When the incision of plate reaches up to the vein and breaking it into the variety of leaflets, it's known as compound leaves. 

In a pinnately compound leaves, variety of leaflets area unit gift on a typical axis known as Rashid. 

Example- tree. 

In palmate compound leaves, the leaflets' are hooked up at a typical purpose. 

Example- kapok.
