The Sarraceniaceae are a family of pitcher plants, belonging to order Ericales (previously Nepenthales). The family comprises three extant genera: Sarracenia (North American pitcher plants), Darlingtonia (the cobra lily or California pitcher plant), and Heliamphora (sun pitchers). The extinct Archaeamphora longicervia may also belong to this family. The first two are native to North America while Heliamphora is native to South America. All three are carnivorous plants that lure insects with nectar and use their elongated, tube-shaped leaves filled with water and digestive enzymes (or bacteria in the case of Darlingtonia) to catch and consume them. Many species also use downward-pointing hairs and waxy secretions to make it difficult for insects to escape.
