Wild populations of three bladderworts (Utricularia, Lentibulariaceae) were newly recognized in Taiwan. Utricularia heterosepala is newly recorded in Hualien, and two naturalized species, U. smithiana and U. tricolor, are found in northern Taiwan. Morphology, ecology and conservation status of these species are described. A renewed key for all Utricularia species ever recorded in Taiwan and Kinmen is also presented.
