In botanical nomenclature, variety (abbreviated var.; in Latin: varietas) is a taxonomic rank below that of species and subspecies, but above that of form.[1] As such, it gets a three-part infraspecific name. It is sometimes recommended that the subspecies rank should be used to recognize geographic distinctiveness, whereas the variety rank is appropriate if the taxon is seen throughout the geographic range of the species.[2]
4.1. 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|subforms*{8.21.06<sub-conformable, sub-conformer>}{6.4.18<sub-conform, sub-conforms><sub-conformal, sub-conformally, sub-conformable, sub-conformably, sub-conformant, sub-conformation, sub-conforming, sub-conformed, sub-conformer>}]. ... 4.3. Further ranks may also be intercalated or added, provided that confusion or error is not thereby introduced.
