The micromorphology of seed coats of 19 species belonging to 12 genera in Cruciferae was studied in this paper. The results showed that the ornamentation of seed coats is of rich diversification with non-conservation characters in comparison with pollen morphology, which is of important value in the study of the taxa under family ranks. The ornamentation of seed coats can be divided into four kinds of patterns including reticulum, diploreticulum, papilla-reticulum, and shepherdspure. Of which the former three kinds can be divided into many sub-patterns. Also, there is a certain connection between the patterns of ornamentation of seed coats and chemical componeets to some extent.
