The division ( divisio ) is a hierarchical level of the biological system .
In botany , according to the ICBN, it is provided as the highest rank below the realm ( Regnum ) or Unterreich ( Subregnum ). Divisions end in -phyta for plants and -mycota for mushrooms. The department in botany corresponds to the stem ( phylum ) in the zoological system and is accordingly sometimes referred to as phylum in botany .
In the zoological system , the department was sometimes used as a rank between the kingdom and the tribe. Other authors named other degrees of division (divisio), partly between class and order, some also between order and family. Others have used the term to subdivide genres. These uses are no longer common.
