Sunken, covered, and encrypted stomata have been anecdotally linked with dry climates and reduced transpiration and therefore have been used to infer dry palaeoclimates from fossils. These stomatal crypts are located only on the underside of the leaves, where they experience less sun exposure and therefore less transpiration. Sunken stomata are not directly visible to the leaf surface. Desert plants are capable of reducing the amount of water they lose through transpiration because they have fewer stomata, the tiny pores that act as transpiration channels.
