Section (biology)

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

The hierarchy of biological classification's eight major taxonomic ranks. Intermediate minor rankings are not shown.

In botanyEdit

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

In zoologyEdit

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

In bacteriologyEdit

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]
