Type specimens and circumscription

The botanical name itself is fixed by a type, which is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name is formally attached. In other words, a type is an example that serves to anchor or centralize the defining features of that particular taxon. The usefulness of botanical names is limited by the fact that taxonomic groups are not fixed in size; a taxon may have a varying
circumscription Circumscription may refer to: *Circumscribed circle * Circumscription (logic) *Circumscription (taxonomy) *Circumscription theory, a theory about the origins of the political state in the history of human evolution proposed by the American anthrop ...

, thus, the group that a particular botanical name refers to can be quite small according to some people and quite big according to others. For example, the traditional view of the family

Components of plant names

A botanical name in three parts, i.e., an
infraspecific name In botany, an infraspecific name is the scientific name for any taxon below the rank of species, i.e. an infraspecific taxon or infraspecies. (A "taxon", plural "taxa", is a group of organisms to be given a particular name.) The scientific names ...
(a name for a taxon below the rank of species) needs a "connecting term" to indicate rank. In the ''Calystegia'' example above, this is "subsp.", for subspecies. In botany there are many ranks below that of species (in zoology there is only one such rank, subspecies, so that this "connecting term" is not used in zoology). A name of a "subdivision of a genus" also needs a connecting term (in the ''Acacia'' example above, this is "subg.", subgenus). The connecting term is not part of the name itself. A taxon may be indicated by a listing in more than three parts: "''Saxifraga aizoon'' var. ''aizoon'' subvar. ''brevifolia'' f. ''multicaulis'' subf. ''surculosa'' Engl. & Irmsch." but this is a classification, not a formal botanical name. The botanical name is ''Saxifraga aizoon'' subf. ''surculosa'' Engl. & Irmsch. (''ICN'' Art 24: Ex 1). Generic, specific, and infraspecific botanical names are usually printed in
italics In typography, italic type is a cursive font based on a stylised form of calligraphic handwriting. Owing to the influence from calligraphy, italics normally slant slightly to the right. Italics are a way to emphasise key points in a printed ...
. The example set by the ''ICN'' is to italicize all botanical names, including those above genus, though the ''ICN'' preface states: "The ''Code'' sets no binding standard in this respect, as typography is a matter of editorial style and tradition not of nomenclature". Most peer-reviewed scientific botanical publications do not italicize names above the rank of genus, and non-botanical scientific publications do not, which is in keeping with two of the three other kinds of scientific name:
zoological Zoology ()The pronunciation of zoology as is usually regarded as nonstandard, though it is not uncommon. is the branch of biology that studies the animal kingdom, including the structure, embryology, evolution, classification, habits, and dis ...

( viral names above genus are italicized, a new policy adopted in the early 1990s).


Binary name

For botanical nomenclature, the ''ICN'' prescribes a two-part name or binary name for any taxon below the
rank Rank is the relative position, value, worth, complexity, power, importance, authority, level, etc. of a person or object within a ranking, such as: Level or position in a hierarchical organization * Academic rank * Diplomatic rank * Hierarchy * ...
of genus down to, and including, the rank of species. Taxa below the rank of species get a three part (
infraspecific name In botany, an infraspecific name is the scientific name for any taxon below the rank of species, i.e. an infraspecific taxon or infraspecies. (A "taxon", plural "taxa", is a group of organisms to be given a particular name.) The scientific names ...
). A binary name consists of the name of a
genus Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus com ...
and an epithet. * In the case of a species this is a specific epithet: :''
Bellis perennis ''Bellis perennis'' (), the daisy, is a European species of the family Asteraceae, often considered the archetypal species of the name daisy. To distinguish this species from other plants known as daisies, it is sometimes qualified as common dais ...
'' is the name of a species, in which ''perennis'' is the specific epithet. There is no connecting term involved to indicate the rank. * In the case of a subdivision of a genus (subgenus, section, subsection, series, subseries, etc.) the name consists of the name of a genus and a subdivisional epithet. A connecting term should be placed before the subdivisional epithet to indicate the rank: :''Paraserianthes'' sect. ''Falcataria''


In cultivated plants

In the case of cultivated plants, there is an additional epithet which is an often non-Latin part, not written in italics. For cultivars, it is always given in single quotation marks. The cultivar, Group, or grex epithet may follow either the botanical name of the species, or the name of the genus only, or the unambiguous common name of the genus or species. The generic name, followed by a cultivar name, is often used when the parentage of a particular hybrid cultivar is not relevant in the context, or is uncertain.
