Eragrostis lehmanniana
Eragrostis reptans
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 reptans grows in wet sand, gravel, and clay soils along rivers and lake margins from the United States to northern Mexico, at 0-400 m, frequently with Cynodon dactylon and Heliotropium. It flowers from April through November.
