3. **Research Known Families**: From biological studies, we know that certain families are classified as basal angiosperms. These families often exhibit primitive characteristics.

4. **Identify Families Without Vessels**:
- The **Winteraceae** family is known to be a basal angiosperm family that lacks vessels.
- Other families like **Tetracentraceae** and **Trachodendraceae** are also basal angiosperms, but they do have vessels.
