Bladderwort family
Lentibulariaceae
タヌキモ科
A carnivorous plant family including Utricularia, Pinguicula, and Genlisea. About 3 genera and 350 species are known, mainly growing in wetlands, aquatic habitats, and on rock faces. Utricularia species use small bladder traps to capture aquatic microorganisms.
Key Characteristics
- ●Carnivorous plants (prey captured via bladder traps or sticky leaves)
- ●Utricularia has underwater bladder traps
- ●Pinguicula has sticky (adhesive) leaves
- ●Corolla sympetalous, bilabiate, often with a spur
- ●Grows in nutrient-poor environments (wetlands, rock faces)
