Another spontaneous hybrid of the labiata-complex apparently, I grew this specimen from seed obtained as Aristolochia galeata. The coloration and prolonged limb make me suppose A. pohliana might be the other part but as hybridization happened uncontrolled, this is just a guess and not verifiable any more.
Aristolochia pohliana is quite well-known to be the most potent hybridizing species of the labiata group - that would make sense as well if motherplants stood not far away from each other.
