Answer

**Step-by-Step Solution:**

- Bisporangiate stamens refer to stamens that contain two microsporangia (pollen sacs). This means that each stamen has the potential to produce two types of microspores, which develop into male gametes.

2. **Anatomy of the Anther**:
- The anther is a part of the stamen where microsporangia are located. In a bisporangiate anther, you would typically find two microsporangia. The anther consists of several layers including the epidermis, endodermis, middle layers, and tapetum, which provides nourishment.

3. **Examples of Plants**:
- To identify which plants have bisporangiate stamens, we can look at various examples:
- **Lily**: This plant has tetrasporangiate stamens, meaning it has four microsporangia.
- **Datura**: Similar to lilies, Datura also has tetrasporangiate stamens.
- **Hibiscus**: This plant is known to have bisporangiate stamens, with two microsporangia.
- **Beans**: Beans also have tetrasporangiate stamens.

4. **Conclusion**:
- Based on the analysis of the examples, the correct answer to the question "Bisporangiate stamens are seen in" is **Hibiscus**.

**Final Answer**: Hibiscus
