Heliamphora heterodoxa (Greek: heteros = other, doxa = opinion, belief) is a species of marsh pitcher plant native to Venezuela[2] and adjacent Guyana.[3] It was first discovered in 1944 on the slopes interlinking Ptari-tepui and Sororopan-tepui and formally described in 1951.[2]
This Heliamphora is closely related to H. glabra and the latter was for a long time considered a form of H. heterodoxa. It is one of four Heliamphora taxa formally described by Julian A. Steyermark.[4]
Heliamphora heterodoxa is known to tolerate slightly higher temperatures compared to other Heliamphora species, due to its habitats being located in upland wetlands and lower elevation Pantepui habitats (approx. 1200m - 1500m a.s.l.). The plant grows vigorously and exhibits a large, overhanging nectar spoon.

Etymology
The name "heterodoxa", meaning "variable", was given to the species by J.A. Steyermark who had observed that "considerable variation occurs within this species".[2] An expedition to the locus classicus of H. heterodoxa on the southwestern slopes of Ptari-tepui undertaken in May 2018 confirmed occurrences of one other species of Heliamphora, H. collina, as well as a H. collina x purpurascens hybrid swarm being present at the very same location.[5]
