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. ''An Integrated System of Classification of Flowering Plants''. Columbia University Press: New York, NY, USA. * subclass Rosidae The Phylocode definition includes Crossosomat ...

Euphorbiales
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, subfami ...

Rhamnales
The Rhamnales Lindl. are an order of dicotyledon plants in the subclass Rosidae. In the Cronquist system, the following families were placed here: * Family Elaeagnaceae – (Oleaster family) * Family Leeaceae * Family Rhamnaceae (buckthorn family) * Family Vitaceae ( grape family) ''Leea'' may be included within the Vitaceae. The Rhamnaceae are no longer considered close relatives of these other forms, and newer systems move them to the Rosales. The order then becomes the Vitales. Under the APG III system of classification, Rhamnales is not recognized. Instead, the families previously included here under the Cronquist system are included under the following orders: * Elaeagnaceae and Rhamnaceae are placed within Rosales Rosales () is an order of flowering plants.

Taxonomic Rank
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While older approaches to taxonomic classification were phenomenological, forming groups on the basis of similarities in appearance, organic structure and behaviour, methods based on genetic analysis have opened the road to cladistics. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of traits or features from common ancestors. The rank of any ''species'' and the description of its ''genus'' is ''basic''; which means that to identify a particular organism, it is usually not necessary to specify ranks other than these first two.

Rafflesiales
Rafflesiales is a botanical name of an order of flowering plants. The name was first published by Oliver in 1895. The Cronquist system used this name for an order placed in subclass Rosidae with the following circumscription (1981) : * order Rafflesiales *: family Hydnoraceae *: family Mitrastemonaceae *: family Rafflesiaceae The APG II system regards Rafflesiaceae as an unplaced family of three genera. Also unplaced is the genus '' Mitrastema''. However, APG II does have a placement for family Hydnoraceae, in the order Piperales. According to the AP-Website recent research places Rafflesiaceae in order 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, poinset .... Historically recognized angiosperm orders {{angiosperm-stub ...

Cornales
The Cornales are an order of flowering plants, early diverging among the asterids, containing about 600 species. Plants within the Cornales usually have four-parted flowers, drupaceous fruits, and inferior to half-inferior gynoecia topped with disc-shaped nectaries. Taxonomy In the classification system of Dahlgren the Cornales were in the superorder Corniflorae (also called Cornanae). Under the APG IV system, the Cornales order includes these families: * Cornaceae (the dogwood family) * Curtisiaceae (cape lancewood) * Grubbiaceae (the sillyberry family) * Hydrangeaceae (the hydrangea family) * Hydrostachyaceae * Loasaceae (the stickleaf family) * Nyssaceae, (the tupelos) The oldest fossils assigned with confidence to the order are '' Hironoia fusiformis'', described from Coniacian age Japanese coalified fruits, and '' Suciacarpa starrii'' described from American permineralized fruits of Campanian age.

Rosaceae
Rosaceae (), the rose family, is a medium-sized family of flowering plants that includes 4,828 known species in 91 genera. The name is derived from the type genus ''Rosa''. Among the most species-rich genera are '' Alchemilla'' (270), ''Sorbus'' (260), '' Crataegus'' (260), '' Cotoneaster'' (260), ''Rubus'' (250), and ''Prunus'' (200), which contains the plums, cherries, peaches, apricots, and almonds. However, all of these numbers should be seen as estimates—much taxonomic work remains. The family Rosaceae includes herbs, shrubs, and trees. Most species are deciduous, but some are evergreen. They have a worldwide range but are most diverse in the Northern Hemisphere. Many economically important products come from the Rosaceae, including various edible fruits, such as apples, pears, quinces, apricots, plums, cherries, peaches, raspberries, blackberries, loquats, strawberries, rose hips, hawthorns, and almonds. The family also includes popular ornamental trees and sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proteales
Proteales is an order of flowering plants consisting of three (or four) families. The Proteales have been recognized by almost all taxonomists. The representatives of the Proteales are very different from each other. The order contains plants that do not look alike at all. What they have in common is seeds with little or no endosperm. The ovules are often atropic. Families In the classification system of Dahlgren the Proteales were in the superorder Proteiflorae (also called Proteanae). The APG II system of 2003 also recognizes this order, and places it in the clade eudicots with this circumscription: * order Proteales :* family Nelumbonaceae :* family Proteaceae family Platanaceae">Platanaceae.html" ;"title=" family Platanaceae"> family Platanaceae with "+ ..." = optionally separate family (that may be split off from the preceding family). The APG III system of 2009 followed this same approach, but favored the narrower circumscription of the three families, firmly 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.

Stellaria Media
''Stellaria media'', chickweed, is an annual and perennial flowering plant in the family Caryophyllaceae.Fernald, M. L. 1950. “Gray's Manual of Botany”. Eight Edition. American Book Company, New York, NY. 1632 pp. It is native to Eurasia and naturalized throughout the world. This species is used as a cooling herbal remedy, and grown as a vegetable crop and ground cover for both human and poultry consumption. It is sometimes called common chickweed to distinguish it from other plants called chickweed. Other common names include chickenwort, craches, maruns, and winterweed. The plant germinates in autumn or late winter, then forms large mats of foliage. Description This species is an annual in colder climates, becoming evergreen and perennial in warmer zones, with weak slender stems, up to . Plants are sparsely hairy. ''Stellaria media'' has one line of fine hairs on the stem. The leaves are oval and opposite, the lower ones with stalks. Flowers are white and small with ...

Celastrales
The Celastrales are an order of flowering plants found throughout the tropics and subtropics, with only a few species extending far into the temperate regions. The 1200"Lepidobotryaceae", "Parnassiaceae", and "Celastraceae" In: Klaus Kubitzki (ed.). ''The Families and Genera of Vascular Plants'' vol. VI. Springer-Verlag: Berlin;Heidelberg, Germany. (2004). (vol. VI). to 1350Peter F. Stevens (2001 onwards)CelastralesAtaMissouri Botanical Garden/ref> species are in about 100 genera. All but seven of these genera are in the large family Celastraceae. Until recently, the composition of the order and its division into families varied greatly from one author to another. Description The Celastrales are a diverse order that has no conspicuous distinguishing characteristic, so is consequently hard to recognize. The flowers are usually small with a conspicuous nectary disk. The stipules are small or rarely absent. The micropyle has two openings and is therefore called a bistoma ...

Santalales
The Santalales are an order of flowering plants with a cosmopolitan distribution, but heavily concentrated in tropical and subtropical regions. It derives its name from its type genus ''Santalum'' (sandalwood). Mistletoe is the common name for a number of parasitic plants within the order. Overview Many of the members of the order are parasitic plants, mostly hemiparasites, able to produce sugars through photosynthesis, but tapping the stems or roots of other plants to obtain water and minerals; some (e.g. ''Arceuthobium'') are obligate parasites, have low concentrations of chlorophyll within their shoots (1/5 to 1/10 of that found in their host's foliage), and derive the majority of their sustenance from their hosts' vascular tissues (water, micro- and macronutrients, and sucrose). Most have seeds without testae (seed coats), which is unusual for flowering plants. Classification The APG IV system of 2016 includes seven families. As in the earlier APG III system, it was acc ...

Rhizophorales
The Rhizophoraceae is a family of tropical or subtropical flowering plants. It includes around 147 species distributed in 15 genera.Setoguchi, H., Kosuge, K., & Tobe, H. (1999). Molecular Phylogeny of Rhizophoraceae Based on rbcL Gene Sequences. ''Journal of Plant Research'', ''112''(4), 443–455. https://doi.org/10.1007/PL00013899 Under the family, there are three tribes, Rhizophoreae, Gynotrocheae, and Macarisieae. Even though Rhizophoraceae is known for its mangrove members, only the genera under Rhizophoreae grow in the mangrove habitats and the remaining members live in inland forests. Taxonomy This family is now placed in the order Malpighiales, though under the Cronquist system, they formed an order in themselves (Rhizophorales).Juncosa, A. M., & Tomlinson, P. B. (1988).
