Answer

To solve the question of selecting the incorrect combination, we will analyze each option provided in the question step by step.

### Step 1: Analyze the First Option
- **Epiphyllous Stamen in Lily Family**:
- Definition: Epiphyllous stamen means that the stamens are attached to the petals.

**Conclusion**: This option is correct.

### Step 2: Analyze the Second Option
- **Polyandrous Condition in China Rose**:
- Definition: Polyandrous means that there are multiple stamens that are fused together.
- Verification: In the case of China rose (Hibiscus rosa-sinensis), the condition is actually epipetallous, meaning the stamens are attached to the petals but are not fused.

**Conclusion**: This option is incorrect.

### Step 3: Analyze the Third Option
- **Diadelphous Stamen in P (Pea Plant)**:
- Definition: Diadelphous means that the stamens are in two groups.

### Step 4: Analyze the Fourth Option
- **Polydelphous Stamen in Citrus**:
- Definition: Polydelphous means that the stamens are in more than two groups.
- Verification: This condition is indeed found in citrus plants.

**Conclusion**: This option is correct.

### Final Conclusion
After analyzing all the options, we find that:
- The first option (epiphyllous stamen in lily) is correct.
- The second option (polyandrous condition in China rose) is incorrect.
- The third option (diadelphous stamen in pea) is correct.
- The fourth option (polydelphous stamen in citrus) is correct.

Thus, the incorrect combination is the second option regarding the polyandrous condition in China rose.
