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 (which may be shortened to just "binomial"), a binomen, binominal name or a scientific name; more informally it is also called a Latin name.
 The first part of the name identifies the genus to which the species belongs; the second part identifies the species within the genus.
 For example, humans belong to the genus "Homo" and within this genus to the species "Homo sapiens".
 The "formal" introduction of this system of naming species is credited to Carl Linnaeus, effectively beginning with his work "Species Plantarum" in 1753.
 But Gaspard Bauhin, in as early as 1623, had introduced in his book "Pinax theatri botanici" (English, "Illustrated exposition of plants") many names of genera that were later adopted by Linnaeus.
Apera is a small genus of annual grasses, known commonly as silkybent grass or windgrass.
 They are native to Europe, North Africa and parts of Asia but have been introduced and naturalized in much of North and South America.
United States Department of Agriculture Plants Profile
Platystemon is a monotypic genus of flowering plants in the poppy family containing the single species Platystemon californicus, which is known by the common name creamcups.
 It is native to Oregon, California, Arizona, Utah and Baja California, and is found in open grasslands and sandy soils.
Megalurus is a genus of passerine bird in the family Locustellidae.
 The genus was once placed in the Old World warbler "wastebin" family Sylviidae.
 The genus contains six species also known as the typical grassbirds.
 The genus is distributed from northern China and Japan, to India in the west, and Australia in the south, with most species being located wholly or partly in the tropics.
 The genus is also sometimes considered to include the genus "Bowdleria", which holds the fernbirds of New Zealand.
 The most widespread species, the tawny grassbird, ranges from the Philippines to southern New South Wales, whereas the Fly River grassbird is restricted to swampland in the southern part of New Guinea.
 The natural habitat of the typical grassbirds is, as the name suggests, wet grasslands, swamps and other marshlands.
 Some species exist away from water in tall grasslands, heathlands, and forest clearings.
 Some species have adapted to the margins of rice fields and gardens.
Apera spica-venti, the loose silky-bent or common windgrass, is an annual or biannual plant in the genus "Apera".
 It belongs to the Poaceae family.
Tokurites is monospecific genus of ammonite that lived during the Toarcian stage of early Jurassic, ammonite zone of Zugodactylites braunianus.
 Its shell has ribs, which are crossing ventral part of the shell and are creating pricky tubercules there.
 By these tubercules, it differs from any other member of Dactylioceratidae.
 This genus is closely related to genus "Reynesoceras".
 Genus is based on the single specimen with diameter of 15 mm and thus consist from only one species "Tokurites inopinatus".
 This only specimen has been found in asian part of Russia.
Palerontobia is a monotypic genus of tiger moths in the "Erebidae" family.
 The genus includes only one species, Palerontobia kozlovi, which is found in north-eastern Tibet (China, Qinghai).
 The scientific name consists of two parts, "Pale," is a part of the genus name "Palearctia", and "rontobia," is a part of the genus name "Orontobia".
 The species is named after Pyotr Kozlov, a disciple of Nikolay Przhevalsky, who first collected the Holotype in 1900.
Pitcairnia platystemon is a species in the genus "Pitcairnia".
 This species is endemic to Bolivia.
Nemegtomaia is a genus of oviraptorid dinosaur from what is now Mongolia that lived in the Late Cretaceous Period, about 70million years ago.
 The first specimen was found in 1996, and became the basis of the new genus and species N. barsboldi in 2004.
 The original genus name was "Nemegtia", but this was changed to "Nemegtomaia" in 2005, as the former name was preoccupied.
 The first part of the generic name refers to the Nemegt Basin, where the animal was found, and the second part means "good mother", in reference to the fact that oviraptorids are known to have brooded their eggs.
 The specific name honours the palaeontologist Rinchen Barsbold.
 Two more specimens were found in 2007, one of which was found on top of a nest with eggs, but the dinosaur had received its genus name before it was found associated with eggs.
Rhodostemonodaphne is a genus of flowering plants in the family Lauraceae.
 It is a neotropical genus consisting of approximately 41 species occurring in Central America and northern South America.
 This genus has many species that are valued for timber.
 The classification of the genus is unclear since the species in the genus fall into a well-supported but unresolved clade that also includes species with unisexual flowers currently placed in the genera "Endlicheria" and part of "Ocotea".
