The leaf in which the leaf lamina is wholly divided into distinct leaflets is known as a compound leaf. The leaf has incisions reaching the midrib. The compound leaves are of two types.
Pinnately compound leaf: In the pinnately compound leaf, the midrib forms a common axis called the rachis. Leaflets are arranged on the rachis in the same plane of the leaf.
Palmately compound leaf: The leaflets are attached to a common origin, at the tip of the petiole.
