|discussion=<p><i>Leymus innovatus</i> is a North American species that grows in open woods and forests, riverbanks, open prairies, and rocky soils, and often in sandy, gravelly, or silty soils, primarily from northern Alaska to Hudson Bay, and south into the Black Hills region of Wyoming and South Dakota. Morphologically, the two subspecies show some overlap. Bowden recognized them in part because of their difference in ploidy level.</p>
