Several methods were used to reconstruct phylogenies and to assess statistical support for clades: maximum parsimony with equally and successively weighted characters, bootstrap resampling, and Bayesian inference. The phylogeny is used to investigate the distribution of morphological, pericarp anatomy, chemical, and pollen characters as well as the geographical distribution of the clades. Tribe Ocimeae is monophyletic and easily diagnosable with morphological synapomorphies. There are monophyletic clades within Ocimeae that broadly correspond to currently recognised subtribes; Lavandulinae, Hyptidinae, Ociminae, and Plectranthinae. Only Lavandulinae has clear non-molecular synapomorphies. Several currently recognised genera are not monophyletic. Floral morphology consistent with sternotribic pollination is most common in Ocimeae, but there are independent departures from this model. Buzz pollination is likely in some species, the only postulated occurrence of this within Lamiaceae. Quinone diterpenoids and flavones in the leaf exudates differ in their distributions across the phylogeny and this could contribute to differences in the recorded medicinal as well as pesticidal uses of the species in the different clades. Mapping geographic distribution on to an ultrametric phylogenetic tree produced using non-parametric rate smoothing supports an Asiatic origin for Ocimeae. There are several secondary occurrences in Asia arising from the African Ociminae and Plectranthinae clades. Colonisation of Madagascar occurred at least five times, and New World colonisation occurred at least three times. (C) 2003 Elsevier Inc. All rights reserved.

(Lamiaceae) comprises approximately 150 species of annuals and perennials distributed chiefly in the Mediterranean region. The majority of the species belong to the continental subgenus Sideritis which is divided into two perennial (Sideritis and Empedoclea) and two annual (Hesiodia and Burgsdorfia) sections. Twenty-three species are woody perennials endemic to the Macaronesian archipelagos of Madeira and the Canary Islands. In an effort to determine the continental origin of the insular group, we constructed independent phylogenies comprising sequence data from both chloroplast and nuclear markers. Sampling included 7 island taxa drawn from the Macaronesian subgenus Marrubiastrum and 25 continental taxa representing all four sections of subgenus Sideritis. Subgenus Marrubiastrum and the two continental perennial sections form well-supported monophyletic groups in both individual and combined analyses. The annual sections are not monophyletic in any analysis; further sampling of annual taxa is needed to resolve these relationships. All analyses identified Sideritis cossoniana, an annual species from Morocco, as the closest continental relative of the Macaronesian group. This contrasts with the hypothesis of earlier workers who suggested that the insular taxa were most closely related to eastern Mediterranean species of the genus. The phylogenies also demonstrate a distinct increase in woodiness among the Macaronesian species relative to their continental congeners, providing further support for the secondary nature of woodiness in island plants.

With the development of molecular methods for systematic research the process of circumscribing taxa has become increasingly analytical. When morphology signals the possibility that taxa are closely related, molecular methods can be used to test the hypothesis objectively. Aegiphila, Amasonia, Huxleya, and Kalaharia are similar morphologically to Clerodendrum. In this paper we use nuclear ribosomal ITS and chloroplast ndhF sequence data to clarify the positions of these four genera relative to Clerodendrum. We show that the Australian monotypic genus Huxleya evolved from within Clerodendrum. Accordingly, we sink Huxleya into Clerodendrum and make a new combination, Clerodendrum linifolium.

DNA sequence data from three regions (chloroplast: trnK intron; trnL-F; nuclear: ITS) in total including 278 accessions, representing 38 out of 40 genera of subtribe Menthinae and 11 outgroup genera, were used to reconstruct the evolutionary history, test previous hypotheses of classification, explain biogeographic patterns and elucidate character evolution. Using maximum parsimony (MP) and Bayesian analysis phylogenetic reconstructions based on nuclear and chloroplast sequence data were incongruent, consequently the data were analyzed separately.Both nuclear and chloroplast datasets provide strong support for three major lineages: the "Satureja", "Micromeria" and "Clinopodium" group. The first contains members of Satureja and Gontscharovia. In the second lineage Micromeria s.str. and Origanum were resolved as monophyletic, Pentapleura and Zataria indicated as sister groups. Thymbra includes two species of Satureja turning the latter genus polyphyletic. Thymus is revealed as paraphyletic with respect to Argantoniella and Saccocalyx in both and Origanum in the plastid dataset only. In the third lineage, the Clinopodium-group, branching pattern is highly incongruent among datasets and possibly influenced by recent and ancient hybridization, chloroplast capture and incomplete lineage sorting. However, identical terminal groups are inferred in both analyses. A Madagascan lineage of "Micromeria", sister to the recently described South African Killickia, is suggested to represent a new genus. The Himalayan Clinopodium nepalense group and the tropical African C. abyssinicum alliance are monophyletic but indicated in different positions. Both groups appear in the ITS phylogeny in a clade with Cyclotrichium and Mentha, relationships not suggested previously. The enigmatic Micromeria cymuligera is close to Mentha and possibly is a representative of this genus. Species of Acinos, now regarded as part of Clinopodium, are mixed up with species of Ziziphora, questioning either the inclusion of Acinos in Clinopodium or generic distinctness of Ziziphora. All data sets suggest a monophyly of the New World taxa and argue for long distance dispersal from the Old World, rather than a vicariance explanation. Bystropogon marks the split up between the two lineages. Inclusion of 22 genera intermixed with Clinopodium spp. in the New World clade provides evidence that the current circumscription of the genus is highly unnatural. Low sequence divergence resulting in low phylogenetic resolution especially at the base of the clade indicate a rapid radiation accompanied by considerable ecological diversification and speciation.

Based on phylogeographic patterns, both inter island colonization and adaptive radiation seem to be the driving forces for speciation in most taxa. Here, we investigated the diversification of Micromeria on the Canary Islands and Madeira at the inter- and infraspecific level using inter simple sequence repeat PCR (ISSR), the trnK-Intron and the trnT-trnL-spacer of the cpDNA and a low copy nuclear gene. The genus Micromeria (Lamiaceae, Mentheae) includes 16 species and 13 subspecies in Macaronesia. Most taxa are restricted endemics, or grow in similar ecological conditions on two islands. An exception is M. varia, a widespread species inhabits the lowland scrub on each island of the archipelago and could represent an ancestral taxon from which radiation started on the different islands. Our analyses support a split between the "eastern" islands Fuerteventura, Lanzarote and Gran Canaria and the "western" islands Tenerife, La Palma and El Hierro. The colonization of Madeira started from the western Islands, probably from Tenerife as indicated by the sequence data. We identified two lineages of Micromeria on Gomera but all other islands appear to be colonized by a single lineage, supporting adaptive radiation as the major evolutionary force for the diversification of Micromeria. We also discuss the possible role of gene flow between lineages of different Micromeria species on one island after multiple colonizations.
