We resolved taxonomy of the <em>C. maritima </em>group in the Balkans (including the description of a new species), and revised interpretation and circumscription of Eastern Asian species (<em>C. fallax, C. torrentis, C. yezoensis, C. schinziana</em>). We also studied evolutionary processes associated with hybridization and polyploidzation. We confirmed extensive gene flow between <em>C. pratensis</em> and <em>C. raphanifolia</em> in Spain, and underlined the complexity and evolutionary potential of hybrid swarms. High polyploidy and cytotype variation were found in Eastern Asian <em>C. torrentis, C. yezoensis </em> and <em>C. schinziana</em>. Attention has also been devoted to diploid speciation, and the impact of Pleistocene climatic oscillations on genetic variation patterns. We got insights into the evolution of the phylogenetically basal diploid complex of <em>C. maritima</em>, and inferred phylogeographic scenaria of two alpine species, <em>C. resedifolia </em>and <em>C. alpina</em>. </p> </blockquote> </BODY> </HTML>
