|discussion=<p><i>Leymus cinereus</i> grows along streams, gullies, and roadsides, and in gravelly to sandy areas in sagebrush and open woodlands. It is widespread and common in western North America. <i>Leymus cinereus</i> resembles Psathyrostacbys juncea, differing in its non-disarticulating rachises, larger spikelets with more florets, and longer ligules. Spontaneous hybridization between <i>L. cinereus</i> and <i>L. triticoides</i> is known; the hybrids do not have a scientific name. The rhizomes found in some specimens may reflect introgression from <i>L. triticoides</i> through such hybrids.</p>
