Differential diversifications of South American and Eastern Asian disjunct genera Bocconia and Macleaya (Papaveraceae)
Abstract Bocconia (10 species) and Macleaya (2 species) are two disjunct genera between South America and eastern Asia (EAS) in the Papaveraceae offering an opportunity to compare its biogeographic history with that of the well‐known disjunction between EAS and eastern North American (ENA).
