The APG III system ( 2009 ) differs only in that the Limnocharitaceae are combined with the Alismataceae ; it was also suggested that the genus Maundia ( of the Juncaginaceae ) could be separated into a monogeneric family, Maundiaceae, but the authors noted that more study was necessary before Maundiaceae could be recognized.

The name is derived from the type genus Apium, which was originally used by Pliny the Elder circa 50 AD for a celery-like plant.

This fossil was originally described as a species of Australopithecus, but White and his colleagues later published a note in the same journal renaming the fossil under a new genus, Ardipithecus.

The type species, A. sarcophagus, was apparently restricted in range to the modern-day Canadian province of Alberta, after which the genus is named.

For many years there was confusion amongst botanists over the generic names Amaryllis and Hippeastrum, one result of which is that the common name " amaryllis " is mainly used for cultivars of the genus Hippeastrum, widely sold in the winter months for their ability to bloom indoors.

However, the tree constructed by the living tree project, a collaboration between ARB-Silva and LPSN where a 16S ( and 23S if available ) tree of all validated species was constructed, the genus Bacillus contains a very large number of nested taxa and majorly in both 16S and 23S it is paraphyletic to Lactobacillales ( Lactobacillus, Streptococcus, Staphylococcus, Listeria, etc.

The species name troglodytes, Greek for " cave-dweller ", was coined by Johann Friedrich Blumenbach in his book De generis humani varietate nativa liber (" on the natural varieties of the human genus ") published in 1776, This book was based on his dissertation presented one year before ( it had a date 16 Sep 1775 printed on its title page ) to the University of Göttingen for internal use only, thus the dissertation did not meet the conditions for published work in the sense of zoological nomenclature.

This genus was traditionally placed in the figwort family Scrophulariaceae, but recent reviews of phylogenetic research have placed it in the much enlarged family Plantaginaceae.

Dsungaripterus was a genus of pterosaur, with an average wingspan of.

The genus Entamoeba was defined by Casagrandi and Barbagallo for the species Entamoeba coli, which is known to be a commensal organism.

For a time during the first half of the 20th century the entire genus Entamoeba was transferred to Endamoeba, a genus of amoebas infecting invertebrates about which little is known.

It was considered to be the first species of the genus Homo until May 2010, when a new species, Homo gautengensis was discovered in South Africa, that most likely arose earlier than Homo habilis.

He used a two-part naming scheme where the first name represented the genus and the second the species.

When writing the scientific name of an organism, it is proper to capitalize the first letter in the genus and put all of the specific epithet in lowercase.

Most of the kinds commonly eaten fresh or dried, those of the genus Phaseolus, come originally from the Americas, being first seen by a European when Christopher Columbus, during his exploration, of what may have been the Bahamas, found them growing in fields.

*** Canis ( Eucyon ) cipio ( 8. 2 Ma †, probably first species of Canis genus )

The gibbons ( hylobatidae ) and orangutans ( genus Pongo ) were the first groups to split from the line leading to the humans, then gorillas followed by the chimpanzees and bonobos.

Molecular evidence suggests that between 8 and 4 million years ago, first the gorillas, and then the chimpanzees ( genus Pan ) split off from the line leading to the humans ; human DNA is approximately 98. 4 % identical to that of chimpanzees when comparing single nucleotide polymorphisms ( see human evolutionary genetics ).

The first component of its taxonomic designation, Panthera, is Latin, from the Greek word for leopard, πάνθηρ, the type species for the genus.

The name is based on the genus Polygonum and was first used by Antoine Laurent de Jussieu in 1789 in his book, Genera Plantarum.

The first reptiles had an anapsid type of skull roof, as seen in the Permian genus Captorhinus

However, this is not the first species of homininae: the first species of genus Homo, Homo habilis, are theorized to have evolved in East Africa at least 2 million years ago, and members of this species populated different parts of Africa in a relatively short time.

This genus is of great interest since it contains thale cress ( Arabidopsis thaliana ), one of the model organisms used for studying plant biology and the first plant to have its entire genome sequenced.

The Cannabis genus was first classified using the " modern " system of taxonomic nomenclature by Carolus Linnaeus in 1753, who devised the system still in use for the naming of species.

He considered the genus to be monotypic, having just a single species that he named Cannabis sativa L. ( L. stands for Linnaeus, and indicates the authority who first named the species ).

The Banksia genus was first described and named by Carolus Linnaeus the Younger in his April 1782 publication Supplementum Plantarum ; hence the full name for the genus is " Banksia L. f ." The genus name honours the English botanist Sir Joseph Banks, who collected the first Banksia specimens in 1770, during James Cook's first expedition.

It was described as a new genus and species by Robert Broom of the Transvaal Museum.

Shaw assigned it as a Linnaean genus name when he initially described it, but the term was quickly discovered to belong already to the wood-boring ambrosia beetle ( genus Platypus ).

This was supported by the description of an additional pterosaur egg belonging to the genus Darwinopterus, described in 2011, which also had a leathery shell and, also like modern reptiles but unlike birds, was fairly small compared to the size of the mother.

Male Pteranodon sternbergi, the older species of the two described to date ( and sometimes placed in the distinct genus Geosternbergia ), had a more vertical crest with a broad forward projection, while their descendants, Pteranodon longiceps, evolved a narrower, more backward-projecting crest.

French zoologist Frédéric Cuvier initially described the red panda in 1825, and classified it as a close relative of the raccoon ( Procyonidae ), though he gave it the genus name Ailurus, " cat ", based on superficial similarities with domestic cats.

There are 600 described species of this single genus.

The genus contains at least 68 described extant taxa, but the true number of species is a matter of debate.

The fossil was subsequently described as Plesiosaurus dolichodeirus and is the type specimen ( holotype ) of the species, which itself is the type species of the genus.

They were originally described by Walcott as separate fossils under the genus name Helenia, ( Walcott's wife was named Helena and his daughter Helen ); Runnegar adopted the name helen when they were recognized as part of the hyolith organism.

The best-known is the type genus Peripatus, which was described as early as 1825 and which, in English-speaking countries, stands representative for all velvet worms.

In the taxonomical structure " genus → species ", a species is described as sui generis if its genus was created to classify it ( i. e. its exceptional uniqueness at the time of classification necessitated the creation of a new genus, the sole member of which was initially the sui generis species ).

The origin of the name is uncertain, but it could be a corruption of'm ' oganwo ', the name used by the Yoruba and Ibo people of West Africa to described trees of the genus Khaya, which is closely related to Swietenia.
