{{short description|Taxonomic rank}}
{{Biological classification}}
In [[biology]] a '''section''' ({{langx|la|sectio}}) is a [[taxonomic rank]] that is applied differently in [[botany]] and [[zoology]].
==In botany==
{{Main|Section (botany)}}
Within flora (plants), 'section' refers to a ''botanical'' rank below the genus, but above the species:
* [[domain (biology)|Domain]] > [[kingdom (biology)|Kingdom]] > [[division (botany)|Division]] > [[class (biology)|Class]] > [[order (biology)|Order]] > [[family (biology)|Family]] > [[tribe (biology)|Tribe]] > [[Genus]] > Subgenus > '''[[Section (botany)|Section]]''' > Subsection > [[Species]]
==In zoology==
Within fauna (animals), 'section' refers to an uncommonly used ''zoological'' rank below the order, but above the family:
* [[domain (biology)|Domain]] > [[kingdom (biology)|Kingdom]] > [[Phylum]] > [[class (biology)|Class]] > [[order (biology)|Order]] > '''Section''' > [[family (biology)|Family]] > [[tribe (biology)|Tribe]] > [[Genus]] > [[Species]]
The rank of [[Superfamily (taxonomy)|Superfamily]] is commonly adopted instead.
==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).<ref>{{citation |chapter-url=https://www.ncbi.nlm.nih.gov/books/NBK8808/ |title=International Code of Nomenclature of Bacteria: Bacteriological Code, 1990 Revision |chapter = Chapter 3, Rules of Nomenclature with Recommendations, Rule 11}}</ref>
