Figure 5From: Unraveling reticulate evolution in North American Dryopteris (Dryopteridaceae)Reticulation network showing hypothesized polyploidization events. Redrawn from the PADRE analysis of combined pgiC and gapCp dataset for North American allopolyploids and all other non-reticulate taxa included in the current study. Ploidy is indicated for allopolyploids; all other taxa are diploid (2x; see Table 2). Solid lines indicate the plastid lineage. Dotted lines indicate the paternal lineage as determined from nuclear sequence data. Taxa are colored as in Figures 1, 2 and 3.Back to article page
