Two-dimensional mapping of AFLP-based Euclidean distances using EUKLID. A:Potentilla pusilla, diploid, and hexaploid P. argentea, and the combined group Aureae Frigidae (P. brauneana, P. frigida)/Aureae Alpestres (P. aurea, P. crantzii) are reference groups located at the outer limits of the plot. The putative hybrids P. alpicola (lineages a–c) and P. collina are placed at an approximately intermediate position between P. pusilla and hexaploid P. argentea. B: Graphical representation of the genetic relationships of P. alpicola lineage a and lineage c to the reference taxa P. pusilla, hexaploid P. argentea, and P. alpicola lineage b (see text for details). The mapping error of the two-dimensional presentations is 0.187 (a) and 0.083 (b), respectively.
