Solution:

A flower may be hypogynous, perigynous or epigynous on the basis of position of calyx, corolla and androecium in respect to the ovary. Ovary occupies the highest position in hypogynous flower while other parts are situated below the ovary. In perigynous flowers gynoecium is situated at the centre while other parts are situated on the rim of the thalamus. In epigynous flowers ovary is completely enclosed by thalamus, other floral parts arise above the ovary. Perigynous flowers are found in Plum and Peach.
Hypogynous flowers are found in Hibiscus and Mustard.
