Question

⊕ $P_{3+3}{A}_{3+3}{G}_{\left(3\right)}$ is the floral formula of family liliaceae. What does $P_{3+3}$ indicate?

• A. Perianth
• B. Calyx and perianth
• C. Corolla and perianth
• D. tepals in two whorls

Answer 1

Answer: (A), (D)

The correct options are
A Perianth
D tepals in two whorls

Perianth is the outer two whorls of the flower consisting of calyx and corolla. In liliaceae family, calyx and corolla are united and are hence called tepals, therefore they are not represented as separate whorls with K and C respectively. $P_{3+3}$ indicates the tepals present in two whorls consisting of 3 floral appendages each.
