Eragrostis ciliaris
Eragrostis plana
Eragrostis ciliaris is native to the paleotropics. It is naturalized in parts of the United States, growing along roadsides, on waste sites, in xerothermic vegetation, and sometimes in saline habitats, at 0-200 m. It may be more widespread than indicated.

Eragrostis plana is native to southern Africa. It is known from two locations in the Flora region, both waste areas near sheep and cattle lots in Florence County, South Carolina.
