|discussion=<p>Varieties 9 (6 in the flora).</p><!--
--><p><i>Eriogonum wrightii</i> 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 <i></i>var.<i> nodosum</i> complex where, at least in Mexico, one additional expression remains to be named. A clear distinction between <i></i>var.<i> subscaposum</i> and <i>E. kennedyi</i> is not possible in southern California (see discussion below). Nearly all of the varieties of <i>E. wrightii</i> are in cultivation, although the most elegant (<i></i>var.<i> olanchense</i>) has yet to be so honored.</p><!--
--><p>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 (<i></i>var.<i> wrightii</i>) as an emetic, while M. L. Zigmond (1981) stated that the Kawaiisu used the pounded seeds (probably of <i></i>var.<i> subscaposum</i>) 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).</p>
