Meet Nepenthes bicalcarata, the Fanged Pitcher Plant.
Endemic to northwestern Borneo, this large pitcher plant is distinguished from all other Nepenthes by the two menacing fang-like spines projecting downward from its lid. These spines bear some of the largest nectaries in the plant kingdom. They likely serve to lure insects into a precarious position over the pitcher mouth, where they may lose their footing and fall into the pitcher fluid, eventually drowning.
