Urasterella is an extinct genus of sea stars that lived from the Ordovician to the Devonian. [1] Its fossils are known from Europe, North America and southern Africa. [1]
There have been a number of species assigned or transferred to the genus since its description in 1851. [1]

Cimolodonta is a taxon of extinct mammals that lived from the Cretaceous to the Eocene. They were some of the more derived members of the extinct order Multituberculata. They probably lived something of a rodent-like existence until their ecological niche was assumed by true rodents. The more basal multituberculates are found in a different suborder, "Plagiaulacida".
Crassostrea is a genus of true oysters containing some of the most important oysters used for food. Some species in the genus have been moved to the genus Magallana.
Osmunda is a genus of primarily temperate-zone ferns of family Osmundaceae. Five to ten species have been listed for this genus.
Consolida is a genus of about 40 species of annual flowering plants in the family Ranunculaceae, native to western Europe, the Mediterranean and Asia. Phylogenetic studies show that Consolida is actually an annual clade nested within the genus Delphinium and it has been treated as a synonym of Delphinium in Kew's Plants of the World Online.
Fallopia is a genus of about 12 species of flowering plants in the buckwheat family, often included in a wider treatment of the related genus Polygonum in the past, and previously including Reynoutria. The genus is native to temperate and subtropical regions of the Northern Hemisphere, but species have been introduced elsewhere. The genus includes species forming vines and shrubs.
Parkinsonia, also Cercidium, is a genus of flowering plants in the pea family, Fabaceae. It contains about 12 species that are native to semi-desert regions of Africa and the Americas. The name of the genus honors English apothecary and botanist John Parkinson (1567–1650).
Niemeyera is a genus of plants in the family Sapotaceae described as a genus in 1870. The entire genus is endemic to Australia. Its closest relative is Pycnandra from New Caledonia.
The genus Securigera contains a number of plant species commonly referred to as crownvetch. It is a segregate of the genus Coronilla. The name Securigera was first published by A. P. de Candolle in 1805 with the single species Securigera coronilla, which is now considered to be a synonym of Securigera securidaca(L.) Degen & Dörfl. (1897), based on the earlier publication of the same taxon as Coronilla securidacaL. in 1753.
Coronella is a genus of harmless snakes in the family Colubridae. The genus is endemic to Europe, North Africa and West Asia. Three species are currently recognized as being valid.
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name to the Norway spruce, which he called Pinus abies. This name is no longer in use, so it is now a synonym of the current scientific name, Picea abies. In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination, rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refer to a taxon at that rank - for example, the name Papilio prorsaLinnaeus, 1758 is a junior synonym of Papilio levanaLinnaeus, 1758, being names for different seasonal forms of the species now referred to as Araschnia levana(Linnaeus, 1758), the map butterfly. However, Araschnia levana is not a synonym of Papilio levana in the taxonomic sense employed by the Zoological code.
Orthocarpus, or owl's-clover, is a genus of flowering plants in the family Orobanchaceae. They are native to North America. A number of species formerly included in Orthocarpus have been transferred to the genus Castilleja, which includes the plants commonly known as Indian paintbrush.
Zinnia elegans known as youth-and-age, common zinnia or elegant zinnia, is an annual flowering plant in the daisy family Asteraceae. It is native to Mexico but grown as an ornamental in many places and naturalised in several places, including scattered locations in South and Central America, the West Indies, the United States, Australia, and Italy.
The Betoideae are a small subfamily of the flowering plant amaranth family, Amaranthaceae sensu lato. Commonly known members include beet, sugar beet, chard, and mangelwurzel, which all are cultivars of Beta vulgaris.
Camphorosmeae is a species-rich tribe of the Amaranthaceae, formerly Chenopodiaceae, with 20 genera and about 179 species. It is classified as a single tribe of subfamily Camphorosmoideae.
Kali is a genus of plants in the subfamily Salsoloideae in the family Amaranthaceae. Common names of various members of this genus include tumbleweed for its wind-blown seed dispersal habit, and Tartar thistle and Russian thistle for its origins.

Stapelianthus is a genus of flowering plants in the family Apocynaceae, first described as a genus in 1933. The entire genus is endemic to Madagascar and is concentrated in the far south of the island.
Stapeliopsis is a genus of succulent plants in the family Apocynaceae, native to southern Africa.
