Explain: Polyadelphous cohesion of stamens.

Answer

### Step-by-Step Solution:

1. **Understanding Cohesion of Stamens**:
- Cohesion of stamens refers to the union of stamens among themselves. This means that the stamens are not separate but are joined together in some form.

2. **Types of Cohesion**:
- There are different types of cohesion of stamens. One important type is known as polyadelphous cohesion.

3. **Definition of Polyadelphous Cohesion**:
- In polyadelphous cohesion, the filaments of the stamens are united in more than two bundles. This means that instead of individual stamens, the filaments come together to form multiple groups or bundles.

4. **Characteristics of Polyadelphous Cohesion**:
- One key characteristic of polyadelphous cohesion is that the anthers remain free. This means that while the filaments are grouped together, the anthers (the part of the stamen that produces pollen) are not attached to each other and can move independently.

5. **Example of Polyadelphous Cohesion**:
- A common example of a plant exhibiting polyadelphous cohesion is Bombax seiba. In this plant, the filaments can be seen united in several bundles, typically four, while the anthers are free.

6. **Visual Representation**:
- A schematic diagram can help illustrate polyadelphous cohesion. In such a diagram, you would see the filaments grouped into more than two bundles, with the anthers clearly shown as separate entities.
