a) Unipinnate Compound Leaf: When the leaflets are borne directly on the rachis itself. If the number of leaflets is odd, it is called imparipinnate compound leaf.  If the number of leaflets is even, it is called paripinnate compound leaf. For example, neem
b) Bipinnate Compound Leaf: The primary rachis is branched into secondary rachis and the leaflets are borne on the secondary rachis. For example, Touch-me-not
c) Tripinnate Compound Leaf: The primary rachis is branched twice and the leaflets are borne on the tertiary rachis. For example, drumstick
d) Decompound Compound Leaf: The rachis is branched thrice or more than thrice and the leaflets are borne on the ultimate rachis. For example, coriander.
