The character, too, of the cellular tissue, that forms the epidermis of leaves, and is stretched upon the framework of veins, is very varieddepending much upon the form of this framework-and is sometimes smooth and glossy, and at other times dull and curiously crumpled or otherwise relieved from uniformity.
