The evolutionary history of this tribe was reconstructed based on ITS and trnL-trnF spacer sequence data of 71 species, representing. 47 out of 65 genera. The resulting phylogeny was used to analyse the distribution of selected morphological characteristics such as sexine ornamentation of pollen, nutlet shape with existence of abscission scar and its form, and trichome types. Two monophyletic groups are recognized, which largely correspond to the current subtribal circumscription. Subtribe Salviinae is monophyletic, including the genus Melissa which was a genus of uncertain affinity in Mentheae. Subtribe Menthinae is not monophyletic since Cleonia, Horminum, Hyssopus, Lycopus and Prunella are more closely related with subtribe Nepetinae. Although we could not detect any morphological synapomorphies for each clade, morphological variation seems to be correlated with the molecular phylogeny. A circular abscission scar without distinct lateral areole occurred mainly in Salviinae, while the majority of the species of Mentheae and Nepetinae had a clear areole at the abscission scar. In addition, a reticulate sexine ornamentation is rather common in the Menthinae clade.}, keywords = {Anatomy, Dna, Evolution, Inference, Labiatae, Lamiaceae, Mentheae, Micromorphology, Morphology, Nepetoideae Lamiaceae, Phylogeny, Salvia Lamiaceae, Sequence Data, Verbenaceae}, author = {Hye-Kyoung Moon and Erik Smets and Suzy Huysmans} } @article {ElOualidi:1999p704, title = {Utility of rDNA ITS sequences in the systematics of Teucrium section Polium (Lamiaceae)}, journal = {Plant Syst Evol}, volume = {215}, number = {1-4}, year = {1999}, month = {Jan}, pages = {49{\textendash}70}, abstract = {A phylogenetic study based on sequence data from the complete internal transcribed spacer region (ITS) of nuclear ribosomal DNA for sect. Polium of the genus Teucrium shows both intersectional congruence and intrasectional incongruence with traditional morphological classifications. We attribute this incongruence largely to problems related to the polyploid complex studied. Section Polium includes many poorly differentiated taxa of probable recent origin through hybridization followed by polyploidization. Both on the basis of parsimony and distance (Neighbor-Joining method) analyses, T. dunense and T. thymifolium are the species that diverge most from the sampled taxa. However, unlike T. thymifolium, the morphology of ir: dunense is not much differentiated in relation to the other taxa. Both species are, nonetheless, the only sampled species to occupy isolated, exclusive environments and which may have undergone rapid evolution by a bottleneck effect. Teucrium dunense is found only on dunes along the Spanish and French coasts and ir: thymifolium, a chasmophytic species with limited endemism, is found solely on limestone and dolomite cliffs in the low mountains in south-eastern Spain. A hypothesis is presented to explain the discrepancy between the observed comparatively large amount of ITS sequence divergence and the low morphological differentiation in T. dunense.}, keywords = {Evolution, Internal Transcribed Spacer Region (Its), Labiatae, Lamiaceae, Nuclear Ribosomal Dna, Nucleotide-Sequences, Phylogenetic Analysis, Phylogeny, Polyploid Complex, Populations, Rbcl, Sect.
