The upper part of this ovary is usually prolonged into a stalk called a 8tyle (Fig. 3, A); the apex of the style is with- out the epidermis, or skin, which covers the rest of the plant; it is therefore called a Stigma (Gr. brand), because it is like flesh seared by a hot iron. These,-=-ovary, style, and stigma, âtaken together, form the Pistil; but they are merely pro- tective; the ovule is the only essential part. When the style is wanting, as in the Vine (Fig. 4, i), the stigma is termed Sessile, that is, seated (on the
