Eight groups differing in ploidy level and/or genome size were discovered, one diploid (2x, 2n = 14), two tetraploid (4xA, 4xB, 2n = 28), one pentaploid (5x, 2n = 35), three hexaploid (6xA, 6xB, 6xC, 2n = 42), and one heptaploid (7x, 2n = 49). The hexaploids (mostly the 6xC cytotype) were widespread through the study area, spreading intensively in both anthropogenic and natural habitats and probably hybridizing with the natural habitat dwelling tetraploids. In contrast, the non-hexaploid cytotypes rarely spread and were predominantly confined to natural habitats.
