likoan [24]

As the leaf surface area decreases ; Number of leaves increase inmost plants.

As the leaf surface area increases, the rate of transpiration increases as well because leaves with large surface areas have bigger stomata. also the smaller the leave surface area of a plant/tree the denser the leaves the plants/tree will have.
