Nepenthes mindanaoensis

Nepenthes mindanaoensis (; "from Mindanao") is a tropical pitcher plant native to the Philippine islands of Mindanao and Dinagat.
"Nepenthes mindanaoensis" belongs to the informal ""N. alata" group", which also includes "N. alata", "N. ceciliae", "N. copelandii", "N. extincta", "N. graciliflora", "N. hamiguitanensis", "N. kitanglad", "N. kurata", "N. leyte", "N. negros", "N. ramos", "N. saranganiensis", and "N. ultra". These species are united by a number of morphological characters, including winged petioles, lids with basal ridges on the lower surface (often elaborated into appendages), and upper pitchers that are usually broadest near the base.
"Nepenthes alata" var. "ecristata"—described by John Muirhead Macfarlane in his 1908 monograph, "Nepenthaceae"—was briefly considered a synonym of "N. mindanaoensis", then regarded as a species in its own right ("N. kurata"), before that species was synonymised with "N. ramos".
Natural hybrids.
Certain plants from Mount Hamiguitan may represent crosses between "N. justinae" (previously identified as "N. mindanaoensis") and "N. hamiguitanensis", "N. micramphora", and "N. peltata".
