To solve the question regarding which plant reproduces vegetatively by epiphyllous buds (adventitious), we can follow these steps:

### Step 1: Understand the Term "Epiphyllous Buds"
Epiphyllous buds are buds that arise from the leaves, specifically from the adaxial (upper) surface. These buds can develop into new plants when they fall off the parent plant.

**Hint:** Look for plants that have the ability to produce buds from their leaves.

### Step 3: Evaluate Each Plant
- **Sweet Potato:** Reproduces through tubers and not through epiphyllous buds.
- **Potato:** Reproduces through tubers (eyes) and does not have epiphyllous buds.
- **Onion:** Reproduces through bulbs and does not produce buds from leaves.
- **Kalanchoe:** Known for producing epiphyllous buds on its leaves, which can fall off and grow into new plants.

**Hint:** Identify which plant is known for producing buds from its leaves.

### Step 4: Conclusion
Based on the analysis, Kalanchoe is the plant that reproduces vegetatively by epiphyllous buds.
