Botanical nomenclature

Botanical nomenclature is the formal, scientific naming of plants. It is related to, but distinct from taxonomy. Plant taxonomy is concerned with grouping and classifying plants; botanical nomenclature then provides names for the results of this process. The starting point for modern botanical nomenclature is Linnaeus' Species Plantarum of 1753. Botanical nomenclature is governed by the International Code of Nomenclature for algae, fungi, and plants (ICN), which replaces the International Code of Botanical Nomenclature (ICBN). Fossil plants are also covered by the code of nomenclature.

Within the limits set by that code there is another set of rules, the International Code of Nomenclature for Cultivated Plants (ICNCP) which applies to plant cultivars that have been deliberately altered or selected by humans (see cultigen).

History and scope[]

Botanical nomenclature has a long history, going back beyond the period when Latin was the scientific language throughout Europe, to Theophrastus (c. 370–287 BC), Dioscorides (c. 40 – 90 AD) and other Greek writers. Many of these works have come down to us in Latin translations. The principal Latin writer on botany was Pliny the Elder (23–79 AD). From Mediaeval times, Latin became the universal scientific language (lingua franca) in Europe. Most written plant knowledge was the property of monks, particularly Benedictine, and the purpose of those early herbals was primarily medicinal rather than plant science per se. It would require the invention of the printing press (1450) to make such information more widely available.[1][2][3]

Leonhart Fuchs, a German physician and botanist is often considered the originator of Latin names for the rapidly increasing number of plants known to science. For instance he coined the name Digitalis in his De Historia Stirpium Commentarii Insignes (1542).

A key event was Linnaeus’ adoption of binomial names for plant species in his Species Plantarum (1753).[4]

In the nineteenth century it became increasingly clear that there was a need for rules to govern scientific nomenclature, and initiatives were taken to refine the body of laws initiated by Linnaeus. These were published in successively more sophisticated ions. For plants, key dates are 1867 (lois de Candolle) and 1906 (International Rules of Botanical Nomenclature, 'Vienna Rules'). The most recent is the Melbourne Code, adopted in 2011.[5]

Another development was the insight into the delimitation of the concept of 'plant'. Gradually more and more groups of organisms are being recognised as being independent of plants. Nevertheless, the formal names of most of these organisms are governed by the (ICN), even today. Some protists that do not fit easily into either plant or animal categories are treated under either or both of the ICN and the ICZN. A separate Code was adopted to govern the nomenclature of Bacteria, the International Code of Nomenclature of Bacteria.

Relationship to taxonomy[]

Botanical nomenclature is closely linked to plant taxonomy, and botanical nomenclature serves plant taxonomy, but nevertheless botanical nomenclature is separate from plant taxonomy. 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. "What plants belong to this species?" and "What species belong to this genus?". The definition of the limits of a taxon is called its 'circumscription'. For a particular taxon, if two taxonomists agree exactly on its circumscription, rank and position (i.e. the higher rank in which it is included) then there is only one name which can apply under the ICN.[6] Where they differ in opinion on any of these issues, one and the same plant may be placed in taxa with different names. As an example, consider Siehe's Glory-of-the-Snow, Chionodoxa siehei:

Flowers of Chionodoxa siehei, which can also be called Scilla siehei, or included in Chionodoxa forbesii or in Scilla forbesii

In summary, if a plant has different names or is placed in differently named taxa:
