Eragrostis bahiensis
Eragrostis elongata
Eragrostis bahiensis grows in sandy soils near river banks, lake shores, and roadsides, at 0-200 m. Its range extends south from the Gulf Coast of the United States through Mexico to Peru, Bolivia, Paraguay, and Argentina.

Eragrostis elongata is native to southeastern Asia and Australia, where it grows in disturbed, sandy soils at 0-50 m. It was collected once near Washington, D.C., probably as an escape from the U.S. Department of Agriculture's experimental grass garden; it has not become established in the Flora region.
