	abstract = {Micromeria Benth. (Lamiaceae, Nepetoideac) is a very common genus in the Mediterranean region. To test the monophyly of the genus and to elucidate its phylogenetic placement within subtribe Menthinae (Dumort) Endl, of tribe Mentheae Dumort we performed parsimony analysis of trnK intron sequence data of 51 accessions representing 15 genera of Nepetoideae and two genera of subfamily Ajugoideae. Tree topology reveals a well-supported "core group" indicating four distinct lineages. The first one comprises three species of Satureja L. s.str., the second one includes taxa of the genus Clinopodium L. from both the Old and the New World, paraphyletic with respect to Monarda L. and two species of Micromeria section Pseudomelissa Benth. A third group contains all samples of the remaining Micromeria species. Within this monophyly, a western lineage including taxa, from NW Africa, the Balearic, and the Canary Islands, is sister to an eastern lineage with species distributed from SE Asia to the western Mediterranean. In a further clade the genera Thymbra L., Thymus L., and Origanum L. are grouped together. Combined analysis using a reduced dataset of trnK/trnL-F sequences increased support for the infrageneric resolution within Micromeria. Based on the phylogenetic reconstructions there is evidence that the genus as currently circumscribed is polyphyletic. Results are discussed in the context of morphology, karyology, and biogeography, outlining the necessity of removing section Pseudomelissa from Micromeria.},

	abstract = {Phylogeny reconstruction at the species level, especially using organellar markers, is often complicated by problems such as incomplete lineage sorting and interspecific hybridization. Single-copy nuclear genes may be useful for these cases because they have higher mutation rates and are biparentally inherited. One plant group in which hybridization and incomplete lineage sorting have been proposed based on analyses of internal transcribed spacer (ITS) and plastid data is a clade of mints from the southeastern United States: Conradina and the related genera Dicerandra, Piloblepbis, Stacbydeoma, and Clinopodium (Lamiaceae). To clarify the phylogeny in this clade and investigate the possibility of incomplete lineage sorting and interspecific hybridization, we isolated three members of the nuclear GapC gene family and used two to reconstruct phylogeny. Separate phylogenetic analyses of the two GapC loci did not resolve species relationships. We then used two approaches to concatenate the two heterozygous GapC loci with ITS and plastid data sets from a previous study and carried out combined analyses. Trees resulting from the two concatenation approaches were similar in the resolution and support of generic relationships, but they differed drastically in resolution and support for relationships within Conradina. Conradina species are probably very recently derived, and it may be unreasonable to reconstruct species relationships in Conradina using DNA sequence data due to widespread hybridization or lack of coalescence. Rapidly evolving microsatellite data may be more useful for detecting hybridization and clarifying species boundaries in Conradina.},
