	abstract = {Mentheae are the largest tribe in the family Lamiaceae and economically important, including herbs like mint, sage and thyme. 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.},

	abstract = {A comparative micromorphological study of leaves was carried out on 102 species of Mentheae; 61 species were selected for the anatomical study. Mentheae possessed both amphistomatic and hypostomatic leaves. The diversity of leaf epidermal characteristics was based on the variation in morphology of epidermal cells, stomata types and trichome types. Although each characteristic on its own has rather limited systematic value, the combination of some of these features may be systematically relevant, especially for the identification of species. For example, branched multicellular nonglandular trichomes were a diagnostic characteristic for all genera investigated of the subtribe Salviinae; however, this trichome type was also observed in Hedeoma ciliolata and Neoeplingia leucophylloides of the subtribe Menthinae. Capitate glandular trichomes with pear-shaped heads were only observed in Salvia dorrii. Subsessile glandular trichomes with multicellular heads (more than ten cells) were an apomorphy for Perovskia. The anatomical leaf structure was consistent throughout the tribe. In some species, the vascular bundles in the midrib were modified into a mechanical tissue, which is an adaptation to xerophytic environments. The observed variations are discussed in an ecological context and their phylogenetic significance is evaluated.
