The plural is "genera". The second part is the species epithet. The entire name is written in italics. Our own species, for example, was given Homo sapiens it means "man who is wise". Linnaeus' system gives each species a unique identity. The system also fulfilled a second need of humans: the need to classify things.
Living things were first classified as plants or animals. Learn more about ISD and submit your research. Josh Lancette is manager of publications at the Entomological Society of America. Enter your email address to subscribe to Entomology Today. You'll receive notifications of new posts by email.

This naming system is used by scientists throughout the world. It was established by the great Swedish botanist and physician Carolus Linnaeus — He attempted to describe the entire known natural world and gave each distinct animal and plant at that time a two-part name.
The Genus and Species Concept. If the spelling of genus and species terms sounds like Greek to you. Every species can be unambiguously identified with just two words. The genus name and species name may come from any source whatsoever. Often they are Latin words, but they may also come from Ancient Greek, from a place, from a person, a name from a local language, etc. In fact, taxonomists come up with specific descriptors from a variety of sources, including inside-jokes and puns.
Scientific names sometimes bear the names of people who were instrumental in discovering or describing the species. Finally, some scientific names often reflect the common names given by people living in the region. Scientific names are treated grammatically as if they were a Latin phrase.
However, species names are commonly reused, and are usually an adjectival modifier to the genus name, which is a noun. So this was the initiation of a binomial system for plants Note: any name proposed for plants before this date is not accepted today.
Linnaeus proposed the scientific names of animals in his book Systema Naturae 10th edition. It was published on 1 August So initiation of a binomial system for animals is believed to have started then. According to this system, the name of a plant or animal is composed of two Latin or Latinised words.
They are derived from Latin irrespective of their origin. For example,. Each name has two components, the generic name , and the specific epithet. The first word indicates the name of the genus also called generic name. The second word denotes the name of the species also called specific epithet. The generic name always begins with a capital letter and the specific name with a small letter. The generic and specific names always have some meaning. They are based on some special characters of the plant and animals, or the name of any scientist or on some legend.
Usually, the name of the author , who names the organism, is also written in full or in abbreviated form after the specific name. The name of the scientist should be neither underlined nor in italics , but written in Roman letters simple alphabets. Thus, in the case of Mangifera indica L.
