Answer

To solve the problem, we need to identify how many of the listed plants belong to a family whose flowers have six tepals and six epitepalous stamens. The families we are considering are Liliaceae and Solanaceae, as these families are known for having these floral characteristics.

### Step-by-step Solution:

2. **List the plants**: The plants given in the question are:
- Colchicine
- Aloe
- Gram
- Potato
- Gloriosa
- Tomato
- Sweet pea
- Asparagus
- Groundnut
- Tulip

3. **Determine the family for each plant**:
- **Colchicine**: Belongs to the Liliaceae family.
- **Aloe**: Does not belong to either Liliaceae or Solanaceae.
- **Gram**: Does not belong to either Liliaceae or Solanaceae.
- **Potato**: Belongs to the Solanaceae family.
- **Gloriosa**: Belongs to the Liliaceae family.

- **Asparagus**: Belongs to the Asparagaceae family.
- **Groundnut**: Does not belong to either Liliaceae or Solanaceae.
- **Tulip**: Belongs to the Liliaceae family.

4. **Count the plants**: Now we count how many of these plants belong to either the Liliaceae or Solanaceae families:
- Colchicine (Liliaceae)
- Potato (Solanaceae)
- Gloriosa (Liliaceae)
- Tomato (Solanaceae)
- Tulip (Liliaceae)

Thus, we have a total of **5 plants** that belong to the families with the specified floral characteristics.

### Final Answer:
