Systematics Section/ASPT Ree, Richard [1], Kuss, Patrick [2]. Global phylogeny of Pedicularis (Orobanchaceae) and its radiations across the Northern Hemisphere. Large and widepread radiations are challenging for systematic analysis, particularly when significant numbers of species occur in inaccessible locales and are poorly represented in herbaria, with fragmentary taxonomic knowledge and uncertain numbers and limits of species. Such is the case for Pedicularis: it provisionally includes over 700 species distributed throughout the Northern Hemisphere, mainly in the mountains of eastern and central Asia. Over the past several years, we have assembled a global multigene dataset representing more than 450 species and 1200 sequenced voucher specimens, the most comprehensive sampling to date of this group. The resulting phylogeny has little congruence with previous infrageneric classification schemes, but reveals many biogeographic patterns indicating repeated radiations associated with movements throughout the Northern Hemisphere.
