The outer surface of herbaceous parts of plants. It consists of the outer walls of the epidermal cells. These walls are much thickened and cutinized. Minute waxy rods upon the cuticularized surface of many fruits, such as the grape and plum, give to them their peculiar bloom. The Cuticle is nearly impervious to water. The preservation of fruits depends in large measure upon the retention of moisture by the Cuticle. Cacti and other desert plants have their epidermis remarkably cuticularized.
