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.

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 (biology), 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 Galea ... References Historically recognized plant orders {{Rosid-stub ...

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 (, ) are an order of flowering plants.

Taxonomic Rank
In biology, taxonomic rank (which some authors prefer to call nomenclatural rank because ranking is part of nomenclature rather than taxonomy proper, according to some definitions of these terms) is the relative or absolute level of a group of organisms (a ''taxon'') in a hierarchy that reflects evolutionary relationships. Thus, the most inclusive clades (such as Eukarya and Animalia) have the highest ranks, whereas the least inclusive ones (such as ''Homo sapiens'' or ''Bufo bufo'') have the lowest ranks. Ranks can be either relative and be denoted by an indented taxonomy in which the level of indentation reflects the rank, or absolute, in which various terms, such as species, genus, Family (biology), family, Order (biology), order, Class (biology), class, Phylum (biology), phylum, Kingdom (biology), kingdom, and Domain (biology), domain designate rank. This page emphasizes absolute ranks and the rank-based codes (the International Code of Zoological Nomenclature, Zoological Code, ...

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 Order (biology), orders of flowering plants. The order is very diverse, with well-known members including willows, Viola (plant), violets, aspens and Populus, poplars, Euphorbia pulcherrima, poinsett ....

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 family of flowering plants that includes 4,828 known species in 91 genera. The name is derived from the type genus '' Rosa''. The family 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 shrubs, such as roses, meadowsweets, rowans, firethorns, and photinias. Among the most species-rich genera in the family 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 th ... [...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 can be very different from each other due to their very early divergence. They possess seeds with little or no endosperm. The oldest fossils of Proteales are of the nelumbonaceous genus '' Notocyamus'' from the Barremian stage of the Early Cretaceous of Brazil, 126–121 Ma (million years ago). According to molecular clock calculations, the lineage that led to Proteales split from other plants about 128 Ma or 125 Ma. Families Within the classification system of Rolf Dahlgren, the Proteales were in the superorder Proteiflorae, also called Proteanae; The APG II system (of 2003) also recognizes this order, placing it in the clade Eudicots, with the following circumscription: * order Proteales :* family Nelumbonaceae :* family Proteaceae Platanaceae.html" ;"title=" family Platanaceae"> family Plata ...

Cronquist System
The Cronquist system is a list of systems of plant taxonomy, taxonomic classification system of angiosperms, 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, 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 a ...

Stellaria Media
''Stellaria media'', chickweed, is an annual flowering plant in the family Caryophyllaceae. It is native to Eurasia and naturalized throughout the world, where it is a weed of waste ground, farmland and gardens. It is sometimes grown as a salad crop or for poultry consumption. Description Chickweed is a hardy annual which flowers throughout the year in northern Europe, in mild weather. The stems are terete and glabrous with a lax and sprawling growth habit, up to long and in diameter, with a line (very occasionally 2 lines) of hairs running straight down its length, alternating sides at the nodes. The petioles are 5 to 8 mm long with hairy margins. The leaves are green, hairless, oval and opposite, long by wide with a hydathode at the tip. The flowers are small, less than 1 cm in diameter, with 5 white petals, 1–3 mm long, nestled inside the larger (3–5 mm long) sepals. These sepals have long, wavyvillous hairs on their outer (distal) sides and are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Santalales
The Santalales are an order (biology), order of flowering plants in the dicotyledons. Well-known members of the Santalales include Santalum, sandalwoods and the many species of mistletoes. The order has a cosmopolitan distribution, but is heavily concentrated in tropical and subtropical regions. It derives its name from its type genus, ''Santalum'' (sandalwood). 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, micronutrient, micro- and macronutrients, and sucrose). Most have seeds without testa (botany), testae (seed coats), which is unusual for flowering plants. Classif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. 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). A Historical and Taxonomic Synopsis of Rhizophoraceae and Anisophylleaceae. ''Annals of the Missouri Botanical Garden'', ''75''(4), 1278. It is sister group to Erythroxylaceae.
