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 plicatulum grows in prairies, along forest margins, and in disturbed areas. Its range extends from the southeastern United States through the Caribbean and Mexico to Bolivia, Paraguay, and Argentina. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
