“…Interest in epicuticular wax is by no means a new phenomenon. Similar studies of other protective coverings, such as coverings of pollen grains (4), mammalian skin [sheep (5) and man (6)], and arthropodal exoskeleton cuticle [for example, cockroach (7)], are being pursued and are bringing to light interesting similarities and contrasts. Chibnall and his colleagues (3), in the period 1930 to 1950, examined the chemical composition of the waxes by means of fractional crystallizations, precision melting point determinations, and x-ray powder diagrams.…”

The external surface of the higher plants comprises a cuticular layer covered by a waxy deposit. This deposit is believed to play a major part in such phenomena as the water balance of plants and the behavior of agricultural sprays. The wax contains a wide range of organic compounds. These complex mixtures are amenable to modern microchromatographic and microspectrometric analytical procedures. 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. This fascinating subject, in which the disciplines of botany, biochemistry, chemistry, and physics overlap and interact, is still in a very active state. Much remains to be learned about the composition and fine structure of the wax deposits, and, for this, experimental study of wax crystallization and permeation through artificial membranes will be required. Enzymic studies, radiolabeling, and electron microscopy will be needed to reveal the mode of biogenesis of the wax constituents and their site of formation and subsequent pathway through the cuticle to the leaf surface.
