Figure 2.

Unrooted Neighbour Joining phylogram of 10 diploid Achillea species (seven of and three outside A. millefolium agg.) based on the SBP gene sequence data. The tree contains 21 SBP haplotypes generated from 163 clones (sequences) from 35 individuals of 19 populations. Bootstrap supports (> 50%) from both methods (NJ/MP) are shown next to the major branches. Labels of terminal branches are written as "taxon abbreviation (population code-number of individuals/number of clones)". For taxa abbreviations, see Table 1.
