Learn about the science and history of plant taxonomy, the branch of biology that identifies, describes, classifies, and names plants. Explore the different systems of plant classification, from the traditional dichotomous division of dicots and monocots to the modern phylogenetic approach based on molecular data.
Taxonomy is the scientific study of naming, defining and classifying groups of biological organisms based on shared characteristics. Learn about the origins, principles, ranks, methods and challenges of taxonomy, as well as its relation to systematics and evolutionary biology.
Systema Naturae is a major work by Carl Linnaeus that introduced the Linnaean taxonomy and the binomial nomenclature. It covers the classification of plants, animals and minerals into three kingdoms and five levels, based on God's creation and natural traits.
Learn about the biological classification system of Carl Linnaeus, who divided organisms into three kingdoms and used binomial names. See the key to his sexual system of plants and the difference between Linnaean and modern taxonomy.

Learn about the history and classification of kingdoms in biology, from the ancient dichotomy of animals and plants to the modern three-domain system of prokaryotes and eukaryotes. Find out how kingdoms are defined, divided, and named in different taxonomic schemes.
An identification key is a device that aids the identification of biological or other entities based on their features. Learn about the principles, types, and problems of identification keys in biology and other fields.
Systematics is the study of the diversification and relationships of living forms, both past and present, using evolutionary trees. It is also known as systematic biology, taxonomy, biosystematics, or phylogenetics, and involves various methods and tools such as molecular characters, cladistics, and biochemical systematics.
