 (a name in three parts). The Variety taxonomy is most often used in classifying plants, but is on occasion used colloquially and industrially to differentiate between pedigree bloodlines in the animal kingdom as well. Official zoological nomenclature does not recognize the rank of variety, only sub-species.

A variety will have an appearance distinct from other varieties, but will hybridize freely with those other varieties (if brought into contact). Usually varieties will be geographically separate from each other, or as in the case of animals, bred carefully in controlled segregation from other varieties.

Example: The pincushion cactus, Escobaria vivipara (Nutt.) Buxb., is a wide-ranging variable species occurring from Canada to Mexico, and found throughout New Mexico below about 2600 m. Nine varieties have been described. Where the varieties of the pincushion cactus meet, they intergrade. The variety Escobaria vivipara var. arizonica is from Arizona, while Escobaria vivipara var. neo-mexicana is from New Mexico.
