Types of leaf phyllotaxy:

The arrangement of leaves on the stem is called phyllotaxy.

1) Alternate:

When only one leaf develops at each node, e.g., Brassica campestris, Nicotiana tabacum.

2) Decussate and opposite:

When two successive pairs of leaves occur at right angle to each other, e.g., Psidium.

3) Cluster (Whorled):

When more than two leaves are arranged in the form of a whorl at each node the phyllotaxy is called whorled, e.g., Hydrilla verticillata, Nerium, etc.

4) Verticillate (Spiral)

Leaves grow one by one, each at a constant divergence angle d from the previous one.
