A cladistic approach to the Neotropical Aristolochiaceae, based on 41 morphological characters, was conducted to evaluate the phylogeny of Aristolochia sect. Gymnolobus Duchartre along with the other two genera of the subfamily Aristolochiodeae sensu Schmidt (1935), Euglypha Chodat & Hassler, and Holostylis Duchartre. A single cladogram was obtained, in which the genus Aristolochia is shown to be paraphyletic; the basal branch within the ingroup is Aristolochia ser. Thyrsicae F. Gonzalez, followed by A. subsect. Pentandrae Duchartre. The two monospecific South American genera Euglypha and Holostylis resulted to be placed in crown clades, as the sister groups of Aristolochia subser. Hexandrae, and Aristolochia subser. Anthocaulicae F. Gonzalez, respectively. Therefore, the inclusion of these two genera within Aristolochia is required if monophyly is to be maintained at a generic level. Finally, the required nomenclatural combinations are proposed.
