A single plant of Saussurea ussuriensis from Liaoning has been described as S. ussuriensis var. laxiodontolepis. The description matches the typical variety of S. ussuriensis, except for the dentate phyllaries, which may be the result of introgression from S. odontolepis or S. pectinata. Also, Lipschitz (Fl. URSS 27: 448. 1962) reported hybrids of S. ussuriensis with S. odontolepis.
