|discussion=<p><i>Muhlenbergia mexicana</i> usually grows in mesic to wet areas such as moist prairies and woodlands, stream banks, roadsides, ditch banks, lake margins, swamps, bogs, and hot springs, at elevations 50-3300 m, and is found in many different plant communities. Despite its name, <i>M. mexicana</i> grows only in Canada and the United States.</p><!--
--><p>Plants with awns 3-10 mm long belong to <i>Muhlenbergia mexicana</i> <i></i>var.<i> filiformis</i> (Torr.) Scribn., and those without an awn or with awns less than 3 mm long to <i>Muhlenbergia mexicana</i> (L.) Trin. <i></i>var.<i> mexicana</i>. Early in the flowering season, <i>M. mexicana</i> may be confused with plants of <i>M. bushii</i> in which the axillary panicles are poorly developed, but they differ in their dull internodes and the fact that the blades on the secondary branches are usually similar in length and width to those of the main branches.</p>
