Answer

**Step-by-Step Solution:**

1. **Understanding Inflorescence**: Inflorescence refers to the arrangement of flowers on a stem or branch. It can be classified into two main types: racemose and cymose.

2. **Types of Inflorescence**:
- **Racemose**: In this type, flowers are arranged in an acropetal manner, meaning that the younger flowers are at the top and older flowers are at the bottom.
- **Cymose**: In this type, flowers are arranged in a basipetal manner, meaning that the younger flowers are at the bottom and older flowers are at the top.

3. **Identifying Unisexual Flowers**: Unisexual flowers are those that contain either male or female reproductive organs, but not both.

4. **Inflorescence with Unisexual Flowers**: The specific type of inflorescence that contains unisexual flowers is called **Cythium**.

5. **Characteristics of Cythium**: In a cythium, there is a cup-shaped structure where the female flower is located at the center, and the male flowers surround it. This unique arrangement allows for the presence of both male and female parts in the same flower.

6. **Example of Cythium**: A well-known example of this type of inflorescence is found in the plant genus **Euphorbia**.

7. **Final Answer**: Therefore, the inflorescence in which unisexual flowers are present is called **Cythium**.
