|discussion=<p><i>Hesperostipa curtiseta</i> grows on light to clay loams in the prairies and northern portion of the central plains and northern intermontane grasslands, at elevations from 750-2050 m, extending primarily from British Columbia to Manitoba and North Dakota. It resembles <i>H. comata </i>subsp.<i> intermedia</i>, but differs in having unevenly pubescent lemmas and non-lacerate ligules. It is also very similar to <i>H. spartea</i>, differing in its smaller size, usually glabrous or evenly pubescent culm nodes, usually glabrous sheaths, and shorter florets. Misra (1961) argued that its shorter florets and awns restrict <i>H. curtiseta</i> to more mesic sites than <i>H. spartea</i>.</p>
