Discussion

Chloris barbata grows in subtropical and tropical coastal regions on loams, limestone-derived soils, and along beaches. The main portion of its range lies to the south of the Flora region, through the Caribbean and the east coast of Mexico, Central America, and South America. It is a weedy species, often growing in waste areas, but also in cultivated fields.
