The system is set up in a hierarchic manner, which means the classification pattern consist of so called categories of different significance on the basis of the biological species. The species is the only category specified by defined basic qualities.
In the beginning the superior categories had fixed names:
But attaching the prefix Super- and Sub- seventeen order categories have been achieved placed below the two kingdoms of animals and plants.
