|discussion=<p>×Elyhordeum macounii consists of hybrids between <i>Elymus trachycaulus</i> and <i>Hordeum jubatum</i>. It is quite common in western and central North America. Backcrosses to <i>E. trachycaulus</i> may have non-disarticulating rachises; they are likely to be identified as <i>E. trachycaulus</i>, falling between <i></i>subsp.<i> trachycaulus</i> and <i></i>subsp.<i> subsecundus</i>. Artificial, partially fertile octoploids were distributed to natural and experimental areas in several western states prior to 1960 (Bowden 1960); it is not known whether they have persisted.</p>
