Cuticle layer of a plant
Cuticles are a waxy coat made from the epithelial cells on a leaf. The top side of the leaf tends to be covered with more cuticle because it is exposed to the sun and the rain. The cuticle is made of an insoluble membrane covered with soluble waxes. Cutin is the best known component that makes up the cuticle membrane. The waxes on the cuticle are a mixture of hydrophobic compounds which is why when the cuticle has water on it the water only beads up. The picture above is of the top of a leaf of a plant covered with waxy cuticle.
