In this study, a new species, P. nana, from northeast Chongqing in the north of the Yangtze River is described and illustrated. Bayesian inference and maximum likelihood analyses based on two nuclear ribosomal DNA regions (ITS and ETS) and three plastid DNA markers (rpl32-trnL, rps16, and trnL-trnF) were carried out to explore the phylogenetic position of the new species within Paraphlomis.

Gene flow between species, across ploidal levels, and even between evolutionary lineages is a common phenomenon in the genus Arabidopsis. However, apart from two genetically fully stabilized allotetraploid species that have been investigated in detail, the extent and temporal dynamics of hybridization are not well understood. An introgression zone, with tetraploid A. arenosa introgressing into A. lyrata subsp.

Although horizontal gene transfer (HGT) is a widely accepted force in the evolution of prokaryotic genomes, its role in the evolution of eukaryotic genomes remains hotly debated. Some bdelloid rotifers that are resistant to extreme desiccation and radiation undergo a very high level of HGT, whereas in another desiccationresistant invertebrate, the tardigrade, the pattern does not exist.

In the present study the phylogeny and the biogeography of the genus Lilium L. section Liriotypus Asch. et Graebn. were investigated and divergence times for the section Liriotypus were calculated. The study group covers Lilium species from Europe, the Italian and Balkan peninsulas, Anatolia, and the Caucasus.

Phylogenetic relationships among the species of Hellenocarum and its close allies (Umbelliferae-Apioideae) were investigated using nuclear (ITS, ETS) and plastid (psbA-trnH intergenic spacer) DNA sequences. The results obtained were supplemented with an examination of morphology from herbarium and field-collected materials, as well as details of fruit anatomy obtained from light and scanning electron microscopy

These plastid DNA sequence data also demonstrate that the western clade of C. crispa, specifically the western Asian clade, is the maternal progenitor of C. bithynica. Our analysis of DNA sequence data from the biparentally inherited nuclear locus gapCp supports an autopolyploid origin of C. bithynica, with C. crispa as the sole progenitor.

Alopecurus goekyigitiana, a new species from the Taurus Mountains of Turkey, is described and illustrated. Phylogenetic analyses of DNA sequence data support its relationship within Alopecurus sect. Colobachne with A. gerardi (plastid), or with the complex of A. davisii, A. lanatus, and A. vaginatus (nuclear ribosomal spacers).

The evolution and taxonomy of the core members of subtribe Vellinae (Brassicaceae), comprising Vella aspera, V. bourgeana, and V. pseudocytisus, is still poorly known. We reconstructed the evolutionary relationships among these taxa and other Vellinae and close Brassicaceae using nuclear ITS and plastid trnTF phylogenies, and analyzed the phenotypic traits that differentiate the infraspecific ranks of V. pseudocytisus.
