 | | This species name is called a binomial because, in fact, it is two words: the genus and the specific epithet. |
 | | If this variation is sufficient to warrant naming a new species, then a new species is named; but if the variation is minor or there is a broad range of overlap, a subspecies, variety, or form may be named. |
 | | When one of these ranks is recognized, its name is formed by using the species name followed by "subsp.," "var.," or "f.," an additional epithet, and the name of the author of the subspecies, variety, or form. |
