The Eastern Tepuis chain, or Roraima-Ilú range, stretches in a northwesterly direction from the tripoint of Brazil, Guyana, and Venezuela, closely following the Guyana-Venezuela border, with an isolated double-peaked plateau (Serra do Sol or Uei Tepui) to the south. Moving in a northwesterly direction from Serra do Sol (2150 m), the major summits of this chain are Mount Roraima (2810 m), Kukenán Tepui (2650 m), Yuruaní Tepui (2400 m), Wadakapiapué Tepui (2000 m), Karaurín Tepui (2500 m), Ilú Tepui (2700 m), and Tramen Tepui. With the exception of the tiny Wadakapiapué Tepui (), all of these peaks are known to support Heliamphora. The Eastern Tepuis chain includes some of the most widely visited tepuis, particularly Roraima and nearby Kukenán. The Ilú (Uru) and Tramen Tepuis are treated here as a single locality since they are joined by a common base and share the same assemblage of Heliamphora taxa.
