eprea is the genus with the second highest species richness in tribe Physalideae (Solanaceae) and comprises 50 species that are mainly distributed in the Andes of South America. The taxonomy of Deprea has been unstable after controversial hypotheses about its position and circumscription. Additionally, biogeographical inferences are only based on observations of the restricted area of distribution of some species and no ancestral area estimation have been performed. Here, we present a phylogenetic analysis and an ancestral area reconstruction of Deprea in order to establish its circumscription, resolve its position within Physalideae, and reconstruct its biogeographical history. Phylogenetic analyses were conducted using Maximum Likelihood and Bayesian approaches. Forty-three Deprea species and 26 related taxa were sampled for three DNA markers (psbA-trnH, ITS, and waxy). A Bayesian binary MCMC model was applied in order to infer ancestral areas. Deprea is resolved as a strongly suppo
