Palicourea is a species-rich genus of Neotropical plants in the family Rubiaceae. It consists of >800 species (several species of Psychotria are now transferred to the group) with center of diversity in South and Central America. Palicourea includes predominantly shrubs and subshrubs living in habitats that range from lowland to montane, and from seasonal to usually wet ecosystems. The genus is remarkable for its diverse inflorescence and flower morphology ranging from small white flowers that are pollinated by insects, to colored flowers, with well-developed corolla tubes, and abundant nectar that are hummingbird pollinated. In this project we inferred evolutionary relationships of Palicourea using a target enrichment approach with recently developed probes for Rubiaceae. Our species tree is the most comprehensive phylogenetic study of the group to date, both in terms of genomic and taxon coverage. We modeled biogeographic range evolution in Palicourea and estimated climatic niche overlap of species pairs to propose hypotheses for the interplay between floral, geographic, and niche evolution in this diverse group of Neotropical plants. Stay tuned for what we find and present!
