The incision reaching up to the midrib forms
Compound leaf
Simple leaf
Incised leaf
All of these
There are two types of leaves on the basis of the shape of lamina:
1. Simple Leaves: When the lamina of the leaf is entire or when incised, the incision do not touch the midrib, the leaves are called simple leaves. In other words, leaves with undivided lamina are called simple leaves. For example, mango, brassica, etc.
2. Compound Leaves: When the lamina is divided by the incisions such that these incisions reach upto the midrib, breaking it into number of leaflets, the leaves are called compound leaves. The compound leaves can be further divided into pinnately compound and palmately compound leaves. For example, neem and cotton.
The axillary buds arise from the axils of both the simple and compound leaves. No bud arises from the axils of leaflets of compound leaves.
