Once a plant specimen has been identified, its name and properties are known. Plant classification is the placing of known plants into groups or categories to show some relationship. Scientific classification follows a system of rules that standardizes the results, and groups successive categories into a hierarchy.
A pioneering system of plant taxonomy, Linnaeus's Systema Naturae, Leiden, 1735. This list of systems of plant taxonomy presents "taxonomic systems" used in plant classification. A taxonomic system is a coherent whole of taxonomic judgments on circumscription and placement of the considered taxa. It is only a "system" if it is applied to a ...
However, in 1737 he published Genera Plantarum in which he claimed that his classification of genera was a natural system. [3] His botanical classification and sexual system were used well into the nineteenth century. [4] Within each class were several orders. This system is based on the number and arrangement of male and female organs. [5]
Evolution of angiosperms shown in diagram format, per APG IV. The APG IV system of flowering plant classification is the fourth version of a modern, mostly molecular-based, system of plant taxonomy for flowering plants (angiosperms) being developed by the Angiosperm Phylogeny Group (APG).
The Raunkiær system is a system for categorizing plants using life-form categories, devised by Danish botanist Christen C. Raunkiær and later extended by various ...
Note that this system was published well before there were internationally accepted rules for botanical nomenclature.It indicates a family by "ordo"; an order is indicated by "cohors" (in the first two volumes) or "series" (in the third volume); in the first two volumes “series” refers to a rank above that of order.
In his introduction, Linnaeus estimated that there were fewer than 10,000 plant species in existence; [12] there are now thought to be around 400,000 species of flowering plants alone. [13] The species were arranged in around a thousand genera, which were grouped into 24 classes, according to Linnaeus' sexual system of classification. [14]
Linné's method for classification of plants in Classes Plantarum 1738, and the Figurative system of human knowledge from Diderot's Encyclopédie, 1752. Classification chart or classification tree is a synopsis of the classification scheme, [1] designed to illustrate the structure of any particular field. Classification tree.webm
