Abstract:
Genus Sideritis is ranged in Western Palaearctic by 193 species classified into two subgenus and seven sections. Its species diversity mainly concentrated in Mediterranean basin. The subgenera and sections in the genus were established by traditional taxonomy and their monophyly has not been tested. Using 19 representative species from seven sections belonging to subgenera Sideritis and Marrubiastrum we aimed to test monophyly of the subgenera. We defined and coded 26 morphological characters and applied a parsimony analysis choosing a Stachys sp. as outgroup. The majority rule consensus tree of the 9 equally parsimonious trees suggested the following relationships: ((((((S. montana + (S. lanata + S. romana) + (S. barbellata + (S. discolor + S. cretica + (S. macrostachys + (S. nutans + S. gomerae))))) + S. stachydioides) + S. scardica) + S. condensata + (S. siplylea + (S. cilicica + (S. hyssopifolia + (S. glacialis + (S. osteoxylla + S. bourgeana)))))) + S. syriaca) + Stachys sp.. In the light of these data, the following main conclusions were raised: (i) Neither subgenera nor sections in the genus Sideritis are monophyletic, (ii) most of characters that were used for descriptions of subgenera and sections are homoplastic and (iii) as species in the Empedoclia section occupy the basal branches of the each main clades possibly this section represent ancestor
