Name the vegetative propagule in Bryophyllum.

Answer

### Step-by-Step Solution:

1. **Understanding Vegetative Propagation**:
- Vegetative propagation is a method of asexual reproduction where new plants are produced from the vegetative parts (like roots, stems, or leaves) of a parent plant.

2. **Identifying Bryophyllum**:
- Bryophyllum is a genus of plants known for their unique method of vegetative reproduction.

3. **Determining the Vegetative Propagule**:
- In Bryophyllum, the vegetative propagule is specifically the leaf.

4. **Characteristics of the Leaf**:
- The leaves of Bryophyllum are broad and have several notches along their edges.

5. **Role of Notches**:
- Each notch on the leaf contains a bud, referred to as bifacial buds.

6. **Process of Propagation**:
- When these buds come into contact with the soil, they can germinate and develop into new plants.

7. **Adventitious Roots**:
- The new plants that grow from the buds have adventitious roots, which help anchor them and provide nutrients.

### Final Answer:
The vegetative propagule in Bryophyllum is the leaf.
