Fig. 3. Phylogenetic relationships among Euphorbia flavicoma, E. montenegrina, E. serpentini and E in High genetic and morphological diversification of the Euphorbia verrucosa alliance (Euphorbiaceae) in the Balkan and Iberian peninsulas

Fig. 3. Phylogenetic relationships among Euphorbia flavicoma, E. montenegrina, E. serpentini and E. verrucosa inferred by neighbour-joining analysis based on AFLP fingerprinting and presented in detail in supplementary Fig. S3. Terminals belonging to the same taxa/ploidy levels were collapsed; the heights of the triangles correspond to the number of individuals analysed. Numbers above branches are bootstrap values, and 2x and 4x indicate diploid and tetraploid ploidy levels, respectively. Within E. montenegrina, both ploidy levels appeared in several clusters.
