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 sanguinea is a large and vigorous Nepenthes pitcher plant species, native to Peninsular Malaysia and southernmost Thailand, where it grows at 300–1800 metres altitude. The pitchers are variable in size, from 10–30 cm tall, and range from green and yellow to orange and red. The insides of the pitchers are usually speckled with its two main colors. It was introduced to Victorian Britain around 1847 by Cornish plant hunter and botanist Thomas Lobb via the Veitch Nurseries.
Nepenthes macfarlanei is a carnivorous pitcher plant species endemic to Peninsular Malaysia. It produces attractive red-speckled pitchers. Lower pitchers are ovoid or infundibular in the lower half and globose or cylindrical above and up to 25 cm high. Upper (aerial) pitchers are of a lighter colour with wings reduced to rubs. The lower surface of the lid is densely covered with short, white hairs. This is a characteristic morphological feature of this species, but at present its function is unknown.
Nepenthes faizaliana is a tropical pitcher plant endemic to the limestone cliffs of Gunung Mulu National Park in Sarawak, Borneo. It is thought to be most closely related to N. boschiana.
Nepenthes benstonei is a tropical pitcher plant endemic to Peninsular Malaysia, where it grows at elevations of 150–1350 m above sea level. The specific epithet benstonei honours botanist Benjamin Clemens Stone, who was one of the first to collect the species.
Nepenthes bongso is a tropical pitcher plant endemic to Sumatra, where it has an altitudinal distribution of 1000–2700 m above sea level. The specific epithet bongso refers to the Indonesian legend of Putri Bungsu, the spirit guardian of Mount Marapi.
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 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 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 eustachya is a tropical pitcher plant endemic to Sumatra, where it grows from sea level to an elevation of 1600 m. The specific epithet eustachya, formed from the Greek words eu (true) and stachys (spike), refers to the racemose structure of the inflorescence.
Nepenthes gracillima is a highland Nepenthes pitcher plant species, native to Peninsular Malaysia.
Nepenthes ramispina is a highland Nepenthes pitcher plant species, native to Peninsular Malaysia. It was once regarded as being similar to N. gracillima, but studies of the two species in nature have shown that they are readily distinguishable in isolation, N. gracillima being far more readily confused with N. macfarlanei in its rosette 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 diatas is a tropical pitcher plant endemic to Sumatra, where it grows at an altitude of 2,000–2,900 metres (6,600–9,500 ft) above sea level.
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 lavicola is a tropical pitcher plant species endemic to the Geureudong Massif of Aceh, northern Sumatra, where it grows at 2000–2600 m above sea level. It is thought to be most closely related to N. singalana and N. spectabilis.
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.
