Answer» It is sometimes found convenient to describe a FLOWER by a simple and concise formula known as the floral formula. In this formula K represents calyx, C=corolla, P= perianth, A=androccium, G=Gynoecium. It is sometimes found convenient to describe a flower by a simple and concise formula known as the floral formula. In this formula K represents calyx, C=corolla, P= perianth, A=androccium, G=Gynoecium.The number of members of a whorl is written after the symbol for a whorl, ∞ SIGNIFIES a large and indefinite number. If the members are present in different whorls, the different whorls are written separately with a + sign between them. It is sometimes found convenient to describe a flower by a simple and concise formula known as the floral formula. In this formula K represents calyx, C=corolla, P= perianth, A=androccium, G=Gynoecium.The number of members of a whorl is written after the symbol for a whorl, ∞ signifies a large and indefinite number. If the members are present in different whorls, the different whorls are written separately with a + sign between them.Thus, A2+2 means androecium of four stamens in two whorls of two each. When members are united (cohesion), the number is placed within first BRACKETS. Adhesion is expressed by a line JOINING the two whorls.
