Answer

To answer the question "If the stamens can swing freely on the filament, the condition is called," we need to analyze the options provided and understand the terms related to the attachment of stamens to the filament.

### Step-by-Step Solution:

1. **Understanding the Question**: The question is asking about a specific condition where the stamens are able to swing freely on the filament.

2. **Evaluating the Options**:
- **Basic Fixed**: In this condition, the filament is attached at the base of the anther, making it fixed. This means the anther cannot swing freely. Therefore, this option is incorrect.

- **Dorsi-Fixed**: In this condition, the filament is attached to the back of the anther. Similar to the basic fixed condition, this also restricts the movement of the anther. Thus, this option is also incorrect.

- **Versatile**: In the versatile condition, the filament is attached to the connective, allowing the anther to swing freely. This means that the anther can move around, which fits the description given in the question. Therefore, this option is correct.

- **Adenate**: In the adenate condition, the filament and the connective appear continuous throughout the length of the anther. This means there is no free movement of the anther, making this option incorrect.

3. **Conclusion**: The correct answer to the question is "Versatile," as it describes the condition where the stamens can swing freely on the filament.

### Final Answer:
The condition where the stamens can swing freely on the filament is called **Versatile**.
