[figure] is the floral formula of
- Petunia
- Brassica
- Allium
- Sesbania.
Answer
(1) Petunia
Solution
Reading the given formula: means an actinomorphic, bisexual flower; K(5) means five united sepals and C(5) five united petals; A5 joined to the corolla by an arc means five epipetalous stamens; and G(2) means a bicarpellary, syncarpous gynoecium with a superior ovary.
As per NCERT, this is the floral formula of Solanaceae, and Petunia belongs to Solanaceae.
It cannot be the others, because Brassica (Brassicaceae) has a tetradynamous androecium, Allium (Liliaceae) a trimerous perianth and Sesbania (Fabaceae) a zygomorphic flower.
∴ The formula is of Petunia.
