    Rhynchospora inundata is commonly found growing in bogs, marshes, wet flatwoods, cypres swamps and lake and pond margins nearly throughout Florida (Wunderlin, 2003). This colony-forming species is one of the largest of the beakrushes, and might easily be confused with Rhynchospora corniculata. Its seeds are eaten by ducks.
