The formula is crucible
The diagram, along with the formula of the cruciferous flower, contains all the information about the structure of this plant.
H4l4t2+4p1: 4 cups, 4 petals, 6 stamens (2+4) and pestle.
The numbers indicate the number of elements, and the letters are the first in the name of the parts. From this formula it becomes clear that all plants with such a structure are bisexual, t.e. have pestles and stamens as the main parts of any flower.
The inflorescences of the cruciferous
