Paspalum praecox
Paspalum lividum
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.

Paspalum lividum grows in fresh and brackish marshes and ditches. It is native from the Gulf coast of the United States southward through Mexico and Central America to Cuba and Argentina. Plants of P. modestum with pale upper florets may be mistaken for P. lividum, but will have ligules that are only 1-2.3 mm long.
Zuloaga and Morrone regard Paspalum lividum as a synonym of P. denticulatum Trin. (http://mobot.mobot.org/W3T/SearclVnwgc.html December 9, 2002).
