C. Allogamy
D. Cleistogamy.

Answer

**Step-by-Step Text Solution:**

1. **Understanding Xenogamy**:
- Xenogamy refers to the process of fertilization in plants where pollen is transferred from the anther of one flower to the stigma of another flower on a genetically different plant.

2. **Identifying the Options**:
- The options provided are:
- Autogamy
- Homogamy
- Allogamy
- Clistogamy

3. **Defining the Options**:
- **Autogamy**: This is a type of self-pollination where pollen from the same flower fertilizes the ovule of that flower.
- **Homogamy**: This refers to the condition where flowers are capable of self-fertilization due to the arrangement of their reproductive organs.
- **Allogamy**: This is synonymous with cross-pollination, where pollen is transferred between different plants, promoting genetic diversity.
- **Clistogamy**: This refers to a type of self-pollination that occurs in closed flowers, preventing cross-pollination.

4. **Analyzing the Correct Answer**:
- Since xenogamy involves the transfer of pollen between different plants (cross-pollination), the correct term that describes this process is **Allogamy**.

5. **Conclusion**:
- Therefore, the correct answer to the question "Xenogamy is essentially a type of" is **Allogamy**.
