Reveal System
A 20th-century system of plant taxonomy, the Reveal system (see also the Thorne & Reveal system) of plant classification was drawn up by the American botanist James Reveal (1941-2015). The system was published online in 1997 in ten parts as lecture notes comparing the major systems in use at that time. Subsequently, Reveal became an author with the consensus Angiosperm Phylogeny Group (APG) on the APG II 2003 and APG III 2009 processes. Although this largely supplanted the earlier and competing systems, he collaborated with Robert Thorne on his system (2007), and subsequently continued to develop his own system. 1997 system * division Magnoliophyta angiosperms*: class Magnoliopsida *:: subclass Magnoliidae *: class Piperopsida *:: subclass Piperidae *:: subclass Nymphaeidae *:: subclass Nelumbonidae *: class Liliopsida monocots*:: subclass Triurididae *:: subclass Aridae *:: subclass Liliidae *:: subclass Arecidae *:: subclass Commelinidae *:: subclass Zingiberidae ...

List Of Systems Of Plant Taxonomy
This list of systems of plant taxonomy presents "taxonomic systems" used in plant classification. A wiktionary:taxonomic system, taxonomic system is a coherent whole of alpha taxonomy, taxonomic judgments on circumscription (taxonomy), circumscription and placement of the considered taxa. It is only a "system" if it is applied to a large group of such taxa (for example, all the flowering plants). There are two main criteria for this list. A system must be alpha taxonomy, taxonomic, that is deal with many plants, by their botanical names. Secondly it must be a system, i.e. deal with the relationships of plants. Although thinking about relationships of plants had started much earlier (see history of plant systematics), such systems really only came into being in the 19th century, as a result of an ever-increasing influx from all over the world of newly discovered plant species. The 18th century saw some early systems, which are perhaps precursors rather than full taxonomic systems ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commelinidae
In plant taxonomy, commelinids (originally commelinoids) (plural, not capitalised) is a clade of flowering plants within the monocots, distinguished by having cell walls containing ferulic acid. The commelinids are the only clade that the APG IV system has informally named within the monocots. The remaining monocots are a paraphyletic unit. Also known as the commelinid monocots it forms one of three groupings within the monocots, and the final branch; the other two groups are the alismatid monocots and the lilioid monocots. Description Members of the commelinid clade have cell walls containing UV-fluorescent ferulic acid. Taxonomy The commelinids were first recognized as a formal group in 1967 by Armen Takhtajan, who named them the Commelinidae and assigned them to a subclass of Liliopsida (monocots). The name was also used in the 1981 Cronquist system. However, by the release of his 1980 system of classification, Takhtajan had merged this subclass into a larger one, and no ...

Winterales
Canellales is the botanical name for an order of flowering plants, one of the four orders of the magnoliids. It is recognized by the most recent classification of flowering plants, the APG IV system. It is defined to contain two families: Canellaceae and Winteraceae, which comprise 136 species of fragrant trees and shrubs. The Canellaceae are found in tropical America and Africa, and the Winteraceae are part of the Antarctic flora (found in diverse parts of the southern hemisphere). Although the order was defined based on phylogenetic studies, a number of possible synapomorphies have been suggested, relating to the pollen tube, the seeds, the thickness of the integument, and other aspects of the morphology. Until 1999, these two families were not considered to be closely related. Instead the Winteraceae were considered to be a primitive family (due to the structure of the xylem and carpel, a structure which now seems to be derived from xylem and carpels more typical of the a ...

Magnolianae
Magnoliids (or Magnoliidae or Magnolianae) are a clade of flowering plants. With more than 10,000 species, including magnolias, nutmeg, bay laurel, cinnamon, avocado, black pepper, tulip tree and many others, it is the third-largest group of angiosperms after the eudicots and monocots. The group is characterized by trimerous flowers, pollen with one pore, and usually branching-veined leaves. Some members of the subclass are among the earliest angiosperms and share anatomical similarities with gymnosperms like stamens that resemble the male cone scales of conifers and carpels found on the long flowering axis. Classification "Magnoliidae" is the botanical name of a subclass, and "magnoliids" is an informal name that does not conform to the International Code of Nomenclature for algae, fungi, and plants. The circumscription of a subclass will vary with the taxonomic system being used. The only requirement is that it must include the family Magnoliaceae. The informal name "ma ...

Asteridae
''Asteridae'' is an obsolete botanical name at the rank of subclass. Composition of the subclass has also varied; however, by definition it always includes the family Asteraceae (Compositae). In the modern APG IV system of classification, asterid and euasterid are names for clades with a composition similar to that of Asteridae. One of the better-known and more influential systems that formally recognized subclass Asteridae was the Cronquist system devised by botanist Arthur Cronquist, which included the orders: * Gentianales * Solanales * Lamiales * Callitrichales * Plantaginales * Scrophulariales * Campanulales * Rubiales * Dipsacales * Calycerales * Asterales Most of the above orders as defined by Cronquist have definitely been dramatically redefined on the basis of recent molecular systematic studies. To a large extent Cronquist's subclass Asteridae corresponds with the older concepts of Sympetalae and Tubiflorae, groups that were defined by having their petals united ...

Lamiidae
The order Lamiales (also known as the mint order) are an order in the asterid group of dicotyledonous flowering plants. It includes about 23,810 species, 1,059 genera, and is divided into about 25 families. These families include Acanthaceae, Bignoniaceae, Byblidaceae, Calceolariaceae, Carlemanniaceae, Gesneriaceae, Lamiaceae, Lentibulariaceae, Linderniaceae, Martyniaceae, Mazaceae, Oleaceae, Orobanchaceae, Paulowniaceae, Pedaliaceae, Peltantheraceae, Phrymaceae, Plantaginaceae, Plocospermataceae, Schlegeliaceae, Scrophulariaceae, Stilbaceae, Tetrachondraceae, Thomandersiaceae, Verbenaceae. Being one of the largest orders of flowering plants, Lamiales have representatives found all over the world. Well-known or economically important members of this order include lavender, lilac, olive, jasmine, the ash tree, teak, snapdragon, sesame, psyllium, garden sage, and a number of table herbs such as mint, basil, and rosemary.

Rosidae
Under the International Code of Nomenclature for algae, fungi, and plants (ICN), Rosidae is a botanical name at the rank of subclass. Circumscription of the subclass will vary with the taxonomic system being used; the only requirement being that it includes the family Rosaceae. Under Phylocode, Rosidae is a clade defined as the most inclusive crown clade containing '' Rosa cinnamomea'',''sensu'' L. 1753 ''non'' L. 1759 but not '' Berberidopsis corallina'' nor '' Dillenia indica'' nor ''Gunnera manicata'' nor ''Helianthus annuus'' nor '' Saxifraga mertensiana'' nor ''Stellaria media'' nor '' Viscum album''. A well-known example of Rosidae as governed by the ICN was in the Cronquist system. In the 1981, original, version of that system, the circumscription was as follows. Arthur John Cronquist. 1981.

Dilleniidae
Dillenidae is a botanical name at the rank of subclass. Circumscription of the subclass will vary with the taxonomic system being used; the only requirement being that it includes the family Dilleniaceae. A well-known system that uses this name is the Cronquist system, and in the original 1981 version of the system the circumscription was: * subclass Dilleniidae *: order Dilleniales *: order Theales *: order Malvales *: order Lecythidales *: order Nepenthales *: order Violales *: order Salicales *: order Capparales *: order Batales *: order Ericales *: order Diapensiales *: order Ebenales *: order Primulales Recent molecular systematic studies have shown that this group is polyphyletic. The APG II system does not use formal botanical names above the rank of order but assigns the plants involved to various orders in the asterids and rosids clades.

Hamamelididae
Hamamelididae is an obsolete botanical name at the rank of subclass. Because some hamamelidid members bear aments (''i.e.'', catkins), this subclass has been formerly known as ''Amentiferae''. Based on molecular phylogeny works, Hamamelididae appears to be a polyphyletic group.Savolainen, V., M. W. Chase, S. B. Hoot, C. M. Morton, D. E. Soltis, C. Bayer, M. F. Fay, A. Y. De Bruijn, S.

(28 authors). 2011. "Angiosperm phylogeny: 17 genes, 640 taxa". ''American Journal of Botany'' 98(4):704-730. A well-known system that used the name Hamamelididae is the Cronquist system, although in the disallowed spelling ''Hamamelidae''. In the original 1981 version of this system the circumscription was: * subclass Hamamelidae *: order Trochodendrales *: order Hamamelidales *: order Daphniphylla ...

Caryophyllidae
Caryophyllidae is a botanical name at the rank of subclass. At the moment there is no complete consensus about what orders it includes, except that it presumably contains the order Caryophyllales. Note that this is only a naming difficulty: what to call various taxa of plants; there is little debate about how the plants in question are related. A well-known system that used this name is the Cronquist system, and in the original, 1981, version of this system the circumscription was: * subclass Caryophyllidae *: order Caryophyllales *: order Polygonales *: order Plumbaginales These plants form the order Caryophyllales in the APG II system The APG II system (Angiosperm Phylogeny Group II system) of plant classification is the second, now obsolete, version of a modern, mostly molecular-based, system of plant taxonomy that was published in April 2003 by the Angiosperm Phylogeny Gr ..., 2003.

Rosopsida
Rosopsida (Batsch, 1788) is a botanical name for a group of flowering plants recognized at the rank of class. The name is derived from that of the included family Rosaceae. As used in the Reveal system it is a subset of the dicots, a paraphyletic group recognized at various ranks in other systems, and includes: :* subclass Caryophyllidae :* subclass Hamamelididae :* subclass Dilleniidae :* subclass Rosidae :* subclass Cornidae :* subclass Lamiidae :* subclass Asteridae Reveal's use of the group corresponds largely to Cronquist's class Magnoliopsida (but minus subclass Magnoliidae) and to the eudicots of the APG II system minus Ranunculales and some other early-branching groups. The name has not been used in most of the more influential recent classification systems, such as the Cronquist system, the Thorne system, the Takhtajan system or the APG II The APG II system (Angiosperm Phylogeny Group II system) of plant classification is the second, now obsolete, version of a ...
