Nepenthes philippinensis (pronounced /nɨˈpɛnθiːz fɪˌlɪpɨˈnɛnsɪs/) is a tropical pitcher plant endemic to the Philippines. It is known from Palawan and the Calamian Islands (including Busuanga, Coron, and Culion), where it grows at 0–600 m above sea level.[1]
Nepenthes wilkiei was described by Matthew Jebb and Martin Cheek in 1998.[2] This taxon was subsequently found to be conspecific with N. philippinensis.[3][4] Jebb and Cheek suggest that N. philippinensis is more closely related to the Bornean species N. hirsuta, N. hispida, and N. macrovulgaris than it is to N. alata.[3][4]
Nepenthes philippinensis produces the most concurrent inflorescences of any species in the genus; up to 190 have been recorded on a single plant.[5]
Nepenthes philippinensis has no known natural hybrids.[5] No forms or varieties have been described.
