General Taxonomy of Insectivorous Plants

The insectivorous plants are found in nine angiospermous families.

• Bromeliaceae (Brocchinia hectioides, B. reducta, Catopsis berteroniana of the Neotropics)
• Byblidaceae (Byblis gigantea, B. liniflora of Australia and New Guinea)
• Cephalotaceae (one species, Cephalotus follicularis, endemic to Australia)
• Dioncophyllaceae (Triphyophyllum peltatum of western Africa)
• Droseraceae (about 110 species; Aldrovanda, Dionaea, Drosera and another view, Drosophyllum)
• Lentibulariaceae (Genlisea, Pinguicula, Utricularia)
• Nepenthaceae (Nepenthes (another view), 70 spp. of Southeast Asia and Madagascar)
• Sarraceniaceae (Darlingtonia, Heliamphora, Sarracenia, another view)

Judging from the current placement of these families within a phylogenetic classification of dicotyledons, the insectivorous habit appears to have evolved independently numerous times.
