- In a racemose inflorescence, flowers are borne on a central axis (peduncle) and are arranged in an acropetal manner.

3. **Conclusion**:
- Based on the characteristics outlined, the inflorescence formed by pedicellate bisexual flowers borne acropetally on an elongated peduncle is called a **Raceme**.

### Final Answer:
The inflorescence is called a **Raceme**.
