Heliamphora Nutans

''Heliamphora nutans'' (Latin: ''nutans'' = nodding) is a species of marsh pitcher plant native to the border area between Venezuela, Brazil and Guyana, where it grows on several tepuis, including Roraima, Kukenán, Yuruaní, Maringma, and Wei Assipu. ''Heliamphora nutans'' was the first ''Heliamphora'' to be described and is the best known species.McPherson, S., A. Wistuba, A. Fleischmann & J. Nerz 2011. ''Sarraceniaceae of South America''. Redfern Natural History Productions, Poole.

''Heliamphora nutans'' was originally discovered in 1839 on Mount Roraima by the two brothers Robert and Richard Schomburgk, although they did not collect samples to return to Europe. The plant was formally described by George Bentham in 1840, becoming the type species of the genus. In 1881, David Burke was plant-hunting in the same area of British Guiana where he collected specimens of the plant and introduced it to England.

This species employs an 'aquaplaning' trapping mechanism similar to that of many tropical pitcher plants of the genus '' Nepenthes''.Ants aquaplaning on a pitcher plant
