Aestivation found in pea flowers is

Options

A. Vexillary
B. imbricate
C. Twisted
D. Valvate

Answer

To determine the type of aestivation found in pea flowers, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Aestivation**: Aestivation refers to the arrangement of petals in a flower bud before it opens. Different types of aestivation include valvate, twisted, imbricate, and vexillary.

2. **Identifying the Structure of Pea Flowers**: Pea flowers (Pisum sativum) have a specific arrangement of their petals. They typically have five petals.

3. **Analyzing the Petal Arrangement**:
- The largest petal is known as the **standard** petal.
- There are two **wing** petals that are lateral to the standard petal.
- The two smallest petals are called the **keel** petals, which are located at the front of the flower.

4. **Describing the Overlap**:
- In pea flowers, the standard petal overlaps the two wing petals.
- The wing petals, in turn, overlap the keel petals.

5. **Classifying the Aestivation Type**: This specific arrangement, where the standard petal is the largest and overlaps the wings, which then overlap the keel, is classified as **vexillary** or **papillonaceous** aestivation.

6. **Conclusion**: Therefore, the type of aestivation found in pea flowers is **vexillary**.

### Final Answer:
The aestivation found in pea flowers is **vexillary**.
