|discussion=<p>Bowden (1967) suggested that ×Elyleymus hirtiflorus consisted of hybrids between <i>Elymus trachycaulus</i> and <i>Leymus innovatus</i>, and included in it plants from British Columbia. The name, however, is based on collections from the banks of the Green River, Wyoming, where neither putative parent grows. The more likely parents are <i>E. lanceolatus</i> and <i>L. simplex</i>. Admittedly, the short anthers argue for <i>E. trachycaulus</i> rather than <i>E. lanceolatus</i> as the <i>Elymus</i> parent. The Canadian specimens are here treated as belonging to ×Elyleymus ontariensis, a name that Bowden treated as a synonym of ×Elyleymus hirtiflorus.</p>
