The definition may vary slightly depending on the source, the foundation of the discipline is in:
*the conception,
*the appointment,
*and the classifying groups of organisms, last phase that is associated with the systematic (science that aims to count and classify taxa in a certain order, based on different principles), which refers both to the method that the result obtained with this method.
The taxon is defined by its description.
His appointment and the publication of new taxa are governed by a set of rules, and in the disciplines of botany, phycology (study of algae) and mycology (study of fungi ), the appointment of taxa is governed by the International Code of Botanical Nomenclature.
In zoology, the regulation of nomenclature (greater family and subspecies) is done via the International Code of Zoological Nomenclature.
Zoology includes various specialized disciplines:
*the Entomology, the study of insects,
*the Herpetology, study of reptiles and amphibians,
*the Ichthyology, the study of fish,
*the Mammalogy, the study of mammals,
*the Ophiology, studying snakes,
*the Ornithology, the study of birds,
*the Malacology, the study of mollusks,
*the Arachnology, studying arachnids,
*the Carcinology, studying crustaceans,
*the Cetology, the study of cetaceans,
See: The Zoology

Inciale the description of a taxon includes five recommandations principales:
*the taxon must received a name whitch is composed from the 26 letters of the Latin alphabet(a pair of new species or uninominal for other patents).
*the name must be unique (without homonymous).
*the description must be based at least on a type of species.
*it should include references and attributes that become the single taxon.
*the first four recommendations should be published in a document subject to a large amount of identical copies, in the type register permanent cientific.

Often the information such as geographic distribution of taxon, notes on ecology, chemistry, behavior, etc ... are included.

International Association for Plant Taxonomy

The botanist and zoologist Carl Linnaeus, also a doctor in Sweden, is the one who developed the principles of Botanical Nomenclature and the classification of plants (1707 -1778).

The International Code of Nomenclature Botanical (ICBN) is a set of standards and guidelines that govern the allocation of formal way of binomial nomenclature for species in the area of botany and mycology.
The Code aims to certify that each taxonomic group or taxon of plants, algae, cianobacterias and fungus has a unique name, recognized and adopted worldwide. Each botanical name is linked to a "type species" (informal designation for the type of a name of one kind or another, is a specimen or illustration), almost always a plant herbarium or archived in a herbarium reference, in order to avoid any ambiguity and solve possible conflicts of identification.

Binomial nomenclature

In the natural sciences, the traditional classification is a method historically used to classify living things.
In the general sense, the following terms are synonyms of tradicional classification, systematic classic, traditional systematic, classical taxonomy, Linnaean classification, systematic and taxonomy Linnean.

Plant classification is organized into categories:
-Kingdom,
-Division,
-Class,
-Order,
-Family,
-Genus,
-specie like basic range.
The reign of plants consists of several Divisions,
each with multiple Classes,
each class with the same number of orders,
and so on successively and so on successively to the species (in inside which can meet subspecies, varieties and forms in the system).


The phylogenetic classification or classification APG (1998) or the APG II (2003) or the APG III (2009).
It is a system of classification of beings which aims to reflect the degree of relatedness between species and therefore helps to understand their evolutionary history (or phylogeny), except for certain groups like reptiles or fish.

*Changes wrought by the arrival of the Phylogenetic Classification

Plants belonging to the clade "eudicots" or "eudicot" are plants whose pollen grains contain three or more pores.
It includes as the following orders:
Apialesles, Aquifoliales, Asterales, Brassicales, Caryophyllales, Cornales, Cucurbitales, Dipsacales, Fabales, Fagales, Ericales, Garryales, Gentianales, Geraniales, Lamiales, Malpighiales, Malvales, Myrtales, Oxalidales, Proteales, Ranunculales, Rosales, Santalales, Sapindales, Saxifragales and the order of Solanales,

The following plants were classified (Cronquist classification) with broadleaf weeds but they have common features (including pollen grains in a pore) with monocots.
These are the Cératophyllales, the Laurales, the Magnoliales and the Piperales.
They are waiting, waiting to be solved with the evolution of the technologies used in this area.,

Monocots (or liliopsidas) include the following orders: Acorales, Alismatales, Liliales and Asparagales, Pandanales, Dioscoreales, Arecales, Poales, Commélinales and Zingiberales.
The monocotyledonous plants form an assembly which has been derived from plants Magnoliales..

The botanical name of a plant consists of 2 words,
*the first reference to the gender (sexe) belongs plant,
*and the second defines the plant within this genre,
but the plant is primarily identifies the species to which it belongs because of the characteristics identical to plants that easily distinguish them from others (for humans).
For this, we use technical language and cientific in the Latin language, with a correct mode for writing the botanical name implies it is written in italic style,
*The first word starts with a capital letter,
*and the second with a lowercase letter, and this whatever the country.
*A third word, often written in short, is that of the person who discovered the plant, or the first mentioned in written form.
