Heliamphora Heterodoxa

''Heliamphora heterodoxa'' ( = other, ''doxa'' = opinion, belief) is a species of marsh pitcher plant native to Venezuela and adjacent Guyana. It was first discovered in 1944 on the slopes interlinking Ptari-tepui and Sororopan-tepui and formally described in 1951.

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.

''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". 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.
