Revalidación de Aristolochia pearcei Phil. y notas acerca de la identidad de A. bridgesii (Klotzsch) Duch. (Aristolochiaceae) Revalidation of Aristolochia pearcei Phil. and notes on the identity of A. bridgesii (Klotzsch) Duch. (Aristolochiaceae)

Through a detailed study of the original descriptions and type materials, in addition to analyses of the new collected material, we have established that Aristolochia bridgesii and A. pearcei, entities that have been considered synonyms until now, correspond to different species, with notoriously different floral morphology and allopatric geographic distributions, separated in latitude by more than 300 km. Thus, three species are recognized for Chile: A. bridgesii, A. pearcei and A. chilensis. A complete illustration of A. bridgesii and key for the genus in Chile are provided. In addition, A. bridgesii and A. pearcei are lectotypified.
