Violales
Violales is a botanical name of an order of flowering plants and takes its name from the included family Violaceae; it was proposed by Lindley (1853). The name has been used in several systems, although some systems used the name Parietales for similar groupings. In the 1981 version of the influential Cronquist system, order Violales was placed in subclass Dilleniidae with a circumscription consisting of the families listed below. Some classifications such as that of Dahlgren placed the Violales in the superorder Violiflorae (also called Violanae). The Angiosperm Phylogeny Group (APG) system does not recognize order Violales; Violaceae is placed in order Malpighiales and the other families are reassigned to various orders as indicated. * order Violales Perleb 1826 *: family Achariaceae → order Malpighiales *: family Ancistrocladaceae → order Caryophyllales *: family Begoniaceae → order Cucurbitales *: family Bixaceae → order Malvales *: family Caricaceae → orde ...

Violaceae
Violaceae is a family of flowering plants established in 1802, consisting of about 1000 species in about 25 genera. It takes its name from the genus ''Viola'', the violets and pansies. Older classifications such as the Cronquist system placed the Violaceae in an order named after it, the Violales or the Parietales. However, molecular phylogeny studies place the family in the Malpighiales as reflected in the Angiosperm Phylogeny Group (APG) classification, with 41 other families, where it is situated in the parietal clade of 11 families. Most of the species are found in three large genera, ''Viola'', ''Rinorea'' and ''Hybanthus''. The other genera are largely monotypic or oligotypic. The genera are grouped into four clades within the family. The species are largely tropical or subtropical but ''Viola'' has a number of species in temperate regions. Many genera have a very restricted distribution. Description Though the best-known genus, ''Viola'', is herbaceous, most species are ...

Parietales
''Parietales'' is an order of flowering plants. It is a descriptive botanical name for ''placentae parietales'' (parietal placentation) that characterised those plants. Thus it could be used even today (for a taxon above the rank of family). The termination -''ales'' is only coincidentally identical to that appropriate to the rank of order. The name was used in several systems, such as (Bentham and Hooker, Engler and Prantl, Melchior), and Wettstein, etc. although more recent systems such as the Cronquist system preferred the name ''Violales''. It persists as the parietal clade of 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, poinsett .... References Bibliography * * Historically recognized angiosperm orders {{rosid-stub ...

Bixaceae
The Bixaceae are a family of dicotyledonous plants commonly called the achiote family. Under the Cronquist system, the family was traditionally placed in the order Violales. However, newer arrangements move it, with some other families previously in the Violales, into the Malvales. Although small, this family includes trees, herbs, and shrubs. The plants are bisexual, and all species have five sepals. All plants within the Bixaceae produce a red, orange, or yellow latex. Genera The Bixaceae include three genera and a total of 25 species, although ''Cochlospermum'' is sometimes placed into its own family Cochlospermaceae. The best-known species is the source of annatto, the achiote, which belongs to the type genus of the family. *''Bixa'' *'' Cochlospermum'' ('' Amoreuxia'' is now a synonym) *''Diegodendron ''Diegodendron'' is a monotypic genus of flowering plants belonging to the family Bixaceae.

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, ...

Cucurbitales
The Cucurbitales are an order of flowering plants, included in the rosid group of dicotyledons. This order mostly belongs to tropical areas, with limited presence in subtropical and temperate regions. The order includes shrubs and trees, together with many herbs and climbers. One major characteristic of the Cucurbitales is the presence of unisexual flowers, mostly pentacyclic, with thick pointed petals (whenever present). The pollination is usually performed by insects, but wind pollination is also present (in Coriariaceae and Datiscaceae). The order consists of roughly 2600 species in eight families. The largest families are Begoniaceae (begonia family) with around 1500 species and Cucurbitaceae (gourd family) with around 900 species. These two families include the only economically important plants. Specifically, the Cucurbitaceae (gourd family) include some food species, such as squash, pumpkin (both from ''Cucurbita''), watermelon (''Citrullus vulgaris''), and cucumber and mel ...

Fouquieriaceae
''Fouquieria'' is a genus of 11 species of desert plants, the sole genus in the Family (biology), family Fouquieriaceae. The genus includes the ocotillo (''Fouquieria splendens, F. splendens'') and the Boojum tree or cirio (''Fouquieria columnaris, F. columnaris''). They have semisucculent stems with thinner spikes projecting from them, with leaf, leaves on the bases spikes. They are unrelated to cactus, cacti and do not look much like them; their stems are proportionately thinner than cactus stems and their leaves are larger. Taxonomy Taxonomic history ''Fouquieria'' species do not have a particularly close resemblance to any other sort of plants; genetic evidence has shown they belong in the Ericales. Before this, they had been variously placed in the Violales or their own order, Fouquieriales. The Seri people identify three species of ''Fouquieria'' in their area of Mexico: ''jomjéeziz'' or ''xomjéeziz'' (''Fouquieria splendens, F. splendens''), ''jomjéeziz caacöl'' ...

Malvales
The Malvales are an order of flowering plants. As circumscribed by APG II-system, the order includes about 6000 species within 9 families. The order is placed in the eurosids II, which are part of the eudicots. The plants are mostly shrubs and trees; most of its families have a cosmopolitan distribution in the tropics and subtropics, with limited expansion into temperate regions. An interesting distribution occurs in Madagascar, where three endemic families of Malvales (Sphaerosepalaceae, Sarcolaenaceae and Diegodendraceae) occur. Many species of Malvaceae ''sensu lato'' are known for their wood, with that of ''Ochroma'' (balsa) being known for its lightness, and that of ''Tilia'' (lime, linden, or basswood) as a popular wood for carving. Fruit of the cacao tree (''Theobroma cacao'') are used as an ingredient for chocolate. Kola nuts (genus ''Cola'') are notable for their high content of caffeine and, in past, were commonly used for preparing of various cola drinks. Other well-k ...

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.

Dioncophyllaceae
The Dioncophyllaceae are a family of flowering plants consisting of three species of lianas native to the rainforests of western Africa. Their closest relatives are Ancistrocladaceae. Both families lie within a clade of mostly carnivorous plants which, since 1998 or so, have been moved to the order Caryophyllales. This clade also includes the families Droseraceae (sundews and Venus' flytrap) and Nepenthaceae (an Old World genus of pitcher plants), as well as Drosophyllaceae. All species in the family are lianas at some point in their lifecycles, and climb by the use of pairs of hooks or tendrils formed by the end of the leaf midribs. The best-known member is the carnivorous '' Triphyophyllum peltatum'', although the family contains two other species: ''Habropetalum dawei'' and ''Dioncophyllum thollonii''. History of classification The Cronquist system (1981) had placed the family in order Violales. The APG II system, of 2003 (unchanged from the APG system, of 1998), does rec ...

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.

Ancistrocladaceae
''Ancistrocladus'' is a genus of woody lianas in the monotypic family ''Ancistrocladaceae''. The branches climb by twining other stems or by scrambling with hooked tips. They are found in the tropics of the Old World. Classification The APG II system, of 2003 (unchanged from the APG system, of 1998), also recognizes this family and assigns it to the order Caryophyllales in the clade core eudicots. Recent molecular and biochemical evidence (see thAP-Website suggests the carnivorous taxa in the order Caryophyllales (the families Droseraceae and Nepenthaceae and the species ''Drosophyllum lusitanicum'' and '' Triphyophyllum peltatum'') all belong to the same clade. This family Ancistrocladaceae would belong to this same clade, although the plants in the family are not carnivorous. A close relationship between this family and the family Dioncophyllaceae (containing the carnivorous species ''T. peltatum'') is supported by similar pollen and petiole structure.

Datiscaceae
The Datiscaceae are a family of dicotyledonous plants, containing two species of the genus ''Datisca''. Two other genera, ''Octomeles'' and ''Tetrameles'', are now classified in the family Tetramelaceae. Datiscaceae are large herbaceous plants, with alternate and pinnate leaves. They are actinorhizal plants, that host nitrogen-fixing bacteria in their roots, and are the only ones that are non-woody, although non-actinorrhizal plants also fix nitrogen, such as the legumes. Species The genus ''Datisca'' contains two or three species; two from Asia and one from North America. The species ''Datisca cannabina'' is found in Crete and Turkey, and closely related ''Datisca nepalensis'' is found in the Himalayas, and is sometimes included in ''D. cannabina''. It grows to about 2.0 m tall, and in May to August it produces small greenish-yellow flowers. This species is strictly dioecious, with male and female flowers on different plants. It is grown for ornamental foliage and can be use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
