corymb has

Options

A. long peduncle
B. shorter peduncle
C. no peducle
D. flattened peduncle

Answer

### Step-by-Step Solution:

1. **Understanding Corymb**: Corymb is a type of inflorescence where flowers are arranged on a common axis.

2. **Characteristics of Corymb**: In a corymb, the peduncle (the main flower stalk) is relatively short. This allows the lower flowers to have longer pedicels (the stalks that attach individual flowers to the main stem) so that all the flowers can be positioned at approximately the same height.

3. **Comparison with Other Types**:
- **Long Peduncle**: This would mean that the flowers would not be at the same level, which is not characteristic of a corymb.
- **No Peduncle**: This is not applicable as a peduncle is essential for any type of inflorescence.
- **Flattened Peduncle**: This term does not accurately describe the structure of a corymb.

4. **Conclusion**: Given the characteristics of a corymb, the correct answer is that it has a **shorter peduncle**.

### Final Answer:
Corymb has a **shorter peduncle**.
