Floral formulae are symbolic and numeric representations of different parts of a flower. It provides information about the type and number of different parts of the flower, symmetry type, position of ovary w.r.t. other whorls, and inter-relationships between different floral whorls etc.
The following are some letters and symbols used in the floral formula.
Br – bracteate
K – calyx
C – corolla
P – perianth
A – androecium
G - Gynoecium
G - superior ovary
G - inferior ovary
♂ - male
♀ - female
⚥ - bisexual plants
⊕ for actinomorphic flower
zygomorphic flower.
Fusion is indicated by enclosing the figure within bracket
Adhesion is indicated by a line drawn above the symbols of the floral parts.
The floral formula of Fabaceae is as follows,
The flowers are zygomorphic, bisexual, Calyx has five fused sepals, corolla is papilionaceous (1 standard, 2 wing petas, 2 fused keel petals), diadelphous stamens, Gynoecium is monocarpellary with a superior ovary.
The floral formula of Solanaceae is as follows,
Flowers are actinomorphic and bisexual, Calyx includes 5 fused sepals, Corolla has 5 fused petals, Stamens are 5 in number, epipetalous, Gynoecium is bicarpellary, apocarpous with a superior ovary.
The floral formula of Liliaceae is as follows,
Flowers are actinomorphic, bisexual. Perianth includes 6 fused tepals arranged in two rows, Stamens are 6 in number and epipetalous, Gynoecium is tricarpellary, syncarpous with a superior ovary .
The floral formula of Brassicaceae is as follows:
The flowers are actinomorphic, bisexual, Calyx includes 4 sepals arranged in two rows, polysepalous. Corolla includes 4 petals, polypetalous. Stamens are 6 in number arranged in 2 rows (tetradynamous), Gynoecium is bicarpellary, syncarpous with a superior ovary.
