These files are part of the results of a biogeographic research about the potential and real distribution of Passiflora ischnoclada Harms. We started with a single known occurrence point for the species, from where an environmental dissimilarity model was generated to guide new fieldwork. Other models were generated as more points were found, until a final consensus model was generated using 5 algorithms. This final model was used to estimate the real distribution of the species.
