If the gynoecium is present at the topmost position of the thalamus above the rest of floral parts, then the flower is described as:
(a) hypogynous
(b) perigynous
(c) epigynous
In the hypogynous flower the gynoecium occupies the highest position while the other parts are situated below it. The ovary in such flowers is said to be superior, e.g., mustard, china rose and brinjal.
