Abstract: The present paper conducts the comparative observation on leaf venational morphology of 8 species and 1 variety in Lepidium. The result shows that 1st veins have mederate stout, 1st basal veins in basis 1- 2 doublet constitute campto-brochidodromous pinnatoides with the 2nd veins; 3rd veins are percurrent or reticulate, at the margin, veinlets are incomplete areole has not a norm in shape and area, it is imperfect in system development. This paper provides the additional evidence for evolution of Cruciferae.
