The aestivation that may be seen in the sepals of family Papilionoideae is

Options

A. vexillary
B. imbricate
C. contorted
D. all of these

Answer

To solve the question regarding the type of aestivation seen in the sepals of the family Papilionoideae, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Family**: The question specifies the family Papilionoideae, which is a subfamily of the Fabaceae family (legumes).

2. **Understand Aestivation**: Aestivation refers to the arrangement of sepals and petals in a flower bud before it opens. Different families exhibit different types of aestivation.

3. **Types of Aestivation**: The common types of aestivation include:
- **Imbricate**: Sepals overlap each other, but not in a regular pattern.
- **Vexillary**: One sepal is larger and covers the others, which are arranged in a specific manner.
- **Contorted**: Sepals overlap each other in a regular manner, often in a spiral.
- **Valvate**: Sepals touch at the edges but do not overlap.

4. **Research Aestivation in Papilionoideae**: In the Papilionoideae subfamily, the most commonly observed type of aestivation is the imbricate type. This means that the sepals are arranged in such a way that they overlap each other irregularly.

5. **Conclusion**: Based on the characteristics of the Papilionoideae family, we conclude that the aestivation seen in the sepals is predominantly **Imbricate**.

### Final Answer:
The aestivation that may be seen in the sepals of family Papilionoideae is **Imbricate**.
