Abstract: Almost no differences are seen in habit and infrescence between the genera Vladimiria and Dolomiaea; the former that was founded on the basis of Jurinea salwinensis Hand.-Mazz. by Iljin should be transferred to the later that was earlier founded on the basis of D. macrocephala DC. by De Candolle. But considering the style which has fine, spreading and apex-acute branches in the group Vladimiria, it is reasonable to treat the group Vladimiria as a section in the genus Dolomiaea, i.e. Dolomiaea sect. Vladimiria (Iljin) Shih. Therefore, the genus Dolomiaea is expanded in the circumscription in the present paper, not only including the primary group with short, compact and apex-rounded style branches, i.e. Dolomiaea sect. Dolomiaea, but also sect. Vladimiria (Iljin) shih with different characters of style-arms. Nine species and 1 variety as new combinations are listed in the sect. Vladimiria (Iljin) Shih as following: D. denticulata (Ling) Shih, D. forrestii (Diels) Shih, D. scabrida (Shih et S. Y. Jin) Shih, D. souliei(Franch.) Shih, D. souliei (Franch) Shih var. mirabilis (Anth.) Shih, D. berardioidea (Franch.) Shih, D. georgii (Anth.) Shih, D. edulis (Franch.) Shih, D. salwinensis (Hand.-Mazz.) Shih and D. platylepis (Hand. -Mazz.) Shih.
