Floral formula method employs standardized symbols summarizing organization of floral whorls, merosity and symmetry for concise comparison across taxa. Circle with small cross inside ⊕ indicates actinomorphic or radially symmetrical flower possessing multiple planes of symmetry, example Solanum tuberosum, Brassica campestris with regular corolla. Zygomorphic symmetry represented by % or arrow showing single plane symmetry like Faboideae and Lamiaceae with bilateral organization adapted for bee pollination. Spiral arrangement, missing whorls, ovary position conveyed through other symbols with understanding ⊕ essential for taxonomy keys.
