Genlisea tuberosa is a carnivorous species in the genus Genlisea (family Lentibulariaceae) that is endemic to Brazil and found only in campos rupestres vegetation. It has pale bundles of root-like organs under ground that attract, trap, and digest protozoans. These organs are subterranean leaves, which lack chlorophyll. This species is unique in the genus in its formation of tubers. As of 2014, Genlisea tuberosa has the smallest known genome of any flowering plant.
