Monoadelphous stamens are found in :-

Options

A. Lily
B. Brinjal
C. Pea
D. China rose

Answer

To determine which plant has monoadelphous stamens, we need to analyze the characteristics of this type of stamen and evaluate the given options. Here’s a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Understand Monoadelphous Stamens**:
- Monoadelphous stamens are characterized by all the filaments being united into a single bundle, while the anthers remain free. This arrangement forms a tube-like structure.

2. **Evaluate the Options**:
- **Option 1: Lily**: In lilies, the stamens are attached to the perianth (the outer parts of the flower) and are not united into a single bundle. Therefore, lilies do not have monoadelphous stamens.
- **Option 2: Brinjal**: In brinjal, the stamens are arranged to the petals (epipetalous condition) and are not united into a single bundle. Thus, brinjal also does not have monoadelphous stamens.
- **Option 3: Pea**: Pea plants have a diadelphous condition where the stamens are united into two bundles, not one. Hence, pea does not qualify as having monoadelphous stamens.
- **Option 4: China Rose**: In China Rose (Hibiscus), all the stamens are united into a single bundle, which is characteristic of monoadelphous stamens. This is the correct option.

3. **Conclusion**: The plant that has monoadelphous stamens is **China Rose**.

### Final Answer:
Monoadelphous stamens are found in **China Rose**.
