Description: A large and unusual species from the peat swamps of northwestern Borneo. The sturdy pitchers bear two fangs which protrude from beneath the lid, giving this plant a fearsome appearance. The purpose of these fangs is questionable, but may serve to guide nectar-seeking insects directly over the pitcher mouth where they can easily fall into the fluid below. This species plays host to a symbiotic species of ant which make their nests in the hollow tendrils and are able to swim in the pitcher fluid to retrieve dead insects.

Cultivation recommendations: Requires warmth and plenty of space for growth. Leaves can attain lengths of nearly one meter. Although plants are occasionally found in waterlogged habitats, a well-drained media is recommended in cultivation. See also: How to Grow Nepenthes
