Eragrostis lehmanniana
Eragrostis elliottii
Eragrostis lehmanniana is native to southern Africa, where it grows in sandy, savannah habitats. It was introduced for erosion control in the southern United States, where it often displaces native species. In the Flora region, it grows in sandy flats, along roadsides, on calcareous slopes, and in disturbed areas, at 200-1830 m. It is commonly found in association with Larrea tridentata, Opuntia, Quercus, Juniperus, and Bouteloua gracilis.

Eragrostis elliottii grows in sandy pinelands and live-oak woodlands on the coastal plain, at 0-150 m. Its range extends from the southeastern United States through the West Indies and Gulf coast of Mexico to Central and South America.
