Nepenthes cornuta is a tropical pitcher plant native to the Philippines. It is known only from the Pantaron Mountain Range of central Mindanao, where it grows terrestrially on ultramafic soils at around 1000 m above sea level. This species is most closely allied to N. ceciliae and N. copelandii, both also from Mindanao. All three belong to the much larger "N. alata group", which also includes N. alata, N. extincta, N. graciliflora, N. hamiguitanensis, N. kitanglad, N. kurata, N. leyte, N. mindanaoensis, N. negros, N. ramos, N. saranganiensis, and N. ultra. These species are united by a number

Nepenthes talaandig is a tropical pitcher plant native to the Philippines. It is known only from the Pantaron Mountain Range of central Mindanao, where it grows terrestrially on ultramafic soils at around 1,000 m above sea level. The describing authors wrote that, based on its pitcher morphology, N. talaandig "is not directly related to any other Philippine species", though they suggested it might belong to the large "N. alata group". This complex includes N. alata, N. ceciliae, N. copelandii, N. cornuta, N. extincta, N. graciliflora, N. hamiguitanensis, N. kitanglad, N. kurata, N. leyte, N.

Nepenthes pantaronensis is a tropical pitcher plant native to the Philippines. It is known only from Mount Sumagaya and the Pantaron Mountain Range of central Mindanao, where it grows in lower and upper montane forest. On Mount Sumagaya it is sympatric with N. sumagaya and possible hybrids between these species have been recorded. Nepenthes pantaronensis is closely allied to N. petiolata and N. pulchra, both also from Mindanao.
