| Abstract: | The present paper conducts the comparative observation on leaf venational morphology of 3genus and 5 species in Calycanthaceae. The result shows that 1st veins are moderately stout,2nd veins are much more, 1st veins conshtute brochido-camptodromous or reticulo-camptodromous pinnatoides with 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. |
