The floral formula $\oplus$ ⚥ $K_{(5)}\overset{\frown}{C_{(5)}A_5}\underline{G}_{(2)}$ is that of
A
Tobacco
B
Tulip
C
Soybean
D
Sunnhemp
Detailed Solution
The formula describes an actinomorphic ($\oplus$), bisexual flower with five united sepals $K_{(5)}$, five united petals $C_{(5)}$, five epipetalous stamens $A_5$ and a bicarpellary, syncarpous, superior ovary $\underline{G}_{(2)}$.
These are the characters of the family Solanaceae, to which tobacco, tomato, potato, brinjal, chilli and petunia belong.
Tulip belongs to Liliaceae: $\oplus$ ⚥ $P_{3+3}A_{3+3}\underline{G}_{(3)}$
Soybean and sunnhemp belong to Fabaceae: % ⚥ $K_{(5)}C_{1+2+(2)}A_{(9)+1}\underline{G}_1$
Hence the floral formula is that of tobacco.
