Fig. 2 in High genetic and morphological diversification of the Euphorbia verrucosa alliance (Euphorbiaceae) in the Balkan and Iberian peninsulas
Fig. 2. ITS variation in Euphorbia flavicoma, E. montenegrina, E. serpentini and E. verrucosa. NeighborNet of ITS sequences (A) and geographic position of the ITS ribotype groups revealed by the NeighborNet (B). The asterisk in (A) denotes the population 116 of E. serpentini, which had the same ribotype as several populations of E. montenegrina; for better visibility, the symbols for both species are thus slightly displaced in the NeighborNet.
