Plants that are found in water are known as aquatic plants. They possess features which enable them to get rid of excess water as well as to stay afloat on water. For example, their leaves are waxy to enable them remain afloat.

Plants found on land are terrestrial plants and possess features that enable them survive on land. They possess features which prevent excessive water loss such as waxy cuticle.

Therefore, the evidence that paleobotanists look for that indicates the movement of plants from water to land is the possession of waxy cuticle to decrease evaporation from leaves.
