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.
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".

The set of rules and recommendations for formal botanical nomenclature, including plants, is governed by the International Code of Nomenclature for algae, fungi, and plants abbreviated as ICN. Plant description is a formal description of a newly discovered species, usually in the form of a scientific paper using ICN guidelines.
A sign for Crassula rupestris at the University of Helsinki Botanical Garden. The roots for the binomial name are crassus (thick, fat) and rupestris (living on cliffs or rocks) This list of Latin and Greek words commonly used in systematic names is intended to help those unfamiliar with classical languages to understand and remember the ...
Secondly it must be a system, i.e. deal with the relationships of plants. Although thinking about relationships of plants had started much earlier (see history of plant systematics), such systems really only came into being in the 19th century, as a result of an ever-increasing influx from all over the world of newly discovered plant species ...
A distinction can be made between botanical science in a pure sense, as the study of plants themselves, and botany as applied science, which studies the human use of plants. Early natural history divided pure botany into three main streams morphology - classification , anatomy and physiology – that is, external form, internal structure, and ...
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 (ICBN) and the earlier International Rules of Botanical Nomenclature.
The key activities of cultivated plant taxonomy relate to classification and naming (nomenclature).The rules associated with naming plants are separate from the methods, principles or purposes of classification, except that the units of classification, the taxa, are placed in a nested hierarchy of ranks – like species within genera, and genera within families.
