►There are many Classes, Orders, and Families of plants.

►Even though each plant is categorized using at least seven names, we call plants by only their last two scientific names: Genus, SpeciesGenus, Species.


►This is a naming system called Binomial NomenclatureBinomial Nomenclature (which means a two-name system of identifying).
