The format for writing clinical names the animals and also plants is standardized and also internationally accepted. “Scientific nomenclature” refers to miscellaneous names follow to a particular field that study. This post is the first in a series on scientific nomenclature within details kingdoms.

Usually, pets & tree are figured out by common and scientific names.

Common name: these are supplied locally and may vary by region or country.

Scientific name: these are unique names used by the scientific ar to accurately and also universally recognize species.

International codes of Nomenclature

Taxonomists have established several “codes” for scientific nomenclature. These codes are universal and are periodically update by consensus. The protocol for naming species was designed in the 1700s by swedish botanist Carl Linnaeus. Linnaeus created the mechanism of “binomial nomenclature,” which supplies only 2 designationsgenus and specific epithet together the varieties name.

In the mid-1800s, researchers agreed on an increased system the nomenclature. The complying with codes are used today:

Common names of varieties can differ by geographic an ar but a universal protocol helps prevent ambiguity and also ensures consistency.


Known together the “taxonomic hierarchy,” the system is composed of several teams of varieties based on genetic and also phylogenic characteristics. The greatest level is the “kingdom.” The an initial kingdom comprised only two varieties of life organisms—animals and also plants. We have seven classifications in ~ the kingdom domain—Bacteria, Archaea, Protozoa, Chromista, Plantae, Fungi, and also Animalia.

Note that the designations are in Latin. This might be challenging for some who are not acquainted with that language; however, the state are globally consistent. There is no require to translate them or translate them into one more language.

The level from highest to lowest category are together follows:


Using this system, the gray wolf, for example, would be identified as follows:

Domain: Eukarya.Kingdom: Animalia.Phylum: Chordata.Class: Mammalia.Order: Carnivora.Suborder: Caniformia.Family: Canidae.Genus: Canis.Species: lupus.

Binomial Name

The binomial name is composed of a genus surname and specific epithet. The clinical names of varieties are italicized. The genus surname is constantly capitalized and also is composed first; the specific epithet follows the genus name and is no capitalized. There is no exemption to this.

From over example, note that the classifications go from general (Animalia) to details (C. Lupus). A species, by definition, is the combination of both the genus and particular epithet, not just the epithet. Because that example, we can use the term gray wolf but we can not use simply Canis or lupus to describe this animal. Canis lupus is a species.

Writing scientific Names of Animals

When writing, we use both the clinical name and the “common” name on the first mention. We then choose which to usage throughout and make the consistent.

Gray wolf (Canis lupus) is aboriginal to phibìc America and also Eurasia.

In succeeding references, we deserve to use either the typical or scientific name. If we use the clinical name, we need only to use the an initial letter that the genus followed by a duration and the particular epithet. For example:

In phibìc America, the gray wolf was virtually hunted come extinction.In north America, C. Lupus was nearly hunted come extinction.

It is also common to refer to several varieties under one genus as soon as you desire to allude out some similar characteristics in ~ a genus. For example:

All species of Canis are known to be moderate to huge and have huge skulls.

You could likewise write this same info another way as follows:

Canis spp. are known to be moderate to huge and have large skulls.

In this case, “spp.” is an abbreviation for “several species” (“sp” is the designation for one species) in the genus. Either of the above is acceptable. If girlfriend are focusing on a few species in particular, you would describe the species name of each one.

You might additionally see a scientific name followed by one initial or abbreviation. This would denote the person who found or called the species. Because that example, in Amaranthus retroflexus L., the l (not italicized) refers to the original name offered by Linnaeus.


There are a couple of exceptions to several of these rules. First, the entire genus name must be spelled out if it begins a sentence, also if a succeeding reference:

Canis lupus was nearly hunted come extinction in north America.

Second, when more than one varieties has the exact same genus initial yet come from different genera, the genera names room spelled the end to stop confusion:

Both the gray wolf (Canis lupus) and the beaver (Castor canadensis) are indigenous to phibìc America.

In this case, the is ideal to usage the typical name ~ the very first mention, yet either style is correct.

Titles and also Headers

In titles, that is proper to write the whole scientific name of pets in uppercase letters. Because that example:

A study of the background of CANIS LUPUS in north America

In one italicized header, the varieties name have the right to be written in non-italic style. Because that example:

Canis lupus is nearly extinction in phibìc America

Writing clinical Names that Plants

Plant names additionally follow binomial nomenclature (similar to animal names).

Royal grevillea (Grevillea victoriae) is found in new South Wales and Victoria.

In the plant kingdom, category after types is subspecies (subsp.) and range (var.). For example, there are three subspecies the Grevillea victoriae.

 Grevillea victoriae subsp. victoriaeGrevillea victoriae subsp. nivalis Grevillea victoriae subsp. brindabella

When the varieties of a plant is unknown, a plant have the right to be referred together Grevillea sp.

Moreover, once we collectively want come refer few or every species, we usage Grevillea spp.

Similar to animal names, the is typical to see a specific epithet that refers to a geographical area or the human who found it. For example, Grevillea victoriae F.Muell. Although this are proper nouns, they are still written in small letter font. Be responsibility that some word processors could attempt come capitalize these references.

This is something to inspect when proofreading your text.

Cultivar names are dictated by global Code of Nomenclature for grew Plants

When writing, the cultivar name is added after genus or details epithet and is placed in solitary quotes without italicization. Because that example,  

 Grevillea ‘Robyn Gordon’   Grevillea rosmarinifolia ‘Rosy Posy’


One that the straightforward rules of scientific writing is consistency. Regardless of your selection of scientific or common name, girlfriend must preserve consistency. Constantly check the writer guidelines once preparing manuscripts. Styles for citations and references, headings, and also section placement can be different. It is in assured the the layout for writing scientific names is internationally consistent regardless of the plan journal. The rules presented above will help.
