Infraspecific name agriculture or horticulture. Such names are regulated by the "International Code of Nomenclature for Cultivated Plants" (ICNCP). Although logically below the rank of species (and hence "infraspecific"), a cultivar name may be attached to any scientific name at the genus level or below. The minimum requirement is to specify a genus name. For example, "Achillea" 'Cerise Queen' is a cultivar; "Pinus nigra" 'Arnold Sentinel' is a cultivar of the species "P. nigra" (which is propagated vegetatively, by cloning).
