Leaves can be divided into two types:

• Simple leaf
• Compound leaf

SIMPLE LEAF

• In a Simple Leaf, either the incisions are absent or if present, then do not reach the midrib.
• Axillary bud is present at the axil of petiole.

COMPOUND LEAF

• In a Compound Leaf, the incisions reaches the midrib and the lamina is divided into a number of leaflets.
• Axillary bud is present at the axil of petiole but absent at the axil of leaflets.
• Compound leaf are divided into two types on the basis of arrangement of leaflets:

PINNATELY COMPOUND
Number of leaflets are present on a common axis called Rachis which represents the midrib of the leaf.

PALMATELY COMPOUND
 The leaflets are attached at a common point i.e. at the tip of the petiole.
