Heliamphora chimantensis is a species of marsh pitcher plant endemic to the Chimantá Massif in Venezuela. It has been recorded from Apacará Tepui and Chimantá Tepui. The species is thought to be more closely related to Heliamphora tatei and Heliamphora neblinae than to other species found in the Gran Sabana region. Like other members of the genus Heliamphora, it survives in nutrient-poor environments by capturing and digesting insects using specialized pitcher-shaped leaves.

Nepenthes ovata is a tropical pitcher plant endemic to Sumatra. The specific epithet ovata is Latin for "ovate" and refers to the shape of the lower pitchers.

Nepenthes mantalingajanensis is a tropical pitcher plant known only from the summit region of Mount Mantalingajan, the highest point on the Philippine island of Palawan, after which it is named.

Heliamphora pulchella (Latin: pulchellus = pretty) is a species of marsh pitcher plant endemic to the Chimanta Massif and surrounding tepuis in Venezuela. It is one of the smallest species and closely related to H. minor.

Nepenthes talangensis is a tropical pitcher plant endemic to Sumatra, where it grows in upper montane forest at elevations of 1,800–2,500 m above sea level. The specific epithet talangensis is derived from the name of Mount Talang, to which it is endemic, and the Latin ending -ensis, meaning "from".

Nepenthes tenuis (; from Latin tenuis 'thin, fine, slender') is a tropical pitcher plant endemic to the Indonesian island of Sumatra. The species was first collected in 1957, from a remote mountain in the western part of the island. It remained undescribed until 1994, and was only rediscovered in the wild in 2002. Prior to this, N. tenuis was known solely from a single photograph and dried herbarium specimen.

Nepenthes longifolia is a tropical pitcher plant endemic to Sumatra, where it grows at elevations of between 300 and 1,100 m above sea level. The specific epithet longifolia, formed from the Latin words longus (long) and folius (leaf), refers to the exceptionally large leaves of this species.

Nepenthes flava is a tropical pitcher plant endemic to northern Sumatra, where it grows in montane forest at 1,800–2,200 m above sea level. The specific epithet flava is derived from the Latin word for "yellow" and refers to the typical colouration of the plant's upper pitchers and other vegetative parts.

Heliamphora folliculata (Latin: folliculatus = having follicles) is a species of Marsh Pitcher Plant endemic to the Aparaman group of tepuis in Venezuela. It grows on all four mountains: Aparaman Tepui, Murosipan Tepui, Tereke Tepui and Kamakeiwaran Tepui. The nectar spoon of this species, which bears giant extrafloral nectaries within its internal chamber, may have evolved to prevent rain from washing away the energetically costly nectar produced by the plant.

Nepenthes nigra is a tropical pitcher plant known from a number of mountains across Central Sulawesi, where it grows at elevations of 1,500–2,700 m (4,900–8,900 ft) above sea level. The specific epithet nigra refers to the dark colouration of the pitchers and stem. The species is closely related to N. hamata and N. tentaculata.

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 1,400–2,620 m above sea level. Prior to its description as a species in 2011, N. monticola was lumped with the closely related N. lamii.

Nepenthes hamiguitanensis is a tropical pitcher plant endemic to a single peak on the Philippine island of Mindanao, where it grows at elevations of 1,200–1,600 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. The specific epithet hamiguitanensis is derived from the name of Mount Hamiguitan, to which it is endemic, and the Latin ending -ensis, meaning "from".

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 1,000 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. The specific epithet epiphytica

Heliamphora glabra (Latin: glaber = bald) is a species of marsh pitcher plant native to Serra do Sol in Venezuela. It was for a long time considered a form of H. heterodoxa, but has recently been raised to species rank.

Heliamphora exappendiculata (Latin: ex = without, appendicula = small appendage) is a species of marsh pitcher plant native to the Chimantá and Aprada Massifs of Bolívar state, Venezuela. It was for a long time considered a variety of H. heterodoxa, but has recently been raised to species rank. Pitchers collect insects on flattened pitcher mouths which function as 'landing platforms' upon which prey falls from surrounding vegetation. Also, the pitcher shape effectively collects leaf litter and organic debris which may serve as additional source of nutrition for plants, similarly to H. ionasi.

Drosera solaris is a species of sundew native to the highlands of Guyana. It is thought to be most closely related to Drosera felix and Drosera kaieteurensis.

Nepenthes lavicola (; from Latin: lavicola growing upon lava) is a tropical pitcher plant species endemic to the Geureudong Massif of Aceh, northern Sumatra, where it grows at 2,000–2,600 m above sea level. It is thought to be most closely related to N. singalana and N. spectabilis. Nepenthes lavicola is notable for its very prominent bracts, which often overarch the flowers and may be up to 7 cm long at the base of female inflorescences. This species is also unusual in that it bears up to two bracts per pedicel or partial peduncle. Swiss botanist Albert Friedrich Frey-Wyssling mentioned N.

Nepenthes undulatifolia is a tropical pitcher plant known only from South East Sulawesi, where it grows at an elevation of around 1,800 m above sea level. The specific epithet undulatifolia refers to the wavy laminar margins of this species.

Heliamphora sarracenioides (Latin: Sarracenia = genus of North American pitcher plants, -oides = resembling) is a species of marsh pitcher plant endemic to Ptari Tepui in Bolívar state, Venezuela. Approximately 200 mature plants were observed in the type locality, however this site's true location and information regarding sympatric species has not been disclosed for conservation reasons. The species differentiates itself from others by the extremely wide pitcher lid, which resembles Sarracenia species. It is closest to H. heterodoxa and H. folliculata, from which it can be distinguished by

Heliamphora purpurascens is a species of marsh pitcher plant known only from the summit area of Ptari Tepui in Venezuela, where it grows at elevations of 2,400–2,500 m.

Heliamphora hispida (Latin: hispidus = covered with stiff or rough hairs, bristly) is a species of Marsh Pitcher Plant endemic to Cerro Neblina, the southernmost tepui of the Guiana Highlands at the Brazil-Venezuela border.

Heliamphora ciliata is a species of Marsh Pitcher Plant endemic to Venezuela. It is restricted to a small number of swampy meadows in the uplands of Gran Sabana. In this habitat it is sympatric with a species of Stegolepis (Rapateaceae). Unusually for the genus, H. ciliata is a submontane plant, growing at an elevation of only 900 m.

Heliamphora parva is a species of marsh pitcher plant known only from the Neblina Massif in Venezuela, where it grows at elevations of 1750–2200 m.

Heliamphora collina is a species of marsh pitcher plant known from the Los Testigos and Ptari-tepui massifs in Venezuela It grows at elevations of 1700–1825 m. The first specimens of the species were first collected by Otto Huber, Julian Steyermark and others in 1986 and originally classified as Heliamphora heterodoxa. After additional in-situ studies it was described as a new species in 2011 by Andreas Wistuba, Joachim Nerz, Stewart McPherson and Andreas Fleischmann. First believed to be endemic to the common foothills of the four tepuis of the Los Testigos chain, observations of plants

Heliamphora arenicola is a species of marsh pitcher plant known only from the western side of the Ilu–Tramen Massif in Venezuela's Gran Sabana, where it grows at elevations of less than 2000 m. It may also occur on Karaurin Tepui.

Nepenthes cornuta is a tropical pitcher plant native to the Philippines. It is known only from the Pantaron Mountain Range of central Mindanao, where it grows terrestrially on ultramafic soils at around 1000 m above sea level. This species is most closely allied to N. ceciliae and N. copelandii, both also from Mindanao. All three belong to the much larger "N. alata group", which also includes N. alata, N. extincta, N. graciliflora, N. hamiguitanensis, N. kitanglad, N. kurata, N. leyte, N. mindanaoensis, N. negros, N. ramos, N. saranganiensis, and N. ultra. These species are united by a number

Heliamphora uncinata is a species of Marsh Pitcher Plant endemic to Venezuela. This species of carnivorous plant is known as a pitcher plant. Individuals use tube like leaves to trap insects that slip into the bottom. At the bottom of the "pitcher" there are digestive juices which slowly digest the prey item to give the plant additional nutrients. The pitchers of this species are around 25–35 cm long, and are 8–10 cm wide at the opening. The pitcher mouth is circular in shape and the back is raised to form the lid. It is known only from the type collection, which was made in a narrow canyon

Heliamphora huberi is a species of Marsh Pitcher Plant endemic to the Chimantá Massif in Venezuela, where it grows at elevations of 1850–2200 m in a variety of habitats. It has thus far been recorded from Angasima-tepui, Apacará-tepui, Amurí-tepui, Acopán-tepui, and the border of Torono- and Chimantá-tepui. Due to its intermediate appearance between species related to H. minor and H. heterodoxa, it is suspected to be of hybridogenic origin.

Heliamphora ceracea is a species of marsh pitcher plant known only from the Brazilian side of Pico da Neblina in the Neblina Massif. It has been collected from an elevation of 1900 m.

Nepenthes justinae is a tropical pitcher plant known only from Mount Hamiguitan on the Philippine island of Mindanao, where it grows at elevations of 1,000–1,620 m above sea level. The specific epithet justinae honours Justina Yu, the mayor of San Isidro, Davao Oriental, Mindanao, whose efforts helped get the Mount Hamiguitan Range Wildlife Sanctuary inscribed as a UNESCO World Heritage Site in 2014. Nepenthes justinae has no confirmed natural hybrids, although certain plants from Mount Hamiguitan may represent crosses involving it and N. hamiguitanensis, N. micramphora, and N. peltata, the
