Nepenthes alata
Nepenthes alata ( /nɨˈpɛnθiːz əˈlɑːtə/; Latin: alatus "winged") is a tropical pitcher plant endemic to the Philippines. It is found on all the major islands of the archipelago, with the possible exception of Palawan.[5] It is one of the easiest and most popular Nepenthes species in cultivation.
The species exhibits extraordinary variation throughout its range. The population of N. alata from Mount Guisguis, Zambales, is particularly diverse in terms of morphology, with four distinct variants present on the mountain's upper slopes.[6][7]
Nepenthes alata occurs in mossy forest at elevations ranging from 800 to 2,400 m.[8]
Taxonomy
Nepenthes alata is closely related to several other species, including N. copelandii, N. mindanaoensis, N. philippinensis, and N. saranganiensis. Nepenthes eustachya from Sumatra was once considered a form of N. alata, but this was based on a misinterpretation of type specimens; these two species do not seem directly related to each other.
