Summary Leaf epidermis of grasses is structurally elaborate and quite important in modern systematics of the Poaceae. Available techniques used in preparing leaf epidermis for microscopic studies are time‐consuming and do not always produce adequate preparations. A simple and convenient technique is proposed in this paper which requires the application of a film of clear nail polish directly to the leaf surface. The impressions left on the polish film after drying produce an excellent detailed image of the epidermis. This technique is also applicable to other plant families.
