The external surface of the higher plants comprises a cuticular layer covered by a waxy deposit. The few surveys which have been made of the species distribution of certain classes of constituents indicate that such distribution may be of limited taxonomic value; however, the wax composition of a species may differ for different parts of the same plant and may vary with season, locale, and the age of the plant. Stay Connected to Science. This deposit is believed to play a major part in such phenomena as the water balance of plants and the behavior of agricultural sprays. Other protective functions may include minimizing mechanical damage to leaf cells and inhibiting fungal and insect attack.
