Several closely related plants have been described from the U.S.S.R. but do not appear to warrant specific status, e.g. T. uralense (Krasch.) Tzvelev , op. cit. 346 (1961), from S.E. Russia and S. Ural, said to differ in its oblique rhizome and its more dissected leaves with a broader lamina, T. sclerophyllum (Krasch.) Tzvelev , op. cit. 347 (1961), from the middle Volga basin, with rigid leaves and 2-4(-6) capitula, and T. odessanum (Klokov) Tzvelev , op. cit. 348 (1961), from S. Ukraine and Moldavia, with shorter peduncles and larger capitula.
