwheat known by the common names bastardsage and Wright's buckwheat. It is native to the Southwestern United States, California, and northwest Mexico, where it grows in many plant communities, such as chaparral, in rocky habitats from mountains to deserts.

Description

It is quite variable in appearance; it may be a small perennial herb 10 centimeters tall or a bushy shrub over a meter wide. There are several varieties as well. In general it has basal leaves as well as a few leaves along the stem, which are usually narrow and woolly. The inflorescence has long, straight branches which may be hairless to woolly and have flower clusters and sometimes small leaves at the nodes. The flowers are usually white to light pink.
