Discussion | Paspalum scrobiculatium is native to India. It has been found growing in widely scattered disturbed areas of the southeastern United States, possibly as an escape from cultivation. It is grown as a cereal (Kodo) in India. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.
