Interestingly, flowers with more than six stamens are found only in some African and Malesian species of subgenus Pararistolochia, and can occur without affecting the 6-merous gynoecium, whereas the pentandrous condition is always associated to the presence offive carpels (Gonzalez & Stevenson, 2000, 2002) and is characteristic of a group of species, most of which are found in S United States and N Mexico.

Alternatively, the pentandrous species of Aristolochia have been segregated into a separate genus, Einomeia, by Rafinesque (1828), which was later emmended by Klotzsch (1859), and later accepted asa distinct genus by Huber (1985, 1993), and Mabberley (2008).

The pentandrous species have in common with the first potential sister group the presence of a single, bracteate flower per node (character 14) and the complete syrinx (29).
