A taxon is usually assigned a rank when it is given its formal name. The basic ranks are species and genus. When an organism is given a species name it is assigned to a genus, and the genus name is part of the species name. The species name is also called a binomial, that is, a two-term name.
Genus (/ ˈ dʒ iː n ə s /; pl.: genera / ˈ dʒ ɛ n ər ə /) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses. [1] In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.
In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name with that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such ...
The scientific name of a species is a binomial or binomen, and comprises two Latin words, the first denoting the genus and the second denoting the species. [5] The scientific name of a subspecies is formed slightly differently in the different nomenclature codes.
Division is a taxonomic rank in biological classification that is used differently in zoology and in botany.. In botany and mycology, division is the traditional name for a rank now considered equivalent to phylum.
The hierarchy of biological classification's eight major taxonomic ranks. A genus contains one or more species. Minor intermediate ranks are not shown. A species (pl.: species) is a population of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. [1]
The principal ranks in modern use are domain, kingdom, phylum (division is sometimes used in botany in place of phylum), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms ...
The genus was established by Carl Linnaeus in 1753. [6] Its subdivision has always been problematic, but slowly some sort of consensus is being achieved. [citation needed] The following list is a provisional lineup of the genus' traditional subdivisions, together with some notable species. [6]
