Subvariety

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.

Name
Its name consists of three parts:
 * 1) a genus name (genera)
 * 2) a specific epithet (species)
 * 3) an infraspecific epithet (subvariety)

To indicate the subvariety rank, the abbreviation "subvar." is put before the infraspecific epithet.
