The term 'polyadelphous' is related to

Options

A. gynoecium
B. androecium
C. corolla
D. calyx

Answer

### Step-by-Step Solution:

1. **Understanding the Term 'Polyadelphous':**
- The term 'polyadelphous' refers to a specific condition found in the androsium of flowering plants. The androsium is the male reproductive part of a flower, consisting of stamens.

2. **Fusion of Filaments:**
- In polyadelphous flowers, the filaments of the stamens are fused together to form several bundles. However, the anthers of these stamens remain separate. This means that while the base of the stamens is united, the pollen-producing parts (anthers) are distinct.

3. **Examples of Polyadelphous Flowers:**
- A common example of flowers exhibiting this condition is found in the citrus family (Rutaceae). In these flowers, you can observe the characteristic grouping of stamens.

4. **Differentiating from Other Floral Parts:**
- It is important to distinguish polyadelphous from other terms related to floral morphology:
- **Gynosium** refers to the female reproductive part of the flower, which includes the ovary, style, and stigma.
- **Corolla** refers to the collective petals of a flower.
- **Calyx** refers to the collective sepals of a flower.

5. **Conclusion:**
- Therefore, the correct answer to the question is that the term 'polyadelphous' is related to the androsium (the male reproductive part) of flowering plants.
