Plastid DNA variation in populations of 51 species of Knautia sect. Trichera based on petN(ycf6)-psbM sequences. a statistical parsimony network of the 97 plastid haplotypes encountered; numbering corresponds to Additional file 1: Table S1 (the numbers 1–57 correspond to diploid accessions from Rešetnik et al. [24]); the size of the circles is proportional to the square-root transformed frequency of the respective haplotype; haplotypes not sampled are shown as small black dots. Only haplotypes retrieved from at least two individuals as well as those mentioned in the text are labelled separately. Haplotypes present in diploids are identified by a black outline. bd geographic distribution of haplotypes. Symbols for the species are as in Fig. 1; their colour filling corresponds to the haplotype groups shown in a. The grey lines in b delimit three areas for which separate NeighbourNets of AFLP relationships complemented with plastid haplotypes are given in Figures S7–S9 within the Additional file 8
