This robust sedge is widespread in swamps and marshes across eastern North America, but occurs mostly in coastal and lacustrine regions. It was recently collected by K. Feeman in the Hog Hollow area of BATH (MDKY; Clark et al. 2005). It has also been reported from Ky. by Small (1903), Gleason (1952) and others, presumably based on an old coll. (but none found at NY).
