Sunken stomata is commonly found in leaves of ___________.
Nerium
Sunken stomata are commonly found in leaves of Nerium. This is an adaptation of the leaves to reduce excessive transpiration. The leaf is modified such that the stomata are in a pit and shielded from the dry, water-sucking winds. There might also be some hair structures that are present, which may further decrease the inflow of the air near the stomata, thus, minimizing the rate of transpiration.
