	abstract = {The relationships of Vitex and genera historically placed in Lamiaceae subfamily Viticoideae were investigated. Particular focus was given to some South East Asian genera traditionally allied to Vitex (Paravitex, Tsoongia, Viticigremna, Tejismanniodendron) since progress with South East Asian Floras is being hampered by a lack of clarity in current generic delimitation. On the basis of maximum parsimony and Bayesian phylogenetic analyses of ITS and ndhF sequence data we provide evidence that the Viticoideae is not monophyletic, its members being spread between a number of clades which include genera currently recognised as incertae sedis (Peronema, Hymenopyramis, Petraeovitex, Tectona). The most well Supported clade, the Vitex group, contains Vitex, Paravitex, Tsoongia, Viticipremna, Petitia and Teijsmanniodendron. Morphological similarities of the genera included in this group are also discussed. In light of this evidence Paravitex, Viticipremna and Tsoongia are reduced to synonymy with Vitex, the new combinations being made here. The position of Teijsmanniodendron is not resolved and its generic status is therefore upheld. Similarly, PC-litia is upheld due to a lack of neotropical taxa within the sample.},

	abstract = {Dicerandra, an endemic mint of the southeastern United States, comprises nine species, all of which are threatened or endangered and restricted to sandhill vegetation and a mosaic of scrub habitats. Molecular phylogenetic analyses of Dicerandra based on data from the nuclear and plastid genomes for all 13 taxa of the genus, identified two strongly supported clades, corresponding to the four annual and to the five perennial species of Dicerandra. However, the nuclear and plastid trees were incongruent in their placement of two perennial taxa, D. cornutissima and D. immaculata var. savannarum, perhaps due to ancient hybridization or to lineage sorting. Based on these analyses, the widespread D. linearifolia is not monophyletic, with populations of D. linearifolia var. linearifolia falling into either western or eastern clades. The western clade, comprising populations of D. linearifolia var. linearifolia and var. robustior, occurs in an area drained by rivers flowing toward the Gulf of Mexico, whereas the eastern clade, comprising populations of D. linearifolia var. linearifolia, D. densiflora, D. odoratissima, and D. radfordiana (i.e., all the annual species), occupies a region drained by rivers flowing to the Atlantic Ocean. Although this pattern of genetic differentiation between populations from these two river drainages has been documented in several animal species, it has not previously been reported for plants. A revised subgeneric classification is presented to reflect the annual and perennial clades.},

	abstract = {Conradina (Lamiaceae) consists of six allopatric species endemic to the southeastern United States, four of which are federally endangered or threatened. The limits and status of several taxa have been contested based on morphological grounds, and clarification of these limits is necessary for the design and implementation of effective and fiscally responsible protection and management plans. The objectives of this study were to investigate the monophyly of Conradina and its relationship to other endemic mints of the southeastern United States, to understand the patterns of diversification in Conradina, and to clarify species relationships. A molecular phylogeny was inferred by sequencing ITS and plastid regions from multiple accessions of each species of Conradina (except for a single accession of C. verticillata) and multiple individuals from species of Clinopodium, Dicerandra, Piloblephis, Stachydeoma, Monarda, Pycnanthemum, and Mentha. ITS sequence data strongly support the monophyly of Conradina, in agreement with evidence from morphology. In contrast, plastid sequence data do not support a monophyletic Conradina and place the genus as paraphyletic to Clinopodium, Stachydeoma, and Piloblephis. Similar plastid haplotypes are shared by different genera, perhaps due to shared ancestral polymorphisms, or more likely, introgression that occurred recently or during the Pleistocene. Within Conradina, ITS sequence data do not resolve species relationships, while plastid sequence data do not support the monophyly of most traditionally defined species of Conradina that are distinguishable morphologically. Species relationships in the plastid data set may also be obscured by introgression or ancestral polymorphism. More rapidly evolving sequence data from nuclear markers will be necessary to clarify relationships in Conradina and related mints from the southeastern United States.},

	abstract = {Calyces of 306 species representing 181 out of the 236 genera of Lamiaceae have been studied with particular emphasis on the amount of fibres and similar xylem cells. A characteristic calyx tissue called "mesophyll fibres", reported by earlier authors, is found to belong to the xylem. Most species of the subfamilies Lamioideae and Scutellarioideae differ from most other labiates, and particularly from Nepetoideae, in having much larger amounts of fibres and similar xylem cells in the calyx tube. This result supports cladistic hypotheses based on cpDNA showing that Lamioideae and Scutellarioideae are closely related and remotely related to Nepetoideae. The new data also contribute to the knowledge about the phylogeny within Lamioideae. The amount of fibres and similar cells also seems to be positively correlated with calyx size, calyx width, a ballistic dispersal mechanism in Scutellaria, and the aridity of the habitat. Possible adaptive significances of these correlations are discussed.},

	abstract = {Background and Aims The genus Salvia has traditionally included any member of the tribe Mentheae (Lamiaceae) with only two stamens and with each stamen expressing an elongate connective. The recent demonstration of the non-monophyly of the genus presents interesting implications for staminal evolution in the tribe Mentheae. In the context of a molecular phylogeny, the staminal morphology of the various lineages of Salvia and related genera is characterized and an evolutionary interpretation of staminal variation within the tribe Mentheae is presented.Methods Two molecular analyses are presented in order to investigate phylogenetic relationships in the tribe Mentheae and the genus Salvia. The first presents a tribal survey of the Mentheae and the second concentrates on Salvia and related genera. Schematic sketches are presented for the staminal morphology of each major lineage of Salvia and related genera.Key Results These analyses suggest an independent origin of the staminal elongate connective on at least three different occasions within the tribe Mentheae, each time with a distinct morphology. Each independent origin of the lever mechanism shows a similar progression of staminal change from slight elongation of the connective tissue separating two fertile thecae to abortion of the posterior thecae and fusion of adjacent posterior thecae. A monophyletic lineage within the Mentheae is characterized consisting of the genera Lepechinia, Melissa, Salvia, Dorystaechas, Meriandra, Zhumeria, Perovskia and Rosmarinus.Conclusions Based on these results the following are characterized: (1) the independent origin of the staminal lever mechanism on at least three different occasions in Salvia, (2) that Salvia is clearly polyphyletic, with five other genera intercalated within it, and (3) staminal evolution has proceeded in different ways in each of the three lineages of Salvia but has resulted in remarkably similar staminal morphologies.},

	abstract = {The genus Cyclotrichium, a member of the tribe Mentheae subtribe Menthinae (Lamiaceae, Nepetoideae), was analysed with respect to morphological revision, phylogenetic analysis, and cytogenetic properties. All species of the genus were investigated for morphological characters and ITS (internal transcribed spacers) of nrDNA sequence comparison (except C. hausknechtii for ITS). Six members of the genus were also analysed for chromosome numbers. The combined results strongly suggested that Cyclotrichium is a separate genus in Nepetoideae with distinct morphological, phylogenetic, and cytogenetic characteristics. For intrageneric phylogeny of Cyclotrichium, 3 groups were recognised: 1. C. niveum; 2. C. origanifolium; and 3. the remaining 6 species. Clinopodium s.l. and Mentha appear to be most closely related to Cyclotrichium. The phylogenetic relationship of Cyclotrichium with Clinopodium s.l., Mentha, Micromeria, Melissa, and Satureja is discussed. This is the first report on the somatic chromosome numbers of 6 Cyclotrichium species and phylogenetic analysis of Cyclotrichium based on (nrDNA) ITS sequences.},
