Fig. 1 in High genetic and morphological diversification of the Euphorbia verrucosa alliance (Euphorbiaceae) in the Balkan and Iberian peninsulas

Fig. 1. Distribution of Euphorbia flavicoma (populations 1–43 in suppl. Table S1), E. verrucosa (44–113), E. serpentini (114–122) and E. montenegrina (123–146) sampled and used in this study. Black symbols indicate populations used in genetic (AFLP and/or ITS) and mostly also in relative genome size (RGS) and morphometric analyses, grey symbols indicate additional populations used in RGS and/or morphometric analyses. White dots within some symbols of E. flavicoma and E. montenegrina indicate tetraploid populations (all other populations, for which RGS was measured, were diploid). The asterisk within one circle indicates the population from Puy du Wolf in southern France, which was described as E. flavicoma subsp. costeana, but actually belongs to E. verrucosa.
