Leaf architectural features in nine genera and eleven species of the Meliaceae have been studied. The major venation pattern conforms to pinnate camptodromous either with eucamptodromous or brochidodromous and mixed craspedodromous types. The highest degree of vein order is up to 7°. Leaf architectural characteristics such as the presence of major venation categories, nature of the marginal ultimate venation, areoles, presence or absence of bundle sheath and the type of leaf margin are found to be helpful in delimiting the taxa studied. Accordingly, a key is prepared for the identification of the species investigated.
