Nepenthes rafflesiana upper pitchers are funnel-shaped and often bear a distinctive raised section at the front of the peristome.

The upper pitcher of a Nepenthes plant is a specialized leaf structure that serves as a unique trap for insects and small creatures. It is typically located higher on the plant and has a distinct shape, often resembling a pitcher or vase. These pitchers are designed to catch rainwater and are equipped with slippery surfaces and downward-pointing hairs that prevent trapped insects from escaping. The upper pitchers contain a fluid that helps digest the captured prey, providing the plant with additional nutrients. This adaptation allows Nepenthes to thrive in environments with nutrient-poor soil by supplementing their diet through carnivory.
