--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>cespitose, not rhizomatous. <b>Culms</b> 15-65 cm, erect to ascending, usually puberulent; nodes 4-6, mostly concealed, glabrous. <b>Leaves</b> evenly distributed; sheaths glabrous or white-villous; auricles usually present, 0.5-1.5 mm; ligules to 1 mm, truncate, entire or lacerate; blades 1.5-4(5) mm wide, often ascending and involute, adaxial surfaces scabrous, pilose, or villous. <b>Spikes</b> 5-20 cm long, 5-15 cm wide, erect, sometimes partially enclosed at the base, with 2 spikelets per node, rarely with 3-4 at some nodes; internodes 3-5(8) mm long, 0.1-0.3 mm thick at the thinnest sections, glabrous beneath the spikelets. <b>Spikelets</b> 10-15 mm, divergent, with 2-4 florets, lowest florets sterile and glumelike in 1 or both spikelets at each node; disarticulation initially at the rachis nodes, subsequently beneath each floret. <b>Glumes</b> subequal, (10)30-100 mm including the awns, the bases indurate and glabrous, glume bodies (2)5-10 mm long, 1-2 mm wide, setaceous, 2-3-veined, margins firm, awns (8)25-90 mm, each split into 3-9 unequal divisions, scabrous, flexuous to outcurving from near the glume bases at maturity; fertile lemmas 8-10 mm, smooth or scabrous near the apices, 2 lateral veins extending into bristles to 10 mm, awns (10)20-110 mm long, about 0.2 mm wide at the base, divergent to arcuate; paleas 7-9 mm, veins usually extending into about 1 mm bristles, apices acute to truncate; anthers 1-2 mm. <b>Anthesis</b> from late May to June. <b>2n</b> = 28.</span><!--

|discussion=<p><i>Elymus multisetus</i> grows in dry, often rocky, open woods and thickets on slopes and plains, from central Washington and Idaho to southern California, Colorado, and northwestern Arizona, and from sea level to 2000 m. It has also been reported from Baja California, Mexico. It usually grows in less arid habitats than <i>E. elymoides </i>subsp.<i> elymoides</i> (p. 319), but the two taxa are sometimes sympatric.</p><!--
--><p>Wilson (1963) reported a wide belt of introgression between <i>Elymus multisetus</i> and <i>E. elymoides </i>subsp.<i> elymoides</i> from southeastern California to southern <i>Nevada</i>, but not in other areas where they are sympatric. There are also probable hybrids with <i>E. glaucus</i> (p. 306) and <i>Pseudoroegneria spicata</i> (p. 281).</p>
