|discussion=<p>The morphologic characteristics of <i>Stephanomeria diegensis</i> are a combination of those of <i>S. exigua</i> and <i>S. virgata</i>, and the species is thought to have evolved from genetic segregates of their hybridization (L. D. Gottlieb 1971; G. P. Gallez and Gottlieb 1982).</p>
