What shape are the leaves of Ginkgo biloba?

The leaves of Ginkgo biloba are characteristically fan-shaped, featuring a leaf stalk (petiole) and a blade, or lamina, with dichotomous venation.1

While the name biloba refers to the two-lobed form often seen on these leaves, there is significant variation in their shape. Leaves can be undivided, bilobed, or even multilobed, depending on their location on the tree. For instance, most leaves found on the upper parts of long branches are divided by a deep sinus into two lobes, while leaves on short, or spur, branches may be either bilobed or undivided.1
