|discussion=<p><i>Achnatherum nelsonii </i>subsp.<i> dorei</i> grows from the southern Yukon Territory to California and Wyoming. In regions where both subspecies grow, <i></i>subsp.<i> dorei</i> is at higher elevations than <i></i>subsp.<i> nelsonii</i>. It differs from A. rohustum in the sparsely hairy collars of its flag leaves.</p><!--
--><p>Reports of <i>Achnatherum nelsonii </i>subsp.<i> dorei</i> (identified as <i>Stipa</i> columbiana Macoun by many authors) from New Mexico and Arizona are probably based on <i>A. perplexum</i>, which differs in having sparse, narrow inflorescences and slightly recurved glumes. The two also differ in flowering time, <i>A. nelsonii </i>subsp.<i> dorei</i> flowering in late spring to early summer and <i>A. perplexum</i> in the fall. <i>Achnatherum nelsonii </i>subsp.<i> nelsonii</i> is present in New Mexico. Scagel and Maze (1984) concluded that putative hybrids between <i>A. nelsonii </i>subsp.<i> dorei</i> and <i>A. richardsonii</i> were merely large plants of <i>A. nelsonii </i>subsp.<i> dorei</i> that varied in the direction of <i>A. richardsonii</i>.</p>
