Choose the incorrect match

Options

A. Axile placentation - China rose
B. Free central placentation - Dianthus
C. Polyadelphous stamens - Citrus
D. Tetradynamous condition of staments - Pea

Answer

To solve the question "Choose the incorrect match," we need to analyze each option provided and determine whether the matches are correct or incorrect based on our knowledge of plant biology, specifically placentation and stamen arrangements.

### Step-by-Step Solution:

1. **Understand the Types of Placenta and Stamen Arrangements**:
- We need to identify the types of placentation and stamen arrangements mentioned in the options.

2. **Evaluate Each Match**:
- **Option A: Axile placentation in China Rose**:
- Axile placentation refers to the arrangement where the ovary is divided into locules with ovules attached to the central axis. This is indeed found in China Rose (Hibiscus rosa-sinensis).
- **Conclusion**: This match is correct.

- **Option B: Free central placentation in Dianthus**:
- Free central placentation occurs in a single-chambered ovary with ovules attached to the central axis. This is characteristic of Dianthus (carnation).
- **Conclusion**: This match is correct.

- **Option C: Polyadelphous condition in Citrus**:
- Polyadelphous refers to stamens that are grouped in bundles. This condition is indeed found in Citrus plants (like orange and lemon).
- **Conclusion**: This match is correct.

- **Option D: Tetradynamous condition of stamen in Pea**:
- Tetradynamous refers to a condition where there are six stamens arranged in two whorls, with four being longer and two shorter. This condition is typically found in the family Cruciferae (mustard family) and is not found in Pea (Pisum sativum).
- **Conclusion**: This match is incorrect.

3. **Identify the Incorrect Match**:
- Based on the evaluations, the incorrect match is **Option D**: Tetradynamous condition of stamen is not found in Pea.

### Final Answer:
The incorrect match is **Option D**.
