11. Floral Formulas K = calyx C = corolla A = androecium G = gynoecium Using the 4 whorls of floral parts as our reference Calyx (sepals) Corolla (petals) Androecium (stamens) Gynoecium (pistils)

12. Number of Parts K 5 = calyx of 5 sepals C 6 = corolla of 6 petals A 10 = androecium of 10 stamens G 2 = gynoecium of 2 carpels C = corolla missing A 4[5] = androecium usually of 4 stamens, rarely 5

13. Symmetry K = calyx actinomorphic (radially) C = corolla actinomorphic Kz = calyx zygomorphic (bilaterally) Cz = corolla zygomorphic Ovary Position G = ovary superior; flower hypogenous or perigynous G = ovary inferior; flower epigynous - G - = ovary half-inferior G = ovary either superior or inferior
