The naming of cultivars is an important aspect of cultivated plant taxonomy, and the correct naming of a cultivar is prescribed by the Rules and Recommendations of the "International Code of Nomenclature for Cultivated Plants" (ICNCP, commonly denominated the "Cultivated Plant Code"). A cultivar is given a cultivar name, which consists of the scientific Latin botanical name followed by a cultivar epithet. The cultivar epithet is usually in a vernacular language. For example, the full cultivar name of the King Edward potato is "Solanum tuberosum" 'King Edward'. 'King Edward' is the cultivar epithet, which, according to the Rules of the "Cultivated Plant Code", is bounded by single quotation marks.
