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]

At one time, the cryptogams were formally recognised as a group within the plant kingdom. In his system for classification of all known plants and animals, Carl Linnaeus (1707–1778) divided the plant kingdom into 24 classes , [ 1 ] one of which was the "Cryptogamia".
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. The process of identification connects the specimen with a published name. Once a plant specimen has been identified, its name and properties are known.
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).

Combined with the five-kingdom model, this created a six-kingdom model, where the kingdom Monera is replaced by the kingdoms Bacteria and Archaea. [16] This six-kingdom model is commonly used in recent US high school biology textbooks, but has received criticism for compromising the current scientific consensus. [ 13 ]
The plant grows from a central, budding, fleshy structure with fleshy, radiating roots. Ophioglossum malviae is known as the world's smallest terrestrial fern. [ 4 ]
