|discussion=<p><i>Bouteloua curtipendula</i> is a common, often dominant or co-dominant species in open grasslands and wetlands of the drier portions of the central grasslands of North America. It is highly regarded as a forage species and is also an attractive ornamental. Its range extends from the Flora region through Mexico and Central America to western South America.</p><!--
--><p>As the range of chromosome numbers suggests, <i>B. curtipendula</i> is an apomictic species. There are three varieties. Two of the three grow in the Flora region; the third, <i>B. curtipendula</i> <i></i>var.<i> tenuis</i> Gould & Kapadia, is endemic to Mexico.</p>
