Revalidación de Aristolochia pearcei Phil. y notas acerca de la identidad de A. bridgesii (Klotzsch) Duch. (Aristolochiaceae)

Abstract

Mediante un estudio detallado de las descripciones originales y de los ejemplares tipo, además del análisis de nuevos materiales recolectados, se establece que Aristolochia bridgesii y A. pearcei, entidades hasta ahora consideradas sinónimos, corresponden a especies distintas, con una morfología floral notoriamente diferente y con áreas de distribución alopátricas separadas por más de 300 km en sentido latitudinal. De este modo, para Chile se reconocen, a la fecha, tres especies, A. bridgesii, A. pearcei y A. chilensis. Se entrega una completa ilustración de A. bridgesii y una clave para el género en Chile. Adicionalmente A. bridgesii y A. pearcei son lectotipificadas. Resumen: 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.
