Above-ground epidermal surfaces of vascular plants are covered by a lipophilic layer known as the cuticle. Plant cuticles are composed of cutin ( cutin biosynthesis) and cuticular wax. The major components of cuticular wax are very long chain fatty acids (chain length is greater than 18 carbon) and very long chain fatty acid derived aldehydes, alkanes, secondary alcohols, ketones, primary alcohols, and wax esters. The composition of cuticular wax varies among species and even within species in different tissues and at different developmental stages.
