|discussion=<p><i>Leymus triticoides</i> grows in dry to moist, often saline meadows. Its range extends from southern British Columbia to Montana, south to California, Arizona, and New Mexico, but its populations are widely scattered. It is not known from Mexico. There is considerable variation within the species, but no pattern of variation suggesting the existence of infraspecific taxa is known. It is very similar to <i>L. multicaulis</i>, strains of which were initially released as <i>L. triticoides</i> by the U.S. Department of Agriculture. The most consistent differences between them appear to be in the venation of the leaf blades and the vestiture of the calluses. <i>Leymus triticoides</i> is also very similar to <i>L. simplex</i>, differing from it in the number of spikelets at the midspike nodes.</p><!--
--><p><i>Leymus triticoides</i> hybridizes with other species of <i>Leymus</i>; hybrids with <i>L. mollis</i> are called <i>L. xvancouverensis</i> (see p. 358), those with <i>L. condensatus</i> are called <i>L. xmultiflorus</i> (see p. 362). Hybrids with <i>L. cinereus</i> are known, but have not been formally named. Plants identified as <i>Elymus</i> arenicolus Scribn. & J.G. Sm. are here included in <i>L. flavescens</i>, but may represent hybrids between <i>L. triticoides</i> and <i>L. flavescens</i>.</p>
