Scutellaria is one of the largest genera in Lamiaceae with an estimated 400–500 species a nearly worldwide distribution. Most occur N hemisphere, Caucasus and wider Irano-Turanian region housing large number taxa, many them considered endemic. We present overall phylogeny monophyletic genus based on rapidly evolving plastid regions (matK-trnK, rpl16, trnL-F). Three well-supported clades are evi...

The West-Palearctic region is a diversity hotspot for the ant genus Aphaenogaster . Species in this are characterized by high morphological variation, which has led to their subdivisioninto different infrageneric groups. very first classification three subgenera, dated 1915, was gradually replaced eight species-groups. To probe evolutionary consistency of these species-groups, we sequenced 46 s...

BACKGROUND AND AIMS Rheum, a highly diversified genus with about 60 species, is mainly confined to the mountainous and desert regions of the Qinghai-Tibetan plateau and adjacent areas. This genus represents a good example of the extensive diversification of the temperate genera in the Qinghai-Tibetan plateau, in which the forces to drive diversification remain unknown. To date, the infrageneric...

We performed a phylogenetic analysis of the fern genus Elaphoglossum using two non-coding chloroplast spacers: trnL-trnF and rps4-trnS. The sampling includes 123 species, of which 80 have not been previously sequenced, and for the first time includes species from Africa and the Indian Ocean area. The results of this expanded study largely agree with an earlier molecular study based on a smaller...

BACKGROUND AND AIMS The genus Rosa (150-200 species) is widely distributed throughout temperate and sub-tropical habitats from the northern hemisphere to tropical Asia, with only one tropical African species. In order to better understand the evolution of roses, this study examines infrageneric relationships with respect to conventional taxonomy, considers the extent of allopolyploidization and...

PREMISE OF THE STUDY Palaeotropic Derris-like taxa (family Fabaceae, tribe Millettieae) comprise 6-9 genera. They are well known as important sources of rotenone toxin, which are used as organic insecticide and fish poison. However, their phylogenetic relationships and classification are still problematic due to insufficient sampling and high morphological variability. METHODS Fifty species o...
