Discussion | Paspalum floridanum grows along the edges of forests, flatwoods, and pinewoods and in open areas. It is a frequent component of dry-mesic soils in longleaf pine-oak-grass ecosystems, and is restricted to the eastern United States.

Paspalum blodgettii grows in hammocks, low pinelands, and along roadsides in southern peninsular Florida, the Bahamas, the Greater Antilles, southeastern Mexico, and Belize. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
