Abstract: The present paper deals with 3 genera,Pugionium Gaertn., Lepidium L. and Torularia O. E. Schulz of the family Cruciferae found in the desert regions of China. Of the genus Pugionium 4 species and 1 new variety and their geographical distribution are recognized. Two closely related species of Lepidium, L. apetalum Willd. and L. ruderale L. and one additional new species are described and their distribution patterns are discussed. Two species of the genus Torularia previously described by V. Botschantzev (1959)are here redused to varietal ranks, and one additional new species is described.
