In connection with our development of Viburnum (Adoxaceae) as a model lineage for studies of plant evolution and ecology, we have inferred a comprehensive dated phylogeny based on multiple lines of evidence.  Jointly with our phylogenetic inference, we have estimated past geographic movements and shifts between mesic forest biomes.  This provides us with reliable estimates for movements within and between continents throughout the Cenozoic, as well as for multiple instances of adaptation to colder climates.  Much of the action took place in Asia, with&nbsp
