Eragrostis lehmanniana
Eragrostis unioloides
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 unioloides is an Asian species that is now established in the southeastern United States, growing along roadsides and in disturbed ground, at 20-150 m.
