Genlisea /dʒɛnlᵻˈsiːə/ is a genus of carnivorous plants also known as corkscrew plants. The 30 or so species grow in wet terrestrial to semi-aquatic environments distributed throughout Africa and Central and South America. The plants use highly modified underground leaves to attract, trap and digest minute microfauna, particularly protozoans. Although suggested a century earlier by Charles Darwin, carnivory in the genus was not proven until 1998. The generic name Genlisea honors the late Stéphanie Félicité Ducrest de St-Albin, comtesse de Genlis, a French writer and educator.
