Utricularia resupinata B.D. Greene ex Bigelow. Common name: Northeastern Bladderwort, Resupinate Bladderwort. Phenology: May-Oct. Habitat: Wet pine flatwoods, pond margins, peaty seepages, shores of natural lakes, also in artificial impoundments (presumably spread by waterfowl). Distribution: NS west to nw. WI, south (irregular and scattered in part) to FL and sw. GA; also in the Bahamas (Sorrie & LeBlond 1997), Mexico (TAB). Although "the curious gap in the North American range" [NC, SC, and VA] (Taylor 1989) is no longer strictly a gap, U. resupinata does appear to have a strangely bimodal range, with a center of distribution in ne. United States and se. Canada and a second extending from se. United States south into the West Indies and Central America.
