2. Intercalary meristem is present in the nodal region.
3. These meristems are found in monocotyledons such as grasses.
4. They are present in between the permanent tissues.
5. They are derived from the apical meristem.

3. Lateral meristems

1. Their function is to increase the thickness of the stem and root.
2. Lateral meristem is present along the longitudinal axis of stem and root.
