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 acuminatum grows at the edges of lakes, ponds, rice fields, and wet roadside ditches. It is native to the Americas, with a range that extends from the southern United States to Argentina. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
