When the sepals, petals and stamens are attached below the ovary, the flower is hypogynous and the ovary is in a superior position (Plate 7.3, A-C). When these structures are attached above the ovary, the flower is epigynous and the ovary is in an inferior position (Plate 7.3, D-F). In some flowers, the ovary is surrounded by a cup-shaped hypan-thium derived either from the fusion of the sepals, petals, and stamens, or an extension of the receptacle to which the floral parts are attached. These flowers are called perigynous (Plate 7.3, G-I). Although not part of the true seed, the ovary and other floral parts that
