Spach (Labiatae) from Andean South America was long held to be closely related to Macaronesian Bystropogon L'Her. or to North American Pycnanthemum Michx. The possibility of a close relationship to elements of South American Satureja/Clinopodium s.l. is here proposed for the first time, and a phylogenetic analysis of nrITS data is employed to test the competing hypotheses. For Minthostachys and its putative closest relatives, the possible evolution of morphological characters is investigated with a cladistic analysis. The results suggest that Minthostachys is nested in a clade of South American Mentheae, and probably in the former genus Xenopoma Willd., a group of small-flowered, bee-pollinated species currently included in Clinopodium L.. Minthostachys is considered monophyletic based on nrITS data and its scandent habit.10aBootstrap10aBystropogon10aConfidence10aGenus Bystropogon Lamiaceae10aIts10aLabiatae10aLamiaceae10aLimits10aMentheae10aMinthostachys10aMu(N)Over-Tildea10aNuclear Ribosomal Dna10aRegion1 aSchmidt-Lebuhn, A., N  uhttp://www.springerlink.com/content/m572q7rj3u8225h8/04212nas a2200337   4500008004100000245011100041210006900152260000800221300001400229490000700243520296400250653002003214653002603234653003203260653002403292653001403316653001403330653002503344653002703369653002403396653001803420653002603438653002303464653002103487653001303508653002603521100002603547700002103573700002003594856026003614       2010                        eng d00aMolecular phylogeny of Menthinae (Lamiaceae, Nepetoideae, Mentheae) - Taxonomy, biogeography and conflicts0 aMolecular phylogeny of Menthinae Lamiaceae Nepetoideae Mentheae   cJan  a501–5230 v553 aAlthough the subfamily Nepetoideae (Lamiaceae) is considered to be monophyletic, relationships between tribes, subtribes and genera within the subfamily are poorly understood as complex and possibly homoplasious morphological characters make taxa difficult to delimit. 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.

Polium of the genus Teucrium shows both intersectional congruence and intrasectional incongruence with traditional morphological classifications. We attribute this incongruence largely to problems related to the polyploid complex studied. Section Polium includes many poorly differentiated taxa of probable recent origin through hybridization followed by polyploidization. Both on the basis of parsimony and distance (Neighbor-Joining method) analyses, T. dunense and T. thymifolium are the species that diverge most from the sampled taxa. However, unlike T. thymifolium, the morphology of ir: dunense is not much differentiated in relation to the other taxa. Both species are, nonetheless, the only sampled species to occupy isolated, exclusive environments and which may have undergone rapid evolution by a bottleneck effect. Teucrium dunense is found only on dunes along the Spanish and French coasts and ir: thymifolium, a chasmophytic species with limited endemism, is found solely on limestone and dolomite cliffs in the low mountains in south-eastern Spain. A hypothesis is presented to explain the discrepancy between the observed comparatively large amount of ITS sequence divergence and the low morphological differentiation in T. dunense.10aEvolution10aInternal Transcribed Spacer Region (Its)10aLabiatae10aLamiaceae10aNuclear Ribosomal Dna10aNucleotide-Sequences10aPhylogenetic Analysis10aPhylogeny10aPolyploid Complex10aPopulations10aRbcl10aSect.

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.10aArmeria Plumbaginaceae10aChloroplast Dna10aIncongruence10aLength Difference Test10aMaximum-Likelihood10aMitochondrial-Dna10aNoncoding Regions10aNuclear Ribosomal Dna10aReticulate Evolution10aSequences1 aEdwards, CE1 aSoltis, DE1 aSoltis, PS  uhttp://apps.isiknowledge.com/InboundService.do?product=WOS&action=retrieve&SrcApp=Papers&UT=000236119500018&SID=2AFL5dnj5MCc8JPedL5&SrcAuth=mekentosj&mode=FullRecord&customersID=mekentosj&DestFail=http%253A%252F%252Faccess.isiproducts.com%252Fcustom_image02786nas a2200301   4500008004100000245016200041210006900203260000800272300001400280490000700294520158600301653001901887653002001906653002601926653003201952653002601984653002302010653003102033653003102064653001802095653001902113100001502132700001702147700001502164700002102179700002402200856026002224       2004                        eng d00aUsing molecular data to test a biogeographic connection of the Macaronesian genus Bystropogon (Lamiaceae) to the New World: A case of conflicting phylogenies0 aUsing molecular data to test a biogeographic connection of the M  cJan  a702–7150 v293 aBystropogon (Lamiaceae) is endemic to the Macaronesian Islands and represents the best-known example of a putative phytogeographic connection between these islands and the New World. Previous morphological taxonomic studies suggested that this genus is closely related to the western South American Minthostachys. Phylogenetic analyses of nucleotide sequences of the internal transcribed spacers and 5.8S subunit of nuclear ribosomal DNA and the trnL gene and trnL-trnF spacer of the chloroplast genome for 33 of the 72 genera in the Mentheae tribe were performed. Maximum parsimony analysis of the combined data set resulted in 63 most parsimonious trees. The strict consensus tree of this analysis shows with moderate bootstrap support (74%) that Bystropogon is sister to the Old World taxa Acinos, Ziziphora, and Clinopodium vulgare. When analyzed separately, the ITS and trnL/F data sets do not agree as to the sister group to Bystropogon, although none supports a sister relationship with Minthostachys. The cpDNA phylogeny strongly supports a relationship of Bystropogon with a clade of New World mint taxa (90% bootstrap value). Due to the apparent conflict between the chloroplast and nuclear characters observed in the phylogenies, we are not certain of the true biogeographic relationship of Bystropogon. Finally, in all analyses, all of the Mentheae genera sampled in this study form a monophyletic group (100% bootstrap value) and a derived clade of ten New World genera is found. These results contribute to our understanding of generic relationships within the tribe.10aCanary-Islands10aChloroplast Dna10aIlex L.

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.
