|discussion=<p><i>Andropogon hallii</i> grows on sandhills and in sandy soil. Its range extends through the central plains into northern Mexico. It is similar to <i>A. gerardii</i>, differing primarily in its rhizomatous habit, more densely pubescent rames and pedicels, and greater drought tolerance. <i>Andropogon hallii</i> and <i>A. gerardii</i> are sympatric in some locations. The two species can hybridize and are sometimes treated as conspecific subspecies.</p>
