Answer

To solve the question "Select an incorrect match," we need to analyze the given examples of different types of estivation and determine if they are correctly matched with the respective plants.

### Step-by-Step Solution:

1. **Understand Estivation Types**:
- Estivation refers to the arrangement of petals in a flower bud before it opens. There are several types of estivation, including valvate, twisted, imbricate, and vexillary.

2. **Evaluate the First Match**:
- **Valvate Estivation**: The example given is Callotropis.
- **Analysis**: This is correct. Callotropis exhibits valvate estivation.

3. **Evaluate the Second Match**:
- **Twisted Estivation**: The examples provided are China Rose, Lady's Finger, and Cotton.
- **Analysis**: This is also correct. All three plants exhibit twisted estivation.

4. **Evaluate the Third Match**:
- **Imbricate Estivation**: The example given is Gulmohur.
- **Analysis**: This is correct as Gulmohur does show imbricate estivation.

5. **Evaluate the Fourth Match**:
- **Vexillary Estivation**: The examples provided are Pea, Bean, and Cassia.
- **Analysis**: Pea and Bean do exhibit vexillary estivation, but Cassia does not; it shows imbricate estivation instead.

6. **Identify the Incorrect Match**:
- Since Cassia is incorrectly matched with vexillary estivation, the fourth option is the incorrect match.

7. **Conclusion**:
- The incorrect match is option number 4, which states that Cassia has vexillary estivation.

### Final Answer:
The incorrect match is option number 4: Cassia does not have vexillary estivation; it has imbricate estivation.
