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 cumingii is native to southeast Asia and Australia. Within the Flora region, it has become established in Florida, growing in waste places and along roadsides in sandy or gravelly soils, at 0-150 m.
