Previously considered as Utricularia fimbriata Kunth, the tropical disjunct U. simulans Pilger was observed growing in western Colrer County, Florida. Though previously reported rather widely in appropriate habitats in southern Florida, the older stations have been largely decimated by drainage and urbanization. Therefore, new stations were located. The habitat is moist sandy soils with very low nutrient content, mostly bordering the Big Cypress Swamp. In such areas, the species occurred in massive clumps with flowering peak in late October, and generally in openings among stands on Pinus elliottii v. densa and Serenoa repens.
