Floral

A floral diagram illustrates:

• The number of floral components
• Their spatial arrangement
• Their structural relationships

Key floral whorls – , , , and – are depicted in concentric circles from outermost to innermost.

The combined perianth (outer floral envelope) comprises undifferentiated and . When these structures are morphologically similar, each unit is termed a – the correct designation for the floral elements shown in the diagram.

Potato family (Solanaceae) has the following key characteristics:

• The flower is pentamerous (5 petals, 5 sepals, 5 stamens).
• The corolla is typically actinomorphic (radially symmetrical).
• The stamens are 5 in number, but there is fusion in the anthers, where 2 of the stamens are fused (antherconnate), making the floral formula A₅+₁ (5 stamens with 2 fused).
• The gynoecium is typically bicarpellary (2 carpels), and the ovary is superior.

Thus, the floral formula of plants in the potato family (Solanaceae) is ♀, K₅, C₅, A₅+₁, G₂, as given in option (B).
