Nepenthes sibuyanensis is a tropical pitcher plant endemic to Sibuyan Island in the Philippines, after which it is named.
Nepenthes veitchii, or Veitch's pitcher-plant, is a Nepenthes species from the island of Borneo. The plant is widespread in north-western Borneo and can also be found in parts of Kalimantan. It grows in lowland Dipterocarp forest, typically near rivers, and on ridgetops in mossy forests, from 0 to 1,600 meters elevation. Nepenthes veitchii usually grows as an epiphyte, though the form from Bario seems to be strictly terrestrial and has not been observed to climb trees.
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 pervillei is the only pitcher plant found in the Seychelles, where it is endemic to the islands of Mahé and Silhouette. It grows in rocky areas near granitic mountain summits, its roots reaching deep into rock fissures. The species has an altitudinal range of 350–750 m above sea level. Like all members of the genus, N. pervillei is dioecious, having separate male and female plants.
Nepenthes ephippiata, or the saddle-leaved pitcher-plant, is a tropical pitcher plant endemic to Borneo. It occurs in the Hose Mountains of central Sarawak, as well as Mount Raya and Bukit Lesung in Kalimantan. It grows in montane forest from 1,000 to 1,900 meters elevation.
Nepenthes boschiana, or Bosch's pitcher-plant, is a tropical pitcher plant endemic to Borneo. It is most closely allied to N. faizaliana. Nepenthes borneensis is considered a synonym of this species. Nepenthes boschiana has no known natural hybrids. No valid forms or varieties have been described. Nepenthes boschiana belongs to the loosely defined "N. maxima complex", which also includes, among other species, N. chaniana, N. epiphytica, N. eymae, N. faizaliana, N. fusca, N. klossii, N. maxima, N. platychila, N. stenophylla, and N. vogelii.
Nepenthes mapuluensis, the Mapulu pitcher-plant, is a species of tropical pitcher plant native to East Kalimantan, Borneo. It is known only from a restricted geographical range and is listed as Endangered on the IUCN Red List.
Nepenthes burkei, named after British plant collector David Burke, is a tropical pitcher plant native to the island of Mindoro in the Philippines, where it grows at an elevation of 1100–2000 m. It is very closely related to N. sibuyanensis and N. ventricosa. It has only recently entered wider cultivation.
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 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 argentii is a highland Nepenthes pitcher plant native to Mount Guiting-Guiting on Sibuyan Island in the Philippines. It is possibly the smallest species in the genus and does not appear to have a climbing stage.
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 tobaica is a tropical pitcher plant endemic to Sumatra. It is particularly abundant around Lake Toba, after which it is named.
Nepenthes singalana is a tropical pitcher plant endemic to the island of Sumatra, where it grows at 2000–2900 m above sea level. It is most closely allied to N. diatas and N. spathulata.
Nepenthes densiflora is a tropical pitcher plant endemic to Sumatra, where it grows at an altitude of between 1700 and 3200 m above sea level.
Nepenthes thorelii is a tropical pitcher plant endemic to Indochina. Very little is known about N. thorelii and it is unlikely to have entered cultivation, although various other taxa are often mislabelled as this species in the plant trade. Prior to its rediscovery in 2011, N. thorelii was considered possibly extinct, both in the wild and in cultivation.
Nepenthes tomoriana is a species of pitcher plant endemic to Sulawesi, where it grows at an elevation of 0–500 m above sea level.
Nepenthes masoalensis is one of two tropical pitcher plant species from Madagascar, the other being N. madagascariensis.
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 alba is a tropical pitcher plant endemic to Peninsular Malaysia. The specific epithet alba is derived from the Latin word albus, meaning "white", and refers to the colour of the upper pitchers.
