Nepenthes bicalcarata ( /nɨˈpɛnθiːz baɪˌkælkəˈrɑːtə/ or /bɪˌkælkəˈreɪtə/; Latin: bi "two", calcaratus "spur"), also known as the Fanged Pitcher-Plant, is a tropical pitcher plant endemic to northwestern Borneo. It is a myrmecophyte noted for its mutualistic association with a species of ant, Camponotus schmitzi. As an ant-fed plant it lacks many of the features that characterise the carnivorous syndrome in Nepenthes, including viscoelastic and highly acidic pitcher fluid, the waxy zone of the pitcher interior, and possibly even functional digestive enzymes.
