The distribution of tetra- and hexaploids was partially sympatric (in the eastern part) to parapatric (in the western part of the Czech Republic) whereas pentaploids were sympatric with other cytotypes. Plants of different ploidy levels were found to be ecologically differentiated and the ruderal character of cytotypes increased in the direction 4x-5x-6x with the largest realized niche differences between tetra- and hexaploids. Most populations contained only one ploidy level (77 %), 22% had two (all possible combinations) and 1% were composed of three ploidy levels.
