Question

Perigynous flowers are found in:

• A. Rose
• B. Guava
• C. Cucumber
• D. China rose

Answer 1

The correct option is A Rose

Rose is a perigynous flower. If the gynoecium is located in the centre and other parts of the flower are located at the rim of the thalamus almost at the same level then it is called perigynous. Ovary will be half inferior in such flowers.

Perigynous

Guava and cucumber are epigynous. Ovary will be inferior in such flowers. The margin of the thalamus grows upward and encloses the ovary completely and gets fused with it. The other parts of the flower rise above the ovary in an epigynous flower.

Epigynous

China rose is a hypogynous flower. Ovary will be superior in such flowers. Gynoecium occupies the highest position and other parts are situated below in hypogynous flowers.
