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 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 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 attenboroughii, or Attenborough's pitcher plant, is a montane species of carnivorous pitcher plant of the genus Nepenthes. It is named after the celebrated broadcaster and naturalist Sir David Attenborough, who is a keen enthusiast of the genus. The species is characterised by its large and distinctive bell-shaped lower and upper pitchers and narrow, upright lid. The type specimen of N. attenboroughii was collected on the summit of Mount Victoria, an ultramafic mountain in central Palawan, the Philippines.

Nepenthes palawanensis is a tropical pitcher plant endemic to Sultan Peak on the island of Palawan in the Philippines, where it grows at elevations of 1100–1236 m above sea level. It was discovered in February 2010 by Jehson Cervancia and Stewart McPherson.
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 gantungensis is a tropical pitcher plant known from a single peak on the Philippine island of Palawan, where it grows at elevations of 1600–1784 m above sea level.
Nepenthes leonardoi is a tropical pitcher plant known from a single locality in central Palawan, the Philippines. It is closely allied to several other Palawan endemics, including N. deaniana, N. gantungensis, and N. mira. The traps of this species reach at least 24 cm in height. Some specimens are noted for producing very dark, almost black, upper pitchers.
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 pulchra is a tropical pitcher plant endemic to the Philippine island of Mindanao, where it grows at 1300–1800 m above sea level. Its discovery was announced online in August 2011.
Nepenthes epiphytica is a tropical pitcher plant known only from the Berau and East Kutai Regencies of East Kalimantan, Borneo, where it grows at an elevation of around 1000 m above sea level. Prior to its formal description as a species, N. epiphytica was considered to be a variant of the closely related N. fusca. Nepenthes epiphytica belongs to the loosely defined "N. maxima complex", which also includes, among other species, N. boschiana, N. chaniana, N. eymae, N. faizaliana, N. fusca, N. klossii, N. maxima, N. platychila, N. stenophylla, and N. vogelii.
Nepenthes monticola is a tropical pitcher plant known from a number of mountains in the west central highlands of western New Guinea, where it grows at elevations of 1400–2620 m above sea level. Prior to its description as a species in 2011, N. monticola was lumped with the closely related N. lamii.
Nepenthes sp. Anipahan is an undescribed tropical pitcher plant known only from Mount Anipahan in central Palawan, the Philippines, where it grows in upper montane forest at 1200–1400 m above sea level. It is very closely allied to N. leonardoi and may be conspecific with it.
Nepenthes aenigma is a tropical pitcher plant known from two mountains in Ilocos Norte province on the Philippine island of Luzon, where it grows at an elevation of around 1200 m above sea level. The species is notable for growing among dense vegetation in deep shade. It shows similarities to N. burkei and N. ventricosa.
