	abstract = {<p>The phenomenon of polyploidy and hybridization usually results in novel genetic combinations, leading to complex, reticulate evolution and incongruence among gene trees, which in turn may show different phylogenetic histories than the inherent species tree. The largest tribe within the subfamily Lamioideae (Lamiaceae), Stachydeae, which includes the globally distributed Stachys, and one of the largest Hawaiian angiosperm radiations, the endemic mints, is a widespread and taxonomically challenging lineage displaying a wide spectrum of morphological and chromosomal diversity. Previous molecular phylogenetic studies have showed that while the Hawaiian mints group with Mexican-South American Stachys based on chloroplast DNA sequence data, nuclear ribosomal DNA (nrDNA) sequences suggest that they are most closely related to temperate North American Stachys. Here, we have utilized five independently inherited, low-copy nuclear loci, and a variety of phylogenetic methods, including multi-locus coalescence-based tree reconstructions, to provide insight into the complex origins and evolutionary relationships between the New World Stachys and the Hawaiian mints. Our results demonstrate incongruence between individual gene trees, grouping the Hawaiian mints with both temperate North American and Meso-South American Stachys clades. However, our multi-locus coalescence tree is concurrent with previous nrDNA results placing them within the temperate North American Stachys clade. Our results point toward a possible allopolyploid hybrid origin of the Hawaiian mints arising from temperate North American and Meso-South American ancestors, as well as a reticulate origin for South American Stachys. As such, our study is another significant step toward further understanding the putative parentage and the potential influence of hybridization and incomplete lineage sorting in giving rise to this insular plant lineage, which following colonization underwent rapid morphological and ecological diversification.</p>

	abstract = {Lamioideae comprise the second-largest subfamily in Lamiaceae. 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.},
