|discussion=<p><i>Muhlenbergia cuspidata</i> grows in dry, gravelly prairies, on gentle rocky slopes, rocky limestone outcrops, and in sandy drainages, at elevations of 300-1400 m, primarily in the central portion of the flora region. It flowers from June to October.</p><!--
--><p><i>Muhlenbergia cuspidata</i> is often confused with M. ricbardsonis, but that species has rhizomes and longer ligules. Morden and Hatch (1984) found cleistogamous panicles in the lower sheaths of a plant from Benton County, Oklahoma.</p>
