Describe the arrangement of floral members in relation to their insertion on the thalamus.

(N/A) Based on the position of the calyx,corolla,and androecium with respect to the ovary on the thalamus,flowers are classified into three types:
$1$. Hypogynous: In these flowers,the gynoecium occupies the highest position while the other floral parts are situated below it. The ovary is said to be superior. Examples: $China$ $rose$,$mustard$,and $brinjal$.
$2$. Perigynous: In these flowers,the gynoecium is situated at the center and other floral parts are arranged on the rim of the thalamus at the same level. The ovary is said to be half-inferior. Examples: $Plum$,$rose$,and $peach$.
$3$. Epigynous: In these flowers,the margin of the thalamus grows upward enclosing the ovary completely and getting fused with it. The other floral parts arise above the ovary. The ovary is said to be inferior. Examples: $Guava$,$cucumber$,and the ray florets of $sunflower$.
