As mentioned on the Taxonomic History page, there have been so many systems through time. This page list some of the most recent, and link to a page with more details.



1753 Carl Linnaeus' system, published in Species Plantarum 1753 was a toughly milestone in taxonomy, where the binomial nomenclature were introduced. He abandoned the long descriptive names of classes and orders and two-word generic names and used Joseph Pitton de Tournefort way of description.
1862 George Bentham (1800-1884) made a system together with Joseph Dalton Hooker (1817-1911) which were published in Genera plantarum ad exemplaria imprimis in herbariis kewensibus servata definita (1-3) 1862–1883
1887 Heinrich Gustav Adolf Engler (Adolf Engler) (1844–1930) and Karl Anton Eugen Prantl (1849-1893) made the Engler and Prantl or Phylogenetic System, published in Die Natürlichen Pflanzenfamilien 1887-1915
1901 Richard Wettstein (Ritter von Westersheim) (1863-1931) published his system in Handbuch der systematischen Botanik from 1901-1935.
1915 Charles Edwin Bessey (1845-1915) made his Bessey system, with focus on the evolutionary divergence of primitive forms.
1934 John Hutchinson's System was published in his  two volumes: Monocotyledonae in 1926, and Dicotyledonae in 1934 (2nd edition 1959; 3rd edition, 1973).
1966 Armen Leonovich  (1910-2009) (Армен Левонович Тахтаджян, Takhtadjan or Takhtadzhian) published his Angiosperm Classification in A system and phylogeny of the flowering plants in1966
1975 Rolf Martin Theodor Dahlgren (1932-1987) made his Angiosperm Classification in 1975.
1981 Arthur John Cronquist (1919-1991). Made his Angiosperm Classification from 1981-1988
1986 Aaron Goldberg's system were published his Classification, Evolution and Phylogeny of the Families of Dicotyledons in Smithsonian Contributions to Botany 58: 1–314 in 1986 and the Classification, Evolution and Phylogeny of the Families of Monocotyledons came in 1989 in Smithsonian Contributions to Botany 71: 1–73.
1990 Klaus Kubitzki (1933-) Made a system that were publishing in Kubitzki, K 1990- with the title: The families and genera of vascular plants.
1992 Robert Folger Thorne (1920-2015) made his Angiosperm Classification in 1992. It was  published in Classification and geography of the flowering plants.
1996 James Lauritz  Reveal (1941-2015) made his Angiosperm Classification in 1996.
1999 The APG system (I) is "An ordinal classification for the families of flowering plants". It was the first system to use the PholyCode system from Harvard University, and this is the first, not complete work. It is the first taxonomic work, done by a larger group of systematic botanists, worldwide. It were published in Annals of the Missouri Botanical Garden 85: 531–553. W.S. Judd & al. (1999; 2nd edition, 2002), with the title: Plant systematics: a phylogenetic approach
2003 The PhyloCode work on plants is done by the Angiosperm Phylogeny Group, known as APG II, is based on evolution, discovered through DNA tests of three genes. Their second edition were published in Botanical Journal of the Linnean Society 141: 399-436, 2003.
2009 APG III was published on the 8. of October 2009.
2016 APG IV was published on the 6. of April 2016.
2016 With the DNA mapping, the latest system is PPG I for the spore-plants, just like APG IV 2016 for the Angiosperms; the flowering plants.
