About

Nepenthes robcantleyi, or Robert Cantley's pitcher plant, is a tropical pitcher plant endemic to the Philippine island of Mindanao. It is closely allied to N. truncata and was once considered a dark, highland form of this species. Nepenthes veitchii from Borneo is also thought to be a close relative.

The pitchers of N. robcantleyi are exceptionally large, reaching 40 cm in length by 10 cm in width. The inflorescence, at up to 2.5 m long, is the tallest among known Nepenthes species. The plant itself does not grow very tall, however, and is not known to climb.

Where it grows

Nepenthes robcantleyi is known with certainty only from the single location in Mindanao, the Philippines, where it was observed in 1997. This location has not been disclosed for conservation reasons.
