List 4 ways in which the Oleander Leaf is adapted to restrict water loss?

This is by evaporation through the cuticle and transpiration through its stomata. Thanks for all your help :D

List 4 ways in which the Oleander Leaf is adapted to restrict water loss?
Oleander leaves have a coating (waxy) on their upper surface, which limits evaporation. They also have a relatively small surface area per leaf, which also limits the evaporation. The stoma on the bottom side can be opened or closed to regulate the release of water from the leaf. Also, with limited number of veins per leaf, less water flows to the cells, thereby reducing unnecessary water loss.
