Description
Summary:The woodwardioid ferns are well-represented in the Northern Hemisphere, where they are disjunctly distributed throughout the warm temperate and subtropical regions of North America, Europe, and Asia. To infer the biogeographic history of the woodwardioid ferns, the phylogeny of Woodwardia was estimated using rbcL and rps4 sequences from divergent distribution regions including the Himalayas. Phylogenetic results support Woodwardia as a monophyletic group with Woodwardia areolatae and W virginica as basal, these two species from eastern North America diverged early, which are sister clades to the remaining species from America, Europe, and Asia. Based on analyses of the fossil records of these species for divergence times, Woodwardia species were estimated to have diverged initially in the Paleogene of North America. After its New World origin, a greater diversification and expansion of Woodwardia occurred in eastern Eurasia, with the European arrival of Woodwardia radicans during the Middle Miocene. Compared to earlier reports, a migration back into North America via the Bering land bridge is consistent with these data.
