We analysed AFLP markers with four primer pairs and scored 203 polymorphic fragments in 59 Spiraea clones, representing 32 taxa (23 species) from all four currently recognized sections (Spiraea, Calospira, Chamaedryon and Sciadantha). We also included intra- and intersectional cultural hybrids from S. section Spiraea, S. section Spiraea x section Calospira and S. section Spiraea x section Chamaedryon. In total, 161 morphological traits and AFLP data were analysed for 34 taxa using three phylogenetic methods to test the hypothesis of a non-natural concept of an infrageneric division of Spiraea in the current sections and their inadequate delimitation. Phylogenetic parsimony, Bayesian analysis and neighbour network revealed four main groups corresponding to the principal coordinate analysis. The genetic relationships between significant species of Spiraea and its phylogeny, as inferred from AFLP data, are not compatible with the principle of gradual variation in inflorescence and shoot morphology used in the previously published infrageneric divisions at the level of subgenera and sections.
