Field observations and collections were made from the only known population. Although the A. ageratoides complex has been cytologically studied for a long time and clearly shows complex patterns of polyploidy (Huziwara, 1957; Matsuda & Suyama, 1980; Yoshida et al., 1986; Chen et al., 1992; Soejima, 1992; Ito et al., 1994; Ito & Soejima, 1995; Soejima & Peng, 1998; Soejima et al., 1999, 2005; Li, 2002, 2004, 2005, 2006; Li & Liu, 2005a, b), the chromosome number variation of var.
