The abbreviation "sp." is used when the actual specific name cannot or need not be specified. The abbreviation "spp." (plural) indicates "several species". These abbreviations are not italicised (or underlined).
The abbreviation for species is sp. (plural spp.) and is used after a generic epithet to indicate a species of that genus. Often used to denote a strain of a genus for which the species is not known either because the organism has not been described yet as a species or insufficient tests were conducted to identify it.
The starting point, that is the time from which these codes are in effect (usually retroactively), varies from group to group, and sometimes from rank to rank. [7] In botany and mycology, the starting point is often 1 May 1753 (Linnaeus, Species plantarum). In zoology, it is 1 January 1758 (Linnaeus, Systema Naturae, 10th Edition).
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.
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.
Among cultivated plants, seedlings, crosses [métis] of uncertain origin and sports, receive fancy names in common language, as distinct as possible from the Latin names of species or varieties. When they can be traced back to a botanical species, subspecies or variety, this is indicated by a sequence of names (Pelargonium zonale Mistress-Pollock).
The collective term for a natural grouping of species, domesticated type of organism, or range of breeds or varieties, is always written in lower case (except where a proper name occurs): New World monkeys, slime mold, rove beetles, great apes, mountain dogs, a spitz-type dog breed, hound group, long-haired breed group section, triticale, blood ...
A subspecies is a taxonomic rank below species – the only such rank recognized in the zoological code, [14] and one of three main ranks below species in the botanical code. [12] When geographically separate populations of a species exhibit recognizable phenotypic differences, biologists may identify these as separate subspecies; a subspecies ...
