Zygophyllales Genera
The Zygophyllales are an order of dicotyledonous plants, comprising the following two families: * Family Zygophyllaceae * Family Krameriaceae According to the Angiosperm Phylogeny Group (APG II) both families are unplaced to order, but nevertheless included in the Eurosids I. The APG III system of 2009, however, recognized this order. Even if the monogeneric family Krameriaceae shares few common traits with the family Zygophyllaceae, researchers see little advantage in keeping it as a separate family (e.g. Sheahan and Chase). The name Zygophyllales can be used if one finds it appropriate to place both families into an order. The order remains unchanged in the APG IV system. Under the Cronquist system, the Zygophyllaceae were included within the Sapindales, and the Krameriaceae within the Polygalales Fabales is an order of flowering plants included in the rosid group of the eudicots in the Angiosperm Phylogeny Group II classification system. In the APG II circumscription, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Heinrich Friedrich Link
Johann Heinrich Friedrich Link (2 February 1767 – 1 January 1851) was a German natural history, naturalist and botanist. Biography Link was born at Hildesheim as a son of the minister August Heinrich Link (1738–1783), who taught him love of nature through collection of 'natural objects'. He studied medicine and natural sciences at the Hannoverschen Landesuniversität of Göttingen, and graduated as MD in 1789, promoting on his thesis ''"Flora der Felsgesteine rund um Göttingen"'' (Flora of the rocky beds around Göttingen). One of his teachers was the famous natural scientist Johann Friedrich Blumenbach (1752–1840). He became a private tutor (''Privatdozent'') in Göttingen. In 1792, he became the first professor of the new department of chemistry, zoology and botany at the University of Rostock. During his stay at Rostock, he became an early follower of the antiphlogistic theory of Lavoisier, teaching about the existence of oxygen instead of phlogiston. He was also a p ...

Type Genus
In biological taxonomy, the type genus (''genus typica'') is the genus which defines a biological family and the root of the family name. Zoological nomenclature According to the International Code of Zoological Nomenclature, "The name-bearing type of a nominal family-group taxon is a nominal genus called the 'type genus'; the family-group name is based upon that of the type genus." Any family-group name must have a type genus (and any genus-group name must have a type species, but any species-group name may, but need not, have one or more type specimens). The type genus for a family-group name is also the genus that provided the stem to which was added the ending -idae (for families). :Example: The family name Formicidae has as its type genus the genus ''Formica'' Linnaeus, 1758. Botanical nomenclature In botanical nomenclature, the phrase "type genus" is used, unofficially, as a term of convenience. In the '' ICN'' this phrase has no status. The code uses type specimens ...

Zygophyllum
''Zygophyllum'' is the type genus of the flowering plant family Zygophyllaceae. The generic name is derived from the Greek language, Greek words ζυγόν (''zygon''), meaning "double", and φυλλον (''phyllon''), meaning "leaf". It refers to the leaves, each of which have two leaflet (botany), leaflets. The genus is distributed in arid and Semi-arid climate, semi-arid regions of Africa, the Mediterranean Basin, central Asia, Australia, and North and South America. Molecular phylogenetics, Molecular phylogenetic analysis suggested that as previously Circumscription (taxonomy), circumscribed, ''Zygophyllum'' was not Monophyly, monophyletic, and the genus was split among a number of other genera, including ''Augea (plant), Augea'', ''Fagonia'', ''Roepera'' and ''Tetraena''. , Plants of the World Online accepted only ''Roepera'' of these genera, regarding ''Augea'', ''Fagonia'' and ''Tetraena'' as synonyms of ''Zygophyllum''.

Astringent
An astringent (sometimes called adstringent) is a chemical that shrinks or constricts body tissues. The word derives from the Latin '' adstringere'', which means "to bind fast". Astringency, the dry, puckering or numbing mouthfeel caused by the tannins in unripe fruits, lets the fruit mature by deterring eating. Tannins, being a kind of polyphenol, bind salivary proteins and make them precipitate and aggregate, producing a rough, "sandpapery", or dry sensation in the mouth. Smoking tobacco is also reported to have an astringent effect. In a scientific study, astringency was still detectable by subjects who had local anesthesia applied to their taste nerves, but not when both these and the trigeminal nerves were disabled. Uses In medicine, astringents cause constriction or contraction of mucous membranes and exposed tissues and are often used internally to reduce discharge of blood serum and mucous secretions. This can happen with a sore throat, hemorrhages, diarrhe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Krameria Triandra
''Krameria lappacea'', commonly known as para rhatany and Peruvian rhatany, is a plant species in the genus ''Krameria'', native to Ecuador, Peru, Bolivia, northern Chile and northwest Argentina. It is a slow-growing shrub that grows in semi-arid areas of the Andean region. The Latin specific epithet In Taxonomy (biology), taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin gramm ... of ''lappacea'' is derived from ''lappa'' meaning with burrs.

Parasitic Plant
A parasitic plant is a plant that derives some or all of its nutritional requirements from another living plant. They make up about 1% of angiosperms and are found in almost every biome. All Parasite, parasitic plants develop a specialized organ called the haustorium, which penetrates the host plant, connecting them to the host vasculature—either the xylem, phloem, or both. For example, plants like ''Striga'' or ''Rhinanthus'' connect only to the xylem, via xylem bridges (xylem-feeding). Alternately, plants like ''Cuscuta'' and some members of ''Orobanche'' connect to both the xylem and phloem of the host. This provides them with the ability to extract resources from the host. These resources can include water, nitrogen, carbon and/or sugars. Parasitic plants are classified depending on the location where the parasitic plant latches onto the host (root or stem), the amount of nutrients it requires, and their photosynthetic capability. Some parasitic plants can locate their host ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilhelm Heinrich Kramer
Wilhelm Heinrich Kramer (1724 in Dresden – 13 October 1765) was a German physician and naturalist. Kramer studied in Vienna, Austria, then practiced medicine in Bruck, close to the capital, for at least 14 years. He published in 1756 a work entitled ''Elenchus Vegetabilium and Animalium per Austriam inferiorem Observatorum'', a flora and fauna of Lower Austria noted especially because it was one of the first works to adopt the binomial nomenclature of Carl von Linné (1707–1778). In it, he created the name ''pratincola'' for the collared pratincole which was adapted in English in the following work of Thomas Pennant (1726–1798) in 1773. It is probably for him that Giovanni Antonio Scopoli (1723–1788) dedicated ''Psittacus krameri'' (today ''Psittacula krameri'') in 1769. He was also an entomologist Entomology (from Ancient Greek ἔντομον (''éntomon''), meaning "insect", and -logy from λόγος (''lógos''), meaning "study") is the branch of zoology that focu ...

Krameria
''Krameria'' is the only genus in the Krameriaceae family, of which any of the approximately 18 species are commonly known as rhatany, ratany or rattany. Rhatany is also the name given to krameria root, a botanical remedy consisting of the dried root of para rhatany (''Krameria argentea'') or Peruvian rhatany (''Krameria lappacea''). The biological action of rhatany is caused by the astringent rhataniatannic acid, which is similar to tannic acid. Infusions have been used as a gargle, a lozenge, especially when mixed with cocaine, as a local Antihemorrhagic, hemostatic and remedy for diarrhea. When finely powdered, the dried roots furnished a frequent constituent of Dentifrice, tooth powders. The powdered roots have also served, especially in Portuguese wine, Portugal, to color wines ruby red. The root bark contains an almost insoluble free red substance called ratanhia red. Ecology ''Krameria'' are found across the Americas where they grow in habitats ranging from arid deserts t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Etymology
Etymology ( ) is the study of the origin and evolution of words—including their constituent units of sound and meaning—across time. In the 21st century a subfield within linguistics, etymology has become a more rigorously scientific study. Most directly tied to historical linguistics, philology, and semiotics, it additionally draws upon comparative semantics, morphology, pragmatics, and phonetics in order to attempt a comprehensive and chronological catalogue of all meanings and changes that a word (and its related parts) carries throughout its history. The origin of any particular word is also known as its ''etymology''. For languages with a long written history, etymologists make use of texts, particularly texts about the language itself, to gather knowledge about how words were used during earlier periods, how they developed in meaning and form, or when and how they entered the language. Etymologists also apply the methods of comparative linguistics to reconstruct in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is often based in Latin. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including s ...

Zygophyllaceae
Zygophyllaceae is a family of flowering plants that contains the bean-caper and caltrop. The family includes around 285 species in 22 genera. Plants in the family Zygophyllaceae may be trees, shrubs, or herbs. They are often found in dry habitats. The leaves are usually opposite, often with stipules and spines. Some are cultivated as ornamental plants, such as species of the '' Guaiacum'', ''Zygophyllum'', '' Tribulus'', and '' Larrea'' genera. King Clone, a creosote bush ''(Larrea tridentata)'' in California, is among the world's oldest living organisms. The distribution of plants in the Zygophyllaceae family can be found worldwide in warm tropics and cool-temperate subtropics with a concentration in hot, arid regions with alkaline soils. Regions with different species from this family include Africa, south Asia, India, Australia and parts of the United States. Genera '' Peganum'' was in Zygophyllaceae before being moved to the newly created family Nitrariaceae. Systema ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
