distribution_en:

description_en: Genus of approximately 180 species of terrestrial, epiphytic, or free-floating aquatic annuals and perennials found worldwide in stagnant, shallow water, or growing on rainforest trees. They are insectivorous, and thrive in water that attracts mosquito larvae. Generally rootless, they have mainly submerged stems, either loosely anchored or free-floating, and thread-like or linear to rounded leaves with traps (bladders) adapted to catch and absorb insects. The flowers, solitary or in racemes, are usually borne on leafless stems above the water, and are supported by a whorl of spongy, floating leaves. Grow in an outdoor pool. In frost-prone areas, grow tender species in a warm aquarium. The hardy species may also be grown in a cold-water aquarium.
