Eragrostis curvula
Eragrostis swallenii
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 swallenii grows in sandy sites along coastal grasslands and roadsides, often with Andropogon and Spartina, at 30-150 m. Its range extends around the Gulf coast from Texas to Mexico.
