Eragrostis ciliaris
Eragrostis elongata
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 elongata is native to southeastern Asia and Australia, where it grows in disturbed, sandy soils at 0-50 m. It was collected once near Washington, D.C., probably as an escape from the U.S. Department of Agriculture's experimental grass garden; it has not become established in the Flora region.
