Eragrostis curvula
Eragrostis atrovirens
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 atrovirens is native to northern Africa, but it is now established in southeastern United States, where it grows along railways and roads, on beaches and in ditches, often in wet sandy soils and in association with Pinus, Taxodium, and Sabal.
