In epigynous flowers, the thalamus is hollowed out in the form of a flask but its internal wall is fused with wall of the ovary. Only the style and stigmaof the pistal are obervable from the upper side. Other floral organs are borne at the top of ovary. The ovary or gynoecium is said to be inferior while other floral organs are superior, e.g., apple, sunflower, cucumber, etc.
