Abstract: The plants of Sect. Hilliella O. E. Schulz of Cochlearia L. in China are very different from Cochlearia L. s. str., Glaucocochlearia (O. E. Schulz) Pobed. and Pseudosempervivum (Boiss.) Grossh. not only in the habit also in other characters especially in the more or less pustules of the fruits. We think these divergences appear sufficient,foundation fro a genus,and set up this section as a distinct new genus, namely Hilliella (O. E. Sch- ulz) Y. H. Zhang et H. W. Li, and do 8 new combinations for these plants,besides, 3 varieties are new.

Key words: Hilliella
