The natural range of the

table-top mountains of the region, known as tepuis

The genus has a highly disjunct distribution spread across two major groups of tepuis: the

Auyán Massif, Chimantá Massif, Eastern Tepuis chain, Los Testigos chain, and a number of outlying tepuis. Many of the summits of the eastern range are situated on a vast plateau known as the Gran Sabana. Only two species (H. ciliata and H. heterodoxa) are known with certainty from the Gran Sabana, and only H. ciliata is endemic to this habitat.^[2]

The altitudinal distribution of Heliamphora ranges from 860 m

above sea level for populations of H. neblinae on Cerro Avispa to as much as 2994 m for plants of H. hispida growing near the summit of Pico da Neblina in Cerro de la Neblina.^[2]

Key

Tepui names shown in the tables are those used in

natural hybrids

. Where published information is available, the altitudinal distribution of a taxon at a particular locality is given. In cases of unconfirmed locality records, the taxon name is preceded by a question mark (?).
Coordinates given correspond to the approximate centre points of tepui summit plateaus (though in the case of fragmented tepui complexes such as Cerro de la Neblina, the centre point itself may not lie on any plateau). Unless otherwise indicated, all other information presented in the tables is sourced from Sarraceniaceae of South America.

Western range

The western range of the genus is confined almost entirely to
Amazonas
state, Venezuela, but extends slightly into northernmost Brazil.

Neblina Massif

The
Cañón Grande, runs southwest to northeast through the middle of Cerro de la Neblina. The smaller outcrops of Cerro Aracamuni and Cerro Avispa, both reaching approximately 1600 m, lie to the north of this complex.^[3] The name Neblina Massif is sometimes applied specifically to Cerro de la Neblina, to the exclusion of Cerro Aracamuni and Cerro Avispa.^[2]

Four species are native to this area, all local endemics: H. ceracea, H. hispida, H. neblinae, and H. parva, though only the range of H. neblinae extends to the two northern cerro-plateaus. No Heliamphora are found on the small granitic outcrop of Cerro Aratitiyope (1700 m) to the north of the Neblina Massif.^[2]

If not, it would be the only known species not found in Venezuela.

H. hispida 1800–2994 m Found in southern portion of Cerro de la Neblina, on and around Pico da Neblina and Pico 31 de Março (including area around the Titirico River). Additional populations may grow in the largely unexplored Cañón Grande. Plants near the summit of Pico da Neblina (2994 m) represent the upper altitudinal limit for the genus.

H. neblinae 2000–2200 m Known with certainty from southern portion of Cerro de la Neblina, where it grows on and around Pico da Neblina. Herbarium material suggests it is also present in the northern parts, though it has not been observed in the extreme north.

H. parva 1750–2200 m Recorded from southern part of Cerro de la Neblina around Pico da Neblina at 2000–2200 m, though the largest known stands grow in the northwestern part of the massif, at lower elevations of 1750–1850 m. It is unknown whether the range of this species extends into the central valleys of Cerro de la Neblina.

Bolívar
state, Venezuela, but also extends into portions of western Guyana and northern Brazil.

Angasima and Upuigma

The imposing peaks of
Upuigma Tepui (2100 m) lie south of the much larger Chimantá Massif, from which they are separated by the Río Aparurén valley.^[3] Three Heliamphora species are native to Angasima Tepui: the undescribed endemic H. sp. 'Angasima Tepui' and two species shared with the nearby Chimantá Massif (H. huberi and H. pulchella). Only the range of H. pulchella extends to the isolated peak of Upuigma Tepui.^[2]

5°46′01″N 61°48′40″W / 5.766986°N 61.810999°W / 5.766986; -61.810999 (Ptari Tepui) ?H. collina Reportedly observed on mountain, but this requires confirmation.

?H. heterodoxa 2000–2200 m Collected from "southwest-facing shoulder" of Ptari Tepui in 1944; this population has not been relocated since its discovery.

H. purpurascens 2400–2500 m Restricted to flat summit.

H. sarracenioides 2400–2450 m Restricted to flat summit.

H. purpurascens × H. sarracenioides Restricted to flat summit. Complex backcrosses are common and may outnumber the parent species in some areas.

Uplands

The uplands of the Venezuelan Guayana are regarded as those areas with an elevation of approximately 500–1500 m, with higher elevations being highland and lower ones lowland.^[3]
The
Guayana Highlands, the name Cerro Venamo has been inconsistently applied to a number of adjacent areas.^{[nb f]}

Heliamphora ciliata is endemic to these upland areas and H. heterodoxa may also be (though see Ptari Tepui).^[2]^{[nb g]}

Notes

a.^{^} The altitudinal distribution of H. ceracea is not specified in Sarraceniaceae of South America, either in the species profile or the formal description, but the holotype was collected at an elevation of 1900 m.^[2]

b.
GPS equipment by cartographer Marco Aurélio de Almeida Lima, a member of a Brazilian army expedition, puts it at 2,994 m (9,823 ft). This is now recognised by the Brazilian Institute of Geography and Statistics (IBGE), the federal government's official geographic survey and census agency, which jointly organised the expedition. The height of Pico 31 de Março / Pico Phelps was similarly reduced from 2,992 m (9,816 ft) to 2,973 m (9,754 ft).^[8]

c.
Auyán Tepui,^[5] while in Sarraceniaceae of South America (co-authored by Fleischmann) its range is said to encompass both Auyán Tepui and Cerro La Luna, with photographs from both localities included.^[2]

d.^{^} The maps provided in Sarraceniaceae of South America place Maringma Tepui on the Brazil–Venezuela border some distance southeast of Mount Roraima,^[2] but other published sources place it just inside Guyana near the border with Brazil, around 17 km east of Mount Roraima (5°12′59″N 60°35′07″W / 5.216434°N 60.585165°W / 5.216434; -60.585165 (Maringma Tepui)).^[9]^[10]^[11] In Sarraceniaceae of South America it is stated that Maringma Tepui was previously incorrectly called "Mount Yakontipu" by Fleischmann et al. (2007)^[12] in their description of Drosera solaris.^[2]

e.^{^} Otto Huber summarised this muddled toponymy as follows: "There is, however, confusion concerning the precise names of the two central mountains; according to Brewer-Carías (1978), Murochiopán-tepui is the name of a smaller lateral mountain of Aparamán [5°52′32″N 62°06′48″W / 5.875429°N 62.113452°W / 5.875429; -62.113452], followed to the east by the high Tereke Yurén-tepui and the lower Tucuy-wo-cuyén-tepui, whereas members of the Terramar Foundation expeditions (Steyermark 1986a; Holst 1987; George 1988) apply the name Murisipán-tepui to Brewer's Tereke Yurén-tepui, and the name Tereke-yurén-tepui to Brewer's Tucuy-wo-cuyén-tepui, omitting the name of the smaller lateral mountain of Aparamán-tepui."^[3] A yet different sequence (and spelling) of names can be found in, for example, the formal description of H. folliculata, namely: Murosipan, Aparaman, Tereke-Yuren, and Kamarkaiwaran.^[13]

f.
Cerro Venamo (5°58′N 61°25′W / 5.97°N 61.41°W / 5.97; -61.41 (Cerro Venamo)), which forms part of the international boundary between Guyana and Venezuela, does not correspond to the mountain originally given this name by Julian Alfred Steyermark. The latter is known to host Heliamphora while the former is not.^[14]

g.^{^} This assumes that the high slope- and summit-growing H. sp. 'Akopán Tepui' and H. sp. 'Angasima Tepui' are not conspecific with H. heterodoxa.
