Genus ( / ˈdʒiːnəs / pl.: genera / ˈdʒɛnərə /) 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 biology, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system of biological classification ( taxonomy) consists of species, genus, family, order, class, phylum, kingdom, and domain. While older approaches to taxonomic classification were phenomenological, forming ...
The genus of a connected, orientable surface is an integer representing the maximum number of cuttings along non-intersecting closed simple curves without rendering the resultant manifold disconnected. [2] It is equal to the number of handles on it. Alternatively, it can be defined in terms of the Euler characteristic χ, via the relationship ...
Contents. List of plant genus names with etymologies (A–C) Since the first printing of Carl Linnaeus 's Species Plantarum in 1753, plants have been assigned one epithet or name for their species and one name for their genus, a grouping of related species. [ 1 ] Many of these plants are listed in Stearn's Dictionary of Plant Names for Gardeners.
Minor intermediate ranks are not shown. A species ( pl.: species) is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. [ 1] It is the basic unit of classification and a taxonomic rank of an organism, as well as a ...
An intensional definition gives meaning to a term by specifying necessary and sufficient conditions for when the term should be used. In the case of nouns, this is equivalent to specifying the properties that an object needs to have in order to be counted as a referent of the term. For example, an intensional definition of the word "bachelor ...
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.
t. e. In biology, taxonomy (from Ancient Greek τάξις ( taxis) 'arrangement' and -νομία ( -nomia) ' method ') is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a ...
