Three goals of plant taxonomy are the identification, classification and description of plants. The distinction between these three goals is important and often overlooked. Plant identification is a determination of the identity of an unknown plant by comparison with previously collected specimens or with the aid of books or identification manuals.
But despite the development from two kingdoms to five among most scientists, some authors as late as 1975 continued to employ a traditional two-kingdom system of animals and plants, dividing the plant kingdom into subkingdoms Prokaryota (bacteria and cyanobacteria), Mycota (fungi and supposed relatives), and Chlorota (algae and land plants).

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 ...
This article lists the living orders of the Viridiplantae, based primarily on the work of Ruggiero et al. 2015. [1] Living order of Lycophytes and ferns are taken from Christenhusz et al. 2011b [2] and Pteridophyte Phylogeny Group. [3]
In seed plants (gymnosperms and flowering plants), the sporophyte forms most of the visible plant, and the gametophyte is very small. Flowering plants reproduce sexually using flowers, which contain male and female parts: these may be within the same ( hermaphrodite ) flower, on different flowers on the same plant , or on different plants .
His 2004 classification treated the archaeobacteria as part of a subkingdom of the kingdom Bacteria, i.e., he rejected the three-domain system entirely. [72] Stefan Luketa in 2012 proposed a five "dominion" system, adding Prionobiota ( acellular and without nucleic acid ) and Virusobiota (acellular but with nucleic acid) to the traditional ...
A. W. Eichler. A system of plant taxonomy, the Eichler system was the first phylogenetic (phyletic) or evolutionary system. [1] [2] It was developed by August W. Eichler (1839–1887), initially in his Blüthendiagramme (1875–1878) and then in successive editions of his Syllabus (1876–1890).
A taxonomic system for seed plants was published in Bentham and Hooker's Genera plantarum ad exemplaria imprimis in herbariis kewensibus servata definita in three volumes between 1862 and 1883. [1] [2]
