abstract = {Blechnaceae, a leptosporangiate fern family nested within Eupolypods II, can be recognized by commissural veins parallel to the costae, cenosori borne on these commissural veins, indusia opening inwardly, and reddish young fronds and chromosome base number of 34. The family has been estimated to comprise 200-250 species, typically divided among seven to nine known genera. Despite recent molecular studies of the family, it still lacks a modern taxonomic update based on broad sampling from the two centers of diversity - neotropics and Australasia/Oceania. In order to test generic circumscriptions, we have assembled the broadest dataset thus far, from three plastid regions (rbcL, rps4-trnS, trnL-trnF) and with taxonomic sampling focused on both major diversity centers. Our sampling included 156 taxa and 178 newly generated sequences. We recognize three subfamilies each corresponding to a highly supported clade across all analyses (maximum parsimony, Bayesian inference, and maximum likelihood). The genera Salpichlaena, Stenochlaena, and Telmatoblechnum are monophyletic, while Blechnum, in its current circumscription, is polyphyletic, because Brainea, Doodia, and Sadleria all nest within it. }
