The author reports that the karyotype formula of Bidens bipinnata is K (2n) = 3X = 36 = 27m + 3sm + 6sm (SAT), which belongs to "2A", and that the chromosome composition based on relative length is 2n = 36 = 6L + 9M2 + 18M1 + 3S. The chromosome volume of B. bipinnata is also calculated.
作者报道，鬼针草的核型公式为K(2n)=3X = 36 = 27m + 3sm + 6sm(SAT)，属于“2A”类型，基于相对长度的染色体组成为2n = 36 = 6L + 9M2 + 18M1 + 3S。还计算了鬼针草的染色体体积。
