Figure: Types of Phyllotaxy
In this form, the leaves are arranged alternatively in the nodes. There is merely one leaf at each node. Example: Polyalthia.Opposite Phyllotaxy:
In this form of arrangement two leaves are existed at each node, lying opposite to one other. It is of two forms:
a) Opposite superposed:
The pairs of leaves arranged in consecutive nodes and are in similar direction that is two opposite leaves at a node lie precisely above those at the lower node Example: Guava
b) Opposite decussate:
In this form of phyllotaxy one pair of leaves are located at right angles to the next upper or lower pair of leaves. Example: CalotropisTernate Phyllotaxy:
In this form there are three leaves joined at each node example: Nerium
In this form, more than three leaves are present in a spiral at each node. Example: Alamanda.
