Figure 5.

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.
