Br $\oplus$ $⚥$ P_{3 + 3}A_{3 + 3} $G$ ₍₃₎

Br $\oplus$ $⚥$ Epi_{5 - 7} K₍₅₎ C₅A_{( $\infty$ )} $G$ ₍₅₎

Ebr $\oplus$ $⚥$ K_{2 + 2} C₄ A_{2 + 4} $G$ ₍₂₎

% $\oplus$ $⚥$ K₅ C₅ A₇_{+ 3} $G$ ₍₁₎

Solution

Br $\oplus$ $⚥$ Epi_{5 - 7} K₍₅₎ C₅A_{( $\infty$ )} $G$ ₍₅₎

The correct floral formula is Br $\oplus$ $⚥$ Epi_{5 - 7} K₅ C₅ A_{( $\infty$ )} $G$ ₍₅₎

The above formula belongs to Hibiscus rosa sinensis, member of Family- Malvaceae.

Br - Bracteate flowers

Epi - Ring of bracts that resemble calyx

$\oplus$ - actinomorphic symmetry

K₍₅₎ - 5 sepals which are fused

C₅ - 5 petals which are free

A_{( $\infty$ )} - numerous stamens and filaments which are fused

$G$ ₍₅₎ - 5 carpels which are fused and present in superior ovary.
