Aristolochia pohliana undoubtedly belongs to the labiata complex characterized by the well-known Pelican-like flower type.
It's made itself a name as the most feral hybridizer in the affinity of this complex and is responsible for a huge "mess" of spontaneous hybrids (e.g. Aristolochia [galeata x cf. pohliana] and many, many more ) especially abundant in cultivation when uncontrolled, open pollination occurs.
The "true", wild-type morph is quite a stunner nevertheless. When in female stage (1st day of flowering) it emits a very unpleasant odor.
