2. **Identification of Rachis in Leaves**: In a compound leaf, the rachis is the part that connects the leaflets to the main stem. It is important to visualize this structure to understand its role.

3. **Types of Leaves**: Rachis is specifically found in compound leaves. A compound leaf is one that is divided into multiple leaflets, as opposed to a simple leaf which has a single blade.

4. **Specific Type of Compound Leaf**: Among compound leaves, the rachis is particularly associated with pinnately compound leaves. In pinnately compound leaves, the leaflets are arranged on either side of the rachis, resembling a feather.

5. **Conclusion**: Therefore, to summarize, rachis is present in compound leaves, and more specifically, it is found in pinnately compound leaves.
