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