Eragrostis curvula
Eragrostis obtusiflora
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 obtusiflora is native to the southwestern United States and Mexico. It grows in dry or wet alkali flats, often in association with Distichlis and Sarcobatus, at 900-1400 m.
