Some examples of simple leaves include the sassafras, the white mulberry, the red mulberry and the paper mulberry. A leaf is simple if it has an undivided blade as opposed to the divided blade of a compound leaf. Simple leaves may be lobed, either balanced or unbalanced, or not lobed.
The sassafras, white, red and paper mulberry all have unbalanced lobes. The edges of the sassafras leaf are smooth while the mulberry leaves are toothed. In simple leaves, the gaps between the lobes do not reach the vein while in the compound leaf, each leaflet is separated along the main or secondary vein.
