Variety (botany)

In botanical nomenclature, variety (abbreviated var.; in Latin: varietas) is a taxonomic rank below that of species: as such, it gets a three-part infraspecific name.

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 2,600 metres (8,500 ft). 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.

Definitions

The term is defined in different ways by different authors.[1] 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.
