Eragrostis polytricha
Eragrostis elliottii
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.
