What we say if a flower has many pistils.

Answer

To answer the question "What do we say if a flower has many pistils?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Pistil**: The pistil is the female reproductive structure of a flower, which is also referred to as the carpel. It is a crucial part of the flower's gynoecium.

2. **Identifying Types Based on Number of Carpels**: Flowers can have different numbers of carpels, which can be classified as:
- **Monocarpellary**: A flower with a single carpel.
- **Bicarpellary**: A flower with two carpels.
- **Tricarpillary**: A flower with three carpels.
- **Tetracarpillary**: A flower with four carpels.
- **Pentacarpillary**: A flower with five carpels.

3. **Defining Many Pistils**: When a flower has many pistils and we cannot specify an exact number, we refer to this condition as **multicarpellary**.

4. **Example of Multicarpellary Flower**: An example of a flower that exhibits a multicarpellary condition is the Anona (commonly known as custard apple).

5. **Final Answer**: Therefore, if a flower has many pistils, we say it is **multicarpellary**.
