摘　　要：Fumana is a diverse genus of the Cistaceae family,consisting of 21 currently accepted species.In this study,nuclear(ITS)and plastid(matK,trnT-L)molecular markers were used to reconstruct the phylogeny and to estimate divergence times,including 19 species of Fumana.Phylogenetic analyses(Bayesian Inference,Maximum Parsimony and Maximum Likelihood)confirmed the monophyly of Fumana and did not support the infrageneric divisions previously established.The results support four main clades that group species that differ in vegetative and reproductive characters.Given the impossibility to define morphological characters common to all species within the clades,our proposal is to reject infrageneric divisions.Molecular dating and ancestral area analyses provide evidence for a Miocene diversification of the genus in the north-western Mediterranean.Ancestral state reconstructions revealed ancestral character states for some traits related to xeric and arid habitats,suggesting a preadaptation to the Mediterranean climate.
