Heliamphora exappendiculata is a marsh pitcher plant native to the Chimantá and Aprada Massifs in Bolívar state, Venezuela. Previously classified as a variety of H. heterodoxa, it was elevated to species status. The plant's pitchers feature flattened mouths that serve as landing platforms for insects, which then fall into the trap. The pitchers also collect leaf litter and organic debris, providing additional nutrients. It hybridizes with H. pulchella and H. huberi in overlapping habitats and prefers shaded environments. Populations on Chimanta and Amuri Tepui grow on permanently wet gorge walls, while others are found on summit savannahs and shrubby forests, though these are less common.

Description

Heliamphora exappendiculata, a member of the Sarraceniaceae family, is native to Venezuela. It is found in the Chimantá and Aprada Massifs in Bolívar state. The species was once considered a variety of H. heterodoxa but is now recognized as distinct. Its pitchers have flattened mouths that act as landing platforms for insects, which then fall into the trap. The structure of the pitchers also allows for the collection of leaf litter and organic debris, which may supplement the plant's nutrition, similar to H. ionasi. The species naturally hybridizes with H. pulchella and H. huberi in areas where they co-occur. It thrives in shaded habitats. On Chimanta and Amuri Tepui, it grows on the walls of gorges and ravines with permanently wet surfaces. In other regions, it is found on summit savannahs and stunted or shrubby forests, though these habitats are less frequently occupied.
