Classification is the practice of grouping things into useful categories based on plainly observable characteristics. As a result, all living species can be divided into different taxa based on their properties. Taxonomy is the term for this classifying procedure. The external and internal structure of organisms, as well as cell structure, development process, and ecological information, are essential and form the basis of modern taxonomic investigations. 

As a result, the processes of characterisation, identification, categorization, and naming serve as the foundation for taxonomy.Tha main objectives of plant taxonomy is to identify characteristics of undiscovered species by comparing with known species, to specify characteristics of recently discovered species, to arrange them in respective ‘taxa’ after looking at their similarities and to give them scientific names. Plant taxonomy plays very crucial role in the nomenclature of plants.

What is plant taxonomy

Plant taxonomy is the science of discovering, identifying, describing, classifying, and naming plants. It is one of the most important branches of taxonomy (the science that finds, describes, classifies, and names living things).

Plant systematics and taxonomy are inextricably linked. there are no clear distinction between the two. In practice, “plant systematics” is concerned with relationships between plants and their evolution, particularly at higher levels, whereas “plant taxonomy” is concerned with the actual handling of plant specimens. However, the precise relationship between taxonomy and systematics has evolved along with the goals and methods used.

Plant systematics and taxonomy are inextricably linked. with little agreement on taxonomic circumscription and placement. See the list of plant taxonomy systems.

System of plant taxonomy list

The first classification system took only a few vegetative characteristics into account. Modern taxonomic studies are more detailed and take into account various morphological, cellular, and molecular characteristics, such as cellular and reproductive features, mode of nutrition, habitat, evolutionary relationships, and so on, in addition to morphological features.

There are three main types of plant classification systems. Here is a list of plant taxonomy systems:

Classification system created artificially

Natural Classification System

Classification system based on phylogeny.

• 1. Artificial systems: The earliest systems attempted to classify organisms based on a few superficial characteristics.
• 2. Natural systems: In this classification system, more characters were taken into account when classifying. It was based on the organisms’ natural similarities in vegetative and floral characteristics. It considered various external and internal features such as cell anatomy, embryo types, and phytochemistry.
• 3. The Phylogenetic Classification System: This classification system is based on evolutionary sequence and genetic relationship. Following the publication of Darwin’s theory of evolution, the phylogenetic system of classification was developed. Aside from the morphological characteristics discovered in fossil records, genetic constituents were also taken into account.

Importance of plant taxonomy

• provides a detailed overview of a plant species’ various morphological and anatomical structures.
• It arranges all of the information about plants in a logical order.
• It denotes the phylogenetic relationship of a species to its ancestors.
• Plant taxonomy allows for the identification of unknown species and their classification by comparing them to known species.
• The systematics method can be used to analyse genetic constituents.
• It is used to scientifically name any species, which aids in name consistency around the world and prevents confusion.

• It aids in understanding the biodiversity of a location.
• It aids in the documentation of all known living species.
• Agriculture, medicine, and forestry all make extensive use of taxonomy.

Classification of plant taxonomy

• Plant taxonomy, also known as classification, is the science of naming organisms and classifying them into hierarchical groups, with each level given a name (kingdom, division (phylum), class, order, family, genus, species).

• Taxa are taxonomic units at a given level (singular taxon). Uninominal names are used for higher order taxa (kingdom, phylum, class, order, family, and genus) (each name is a single word). 

• Species names are binomial (Magnolia virginiana), and names of taxa below the rank of species ( subspecies, varieties) are made up of three or more words (Panicum virgatum var. cubense). Any given organism can be classified at any level of the hierarchy.

• Sweet bay magnolia (Magnolia virginiana), for example, belongs to the genus Magnolia, the family Magnoliaceae, the order Magnoliales, the class Magnoliopsida, the division Magnoliophyta, and the kingdom Plantae.

• Arranging scientific plant names in a hierarchical classification allows related organisms (all true pines are in the genus Pinus) to be classified close together, which aids in information retrieval.
