Chloris submutica
Chloris ciliata
Chloris submutica grows from the southwestern United States through Mexico, Guatemala, and Colombia to Venezuela. In Mexico, it is generally found between 1000-2100 m.

Chloris ciliata is a native species of grasslands from the Gulf Coast of Texas, through the Caribbean islands and Mexico to Central America, then, as a disjunct, in Argentina. Argentinean plants differ from northern plants in having long hairs associated with their basal ligules, but no other differences are known. It has been found, as an introduction, in New York.
