摘要

The taxonomy of the Chilean species of Aristolochia has long been a subject of debate, complicated by the broad distribution of the genus, morphological plasticity within species, and a paucity of records from several geographic areas within the country. To address these issues, we undertook a country-wide taxonomic revisionary study based on analysis of morphological variation, geographical distributions, and species ecologies. Observations were compiled in the field and herbarium. Shape analysis was performed using discriminant analysis. In the resulting taxonomic revision, we recognize six species of Aristolochia in Chile, including three new species, Aristolochia distorta, A. juntucha, and A. marinae, which are here described and illustrated. A neotype is designated for A. vaginans, and A. chilensis is placed in its synonymy. Aristolochia pearcei is treated as distinct from A. bridgesii based on discriminant analysis. All six species are considered endemic to Chile. Morphological descriptions, along with discussion of geographic distributions, taxonomy, and nomenclature, as well as preliminary conservation assessments are provided for all the treated species.
