How do you describe a lobed leaf?

How do you describe the shape of a leaf?
Shape of the Leaf
- Cordate: Heart shaped, with a sharp tip at the apex and the petiole coming out between the rounded parts of the heart at the leaf base.
- Elliptical: Longer than wide, but tapers at both ends.
- Lanceolate: Longer than wide, but tapers smaller at the apex.
- Linear: narrow and the same width at both ends.
What is the purpose of lobed leaves?
The light-rich upper leaves (as previously mentioned) tend to be smaller and more lobed than the lower. This leaf shape facilitates heat loss and prevents extreme self-shading.

Leaves are different shapes. This is because they have different margins. There are many types of margins including entire, dentate, serrate, sinuate, lobed and palmate.
What is an example of a leaf margin?
Serrate leaves have a leaf margin that looks similar to a saw or serrated knife. The spacing between the teeth does not need to be even and the “blades” of the margin can point straight or lean to one side or the other. Some examples of trees with serrate leaves include apple trees (Malus domestica), boxelder trees (Acer negundo).
