Phyllotaxy -

Phyllotaxy: The pattern of arrangement of leaves on the branch or stem is called the phyllotaxy. There can be following types of arrangement of leaves:

a) Alternate or Spiral Phyllotaxy: A single leaf arises from each node in an alternate fashion. The arrangement appears to be spiral. For example, China rose, mustard and sunflower.

b) Opposite Phyllotaxy: A pair of leaves arises at each node and lie opposite to each other. For example, Calotropis and guava.

c) Whorled Phyllotaxy: More than two leaves arise at a node and form a whorl. For example, Alstonia, Nerium, etc.
