|discussion=<p><i>Eriogonum thornei</i> is known from a single canyon area in the New York Mountains, San Bernardino County. Shultz elevated Thorne’s wild buckwheat to species status when she proposed E. phoeniceum, here considered a variety of <i>E. microthecum</i>. <i>Eriogonum thornei</i> and <i>E. ericifolium</i> are weakly differentiated, with minimal morphologic differences, and yet they occur on different substrates and are well-removed biogeographically from each other. Thorne’s wild buckwheat is a protected plant in California.</p>
