Eragrostis lehmanniana
Eragrostis cumingii
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 cumingii is native to southeast Asia and Australia. Within the Flora region, it has become established in Florida, growing in waste places and along roadsides in sandy or gravelly soils, at 0-150 m.
