Lentibulariaceae, the bladderwort family, is a family of carnivorous plants containing three genera: Genlisea, the corkscrew plants; Pinguicula, the butterworts; and Utricularia, the bladderworts.The genera Polypompholyx (two species of pink petticoats or fairy aprons) and Biovularia were formerly regarded as fourth and fifth members of this family. Biovularia has been subsumed into Utricularia, and Polypompholyx has been relegated to a subgenus of Utricularia. Placement of the family was previously in the Scrophulariales, which has been merged with Lamiales in the Angiosperm Phylogeny Group system.
