In botany, the correct name according to the International Code of Nomenclature for algae, fungi, and plants (ICN) is the one and only botanical name that is to be used for a particular taxon, when that taxon has a particular circumscription, position and rank.[2] The name must be validly published, a process which is defined in no less than 16 Articles of the ICN.[6] Since taxonomists may disagree as to the circumscription, position or rank of a taxon, there can be more than one correct name for a particular plant.Thus this tree species will have a different correct botanical name for different people.[12] The Prokaryotic Code inherits many concepts, including that of a "correct name", from the ICN.
