Community phylogenomics of a rapid plant radiation: Pedicularis in the Hengduan Mountains.

The Hengduan Mountains of China on the eastern edge of the Tibetan plateau is one of the most diverse temperate plant communities in the world. Of the many clades that have diversified in situ in this region Pedicularis stands out for its exceptional diversity of floral forms displayed across >300 endemic species. A general link between floral diversity and species diversity has long been recognized within flowering plants, and the concentrated diversity of Pedicularis in the Hengduan Mountains provides an ideal system in which to investigate the role that interspecific reproductive interactions play in shaping this pattern. Over more than a decade of plant collecting expeditions we have developed a growing understanding of community compositions and patterns of genetic diversity within and between species. Here I share updates on ongoing efforts to characterize the drivers of diversification in Pedicularis from the perspectives of community assembly, parallel phylogeography, and genomic diversity.
