	abstract = {The phylogenetic relationships of the 16 species of Monarda (Lamiaceae) were investigated using sequences of the internal transcribed spacer regions of nuclear ribosomal DNA. Thymus and Mentha were used as outgroups, and Blephilia, Clinopodium, Conradina, Hesperozygis, Monardella, Pycnanthemum, and Ziziphora were included in the ingroup to test the monophyly of Monarda. Two parsimony searches were performed after removing redundant sequences from the analysis: one with indels scored as missing and a second with indels treated as binary characters, Both searches yielded congruent results, but the treatment of indels as binary characters resulted in considerably more resolution within Monarda. There was strong support for the monophyly of Monarda and a close relationship was found between Monarda, Blephilia, and Pycnanthemum. The molecular phylogeny was completely congruent with the infrageneric classification of the genus. Our results were consistent with hypotheses of hybridization between M. fistulosa and M. lindheimeri in Texas. Despite considerable morphological variation among many species, especially in floral characters, little molecular diversification was found in those same species groups. Intraspecific polymorphism in ITS sequence was found in over half the species examined, and may be attributable to ancestral polymorphism, hybridization, or detection of paralogous loci.},

	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.},

Menthinae pollen is small to medium in size (13-43 mu m), oblate to prolate in shape and mostly hexacolpate (sometimes pentacolpate). Perforate, microreticulate or bireticulate exine ornamentation types were observed. The exine ornamentation of Menthinae is systematically highly informative particularly at generic level. The exine stratification in all taxa studied is characterized by unbranched columellae. Orbicules are consistently absent in Menthinae. Our palynological data are interpreted in a phylogenetic context at tribal level in order to assess the systematic value of pollen characters and to evaluate the existing molecular phylogenies for this group. Pollen morphology suggests Heterolamium as a close relative of subtribe Nepetinae and supports the molecular affinity of Melissa to subtribe Salviinae.},

	abstract = {Bystropogon (Lamiaceae) is endemic to the Macaronesian Islands and represents the best-known example of a putative phytogeographic connection between these islands and the New World. Previous morphological taxonomic studies suggested that this genus is closely related to the western South American Minthostachys. Phylogenetic analyses of nucleotide sequences of the internal transcribed spacers and 5.8S subunit of nuclear ribosomal DNA and the trnL gene and trnL-trnF spacer of the chloroplast genome for 33 of the 72 genera in the Mentheae tribe were performed. Maximum parsimony analysis of the combined data set resulted in 63 most parsimonious trees. The strict consensus tree of this analysis shows with moderate bootstrap support (74\%) that Bystropogon is sister to the Old World taxa Acinos, Ziziphora, and Clinopodium vulgare. When analyzed separately, the ITS and trnL/F data sets do not agree as to the sister group to Bystropogon, although none supports a sister relationship with Minthostachys. The cpDNA phylogeny strongly supports a relationship of Bystropogon with a clade of New World mint taxa (90\% bootstrap value). Due to the apparent conflict between the chloroplast and nuclear characters observed in the phylogenies, we are not certain of the true biogeographic relationship of Bystropogon. Finally, in all analyses, all of the Mentheae genera sampled in this study form a monophyletic group (100\% bootstrap value) and a derived clade of ten New World genera is found. These results contribute to our understanding of generic relationships within the tribe.},

Lamioideae (including subfamily Pogostemonoideae) based on sequences of the trnL intron, trnL-trnF intergenic spacer, and rps16 intron of the plastid genuine. It is the first analysis that includes all major lamioid and pogostemonoid genera. Monophyly of Lamioideae s.l. (i.e., including Pogostemonoideae) is strongly supported, with Cymaria Benth. as its sister group, and Pogostemonoideae, which sometimes has been recognized as a subfamily, is subsumed in Lamioideae. On the basis of the phylogenetic hypothesis, Lamioideae is divided into nine tribes. Three new tribes are established: Gomphostemmateae Seheen {\&} Lindqvist, Phlomideae Mathiesen, and Leucadeae Scheen {\&} Ryding. The other six tribes are: Pogostemoneae Briq., Synandreae Raf., Staehydeae Dumort., Leonureae Dumort., Limieae Coss. {\&} Germ., and Marrubieae Vis. The genus Betonica L. is reestablished. The results also strongly suggest that the genera Stachys L., Sideritis L., Ballota and Leucas R. Br. are polyphyletic or paraphyletic. The results were used to examine evolution of non-molecular characters.},
