|discussion=<p>Elymus canadensis var. brachystachys is widespread in the southern Great Plains from Nebraska to Mexico, where anthesis is from March to early June. It also occurs sporadically as far north as southern Canada, from British Columbia to Quebec. Plants of this variety occasionally appear introgressed from E. virginicus (p. 298), particularly E. virginicus var. jejunus, but not to the same extent as E. canadensis var. robustus.</p>
