|discussion=<p><i>Elymus ×saundersii</i> comprises hybrids between <i>E. trachycaulus</i> (p. 321) and <i>E. elymoides</i> (p. 318). Such hybrids are found throughout much of the western portion of the contiguous United States, mostly in disturbed areas. The hybrids are generally sterile and, as in all hybrids involving <i>E. elymoides</i> or <i>E. multisetus</i> (p. 318), the rachises disarticulate at maturity.</p><!--
--><p><i>Elymus ×saundersii</i> is an <i>Elymus</i> named hybrid</p><!--
--><p><i>Elymus</i> is notorious for its ability to hybridize. Most of its interspecific hybrids are partially fertile, permitting introgression between the parents. The descriptions provided below are restricted to the named interspecific hybrids. They should be treated with caution and some skepticism; some are based solely on the type specimen, because little other reliably identified material was available. Moreover, as the descriptions of the non-hybrid species indicate, many other interspecific hybrids exist.</p><!--
--><p>The parentage of all hybrids is best determined in the field. Perennial hybrids, such as those in <i>Elymus</i>, can persist in an area after one or both parents have died out, but the simplest assumption is that both are present. Interspecific hybrids of <i>Elymus</i> that have disarticulating rachises presumably have <i>E. elymoides</i> or <i>E. multisetus</i> as one of their parents.</p>
