Tropical pitcher plant endemic to the Philippines
Nepenthes merrilliana (; after Elmer Drew Merrill ) is a tropical pitcher plant endemic to the Philippines . It produces some of the largest pitchers in the genus , rivalling those of N. rajah .[ 7]
The species is native to northern and central Mindanao as well as neighbouring Dinagat [ 7] and Samar .[ 8] Its presence in southern Mindanao is uncertain.[ 7] It inhabits coastal forest areas on steep slopes[ 1] at elevations of 0–1100 m above sea level .[ 9]
Nepenthes surigaoensis is closely related to N. merrilliana and was for a long time considered a heterotypic synonym of this species.[ 10] Nepenthes samar is another closely allied species.[ 11]
