Phylogenetic relationships within the Euphorbia nicaeensis alliance and between this alliance and its closest relatives within E. sect. Pithyusa as inferred by Internal Transcribed Spacer (ITS) sequences. (A) Bayesian consensus phylogram with posterior probabilities > 0.50 above, and parsimony bootstrap values > 50% below branches; country codes follow the accession names. (B) NeighborNet and (C) geographic position of the ITS ribotype groups revealed by the NeighborNet and indicated by different colours. Population numbers in (A,B) are presented in Supplementary Figure 1 and in Supplementary Table 1. Population numbers of populations that are based on our revised taxonomic treatment belong to E. adriatica and are in (B) in bold italics (45, 47, 59, 63), and the one corresponding to E. japygica (58) is in bold. (D) Euphorbia adriatica from Italy and (E) E. macroclada from Turkey in their natural habitats. Photos: B. Frajman (D), C. Gilly (E).
