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 elliottii grows in sandy pinelands and live-oak woodlands on the coastal plain, at 0-150 m. Its range extends from the southeastern United States through the West Indies and Gulf coast of Mexico to Central and South America.
