The differences between subspecies are usually less distinct than the differences between species. ... Names published before 1992 in the rank of variety are taken to ...
Variety is defined in the code as follows: "Variety (varietas) the category in the botanical nomenclatural hierarchy between species and form (forma)". The code acknowledges the other usage as follows: "term used in some national and international legislation for a clearly distinguishable taxon below the rank of species; generally, in ...
These differences arise because there are few available ranks and many branching points in the fossil record. Within species further units may be recognised. Animals may be classified into subspecies (for example, Homo sapiens sapiens , modern humans) or morphs (for example Corvus corax varius morpha leucophaeus , the pied raven).
Variety: This rank of taxa delineates differences between plants that are smaller than in subspecies but larger than forms. A variety retains most of the characteristics of the species, but differs in some way. Cultivar: Any variety produced by horticultural or agricultural techniques and not normally found in natural populations; a cultivated ...
He recognised the rank of varietas (botanical "variety", a rank below that of species and subspecies) and he indicated these varieties with letters of the Greek alphabet, such as α, β, and λ, before the varietal name, rather than using the abbreviation "var." as is the present convention. Most of the varieties that Linnaeus enumerated were ...
Differences between these two groups is attributed to phenotypic plasticity and are too few for them to be termed as wholly different species. [7] Emergence of variants of the same species may occur in the same geographical region where different habitats provide distinct ecological niches for these organisms examples of these habitats include ...
below that of variety (varietas) above that of form (forma). Subvariety is an infraspecific taxon. [1] Name. Its name consists of three parts: a genus name (genera)
In botany, an infraspecific name is the scientific name for any taxon below the rank of species, i.e. an infraspecific taxon or infraspecies.The scientific names of botanical taxa are regulated by the International Code of Nomenclature for algae, fungi, and plants (ICN). [1]
