Nepenthes robcantleyi is a tropical pitcher plant endemic to the Philippine island of Mindanao.[1] It is closely allied to N. truncata and was once considered a dark, highland form of this species.[2] Nepenthes veitchii from Borneo is also thought to be a close relative.[1]
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.[3]
The specific epithet robcantleyi honours Robert Cantley, who was involved in the plant's discovery, propagation, and introduction to cultivation.[2]
The herbarium specimen Cheek 15877 is the designated holotype and is deposited at the Royal Botanic Gardens, Kew (K) in London, England.[4] An isotype is held at the Philippine National Herbarium (PNH) in Manila, the Philippines.[4] Cheek 15877 was prepared on July 15, 2010, and originates from cultivated material that was grown from wild seed originally collected by Cantley in 1997.[4]
