List of Systems in Plant Taxonomy

Only a few vegetative features were taken into consideration by the first categorization scheme. In addition to physical aspects, more complex modern taxonomic investigations have taken into account a variety of morphological, cellular, and molecular factors, such as cellular and reproductive features, method of feeding, habitat, evolutionary connections, etc. Main system on which classification of plant system has been divised

Artifical System

• This was based on the most basic characteristics, such as habit and the quantity and arrangement of sexual units.
• It is dominating from the year 300 BC and considerd to be the old method.
• This approach, which often uses one or a few characters to aid in identifying.

Natural System

• It was proposed by Linnaeus and was based on floral characteristics and cotyledon numbers.
• It considered a number of internal and exterior characteristics, including phytochemistry, different kinds of embryos, and cell architecture.
• The most significant natural system of categorization for flowering plants was the Bentham and Hooker system.

Phylogentic System

• It was developed after Darwin’s theory.
• Phylogenetic system was based on genetic relationship and evolution.
• There are two main phylogenetic system, (1) Enger and Prantl system (2) John hutchinson system classification.

Angiosperm Phylogeny Group (APG) System

It was most moderna and molecular based plant taxonomy system classification and are updated three time

• APG II publishedin 2003 and replaced original APG classification
• APG III published in 2009 and replaced APG II clssification
• APG IV published in 2016 and replaced APG III classification

Bessey System Classificaion

It was published by Charles Bessey in 1915.

• Cronquist system: This system classification by published by Arthur Cronquist in 1968 and was based on flowering plants.
• Melchior System: It is also known as Engler or modern sytem classification and consist of taxonomic classification of Angiospermae.

Plant taxonomy is the branch of science that deals with plant identification, name, classification, and description. Plant taxonomy is associated with plant systematics. Plant systematics is the study that evaluates the relationship between plants and their evolution at higher levels while plant taxonomy deals with handling specimens whether it is known or unknown species.
