Tricoccae
Euphorbiales is an order of flowering plants that is not currently recognized in the most authoritative modern treatment of plant taxonomy. In the APG II system (2003) the plants involved are mostly placed in the order Malpighiales. A well known system that did recognize the order was the Cronquist system (1981) which placed the order in subclass Rosidae and used this circumscription: *order Euphorbiales *: family Buxaceae *: family Simmondsiaceae *: family Euphorbiaceae (more broadly defined than in the APG II and III systems) *: family Pandaceae The family Pandaceae consists of three genera that were formerly recognized in the Euphorbiaceae. Those are: *''Galearia'' (from tribe Galearieae, subfamily Acalyphoideae, family Euphorbiaceae) *''Microdesmis'' (from tribe Galearieae, subfamily ...

Euphorbia Milii
''Euphorbia milii'', the crown of thorns, Christ plant, or Christ thorn, is a species of flowering plant in the spurge family Euphorbiaceae, native to Madagascar. The species name commemorates Baron Milius, once Governor of Réunion, who introduced the species to France in 1821. It is imagined that the species was introduced to the Middle East in ancient times, and legend associates it with the crown of thorns worn by Christ. It is commonly used as an ornamental houseplant that can be grown in warmer climates. The common name is due to the thorns and deep red bracts referring to the crown thorn Jesus had to wear during his crucifixion and his blood. Description It is a woody succulent subshrub or shrub growing to tall, with densely spiny stems. The straight, slender spines, up to long, help it scramble over other plants. The fleshy, green leaves are found mainly on new growth, and are up to long and broad. The flowers are small, subtended by a pair of conspicuous petal-li ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Group.Angiosperm Phylogeny Group (2003)An update of the Angiosperm Phylogeny Group classification for the orders and families of flowering plants: APG II.''Botanical Journal of the Linnean Society'' 141(4): 399-436. doi: 10.1046/j.1095-8339.2003.t01-1-00158.x It was a revision of the first APG system, published in 1998, and was superseded in 2009 by a further revision, the APG III system. History APG II was published as: *Angiosperm Phylogeny Group (2003). "An update of the Angiosperm Phylogeny Group classification for the orders and families of flowering plants: APG II".

Malpighiales
The Malpighiales comprise one of the largest orders of flowering plants, containing about 36 families and more than species, about 7.8% of the eudicots. The order is very diverse, containing plants as different as the willow, violet, poinsettia, manchineel, rafflesia and coca plant, and are hard to recognize except with molecular phylogenetic evidence. It is not part of any of the classification systems based only on plant morphology. Molecular clock calculations estimate the origin of stem group Malpighiales at around 100 million years ago ( Mya) and the origin of crown group Malpighiales at about 90 Mya. The Malpighiales are divided into 32 to 42 families, depending upon which clades in the order are given the taxonomic rank of family. In the APG III system, 35 families were recognized. Medusagynaceae, Quiinaceae, Peraceae, Malesherbiaceae, Turneraceae, Samydaceae, and Scyphostegiaceae were consolidated into other families. The largest family, by far, is the Euphorbiaceae, ...

Cronquist System
The Cronquist system is a taxonomic classification system of flowering plants. It was developed by Arthur Cronquist in a series of monographs and texts, including ''The Evolution and Classification of Flowering Plants'' (1968; 2nd edition, 1988) and ''An Integrated System of Classification of Flowering Plants'' (1981) (''see'' Bibliography). Cronquist's system places flowering plants into two broad classes, Magnoliopsida ( dicotyledons) and Liliopsida (monocotyledons). Within these classes, related orders are grouped into subclasses. While the scheme was widely used, in either the original form or in adapted versions, many botanists now use the Angiosperm Phylogeny Group classification for the orders and families of flowering plants, first developed in 1998. The system as laid out in Cronquist's ''An Integrated System of Classification of Flowering Plants'' (1981) counts 64 orders and 321 families in class Magnoliopsida and 19 orders and 65 families in class Liliopsida.

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.

Buxaceae
The Buxaceae are a small family of six genera and about 123 known species of flowering plants. They are shrubs and small trees, with a cosmopolitan distribution. A seventh genus, sometimes accepted in the past (''Notobuxus''), has been shown by genetic studies to be included within ''Buxus'' (Balthazar ''et al.'', 2000). The family is recognised by most taxonomists, and it is commonly known as the box family. However, its placement and circumscription has varied; some taxonomists treated '' Styloceras'' in its own family Stylocerataceae, ''Didymeles'' in its own family Didymelaceae, ''Haptanthus'' in Haptanthaceae (now all included in Buxaceae)), and formerly '' Simmondsia'' was included, which is not related and now usually placed in its own family Simmondsiaceae. The APG II system of 2003 recognises the family, but in a new circumscription in that it includes the genus ''Didymeles'' (two species of evergreen trees from Madagascar). However, APG II does allow the option of segr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simmondsiaceae
Simmondsiaceae or the jojoba family is a family of flowering plants. The family is not recognized by all taxonomic systems, the single species, ''Simmondsia chinensis'', often being treated as belonging to family Buxaceae. The APG II system, of 2003 (unchanged from the APG system, of 1998), does recognize this family and assigns it to the order Caryophyllales in the clade core eudicots. It consist of a single species only, jojoba (''Simmondsia chinensis''), of North American shrubs. The Cronquist system, 1981, had also recognized this family and placed it in order Euphorbiales Euphorbiales is an order of flowering plants that is not currently recognized in the most authoritative modern treatment of plant taxonomy.

Euphorbiaceae
Euphorbiaceae, the spurge family, is a large family of flowering plants. In English, they are also commonly called euphorbias, which is also the name of a genus in the family. Most spurges, such as ''Euphorbia paralias'', are herbs, but some, especially in the tropics, are shrubs or trees, such as ''Hevea brasiliensis''. Some, such as ''Euphorbia canariensis'', are succulent and resemble cacti because of convergent evolution. This family has a cosmopolitan global distribution. The greatest diversity of species is in the tropics, however, the Euphorbiaceae also have many species in nontropical areas of all continents except Antarctica. Description The leaves are alternate, seldom opposite, with stipules. They are mainly simple, but where compound, are always palmate, never pinnate. Stipules may be reduced to hairs, glands, or spines, or in succulent species are sometimes absent. The plants can be monoecious or dioecious. The radially symmetrical flowers are unisexual, w ...

Pandaceae
The family Pandaceae consists of three genera that were formerly recognized in the Euphorbiaceae. Those are: *''Galearia'' (from tribe Galearieae, subfamily Acalyphoideae, family Euphorbiaceae) *''Microdesmis'' (from tribe Galearieae, subfamily Acalyphoideae, family Euphorbiaceae) *''Panda'' (from tribe Galearieae, subfamily Acalyphoideae, family Euphorbiaceae) These genera contain 17 species, which especially live in West Africa or Southeast Asia. Species in this family are dioecious trees or shrubs, with alternate, simple leaves. The genus ''Centroplacus'' was formerly included in the Pandaceae and had also been recognized in the tribe Centroplaceae, family Phyllanthaceae). The APG III system recognized this genus as a part of the family Centroplacaceae Centroplacaceae is a family of flowering plants in the order Malpighiales and is recognized by the APG III system of classification. The family comprises two genera: ''Bhesa'', which was formerly recognized in the Celas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Historically Recognized Plant Orders
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...
