	abstract = {<p>Premise of the study: The mint family (Lamiaceae) is the sixth largest family of flowering plants, with the tribe Mentheae containing about a third of the species. We present a detailed perspective on the evolution of the tribe Mentheae based on a phylogenetic analysis of cpDNA and nrDNA that is the most comprehensive to date, a biogeographic set of analyses using a fossil-calibrated chronogram, and an examination of staminal evolution. Methods: Data from four cpDNA and two nrDNA markers representing all extant genera within the tribe Mentheae were analyzed using the programs BEAST, Lagrange, S-DIVA, and BayesTraits. BEAST was used to simultaneously estimate phylog- eny and divergence times, Lagrange and S-DIVA were used for biogeographical reconstruction, and BayesTraits was used to infer staminal evolution within the tribe. Key results: Currently accepted subtribal delimitations are shown to be invalid and are updated. The Mentheae and all five of its subtribes have a Mediterranean origin and have dispersed to the New World multiple times. The vast majority of New World species of subtribe Menthinae are the product of a single dispersal event in the mid-late Miocene. At least four transitions from four stamens to two stamens have occurred within Mentheae, once in the subtribe Salviinae, once in the subtribe Lycopinae, and at least twice in the subtribe Menthinae. Conclusions: Worldwide cooling trends probably played a large role in the diversification and present day distribution of the tribe Mentheae. Additional work is needed to ascertain relationships within some Mentheae genera, especially in the subtribe Menthinae.</p>

	title = {A new synonym of Lepechinia (Salviinae: Lamiaceae)},

	pages = {52},
	abstract = {Chaunostoma Donnell Smith (1895: 9) and Lepechinia Willdenow (1804: 20, pl. 21) belong to the subtribe Salviinae of the Lamiaceae (Harley et al. 2004). Chaunostoma is known as a monotypic genus and is restricted to South Mexico (Chiapas) and Guatemala. However, the generic delimitation of Chaunostoma has been questioned because of the close relationship with Lepechinia, which includes ca. 40 species and is mainly distributed from Argentina to Mexico and Northern California (Epling 1948). In fact, Chaunostoma differs from Lepechinia only by cauliflorous inflorescences and the arched stamens (Epling 1948, Harley et al. 2004). Nevertheless, since the arched stamens can also be found in Lepechinia (Epling 1948, Walker {\&} Sytsma 2007), the generic status of Chaunostoma has become increasingly problematic within Salviinae. Following a recent phylogenetic study, Chaunostoma and Lepechinia are considered together as a monophyletic group within Salviinae (Drew {\&} Sytsma 2011). The micromorphological characteristics of these two genera support the same conclusions as the molecular phylogeny. For example, Chaunostoma and Lepechinia produce perforate pollen grains while the other members of Salviinae possess bireticulate pollen grains (Moon et al. 2008). Moreover the areolate abscission scar of the nutlets is a synapomorphic condition for Chaunostoma and Lepechinia (Moon et al. 2009). Therefore, the new synonym and the necessary combination are proposed here.},

	abstract = {An earlier molecular study demonstrated the monophyly of the Hyptidinae and most of the genera within it. However, the largest genus, Hyptis, is paraphyletic and all other genera seem to be derived from a Hyptis ancestor. Most of the different lineages which comprise Hyptis are already established sections, some of which are now raised to generic rank, augmenting the subtribe to 19 genera and with a greatly reduced but monophyletic Hyptis, in which the genus Peltodon is included as a section. The sections Mesosphaeria and Polydesmia are also shown not to be monophyletic, making it necessary to reassign some species from the former to the latter, and then raising the two sections to generic rank as Mesosphaerum and Cantinoa respectively, the latter a new genus name. A new genus Oocephalus is also created from two former subsections of Hyptis sect. Polydesmia. The genus Condea, formed from three former sections of Hyptis, is itself divided into two sections. A key to all recognized genera is included, together with a generic conspectus, with brief distributional data, differentiating the new genera and listing their component species. The necessary nomenclatural changes comprise 142 new combinations, 30 new or replacement lectotypifications, four neotypes, 23 new synonymies, eight stat. nov., six newly coined generic names, five new epitypes and four new names.},
