Answer

To find the plant with trimerous flowers and polyembryony in seeds, we can follow these steps:

### Step 1: Understand the Terms
- **Trimerous Flowers**: Flowers that have parts in multiples of three, meaning there are three petals and three sepals.
- **Polyembryony**: A condition where more than one embryo is present in a single seed, which can occur when multiple ovules develop into embryos.

### Step 2: Identify Potential Plants
- We need to look for plants that are known for having trimerous flowers and exhibiting polyembryony.

### Step 3: Analyze Different Plants
1. **Citrus**:
- Flowers: Pentamerous (5 petals and 5 sepals).
- Polyembryony: Not observed.
- Conclusion: Does not meet the criteria.

2. **Mangifera (Mango)**:
- Flowers: Pentamerous (5 petals and 5 sepals).
- Polyembryony: Not observed.
- Conclusion: Does not meet the criteria.

3. **Allium (Onion)**:
- Flowers: Trimerous (3 petals and 3 sepals).
- Polyembryony: Observed, as multiple embryos can be found in the seeds.
- Conclusion: Meets both criteria.

### Step 4: Final Conclusion
Based on the analysis, the plant that has trimerous flowers and exhibits polyembryony in its seeds is **Allium**.
