1. The property of having radial symmetry, especially in flowers or other organisms that can be divided into similar halves by multiple planes passing through the center.
Usage: botanical and biological term; also called radial symmetry

Examples

• The actinomorphy of a daisy flower allows it to be divided into matching sections from multiple angles.
• Starfish display actinomorphy, with arms radiating equally from a central point.
• Botanists study actinomorphy to classify flowering plants into different families.
• The actinomorphy of sea anemones makes them appear symmetrical from above.
• Unlike zygomorphic flowers, those with actinomorphy have no distinct front or back.
