Eragrostis lehmanniana
Eragrostis superba
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 superba is native to Africa, where it is grown for hay, being fairly palatable and drought resistant. It is also used for erosion control and revegetation. In the Flora region, it grows on rocky slopes, in sandy flats, and along roadsides, at 480-1650 m, often with Acacia, Prosopsis, Fouquieria splendens, Juniperus, and Quercus. The English name is an appropriate description of the leaf blades.
