Genus is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. 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.
In taxonomy, binomial nomenclature, also called binominal nomenclature or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name, a binomen, binominal name or a scientific name; more informally it is also called a Latin name.
The Crassulaceae, also known as the stonecrop family or the orpine family, are a diverse family of dicotyledon flowering plants characterized by succulent leaves and a unique form of photosynthesis, known as Crassulacean acid metabolism (CAM). Flowers generally have five floral parts. Crassulaceae are usually herbaceous but there are some subshrubs, and relatively few treelike or aquatic plants. Crassulaceae are a medium size monophyletic family in the core eudicots, among the order Saxifragales, whose diversity has made infrafamilial classification very difficult. The family includes approximately 1,400 species and 34–35 genera, depending on the circumscription of the genus Sedum, and distributed over three subfamilies. Members of the Crassulaceae are found worldwide, but mostly in the Northern Hemisphere and southern Africa, typically in dry and/or cold areas where water may be scarce, although a few are aquatic.
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon.
In zoological nomenclature, a type species is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). A similar concept is used for suprageneric groups and called a type genus.
Aeonium, the tree houseleeks, is a genus of about 35 species of succulent, subtropical plants of the family Crassulaceae. Many species are popular in horticulture. The genus name comes from the ancient Greek "αιώνιος"/"aionios" (ageless). While most of them are native to the Canary Islands, some are found in Madeira, Morocco, and in East Africa.
A botanical name is a formal scientific name conforming to the International Code of Nomenclature for algae, fungi, and plants (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the International Code of Nomenclature for Cultivated Plants (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae (Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups ."
In botany, an infraspecific name is the scientific name for any taxon below the rank of species, i.e. an infraspecific taxon. The scientific names of botanical taxa are regulated by the International Code of Nomenclature for algae, fungi, and plants (ICN). This specifies a 'three part name' for infraspecific taxa, plus a 'connecting term' to indicate the rank of the name. An example of such a name is Astrophytum myriostigma subvar. glabrum, the name of a subvariety of the species Astrophytum myriostigma.

Aizopsis is a genus of the succulent family Crassulaceae, found in E Asia.
Phedimus is a genus of the succulent family Crassulaceae, with about 18 species, distributed in eastern Europe and Asia. The genus is described with two subgenera, but one of these is also recognized as a separate genus, Aizopsis. Phedimus kamtschaticus is widely grown as an ornamental ground cover and has gained the Royal Horticultural Society's Award of Garden Merit.
Aizoon or Aizoön is a genus of flowering plants in the iceplant family, Aizoaceae.
Aizoanthemum hispanicum, or Spanish aizoon, is a species of plant in the family Aizoaceae. It is native to northern Africa, the Mediterranean region and the Middle East where it grows on arid sandy plains, saline areas and in semi-arid habitats. It was first described as Aizoon hispanicum by the Swedish naturalist Carl Linnaeus in 1753 and was in 2002 placed in the genus Aizoanthemum by the German botanist Heidrun Hartmann.
Gunniopsis is a genus of flowering plants in the iceplant family, Aizoaceae. These plants are found in areas of inland Australia.
Gunniopsis quadrifida, the Sturts pigface, is a plant endemic to Australia that is within the family Aizoaceae. This family consists of a diverse array of species that inhabit arid and/or saline coastal and inland areas, with the plants displaying leaf morphology that is conducive to such harsh environments. Typical features of members of this genus that lie within this family of succulents includes the presence of fleshy-leaves that acts as a water reservoir for the plant with the habit of a smalls shrub.
Gunniopsis calcarea, commonly known as the Nullarbor Gunniopsis or the yellow flowered pigface, is a succulent plant in the iceplant family, Aizoaceae. It is endemic to Australia.
Aizoon canariense is a species of small leafy annual plant in the family Aizoaceae.
Gustav August Ludwig David Schellenberg was a German botanist and newspaper publisher. He was born and died in Wiesbaden.
Chaloupkaea is a genus of flowering plants belonging to the family Crassulaceae.
Chromatomyia is a genus of flies belonging to the family Agromyzidae.
