In biology a section (Latin: sectio) is a taxonomic rank that is applied differently in botany and zoology.

In botany

Within flora (plants), 'section' refers to a botanical rank below the genus, but above the species:

• Domain > Kingdom > Division > Class > Order > Family > Tribe > Genus > Subgenus > Section > Subsection > Species

In zoology

Within fauna (animals), 'section' refers to an uncommonly used zoological rank below the order, but above the family:

• Domain > Kingdom > Phylum > Class > Order > Section > Family > Tribe > Genus > Species

In bacteriology

The International Code of Nomenclature for Bacteria states that the Section rank is an informal one, between the subgenus and species (as in botany).^[1]
