This term often causes confusion, as it is used differently and often incorrectly in the relevant literature. According to the "Duden" a variety (lat. Varietas, engl. variety or variation, sometimes also race) is a slightly different form of a species (lat. species) within a biological system. In the "Roche Lexicon of Medicine", a variety is a subspecies of the subspecies, which was also called type in the past. A variant (variation, variation, variety) means a deviation from the comparative or standard type or norm (slightly modified form of something). However, this term is not used in connection with the botanical order. In general language use, however, there is hardly any difference between the two terms variety and variant.
