Nepenthes merrilliana

Nepenthes merrilliana (/nɪˈpɛnθiːz mɛˌrɪliˈɑːnə/; 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]

Scientific classification
Kingdom: Plantae
Clade: Tracheophytes
Clade: Angiosperms
Clade: Eudicots
Order: Caryophyllales
Family: Nepenthaceae
Genus: Nepenthes
Species:
N. merrilliana
Binomial name
Nepenthes merrilliana
Synonyms

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]
