Short description: Taxonomic rank
A subvariety (Latin: subvarietas) in botanical nomenclature is a taxonomic rank. They are rarely used to classify organisms.
Plant taxonomy
Subvariety is ranked:
- below that of variety (varietas)
- above that of form (forma).
Subvariety is an infraspecific taxon.[1]
Name
Its name consists of three parts:
- a genus name (genera)
- a specific epithet (species)
- an infraspecific epithet (subvariety)
To indicate the subvariety rank, the abbreviation "subvar." is put before the infraspecific epithet.

Further ranks may also be intercalated or added, provided that confusion or error is not thereby introduced."
