• After describing various parts of plant, a floral diagram and a floral formula are presented, which is represented by some symbols.
• In the floral formula, Br stands for bracteate K stands for calyx , C for corolla, P for perianth, A for androecium and G for Gynoecium, G for superior ovary and G for inferior ovary, for male, for female , ⊕ for actinomorphic and for zygomorphic nature of flower.
• Fusion is indicated by enclosing the figure within bracket and adhesion by a line drawn above the symbols of the floral parts.
• A floral diagram provides information about the number of parts of a flower, their arrangement and the relation they have with one another.
• The position of the mother axis with respect to the flower is represented by a dot on the top of the floral diagram.
• Calyx, corolla, androecium and gynoecium are drawn in successive whorls, calyx being the outermost and the gynoecium being in the centre.
• Floral formula also shows cohesion and adhesion within parts of whorls and in between whorls.
