Nepenthes pulchra is a tropical pitcher plant endemic to the Philippine island of Mindanao, where it grows at 1,300–1,800 m above sea level. Its discovery was announced online in August 2011.

Nepenthes micramphora is a tropical pitcher plant known only from Mount Hamiguitan on the island of Mindanao in the Philippines. It is a highland plant growing at elevations of 1,100–1,635 m. Nepenthes micramphora is closely allied to N. abgracilis and N. cid, both also from Mindanao, and together these species comprise the informal "N. micramphora group". The specific epithet micramphora is derived from the Greek mikros (small) and Latin amphora (amphora, urn), and references the tiny pitchers of this species.

Nepenthes hamiguitanensis is a tropical pitcher plant endemic to a single peak on the Philippine island of Mindanao, where it grows at elevations of 1,200–1,600 m above sea level. Once thought to be a natural hybrid between N. micramphora and N. peltata, this plant is now considered a species of possible hybridogenic origin. It produces squat upper pitchers that vary greatly in pigmentation, from red speckled to yellow throughout. The specific epithet hamiguitanensis is derived from the name of Mount Hamiguitan, to which it is endemic, and the Latin ending -ensis, meaning "from".

Nepenthes ceciliae is a tropical pitcher plant endemic to the Philippine island of Mindanao, where it grows at 1500–1880 m above sea level. Its discovery was announced online in August 2011. Nepenthes ceciliae belongs to the informal "N. alata group", which also includes N. alata, N. copelandii, 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 of morphological characters, including winged petioles, lids with basal ridges on the lower surface (often

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 justinae is a tropical pitcher plant known only from Mount Hamiguitan on the Philippine island of Mindanao, where it grows at elevations of 1,000–1,620 m above sea level. The specific epithet justinae honours Justina Yu, the mayor of San Isidro, Davao Oriental, Mindanao, whose efforts helped get the Mount Hamiguitan Range Wildlife Sanctuary inscribed as a UNESCO World Heritage Site in 2014. Nepenthes justinae has no confirmed natural hybrids, although certain plants from Mount Hamiguitan may represent crosses involving it and N. hamiguitanensis, N. micramphora, and N. peltata, the

Nepenthes viridis is a tropical pitcher plant endemic to the Philippines. It is known only from coastal areas at low altitude and has been recorded from Dinagat, Samar, and a number of surrounding islets. It is closely allied to the N. alata group of species. The specific epithet viridis is Latin for "green" and refers to the plant's typical yellowish-green pitcher colouration, which is maintained irrespective of sun exposure.

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.
