Distribution of N. aristolochioides.

Nepenthes aristolochioides (Latin: Aristolochia = a genus of shrubs and vines, oides = resembling) is a highland Nepenthes pitcher plant species, native to Sumatra, where it grows at an altitude of 2000-2500 m. It has an extremely unusual pitcher morphology, having an almost vertical opening to its traps (similar to N. klossii).

Status: N. aristolochioides is considered Critically Endangered as its distribution is restricted to a single mountain. This species is presently known only from Gunung Tujuh, but it is possible that plants are also present on neighbouring Gunung Kerinci, which is Sumatra's highest peak. N. aristolochioides is severely threatened in the wild by over-collection, despite the fact that all known populations lie within Kerinci Seblat National Park.

No infaunal organisms have been recorded from the pitchers of N. aristolochioides. It is thought that the structure of the traps may serve to disorient emerging adults and so infaunal species may avoid colonising them.
