Sarraceniaceae is a family of carnivorous plants that includes the genera Sarracenia, Darlingtonia, and Heliamphora. These plants are characterized by their passive pitcher-shaped traps, which they use to capture insects as a source of nutrients.

* Sarracenia species, also known as North American pitcher plants, have tubular or funnel-shaped leaves that trap insects in a pool of water at the bottom. The walls of the trap are slippery and often have downward-pointing hairs that prevent the prey from escaping.
* Darlingtonia californica, also known as the cobra lily, has a unique hooded pitcher shape with a forked "tongue" that attracts and traps insects. The lid of the pitcher is perforated, allowing rainwater to enter and drown the prey.
* Heliamphora species, also known as sun pitchers or marsh pitcher plants, are found in South America and have tall, slender pitchers with a wide mouth that trap insects on a slippery surface. The traps contain a digestive fluid that helps break down the captured prey.

Sarraceniaceae plants are native to North and South America and are found in wet, nutrient-poor habitats where they have adapted to supplement their diet with insects.
