Of the main cytotypes, the penta- and tetraploids had strongly overlapping distributions, though the pentaploids exhibited a tendency to occur more frequently in the southern part of Slovakia, while the tetraploids had a tendency to occur in the northern regions. A triploid cytotype was found in one population in the southern part of Slovakia that represents just the third locality worldwide. The hexaploid cytotype was rare, it was found in four populations in two disjunct areas. Fourteen per cent of the sampled populations consisted of more than one ploidy level; the most common was a combination of penta- and tetraploids. The cytotypes differed with respect to altitude; the tetraploids were found significantly more frequently in higher altitudes than the penta- and hexaploids.
