Question:

Perigynous flowers are found in

Options:

1. Guava
2. Cucumber
3. China rose
4. Rose

Solution:

Perigynous flowers are found in rose. Flowers can be categorised based on the position of the ovary in relation to the other parts of the flowers. When the floral plants arise from a position below the ovary, the flower is said to be hypogynous (hypo=below; gynous=flower) and the ovary is superior, e.g. China rose. When the floral parts arise from a position above the ovary, the flower is epigynous (epi=above) and ovary is inferior, e.g. cucumber and guava. There is another special case of an inferior ovary where the bottom of sepals, petals and stamens are fused into a cup around the ovary called hypanthium (floral cup). Such, flower is termed as perigynous (peri = around), e.g. rose. Page 73, XI NCERT
