Explanation
The floral formula is a shorthand notation that represents the basic structure of a flower. It provides information about the number, arrangement, and fusion of floral parts. The symbols used in the formula represent different parts of the flower, and the numbers indicate their quantity.
In the case of Hibiscus, the flower has a pentamerous symmetry, which means that its floral parts are arranged in fives. The androecium is represented by the symbol A∞, which means that it has an infinite number of stamens. This is because the stamens are fused into a tube that surrounds the gynoecium. The ovary has five carpels, but they are fused into a single structure. The number 5 in the parentheses after G indicates that there are five chambers or locules in the ovary.
In the case of Brassica, the flower has a tetramerous symmetry, which means that its floral parts are arranged in fours. The androecium is represented by the symbol A2+4, which means that it has two short stamens and four long stamens. The ovary has two carpels, which are not fused. The number 2 in the parentheses after G indicates that there are two chambers or locules in the ovary.
