Figure 4.

Medium-Joining Network (A) and unrooted NJ tree (B) of 13 cpDNA haplotypes (dH1-13) across 34 individuals of 18 populations of the diploid species of A. millefolium agg. and the congeneric A. ligustica-2x. These haplotypes are generated from three noncoding cpDNA regions, trnH-psbA, trnC-ycf6 and rpL16. Short bars on branches of the network indicate the number of variable sites (incl. gap polymorphisms, see Table 2). Red numbers next to the branches of the NJ tree are bootstrap values. Plant individuals are labelled as "taxa abbreviation (population code-individual identity No.)". For taxa abbreviations, see Table 1.
