C. Dicots with fused petals
D. Monocots with free perianth

Answer

To answer the question regarding the common character of plants included under the series Thalamiflorae, Discifloræ, and Calyciflorae, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Plant Classification**:
- Plants are classified into various categories. The kingdom Plantae is divided into divisions, including Angiosperms and Gymnosperms. Angiosperms are further divided into two main groups: dicots and monocots.

2. **Focus on Dicotyledons**:
- The series Thalamiflorae, Discifloræ, and Calyciflorae are all part of the dicotyledons (dicots). This means they share certain characteristics typical of dicots.

3. **Identifying the Series**:
- Thalamiflorae, Discifloræ, and Calyciflorae are classified under the polypetalous group of dicots. This classification indicates that these plants have flowers with distinct, free petals.

4. **Common Character**:
- The common character among these series is that they all have flowers with a specific arrangement of floral parts. In particular, they exhibit a pattern where the petals are not fused together, which is a characteristic of polypetalous dicots.

5. **Conclusion**:
- Therefore, the common character of the plants included under the series Thalamiflorae, Discifloræ, and Calyciflorae is that they possess flowers with free (unfused) petals.

### Final Answer:
The common character of the plants included under the series Thalamiflorae, Discifloræ, and Calyciflorae is that they have flowers with free petals (polypetalous).
