Adventures in plant phylogeny: circling back to Viburnum


After a long hiatus, I returned recently to working on the evolution and biogeography of Viburnum, a widespread group of woody flowering plants. By way of framing several of our recent Viburnum studies, I will briefly mention some of our old and new findings on seed plants, angiosperms, campanulids, and dipsacales. Then I will focus on the historical biogeography of Viburnum, and describe two studies in some detail: one on leaf form and another on extrafloral nectaries and domatia. I hope that these studies will illustrate the special value of well-sampled phylogenetic trees and the benefits of paying close attention to a group of organisms over a long period of time
