|discussion=<p><i>Hesperostipa spartea</i> grows at elevations of 200-2600 m, primarily in the grasslands of the central plains and southern prairies of the Flora region. In its more northern locations, it tends to grow on sandy soils. The southern and western specimens from outside its primary range may represent introductions. It was once a common species, but its habitat is now intensively cultivated. It differs from <i>H. curtiseta</i> in its larger size, unevenly pubescent culm nodes, usually ciliate lower sheaths, and longer florets. Misra (1961) argued that its longer florets and awns enabled <i>H. spartea</i> to survive in drier sites than <i>H. curtiseta</i>. Native Americans used bundles of the florets for combs.</p>
