Principes (botany)
Arecales is an order of flowering plants. The order has been widely named as such only for the past few decades; until then, the accepted name for the order including these plants was Principes. The order includes palms and relatives. Taxonomy The APG IV system of 2016 places Dasypogonaceae in this order, after studies showing Dasypogonaceae as sister to Arecaceae. However, this decision has been called into question. Historical taxonomical systems The Cronquist system of 1981 assigned the order to the subclass Arecidae in the class Liliopsida (= monocotyledons). The Thorne system (1992) and the Dahlgren system assigned the order to the superorder Areciflorae, also called Arecanae in the subclass Liliidae (= monocotyledons), with the single family Arecaceae. The APG II system of 2003 recognised the order and placed it in the clade commelinids in the monocots and uses this circumscription: * order Arecales *: family Arecaceae, alternative name Palmae This was unchanged f ...

Areca Catechu
''Areca catechu'' is a species of palm native to the Philippines cultivated for areca nuts. It was carried widely through the tropics by the Austronesian migrations and trade since at least 1500 BCE due to its use in betel nut chewing. It is widespread in cultivation and is considered naturalized in much of tropical Asia and in Taiwan, southern China (Guangxi, Hainan, Yunnan), Madagascar, parts of the Pacific Islands, and also in the West Indies. : : :This review cites this research. : : Its fruits (called areca nuts or betel nuts) are chewed together with slaked lime and betel leaves for their stimulant and narcotic effects. Taxonomy Common names in English include areca palm, areca nut palm, betel palm, betel nut palm, Indian nut, Pinang palm and catechu. This palm is commonly called the betel tree because its fruit, the areca nut, which are often chewed along with the betel leaf, a leaf from a vine of the family Piperaceae. The species was first published by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liliidae
Liliidae is a botanical name at the rank of subclass. Circumscription of the subclass will vary with the taxonomic system being used (there are many such systems); the only requirement being that it includes the family Liliaceae. Liliidae in Takhtajan system The Takhtajan system treats this as one of six subclasses within class Liliopsida (= monocotyledons). This subclass consists of: * subclass Liliidae *: superorder Lilianae *:: order Melanthiales *:: order Colchicales *:: order Trilliales *:: order Liliales *:: order Alstroemeriales *:: order Iridales *:: order Tecophilaeales *:: order Burmanniales *:: order Hypoxidales *:: order Orchidales *:: order Amaryllidales *:: order Asparagales *:: order Xanthorrhoeales *:: order Hanguanales *: superorder Dioscoreanae *:: order Stemonales *:: order Smilacales *:: order Dioscoreales *:: order Taccales Liliidae in Cronquist system The Cronquist system treats this as one of five subclasses within class Liliopsida (= monoco ...

Descriptive Botanical Name
Descriptive botanical names are scientific names of groups of plants that are irregular, not being derived systematically from the name of a type genus. They may describe some characteristics of the group in general or may be a name already in existence before regularised scientific nomenclature. Descriptive names can occur above or at the rank of family. There is only a single descriptive below the rank of family (the subfamily Papilionoideae). Above the rank of family Descriptive names above the rank of family are governed by Article 16 of the International Code of Nomenclature for algae, fungi, and plants (ICN), which rules that a name above the rank of family may either be ‘automatically typified’ (such as Magnoliophyta and Magnoliopsida from the type genus ''Magnolia'') or be descriptive. Descriptive names of this type may be used unchanged at different ranks (without modifying the suffix). These descriptive plant names are decreasing in importance, becoming less common ...

Botanical Nomenclature
Botanical nomenclature is the formal, scientific naming of plants. It is related to, but distinct from taxonomy (biology), taxonomy. Plant taxonomy is concerned with grouping and classifying plants; Botany, botanical nomenclature then provides names for the results of this process. The starting point for modern botanical nomenclature is Carl Linnaeus, Linnaeus' ''Species Plantarum'' of 1753. Botanical nomenclature is governed by the ''International Code of Nomenclature for algae, fungi, and plants'' (''ICNafp''), which replaces the ''International Code of Botanical Nomenclature'' (''ICBN''). Fossil plants are also covered by the code of nomenclature. Within the limits set by that code there is another set of rules, the ''International Code of Nomenclature for Cultivated Plants, International Code of Nomenclature for Cultivated Plants (ICNCP)'' which applies to plant cultivars that have been deliberately altered or selected by humans (see cultigen). Botanical nomenclature is indep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ICBN
The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN or ICNafp) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those "traditionally treated as algae, fungi, or plants".. It was formerly called the ''International Code of Botanical Nomenclature'' (ICBN); the name was changed at the International Botanical Congress in Melbourne in July 2011 as part of the ''Melbourne Code''. which replaced the ''Vienna Code'' of 2005. The current version of the code is the ''Shenzhen Code'' adopted by the International Botanical Congress held in Shenzhen, China, in July 2017. As with previous codes, it took effect as soon as it was ratified by the congress (on 29 July 2017), but the documentation of the code in its final form was not published until 26 June 2018. For fungi the ''Code'' was revised by the ''San Juan Chapter F'' in 2018. The 2025 edition of ICBN, the ''Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kubitzki System
The Kubitzki system is a system of plant taxonomy devised by Klaus Kubitzki, and is the product of an ongoing survey of vascular plants, entitled ''The Families and Genera of Vascular Plants'', and extending to 15 volumes in 2018. The survey, in the form of an encyclopedia, is important as a comprehensive, multivolume treatment of the vascular plants, with keys to and descriptions of all families and genera, mostly by specialists in those groups. The Kubitzki system served as the basis for classification in ''Mabberley's Plant-Book'', a dictionary of the vascular plants. Mabberley states, in his Introduction on page xi of the 2008 edition, that the Kubitzki system "has remained the standard to which other literature is compared". In ordinal and family arrangements, the classification system in the initial angiosperm volumes closely resembles the Dahlgren system in Monocots and the Cronquist system in Dicots, but later volumes have been influenced by recent molecular phylogene ...

Monocotyledones
Monocotyledons (), commonly referred to as monocots, ( Lilianae ''sensu'' Chase & Reveal) are flowering plants whose seeds contain only one embryonic leaf, or cotyledon. A monocot taxon has been in use for several decades, but with various ranks and under several different names. The APG IV system recognises its monophyly but does not assign it to a taxonomic rank, and instead uses the term "monocots" to refer to the group. Monocotyledons are contrasted with the dicotyledons, which have two cotyledons. Unlike the monocots however, the dicots are not monophyletic and the two cotyledons are instead the ancestral characteristic of all flowering plants. Botanists now classify dicots into the eudicots ("true dicots") and several basal lineages from which the monocots emerged. The monocots are extremely important economically, culturally, and ecologically, and make up a majority of plant biomass used in agriculture. Common crops such as dates, onions, garlic, rice, wheat, maize, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engler System
One of the prime systems of plant taxonomy, the Engler system was devised by Adolf Engler (1844–1930), and is featured in two major taxonomic texts he authored or co-authored. His influence is reflected in the use of the terms "Engler School" and "Engler Era". Engler's starting point was that of Eichler who had been the first to use phylogenetic principles, although Engler himself did not think that he was. Engler's works His modified Eichler schema first appeared in 1886 in his ''Guide to Breslau Botanic Garden'' (of which he was the director) and was expanded in his '' Syllabus der Pflanzenfamilien'' in 1892. This reflected the new post- Darwinian perspective. Engler's ''Syllabus'' first appeared in 1892 with the title ''Syllabus der Vorlesungen über specielle und medicinisch-pharmaceutische Botanik''. Many subsequent editions have appeared since, and it was continued after Engler's death in 1930. The most recent edition was the 13th in 2009. The other major work was '' Die ...

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 cultivar group, 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, Fungus, fungi, or plants, whether fossil or non-fossil, including blue-green algae (Cyanobacteria), Chytridiomycota, chytrids, oomycetes, slime moulds and Photosynthesis, 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 variou ...

Plant Taxonomy
Plant taxonomy is the science that finds, identifies, describes, classifies, and names plants. It is one of the main branches of taxonomy (the science that finds, describes, classifies, and names living things). Plant taxonomy is closely allied to plant systematics, and there is no sharp boundary between the two. In practice, "plant systematics" involves relationships between plants and their evolution, especially at the higher levels, whereas "plant taxonomy" deals with the actual handling of plant specimens. The precise relationship between taxonomy and systematics, however, has changed along with the goals and methods employed. Plant taxonomy is well known for being turbulent, and traditionally not having any close agreement on circumscription and placement of taxa. See the list of systems of plant taxonomy. Background Classification systems serve the purpose of grouping organisms by characteristics common to each group. Plants are distinguished from animals by various ...

APG System
The APG system (Angiosperm Phylogeny Group system) of plant classification is the first version of a modern, mostly molecular-based, system of plant taxonomy. Published in 1998 by the Angiosperm Phylogeny Group, it was replaced by the improved APG II in 2003, APG III system in 2009 and APG IV system in 2016. History The original APG system is unusual in being based, not on total evidence, but on the cladistic analysis of the DNA sequences of three genes, two chloroplast genes and one gene coding for ribosomes. Although based on molecular evidence only, its constituent groups prove to be supported by other evidence as well, for example pollen morphology supports the split between the eudicots and the rest of the former dicotyledons. The system is rather controversial in its decisions at the family level, splitting a number of long-established families and submerging some other families. It also is unusual in not using botanical names above the level of order, that is, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palmae
The Arecaceae () is a family of perennial, flowering plants in the monocot order Arecales. Their growth form can be climbers, shrubs, tree-like and stemless plants, all commonly known as palms. Those having a tree-like form are colloquially called palm trees. Currently, 181 genera with around 2,600 species are known, most of which are restricted to tropical and subtropical climates. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, arranged at the top of an unbranched stem, except for the Hyphaene genus, who has branched palms. However, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of habitat within their range, from rainforests to deserts. Palms are among the best known and most extensively cultivated plant families. They have been important to humans throughout much of history, especially in regions like the Middle East and North Africa. A wide range of common products and foods are de ...
