Fig. 9From: Osmunda pulchella sp. nov. from the Jurassic of Sweden—reconciling molecular and fossil evidence in the phylogeny of modern royal ferns (Osmundaceae)Placement of fossil and extant members into the specified backbone topology of modern Osmundaceae inferred from molecular data of Metzgar et al. [32] using the evolutionary placement algorithm [147] (see Additional file 1 [ESA]) and three different character-weighting schemes. Dashed light-grey lines indicate weighting-scheme-dependent position swaps of taxa. Abbreviations: MLGTR = weighting scheme optimized under a general-time reversible transformation model; MLMK, weighting scheme optimized under Lewis’ (2001) model; MP = weighting scheme under parsimonyBack to article page
