In which of the families the stamens are in two whorls and epiphyllous :-

Options

A. Malvaceae
B. Solanaceae
C. Liliaceae
D. Caesalpinoideae

Answer

To solve the question of which family has stamens in two whorls and is epiphyllous, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Stamens**: The male reproductive part of a flower, typically consisting of a filament and an anther.
- **Whorls**: Refers to the arrangement of floral organs. Two whorls mean there are two distinct groups of stamens.
- **Epiphyllous**: This condition means that the stamens are attached to the perianth (the outer parts of the flower, which include petals and sepals).

2. **Identify the Families**:
- The options given are Malvaceae, Solanaceae, Liliaceae, and Cisalpiniode.

3. **Analyze Each Family**:
- **Malvaceae**: In this family, stamens are usually grouped together in one whorl, so it does not fit the criteria of two whorls.
- **Solanaceae**: This family has an epipetalous condition, where stamens are fused with the petals, forming only one whorl. Thus, it does not satisfy the requirement.
- **Liliaceae**: In this family, the stamens are arranged in two whorls and are epiphyllous, meaning they are attached to the perianth. This fits the criteria perfectly.
- **Cisalpiniode**: This family has a nine plus one arrangement of stamens, which can form two whorls, but it does not have the epiphyllous condition.

4. **Conclusion**:
- The family that has stamens in two whorls and is epiphyllous is **Liliaceae**.

### Final Answer:
The correct answer is **Liliaceae**.
