Tepui names shown in the tables are those used in Flora of the Venezuelan Guayana and Sarraceniaceae of South America, with alternate names and spellings given in brackets. Many additional orthographic variants are likely to exist and some localities remain the subject of considerable toponymic confusion; these cases are covered in the Notes section. Many of the tepui heights are approximate and likely to change as more accurate measurements become available. Only tepuis known to support Heliamphora are included in the tables (for example, not all parts of the Chimantá Massif or Eastern Tepuis chain are listed). Formally described species are listed first, followed by undescribed species, and finally 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 (?).
