Answer

To solve the question "Select an incorrect statement with respect to flower," we will analyze each statement provided.

### Step-by-Step Solution:

1. **Understand the Types of Flowers**:
- The first statement discusses trimeris, tetrameris, and pentameris flowers. These terms refer to flowers with floral parts in multiples of 3, 4, and 5, respectively.
- **Conclusion**: This statement is correct.

2. **Examine the Definition of Bracts**:
- The second statement claims that "bracts are reduced leaves found at the base of the receptacle."
- Bracts are indeed modified leaves, but they are not necessarily reduced leaves. They can serve various functions, including protection of the flower or attracting pollinators.
- **Conclusion**: This statement is incorrect.

3. **Zygomorphic Flowers**:
- The third statement states that "zygomorphic flower has bilateral symmetry."
- Zygomorphic flowers can be divided into two equal halves along one plane, which is a characteristic of bilateral symmetry.
- **Conclusion**: This statement is correct.

4. **Asymmetric Flowers**:

- Asymmetric flowers, which cannot be divided into two equal halves, are indeed referred to as irregular flowers.
