Together with the monotypic European genus Melittis and the Asian genus Chelonopsis, these taxa have been classified as subtribe Melittidinae. Previous morphological studies have failed to uncover synapomorphic characters for this group. We sequenced the plastid trnL-trnF region and trnS-trnG spacer and the nuclear ribosomal 5S non-transcribed spacer (5S-NTS) to assess phylogenetic relationships within Melittidinae. Standard parsimony and direct optimization (POY) analyses show Melittis, the type genus of the subtribe, as sister to Stachys. Thus, the monophyly of subtribe Melittidinae is not supported either by molecular or morphological data. However, the North American endemics form a monophyletic group that can be recognized as the recircumscribed tribe Synandreae. The molecular relationships among these genera are corroborated by both morphological and cytological data. The expected close relationship between the south-central endemics Warnockia and Brazoria and their sister relationship to the widespread genus Physostegia is confirmed. Nevertheless, most of the North American endemics are restricted to the south-east of the continent. Dispersal westwards and northwards is correlated with an increase in chromosome numbers. No specific Eurasian origin (i.e., transatlantic or transpacific) can be determined, but Synandreae are clearly distinct from the large Stachys clade, and therefore represent a separate migration into North America.

Although considerable progress has recently been made in Lamioideae phylogenetics, the subfamily remains one of the most poorly investigated subfamilies in Lamiaceae. Here we present a taxonomic update of the subfamily based on earlier published data as well as 71 new DNA extracts from relevant in- and outgroup taxa, and DNA sequence data from four chloroplast regions (matK, rps16, trnL intron and trnL-F spacer). The phylogenetic positions of 10 out of 13 previously unplaced small or monotypic Asian lamioid genera and 37 additional lamioid species have been identified, and the classification is updated accordingly. Results from parsimony and Bayesian phylogenetic methods corroborate earlier results, but phylogenetic resolution as well as overall branch support are improved. All newly added genera are assigned to earlier established tribes or the new tribe Paraphlomideae Bendiksby, which includes Ajugoides, Matsumurella and Paraphlomis. Acanthoprasium is resurrected as a genus. Transfer of species is proposed to accommodate the monophyly of two genera (Lamium, Otostegia), whereas ten genera remain non-monophyletic (Ballota s.str., Lagopsis, Leonotis, Leonurus, Leucas, Microtoena, Phlomoides, Sideritis, Stachys, Thuspeinanta). Eriophyton and Stachyopsis have been included in Lamieae, Hypogomphia in Stachydeae, and Loxocalyx in Leonureae. Betonica, Colquhounia, Galeopsis, and Roylea remain unclassified at the tribal level. Lamium chinense and three East Asian Galeobdolon species are transferred to Matsumurella. Sulaimania and four Otostegia species are transferred to Moluccella. Alajja and three Lamium species are transferred to Eriophyton. In total, 14 new combinations are made, one at the rank of subgenus and 13 at the rank of species.}, keywords = {Acanthoprasium, Chloroplast Sequence Datasets, Classification, Dna, Eriophyton, Evolution, Hawaiian Endemic Mints, Labiatae, Lamiaceae, Lamioideae, Matsumurella, Molecular Phylogenetics, Moluccella, Nuclear, Origin, Paraphlomideae, Pericarp Structure, Sideritis Lamiaceae}, url = {http://apps.webofknowledge.com/InboundService.do?SID=2B\%2540kNem2NICHnHfl3PI\&product=WOS\&UT=000289587100015\&SrcApp=Papers\&DestFail=http\%253A\%252F\%252Faccess.isiproducts.com\%252Fcustom_images\%252Fwok5_failed_auth.html\&Init=Yes\&action=retrieve\&SrcAuth=meken}, author = {Mika Bendiksby and Lisbeth Thorbek and Anne-Cathrine Scheen and Charlotte Lindqvist and Olof Ryding} } @article {Scheen:2010p3190, title = {MOLECULAR PHYLOGENETICS, CHARACTER EVOLUTION, AND SUPRAGENERIC CLASSIFICATION OF LAMIOIDEAE (LAMIACEAE)}, journal = {Annals of the Missouri Botanical Garden}, volume = {97}, number = {2}, year = {2010}, month = {Jan}, pages = {191{\textendash}217}, abstract = {This paper presents a phylogenetic analysis of Lamiaceae subfam. 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.
