Arrangement of Leaves on Stem

Arrangement of leaves on a stem is called as Phyllotaxy. There are several methods that plants use to arrange leaves on their stem. It is basically 4 ways as,


In this arrangement, leaves are arranged alternatively on the stem with one leaf per node in a straight line.

Here, two leaves arise from a single node in opposite fashion.

An example for opposite leaves


Only one leaf is present per node as in alternate arrangement. But, the leaves are arranged as a spiral which would be visible if you look down at the apex of the stem.

Multiple leaves arise from a single node and each nodes are separated by huge internodes.

Other arrangements include Subopposite and Deccusate.


Here, the leaves are arranged in such a fashion that they are neither spaced far enough to be considered as alternate nor exactly opposite enough to consider as opposite.

Look carefully and closely at the leaflets. They are neither opposite nor alternate!


This is where two leaves arise from a same node (opposite) in each nodes. The pairs are placed in right angles to each other.
