Answer

### Step-by-Step Solution

1. **Understanding Bulbs**:
- Bulbs are underground storage organs that can be classified into two types:
- **Tunicata (or Tunicate Bulbs)**: Example is the onion, which has a thin papery covering that protects its fleshy leaves.
- **Scaly Bulbs**: These do not have a protective papery covering and consist of a series of angular scales.

2. **Identifying Scaly Bulbs**:
- Scaly bulbs are characterized by their storage leaves that are thickened and fleshy, which serve as storage for nutrients.
- They are unprotected by any papery covering, unlike tunicate bulbs.

3. **Analyzing the Options**:
- The question provides four options: Lilium, Allium, Scylla, and Ginger.
- We need to determine which of these options contains scaly bulbs.

4. **Evaluating Each Option**:
- **Lilium**: Known as true lilies, they are characterized by scaly bulbs.
- **Allium**: This includes onions and garlic, which are tunicate bulbs, not scaly.
- **Scylla**: This is not commonly associated with scaly bulbs.
- **Ginger**: This is a rhizome, not a bulb.

5. **Conclusion**:
- Based on the characteristics of the bulbs and the evaluation of the options, the correct answer is **Lilium**.

### Final Answer:
Scaly bulb occurs in **Lilium**.
