| • | See text The genus Sarracenia contains eight (or arguably up to thirteen) species of North American pitcher plants. The genus belongs to the family Sarraceniaceae, which also contains the closely allied genera Darlingtonia and Heliamphora. Sarracenia are carnivorous plants indigenous to the eastern seaboard of the United States with most species occurring in the south-east (only S. purpurea occurs in cold-temperate regions). The plant's leaves form tall lidded pitchers, which have evolved to trap insects, and which produce enzymes to digest their prey. In at least S. flava, an alkaloid drug, coniine, which is narcotic to insects, has been discovered in the plant's nectar-like secretions. In common with many carnivorous plants, Sarracenia usually inhabit permanently wet, low pH, regions whose nutrients, particularly nitrate, are continuously washed away by water or destroyed by acidity. They consequently gain a competitive advantage from the substances and minerals they extract from their animal prey. Source: [wikipedia: sarracenia] |
