An interpolated name is italicized and placed in non-italic parentheses (round brackets); some examples are after a genus name to indicate a subgenus, after a genus group to denote an aggregate of species, after a species name to mean an aggregate of subspecies, after a genus and the word "section" or "sect." to provide a botanical genus ...
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. For example, the zoological name for the human species is Homo sapiens. This is usually italicized in print or underlined ...
Virus taxonomy is a partial exception; current scientific practice is to italicize all ranks of taxa (even those higher than genus; e.g., Ortervirales, an order, or Herpesviridae, a family). However, this should only be done in articles about viruses or virology; mentions of virus taxa in articles about other forms of life should follow the ...
Authors may also use "spp." as a short way of saying that something applies to many species within a genus, but not to all. If scientists mean that something applies to all species within a genus, they use the genus name without the specific name or epithet. The names of genera and species are usually printed in italics. However, abbreviations ...
No indicator of rank is included: in zoology, subspecies is the only rank below that of species. For example: "Buteo jamaicensis borealis is one of the subspecies of the red-tailed hawk (Buteo jamaicensis)." In a taxonomic publication, a name is incomplete without an author citation and publication details. This indicates who published the name ...
In a classification system based on ranks, there are also ways of naming ranks above the level of genus and below the level of species. Ranks above genus (e.g., family, order, class) receive one-part names, which are conventionally not written in italics. Thus, the house sparrow, Passer domesticus, belongs to the family Passeridae. Family names ...
For instance, we talk about the genus Homo, the species Homo sapiens, and the subspecies Homo sapiens sapiens. In botany, it is important to include the rank for taxa below species. The rank is not italicized, e.g. Genus species subsp. subspecies var. variety. Some bacteria that have been characterized but not formally named are given ...
The hierarchy of biological classification's eight major taxonomic ranks.Intermediate minor rankings are not shown. Forma specialis (plural: formae speciales), abbreviated f. sp. (plural ff. spp.) without italics, is an informal taxonomic grouping allowed by the International Code of Nomenclature for algae, fungi, and plants, [1] that is applied to a parasite (most frequently a fungus) which ...
