Discussion

Eragrostis curvula is native to southern Africa. It is often used for reclamation because it provides good ground cover but, once introduced, it easily escapes. In the Flora region, it grows on rocky slopes, at the margins of woods, along roadsides, and in waste ground, at 20-2400 m, usually in pine-oak woodlands, and yellow pine and mixed hardwood forests.

Eragrostis scaligera is known from Lee and Collier counties, Florida, where it grows in sandy areas in the coastal scrub zone and along adjacent roadsides, at 0-10 m. It is native to French Guiana and Brazil.
