Linnaeus' Species Plantarum (1753)

This is a list of terms and symbols used in scientific names for organisms, and in describing the names. For proper parts of the names themselves, see List of Latin and Greek words commonly used in systematic names. Note that many of the abbreviations are used with or without a stop.

Naming standards and taxonomic organizations and their codes and taxonomies

General terms

  • clade, cladistics
  • phylum, phylogeny
  • taxon, taxonomy; Taxon is a journal of the IAPT, where proposals are made
  • synonym: a name for a taxon different from the currently accepted name
    • pro parte (abbreviation p. p.; "for part" in Latin)
    • senior synonym, (zoology): the earliest (correctly published) name
    • junior synonym, (zoology): any later name
    • homotypic synonym (botany)
    • heterotypic synonym (botany): (or taxonomic synonym) a synonym that comes into being when a taxon is reduced in status ("reduced to synonymy") and becomes part of a different taxon; the zoological equivalent is "subjective synonym"
    • objective synonym (zoology)
    • subjective synonym (zoology): see taxonomic synonym
    • taxonomic synonym (botany): see taxonomic synonym
  • basionym or basyonym (botany), or protonym or original combination (zoology): original name on which the current name is based; in bacteriology "basonym"
  • combinatio nova (comb. nov.): new combination; when a taxon has been given a new name, preserving one of the previous components
  • status novus (abbr. stat. nov.): new status; when a taxon has been given a new rank
  • homonym: names spelled identically, but, in some codes, names spelled similarly, as defined by the code
    • senior homonym (zoology): the first legitimate use of the name which generally takes priority
    • junior homonym (zoology), later homonym (botany): a later and generally illegitimate use, though in some circumstances the later name is allowed to stand
    • hemihomonym: a homonym across naming authorities that is permitted because any confusion is improbable
    • parahomonym: names that are similar enough to be likely to be confused
  • isonym (botany) an identical name based on the same type, but published later
  • tautonym, a repeated name, for example Bubo bubo, Lutra lutra. Permitted in zoology, but not in botany.
  • Principle of the First Reviser
  • Principle of Priority
  • Principle of Typification
  • taxonomic authority
  • binomial authority
  • binomial nomenclature (also "binominal")
  • trinomial nomenclature (also "trinominal")
  • hybrid name (botany): either two parent binomials, separated by a "×" (q.v.) or a given binomial, with or without an intercalated "×"
  • chresonym published usage of a name.
  • taxon (plural "taxa")
  • polyphyletic taxon
  • monophyletic taxon: a taxon consisting of a common ancestor and all its lineal descendants; a clade
  • paraphyletic taxon
  • species complex: a group of closely related species very similar in appearance, generally constituting a monophyletic taxon
  • species aggregate or aggregate species: a grouping of closely related species that are treated like a single species for practical purposes
  • alliance: a group of species or genera that have at some time been considered provisionally related
  • conspecific: of the same species; e. g. of two taxa previously thought to be different species
  • congeners: items of the same genus
  • circumscription: the limits of a taxon as made evident by its recognized constituency; a taxon may accordingly be circumscribed differently by different authorities if they recognize different constituents
  • sensu ("sense" in Latin): as in sensu stricto (s. s.) (in the strict sense), sensu lato (in a broad sense), etc.; see sensu for more variants and details
  • secundum ("following" in Latin): e. g. "secundum Smith"

Types

Rank names

Main article: Taxonomic rank

The main ranks are kingdom (regnum), phylum or division (divisio), class (classis), order (ordo), family (familia), genus and species. The ranks of section and series are also used in botany for groups within genera, while section is used in zoology for a division of an order. Further levels in the hierarchy can be made by the addition of prefixes such as sub-, super-, infra-, and so on.

Divisions such as "morph", "form", "variety", "strain", "breed", "cultivar", hybrid (nothospecies) and "landrace" are used to describe various sub-specific groups in different fields.

It is possible for a clade to be unranked, for example Psoroptidia (Yunker, 1955) and the SAR supergroup. Sometimes a rank is described as clade where the traditional hierarchy cannot accommodate them.

Latin descriptions of names or taxa

Note that in zoology the English descriptions, such as "conserved name", for example, are acceptable and generally used. These descriptions can be classified between accepted names (nom. cons., nom. nov., nom. prot.) and unaccepted combinations for different reasons (nom. err., nom. illeg., nom. nud., nom. rej., nom. supp., nom. van.), with some cases in between regarding the use (nom. dub.: used but not fully accepted; nom. obl.: accepted but not fully used, so it yields precedence to a nom. prot).

  • Candidatus (Ca.) - a taxon proposed from incomplete information, such as uncultured bacteria known from metagenomics
  • ex errore – made in error
  • incertae sedis – of uncertain placement
  • nomen alternativum (nom. alt.; plural: nomina alternativa) – an alternative name, as for certain plant families
  • nomen conservandum (nom. cons.; plural: nomina conservanda) – a conserved name
  • nomen dubium (nom. dub.; plural: nomina dubia) (zoo. bact. bot.(informal)) – a name of questionable application[1]
    • nomen ambiguum (plural: nomina ambigua), (bot.) a name that has been used with more than one meaning
    • nomen confusum (plural: nomina confusa), (bact.) a name based on a mixed bacterial culture
    • nomen perplexum (plural: nomina perplexa), a name confusingly similar to another name or names
    • nomen periculosum (plural: nomina periculosa), an name which can lead to dangerous outcomes, through confusion
  • nomen erratum (nom. err.; plural: nomina errata) - a name given in error
  • nomen illegitimum (nom. illeg.; plural: nomina illegitima) – an illegitimate name
  • nomen invalidum (nom. inval.; plural: nomina invalida) – an invalid name
  • nomen manuscriptum - a name that appears in a manuscript
  • nomen monstrositatum (nom. monstr.) – a name based on a monstrosity (fasciation, phyllody or similar deformities)
  • nomen novum (nom. nov.; plural: nomina nova) – a replacement name
  • nomen nudum (nom. nud.; plural: nomina nuda) – a name published without an accompanying description
  • nomen oblitum (nom. obl.; plural: nomina oblita) – a name which has been overlooked (literally, forgotten) and is no longer valid
  • nomen protectum (nom. prot.; plural: nomina protecta) – a name granted protection
  • nomen rejiciendum (nom. rej.; plural: nomina rejicienda) – a name that has been rejected and cannot be used
  • nomen suppressum (nom. supp.; plural: nomina suppressa) – a name that has been suppressed and cannot be used
  • nomen vanum (plural: nomina vana) - not a useful term, has been used to mean either a nomen dubium (see above in this list), or an invalid change in spelling, better called an unjustified emendation[2]
  • nomina circumscribentia, a name derived from its circumscription
  • partim, indicates that a taxon was split and contains only a part of the original entity.[3]
  • species inquirenda, a species of doubtful identity requiring further investigation
