The role of the epidermis in leaf organization has not been extensively explored. As a surface covering it affords some protection, but this is due chiefly to the cuticular film which protects both the epidermal layer and underlying cells. The importance of the epidermis, as a tissue of living cells, is probably much greater than has been generally realized. For this reason observations and experiments providing further information about the epidermis are of special interest. The present paper summarizes a study of a blotch-type leaf mine in the upper side of a leaf (Eupatorium purpureum), with special reference to its epidermal cover. It seemed of importance, also, to record for general reference the detailed structure of this leaf from an herbaceous dicotyledon plant growing in partial shade.
