Aucklandia and Frolovia are very closely related. In a molecular study by Y. J. Wang et al. (Ann. Bot. 99: 311-322. 2007), the two genera form together a small clade, which is nested within the morphologically much different genus Dolomiaea. However, as sampling and analysis of this group is not yet complete, we prefer not to make generic rearrangements of these species here. In C. Shih and S. Y. Jin (FRPS 78(2): 58. 1999), the species of this genus is included in Saussurea subg. Frolovia.
