Evolutionary history and biogeography of slipperflowers, Calceolaria (Calceolariaceae).

The genus Calceolaria (Calceolariaceae) is a New World species-rich genus involved in nectar-less oil-rewarding pollination interactions. Despite many attempts to clarify the phylogenetic relationships in the genus, they remain unresolved, hindering understanding the history of the group, the drivers of its diversification, and clarifying their taxonomy. Here, with the aim of resolving the phylogenetic relationships of the group, we sequenced the plastomes of 14 species sampled across the range and taxonomic sections of the genus. Along with establishing the plastome structure in these species, we show that our approach can resolve the backbone of the group with high support. Using this resolved phylogeny, we inferred the biogeographic history of the group, which illuminated a different scenario than the ones previously accepted. Our results demonstrate that increasing the locus sampling has the potential to resolve the history of the group, opening doors for its taxonomy, its spatial history, and the understanding of diversification along the Andes.
