	abstract = {<p>Here we reconstruct the evolutionary history of Micromeria in the Canary Islands using eight nuclear markers. Our results show two centers of diversification for Micromeria, one in the eastern islands Gran Canaria and Lanzarote, the other in the western islands, Tenerife, La Palma and El Hierro. Suggested directions of inter-island colonization are the following: Gran Canaria to Lanzarote and La Gomera; Tenerife to La Palma (from the paleoisland of Teno), to El Hierro (from the younger, central part), and to La Gomera and Madeira (from the paleoislands). Colonization of La Gomera probably occurred several times from Gran Canaria and Tenerife. The taxonomic implications of these results are discussed. Incongruence among the different markers was evaluated and, using next generation sequencing, we investigated if this incongruence is due to gene duplication.</p>

	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>
