A Variety is a plant that is only slightly different from the species plant, but the differences are not so insignificant as the differences in a form. The Latin is varietas, which is usually abbreviated to var. The name follows the Genus and species name, with var. before the individual variety name.ogether, the Genus and species name refer to only one plant, and they are used to identify that particular plant.
The first word always identifies the genus to which the organism belongs and is capitalized. The second word designates the species or trivial name and is not capitalized. Both names are underlined separately, e.g. Many types of evidence are used in the development of a classification system. They may include biochemical, structural (morphological), cytological, physiological, or ecological evidence. VARIETY A Variety is a plant that is only slightly different from the species plant, but the differences are not so insignificant as the differences in a form. The Latin is varietas, which is usually abbreviated to var. The name follows the Genus and species name, with var. before the individual variety name. Together, the Genus and species name refer to only one plant, and they are used to identify that particular plant. Sometimes, the species is further divided into sub-species that contain plants not quite so distinct that they are classified as Varieties. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. The number of species in genera varies considerably among taxonomic groups. For instance, among (non-avian) reptiles However, some insect genera such as the bee genera Lasioglossum and Andrena have over 1000 species each. Which species are assigned to a genus is somewhat arbitrary. Usually, only the Family, Genus and species are of concern to the gardener, but we sometimes include subspecies, variety or cultivar to identify a particular plant. Starting from the top, the highest category, plants have traditionally been classified as follows. Together, the Genus and species name refer to only one plant, and they are used to identify that particular plant. Sometimes, the species is further divided into sub-species that contain plants not quite so distinct that they are classified as Varieties. Genus and Species. The taxonomic divisions beyond the family level are the genus and specific epithet names, together called the species. Plants are named using a binomial system. The genus name comes first and is analogous to a person’s last name (like Smith). Variety or Subspecies is a sub-grouping of species assigned to individuals displaying unique differences in natural populations. The differences are inheritable and reproduce true-to-type in each generation. For example cauliflower and cabbage are varieties of the same species Brassica oleracea. There are hierarchical levels of classification (ranks) above and below the genus and species, the most commonly referred to is the grouping of several genera (plural of genus) into a family. As with plants within the same genus, plants in the same family have many characteristics in common. Scientific names. At the simplest level of scientific classification, each plant has a name made up of two parts, a generic (or genus) name and a specific name or epithet. Together, these two names are referred to as a binomial. 1 The second name corresponds to a specific name identifying that type of organism as a unique group (species) from other members of its genus (i.e. H. sapiens vs. H. erectus). 2  The species name is not capitalized. 3  When naming your hardware, name put the genera name first and the species name second. Species was Linnaeus’s least inclusive level of classification and includes all organisms of similar morphologies that can interbreed and produce viable offspring. Given the vast scope of his work, Linnaeus completely ignored classifying single-celled organisms. A form is a plant within a species that has minor botanical differences, such as the colour of flower or shape of the leaves. The name follows the Genus and species name, with form (or f.) before the individual variety name. Together, the Genus and species name refer to only one plant, and they are used to identify that particular plant. Sometimes, the species is further divided into sub-species that contain plants not quite so distinct that they are classified as Varieties. The highest rank (most inclusive) was given to kingdom, followed subsequently by phylum, class, order, family, genus, and species. Species was Linnaeus’s least inclusive level of classification and includes all organisms of similar morphologies that can interbreed and produce viable offspring. Given the vast scope of his work, Linnaeus completely ignored classifying single-celled organisms.
