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 lamii is a tropical pitcher plant endemic to New Guinea, where it grows at an altitude of up to 3520 m above sea level, higher than any other Nepenthes species. Although once confused with N. vieillardii and previously regarded as conspecific with the closely related N. monticola, it is now recognised as a distinct species.
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 philippinensis is a tropical pitcher plant endemic to the Philippines. It is known from Palawan and the neighbouring Calamian Islands and Linapacan, where it grows at 0–600 metres (2,000 ft) above sea level.
Nepenthes danseri is a species of tropical pitcher plant. It is known only from the northern coast of Waigeo Island; plants from Halmahera, the largest of the Maluku Islands, are now recognised as belonging to a separate species, N. halmahera.
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 of Sumatra and Peninsular Malaysia is a monograph by Charles Clarke on the tropical pitcher plants of Sumatra, Peninsular Malaysia, and their minor surrounding islands. It was published in 2001 by Natural History Publications (Borneo). Clarke described it as "intermediate between an ecological monograph and a taxonomic one".
"A skeletal revision of Nepenthes (Nepenthaceae)" is a monograph by Matthew Jebb and Martin Cheek on the tropical pitcher plants of the genus Nepenthes. It was published in the May 1997 issue of the botanical journal Blumea. The work represented the first revision of the entire genus since John Muirhead Macfarlane's 1908 monograph. Jebb and Cheek's revision was based on "collaborative work by both authors since 1984, largely on herbarium specimens, but including fieldwork in New Guinea, Indonesia, Malaysia, Singapore and Madagascar". It was a precursor to their more exhaustive 2001 monograph, "Nepenthaceae".
Nepenthes of Borneo is a monograph by Charles Clarke on the tropical pitcher plants of Borneo. It was first published in 1997 by Natural History Publications (Borneo), and reprinted in 2006. Clarke describes it as "primarily an ecological monograph".
"Nepenthaceae" is a monograph by Martin Cheek and Matthew Jebb on the tropical pitcher plants of Malesia, which encompasses Brunei, Indonesia, Malaysia, Papua New Guinea, the Philippines, and Singapore. It was published in 2001 by the National Herbarium of the Netherlands as the fifteenth volume of the Flora Malesiana series. The species descriptions presented in the monograph are based on the authors' field observations in Borneo, New Guinea, and Peninsular Malaysia, as well as the examination of plant material deposited at 20 herbaria.
Pitcher-Plants of Borneo is a monograph by Anthea Phillipps and Anthony Lamb on the tropical pitcher plants of Borneo. It was first published in 1996 by Natural History Publications (Borneo), in association with the Royal Botanic Gardens, Kew and the Malaysian Nature Society. An updated and much expanded second edition was published in 2008 as Pitcher Plants of Borneo, with Ch'ien Lee as co-author.
"An account of Nepenthes in New Guinea" is a monograph by Matthew Jebb on the tropical pitcher plants of New Guinea. It was published in the March 1991 issue of Science in New Guinea, a journal of the University of Papua New Guinea. It remains the only major monograph devoted to the tropical pitcher plants of the island.
The Carnivorous Plants is a major work on carnivorous plants by American botanist Francis Ernest Lloyd. It was first published in 1942 by the Chronica Botanica Company as the ninth volume of A New Series of Plant Science Books. It was reprinted in 1976 by Dover Publications of New York and Constable of London. Although primarily dealing with plants, the book also briefly covers carnivorous fungi. The chapter describing the structure and functioning of Utricularia traps is particularly detailed. Lloyd's book was the most important scientific work on carnivorous plants since Charles Darwin's Insectivorous Plants of 1875.
Nepenthes abalata is a tropical pitcher plant known from three western islands of the Philippines: Culion, Cuyo, and Malalison. It has been recorded from coastal grassland and scrub at elevations of 0–20 m above sea level.
Nepenthes negros is a tropical pitcher plant native to the Philippines, specifically the islands of Biliran and Negros.
