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 trichophora is native to Africa, where it often grows in moist, disturbed or overgrazed sites. It has been collected from disturbed sites at Canton, Maryland.
