Discussion | Paspalum praecox grows in pitcher plant bogs, wet pine flatwoods, wet savannahs, prairies, and wet streamhead ecotones. It is restricted to the United States, growing predominantly on the southeastern coastal plain. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.) |
