Gynandrae
{{Unreferenced, date=December 2009 ''Gynandrae'' is a botanical name of an order of flowering plants. It was used in the Wettstein system for the order containing the orchids and is a descriptive name referring to the stamens. The Bentham & Hooker and the Engler systems also used a descriptive name for this order, but preferred the name '' Microspermae''. In taxonomical systems these two descriptive names have now mostly dropped out of use, being displaced by the name ''Orchidales'' (formed from the family name ''Orchidaceae'').

Wettstein System
A system of plant taxonomy, the Wettstein system recognised the following main groups, according to Richard Wettstein's ''Handbuch der Systematischen Botanik'' (1901–1924). 3rd edition (1924) Outline Synopsis * Flagellatae p. 65 * Myxophyta p. 69 * Schizophyta ** Schizophyceae ** Schizomycetes * Zygophyta ** Peridinieae ** Bacillarieae *** Centricae *** Pennatae ** Conjugatae * Phaeophytae * Rhodophyta ** Bangieae ** Florideae * Euphallophyta ** Chlorophyceae ** Fungi *** Eumycetes **** Phycomycetes **** Ascomycetes **** Basidiomycetes *** Lichenes **** Ascolichenes **** Basidiolichenes * Cormophyta ** Archegoniatae *** Bryophyta **** Musci **** Hepaticae *** Pteridophyta **** Psilophytinae **** Lycopodiinae **** Psilotinae **** Equisetinae **** Isoëtinae **** Filicinae **** Cycadofilicinae ** Anthophyta *** Gymnospermae **** Cycadinae **** Bennettitinae **** Cordaitinae **** Gingkoinae **** Coniferae **** Gnetinae *** Angiospermae p. 467 **** Dicotyledone ...

Orchidales
{{Unreferenced, date=December 2009 ''Orchidales'' is an order of flowering plants. In taxonomical systems, this is a relatively recent name as early systems used descriptive botanical names for the order containing the orchids. The Bentham & Hooker and the Engler systems had the orchids in order ''Microspermae'' while the Wettstein system treats them as order ''Gynandrae''. Circumscription of the order will vary with the taxonomic system being used. Although mostly the order will consist of the orchids only (usually in one family only, but sometimes divided into more families, as in the Dahlgren system, see below), sometimes other families are added: Circumscription in the Takhtajan system Takhtajan system: * order ''Orchidales'' *: family ''Orchidaceae'' Circumscription in the Cronquist system Cronquist system (1981): * order ''Orchidales'' *: family ''Geosiridaceae'' *: family ''Burmanniaceae'' *: family ''Corsiaceae'' *: family ''Orchidaceae'' Circumscription in the Dahl ...

Orchid Phalaenopsis Hybrid
Orchids are plants that belong to the family Orchidaceae (), a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Along with the Asteraceae, they are one of the two largest families of flowering plants. The Orchidaceae have about 28,000 currently accepted species, distributed in about 763 genera. (See ''External links'' below). The determination of which family is larger is still under debate, because verified data on the members of such enormous families are continually in flux. Regardless, the number of orchid species is nearly equal to the number of bony fishes, more than twice the number of bird species, and about four times the number of mammal species. The family encompasses about 6–11% of all species of seed plants. The largest genera are ''Bulbophyllum'' (2,000 species), ''Epidendrum'' (1,500 species), ''Dendrobium'' (1,400 species) and ''Pleurothallis'' (1,000 species). It also includes ''Vanilla'' (the genus of the v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botanical Name
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Order (biology)
Order ( la, wikt:ordo#Latin, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between Family_(biology), family and Class_(biology), class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. Fo ...

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] |
Descriptive Name
In the study of language, description or descriptive linguistics is the work of objectively analyzing and describing how language is actually used (or how it was used in the past) by a speech community. François & Ponsonnet (2013). All academic research in linguistics is descriptive; like all other scientific disciplines, it seeks to describe reality, without the bias of preconceived ideas about how it ought to be. Modern descriptive linguistics is based on a structural approach to language, as exemplified in the work of Leonard Bloomfield and others. This type of linguistics utilizes different methods in order to describe a language such as basic data collection, and different types of elicitation methods. Descriptive versus prescriptive linguistics Linguistic description is often contrasted with linguistic prescription, — entry for "Descriptivism and prescriptivism" quotation: "Contrasting terms in linguistics." (p.286) which is found especially in education and in publi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
