When the calyx, corolla and androecium arise below the ovary, the flower is called hypogynous. In these flowers the ovary is superior, e.g., mustard, China rose and brinjal. In perigynous condition of flower, the calyx, corolla and androecium arise from the around of ovary. In these flowers the ovary is semi inferior, e.g., plum, rose and peach. When the calyx, corolla and androecium arise from the top of the ovary, the flower is called epigynous. In these flowers the ovary is inferior, e.g., guava, cucumber and the ray florets of sunflower.
