Among the offspring of a problematic form of Achillea sp., a 2n = 126 seedling which probably arose as the result of fusion of unreduced octo- and hexaploid gametes (72 + 54) was found along with seedlings having an octaploid chromosome number (2n = 72). Putative paths leading to the formation of problematic octaploid forms and plants with 126 chromosomes are discussed
