In order to be pinnately lobed, a lamina must be incised so that a line connecting the sinuses between the lobes is approximately parallel to the midrib (Figure D); in some Quercus leaves, however, a line connecting the sinuses is parallel to a line connecting the apices of the lamina segments which, therefore, are classified as teeth rather than lobes (Figure E).

In palmately lobed leaves (Figure F), the lobes are entered by a major primary vein that originates at or near the base of the leaf.  

D) Pinnately lobed leaf. Here a line joining the troughs of the sinuses runs roughly parallel to the midvein.		E) When a line connecting the sinuses runs parallel to the leaf margin the lamina segments are classified as teeth.		F) A palmately lobed leaf.

Early in CLAMP development both pinnately and palmately lobed leaves (Figures D and F) were scored separately but were later combined because separate scoring appeared to produce no refinement.
