ovary position (floral)

Describes the position of the ovary in a flower relative to the whorls of the perianth (calyx/sepals and corolla/petals). A superior ovary describes an ovary that sits above where the perianth is attached to the floral structure; an inferior ovary describes an ovary that sits below the point of attachment of the perianth and stamens - and are attached at the top of the ovary, with the exposed style and stigma ; a perigynous ovary describes an ovary that is surrounded by floral parts (a calyx tube) that is attached to the perianth and stamens around the ovary, but not attached - making the ovary appear more or less half exposed .
