Description	Background and Aims: Nuclear DNA amounts of 12 diploid and one tetraploid taxa and 12 natural interspecific hybrids of Cirsium from 102 populations in the Czech Republic, Austria, Slovakia and Hungary were estimated. Methods: DAPI and PI flow cytometry were used. Key Results: 2C-values of diploid (2n = 34) species varied from 214 pg in C. heterophyllum to 360 pg in C. eriophorum (168-fold difference); the 2C value for the tetraploid C. vulgare was estimated at 554 pg. The DNA contents of hybrids were located between the values of their putative parents, although usually closer to the species with the smaller genome. Biennial species of Cirsium possessed larger nuclear DNA amounts than their perennial relatives. Genome size was negatively correlated with Ellenberg's indicator values for continentality and moisture and with eastern limits of distribution. A negative relationship was also detected between the genome size and the tendency to form natural interspecific hybrids.
