Eragrostis ciliaris
Eragrostis amabilis
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 amabilis is native to the Eastern Hemisphere. It is now naturalized in the southeastern United States, growing in open areas such as cultivated fields, forest margins, and roadsides at 0-200 m.
