|discussion=<p><i>Muhlenbergia asperifolia</i> grows in moist, often alkaline meadows, playa margins, and sandy washes, on grassy slopes, and around seeps and hot springs, at elevations of 55-3000 m. Its geographic range includes northern Mexico. <i>Muhlenbergia asperifolia</i> is morphologically similar to the southeastern <i>M. torreyana</i>, but differs in having glabrous, weakly compressed culms and more widely divergent panicle branches.</p><!--
--><p>The caryopses of <i>Muhlenbergia asperifolia</i> are frequently infected by a smut, Tilletia asperifolia Ellis & Everhart, which produces a globose body filled with blackish-brown spores.</p>
