A simple leaf is a leaf, such as an aspen leaf, that does not divide into parts.

A compound leaf is a leaf, such as a walnut leaf, that has several leaflets coming off of a single petiole.

A pinnately compound leaf has leaflets arranged on either side of the central leaf axis, resembling a feather, while a palmately compound leaf has leaflets attached to a single point at the tip of the petiole, resembling an open palm.

In pinnate leaf the leaf lamina forms the leaflets whereas in palmate leaf the lamina becomes palm like.
