Nepenthes truncata (/nɨˈpɛnθz trʌŋˈkɑːtə/; from Latin: truncatus = terminating abruptly) is a tropical pitcher plant endemic to the Philippines. It is known from the islands of Dinagat, Leyte, and Mindanao.[2] The species grows at an elevation of 0–1500 m above sea level.[3] Nepenthes truncata is characterised by its heart-shaped (truncate) leaves and very large pitchers, which can reach up to 40 cm in height.

Nepenthes robcantleyi was once considered a dark, highland form of this species.[4][5]

Carnivory

On September 29, 2006, at the Botanical Gardens in Lyon, France, a Nepenthes truncata was photographed containing the decomposing corpse of a mouse. This incident is the first record of a mammal being successfully trapped in the pitchers of N. truncata. Both N. rajah[6] and N. rafflesiana[7] are known to occasionally catch small mammals in the wild.
