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 hartwegianum grows in wet prairies, ditches, and swales from southern Texas through Mexico and Central America to Paraguay and Argentina. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
