The text seems to be cut off, but based on the information given, it appears to be describing a characteristic of flower symmetry. When a flower can be divided into two equal halves in any radial plane passing through the center, it is said to be radially symmetrical or actinomorphic. This is a common characteristic of many flowers, such as roses and daisies. Here are the steps to identify this:

1. Look at the flower from the top view.
2. Imagine or draw lines that pass through the center of the flower.
3. If each line divides the flower into two equal halves, then the flower is radially symmetrical or actinomorphic.
4. If not, then the flower is not radially symmetrical. It might be bilaterally symmetrical (can be divided into two equal halves in one specific plane) or asymmetrical (cannot be divided into two equal halves by any plane).
