Subvariety

A subvariety (Latin: subvarietas) in botanical nomenclature is a taxonomic rank. They are rarely used to classify organisms.

For (two distinct) mathematical uses, see algebraic variety and variety (universal algebra).

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:

  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.

If a greater number of ranks of taxa is desired, [...a]n organism may thus be assigned to taxa of the following ranks (in descending sequence): [... genus, ... species, subspecies,] variety (varietas), subvariety (subvarietas), form (forma), and subform (subforma). ... 4.3. Further ranks may also be intercalated or added, provided that confusion or error is not thereby introduced.
