What is Floral Formula?

A floral formula is a symbolic representation of a flower's structure using letters, numbers, and special symbols. It provides a concise way to describe the arrangement and number of floral parts.

Example Formula
% K(6) C1+2+(2) A(9) G2

This formula describes the flower's symmetry, sepals, petals, stamens, and carpels in a standardized format.

Formula Sequence

  • Bract: Br or Ebr
  • Bracteole: Brl or Ebrl
  • Symmetry: % (Radial) or ⊕ (Bilateral)
  • Sex: ♀ (Female), ♂ (Male), or ⚥ (Bisexual)
  • Calyx/Sepal: K<number> (Free or Fused)
  • Corolla/Petal: C<number> (Free or Fused)
  • Androecium: A<number> (Free or Fused)
  • Gynaecium: G<number> (Superior or Inferior Ovary)

Symbol Meanings

  • Numbers: Indicate quantity of parts
  • Parentheses (): Parts are fused together
  • Plus (+): Parts in different whorls
  • Underline: Superior ovary position
  • Overline: Inferior ovary position
  • ∞: Numerous parts (too many to count)

Understanding floral formulas helps botanists quickly identify and classify flowers based on their structural characteristics.
