In the Cucurbitaceae family, which belongs to the order Cucurbitales, the seeds are positioned within an inferior ovary via parietal placentation.1

In this arrangement, the ovules—which develop into seeds after fertilization—are attached directly to the inner walls of the ovary or to extensions of the ovary wall. This is a characteristic feature of the family, as members of the Cucurbitales are traditionally grouped with other families that exhibit this specific type of ovule placement.231
