Eragrostis lehmanniana
Eragrostis intermedia
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 intermedia grows in clay, sandy, and rocky soils, often in disturbed sites, at 0-1850 m. Its range extends from the United States through Mexico and Central America to South America. Eragrostis intermedia is similar to the more widespread E. lugens, but differs from that species in having wider spikelets, longer lemmas, and caryopses with a prominent adaxial groove.
