Perigynous is a botanical term used to describe flowers where the sepals, petals, and stamens are attached to the rim of the ovary, with the ovary positioned below them. Synonymous terms that refer to this floral structure include epigynous, superior ovary, and perigynium. Epigynous emphasizes the positioning of the ovary above other flower parts. Similarly, the term superior ovary highlights the elevated position of the ovary. Perigynium, on the other hand, directs attention to the cup-like appearance of the flower, formed by the fused sepals, petals, and stamens. All these terms essentially describe the same floral structure, offering variety in language while expressing the same underlying botanical concept.
