List of Utricularia species

There are around 240 species in the genus Utricularia, belonging to the bladderwort family (Lentibulariaceae). It is the largest genus of carnivorous plants and has a worldwide distribution, being absent only from Antarctica and the oceanic islands. This genus was considered to have 250 species until Peter Taylor reduced the number to 214 in his exhaustive study, The genus Utricularia - a taxonomic monograph, published by HMSO (1989). Taylor's classification is generally accepted, though his division of the genus into two subgenera was soon seen as obsolete. Molecular genetic studies have mostly confirmed Taylor's sections with some modifications (Jobson et al., 2003), but reinstalled the division of the genus in three subgenera. This list follows the subgeneric classification sensu Müller & Borsch (2005), updated with new information in Müller et al. (2006).

Notes
  1. Lowrie et al. (2008) notes the placement of section Minutae appears, morphologically, to be closer to subgenus Bivalvaria. This was confirmed by a molecular study (Reut & Jobson, 2010)
  2. Section Pleiochasia was divided into two sections (Pleiochasia and Lasiocaules) based upon molecular data in a phylogenetic study on subgenus Polypompholyx (Jobson et al., 2017).
