Eragrostis polytricha
Eragrostis setifolia
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 setifolia is an Australian species that was collected around the Santee Wool Combing Mill, Jamestown, Berkeley County, South Carolina, in 1958. It is not known to have spread from that location. There is no illustration of the species because it was a late addition to the treatment.
