Carl Linnaeus's garden at Uppsala, Sweden Title page of Species Plantarum, 1753. The International Code of Nomenclature for algae, fungi, and plants (ICN or ICNafp) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those "traditionally treated as algae, fungi, or plants". [1]:
Botanical nomenclature is merely the body of rules prescribing which name applies to that taxon (see correct name) and if a new name may (or must) be coined. Plant taxonomy is an empirical science, a science that determines what constitutes a particular taxon (taxonomic grouping, plural: taxa): e.g.
Following the structure of the Botanical Code, the ICNCP is set out in the form of an initial set of Principles followed by Rules and Recommendations that are subdivided into Articles. Amendments to the ICNCP are prompted by international symposia for cultivated plant taxonomy which allow for rulings made by the International Commission on the ...
From the mid-19th century onwards, there were several initiatives to arrive at worldwide-accepted sets of rules. Presently nomenclature codes govern the naming of: Algae , Fungi and Plants – International Code of Nomenclature for algae, fungi, and plants ( ICN ), which in July 2011 replaced the International Code of Botanical Nomenclature ...
International Code of Nomenclature for algae, fungi, and plants (ICN), formerly the International Code of Botanical Nomenclature (ICBN) International Code of Nomenclature of Bacteria (ICNB) International Code of Nomenclature for Cultivated Plants (ICNCP)
Note that nomenclature for botany and zoology is independent, and the rules of priority regarding homonyms operate within each discipline but not between them. Thus, an animal and a plant can bear the same name, which is then called a hemihomonym. There are formal provisions for making exceptions to the principle of priority under each of the ...
The 1905 rules became increasingly outdated. They soon sold out, and it became increasingly difficult to obtain to a complete set of the Rules with all amendments. [14] In Copenhagen 1953 the French and English texts of the rules were declared of equivalent official force, and a declaration was approved to prepare a new compilation of the rules.
For a proposed infraspecific name to be legitimate it must be in accordance with all the rules of the ICN. [14] Only some of the main points are described here. A key concept in botanical names is that of a type. In many cases the type will be a particular preserved specimen stored in a herbarium, although there are other kinds of type. Like ...
