Eragrostis polytricha
Eragrostis amabilis
Eragrostis polytricha grows in sandy and rocky areas, at 0-30 m, usually in open pinelands. It is native to Florida but its primary range lies to the south of the Flora region, from southern Mexico through Central America to Venezuela, Chile, and Argentina.

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.
