Linnaean taxonomy can mean either of two related concepts: The particular form of biological classification (taxonomy) set up by Carl Linnaeus, as set forth in his Systema Naturae (1735) and subsequent works. In the taxonomy of Linnaeus there are three kingdoms, divided into classes, and the classes divided into lower ranks in a hierarchical order.
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 ...
Systema Naturae (originally in Latin written Systema Naturæ with the ligature æ) is one of the major works of the Swedish botanist, zoologist and physician Carl Linnaeus (1707–1778) and introduced the Linnaean taxonomy. Although the system, now known as binomial nomenclature, was partially developed by the Bauhin brothers, Gaspard and ...
Early taxonomy was based on arbitrary criteria, the so-called "artificial systems", including Linnaeus's system of sexual classification for plants (Linnaeus's 1735 classification of animals was entitled "Systema Naturae" ("the System of Nature"), implying that he, at least, believed that it was more than an "artificial system").
Title page of the 10th edition of Systema Naturae. The 10th edition of Systema Naturae (Latin; the English title is A General System of Nature) is a book written by Swedish naturalist Carl Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature.
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]
Only five editions of Systema Naturae were written by Linnaeus himself, namely the first, second, sixth, tenth and twelfth. [2] When a "starting point" for zoological nomenclature was first considered, in the Strickland Code of 1843, the 12th edition of Systema Naturae was chosen, so that any names which Linnaeus had altered from previous editions would be recorded in their final state. [3]
Such improvements in technique made Linnaeus's Genera Plantarum the model for later works on the genera of plants." [10] Frans Stafleu regards Genera Plantarum as Linnaeus's most important book with respect to the practical introduction of his ideas – even more than Systema Naturae. The notion that the genus is the basic unit of taxonomy ...
