Palmately compound leaves are a type of compound leaves. Here leaflets are attached at the tip of the petiole.
Leaves are categorised into two main types based on the division in the lamina. Simple leaves are undivided or the incision does not reach the midrib. Compound leaves have their lamina separated into multiple leaflets.
Compound leaves are of two types:
- Pinnately Compound Leaves – Here, leaflets are present on the rachis (common axis), which represents the midrib. E.g. Neem leaf.
- Palmately Compound leaves – Here, leaflets are attached together at one point, i.e. petiole tip. E.g. Silk cotton.
Types of Palmately Compound Leaves
On the basis of the number of leaflets present, palmately compound leaves are of the following types:
- Unifoliate – a single leaflet attached at the tip of the petiole, e.g. lemon
- Bifoliate – a pair of leaflets attached to petiole, e.g. Zornia, Bauhinia, Prinsepia
- Trifoliate – three leaflets are present, e.g. clover, oxalis, Potentilla indica
- Quadrifoliate – four leaflets are present, e.g. Marsilia
- Multifoliate – five or more leaflets are attached to the petiole, e.g. Bombax, Gynandropsis
