Corolla is cruciform and unguiculate in

Options

A. Liliaceae
B. Solanaceae
C. Asteraceae
D. Brassicaceae.

Answer

To determine which family has a cruciform and unguiculate corolla, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Cruciform**: This term refers to a cross-shaped arrangement of petals. In botanical terms, it typically means that the flower has four petals arranged in a cross shape.
- **Unguiculate**: This refers to petals that have a narrow base (the claw) and a broader part (the limb), resembling a claw.

2. **Identify the Family**:
- The question asks for a family where the corolla is cruciform and unguiculate.
- The family that is known for having a cruciform corolla is **Brassicaceae** (also known as the mustard family).

3. **Characteristics of Brassicaceae**:
- The flowers in this family typically have four petals that are arranged in a cross shape, which makes them cruciform.
- The petals are usually free (polypetalous) and can be described as unguiculate due to their claw-like structure.

4. **Eliminate Other Options**:
- **Liliaceae**: This family can have either fused (gammopetalous) or free petals, but it does not typically have a cruciform shape.
- **Solanaceae**: This family generally has five petals and does not exhibit a cruciform arrangement.
- **Asteraceae**: This family is characterized by tubular or star-shaped corollas, which do not match the description.

5. **Conclusion**:
- Based on the characteristics outlined, the correct answer is **Brassicaceae**.

### Final Answer:
The corolla is cruciform and unguiculate in the **Brassicaceae** family.
