SYMMETRY OF FLOWER
1. Actinomorphic/ Radial/ Regular
When a flower can be divided into two equal radial halves by any vertical plane or radial plane passing through the center.
Example- Chilli, Datura, Mustard
2. Zygomorphic/ Bilateral
When a flower can be divided into two equal (similar) halves only by one particular plane.
Example- Bean, Pea, Cassia
3. Asymmetrical/ Irregular
When a flower can not be divided into two equal halves from any vertical plane passing through the center.
Example - Canna
