Nepenthes truncata is a tropical pitcher plant endemic to the Philippines. It is known from the islands of Dinagat, Leyte, and Mindanao. The species grows at an elevation of 0–1500 m above sea level. Nepenthes truncata is characterised by its heart-shaped (truncate) leaves and very large pitchers, which can reach up to 40 cm in height.
Nepenthes alata is a tropical pitcher plant endemic to the Philippines. Like all pitcher plants, it is carnivorous and uses its nectar to attract insects that drown in the pitcher and are digested by the plant. It is highly polymorphic, and its taxonomy continues to be subject to revisions.
Nepenthes copelandii is a species of pitcher plant native to the island of Mindanao in the Philippines. Originally known from Mount Apo near Davao City and Mount Pasian near Bislig, it has since been discovered on a number of peaks throughout Mindanao. It may also be present on the nearby island of Camiguin. The species has a wide altitudinal distribution of 1100–2400 m above sea level. Nepenthes copelandii has no known natural hybrids. No forms or varieties have been described.
Nepenthes mindanaoensis is a tropical pitcher plant native to the Philippine islands of Mindanao and Dinagat.
Nepenthes merrilliana is a tropical pitcher plant endemic to the Philippines. It produces some of the largest pitchers in the genus, rivalling those of N. rajah.
Nepenthes bellii is a tropical pitcher plant endemic to the Philippine islands of Mindanao and Dinagat, where it grows at elevations of 0–800 m above sea level.
Nepenthes mira is a highland pitcher plant endemic to Palawan in the Philippines. It grows at elevations of 1550–1605 m above sea level.
Nepenthes petiolata is a highland Nepenthes pitcher plant species endemic to Mindanao island in the Philippines, where it grows at an elevation of 1,450–1,900 metres (4,800–6,200 ft) above sea level.
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 1100–1635 m.

He is currently Manager Biodiversity Services at the National Herbarium of Victoria, Royal Botanic Gardens Melbourne, where he oversees identification botany services, the Library and Artwork components of the State Botanical Collection, and the botanical journal Muelleria, a peer-reviewed scientific journal on botany published by the Royal Botanic Gardens Victoria, for which he is Editor in Chief.
Pitcher Plants of the Old World is a two-volume monograph by Stewart McPherson on the pitcher plants of the genera Nepenthes and Cephalotus. It was published in May 2009 by Redfern Natural History Productions and covers all species known at the time. The work was edited by Alastair Robinson and Andreas Fleischmann.
Nepenthes hamiguitanensis is a tropical pitcher plant endemic to a single peak on the Philippine island of Mindanao, where it grows at elevations of 1200–1600 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.
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 ramos is a tropical pitcher plant native to the northeastern Mindanao, Philippines. It is known from only a handful of herbarium specimens collected in 1919 at an elevation of 670 m above sea level. It likely grows in the forest on ultramafic soils.
Nepenthes negros is a tropical pitcher plant native to the Philippines, specifically the islands of Biliran and Negros.
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.
Nepenthes extincta is a tropical pitcher plant native to the Philippines. It is known only from Surigao del Sur, Mindanao, where it has been recorded at c. 400 metres (1,300 ft) altitude.
Nepenthes leyte is a tropical pitcher plant native to the Philippines. It appears to be endemic to the island of Leyte, after which it is named. It has been recorded from submontane mossy forest at 900 m altitude.
