A carnivorous plant distributed mainly in Southeast Asia; some species are native to the Ogasawara Islands in Japan. Leaf tips are modified into pitcher-shaped traps that store digestive fluid to capture insects.
Identification Points
- βLeaf tips modified into pitcher-shaped traps with lids
- βDigestive fluid stored inside the pitchers
- βClimbing habit, growing in bright spots in tropical forests

Evolution Notes
Nepenthaceae belongs to Caryophyllales; the modification of leaves into pitfall traps evolved independently for nitrogen and phosphorus acquisition in nutrient-poor wetland environments.
