Solution

1) Floral formula

⊕ ⚥ $K_{(5)} C_{(5)} A_{(5)} G_{(2)}$

$\begin{matrix} Symbols & Meaning \oplus & Actinomorphic ⚥ & Bisexual K_{(5)} & 5 sepals fused C_{(5)} & 5 petals fused A_{(5)} & K(5)5stamens fused G_{(2)} & 2 carpels syncarpous \end{matrix}$

2) Floral formula

Ф ⚥ $K_{(5)} C_{1 + 2 + (2)} A_{(9) + 1} G_{1}$

$\begin{matrix} Symbols & Meaning Ф & Zygomorphic ⚥ & Bisexual K_{(5)} & Sepals 5 fused C_{1 + 2 + (2)} & Petals 5 out which 2 is fused (Papilionaceous) A_{(9) + 1} & Stamen 10(9 fused and 1 free (Diadelphous) G_{1} & Carpel one in number Superior ovary \end{matrix}$

This is the characteristic floral formula of family Fabaceae
