Coriaria
''Coriaria'' is the sole genus in the family Coriariaceae, which was described by Linnaeus in 1753. It includes 14 species of small trees, shrubs and subshrubs, with a widespread but disjunct distribution across warm temperate regions of the world, occurring as far apart as the Mediterranean region, southern and eastern Asia, New Zealand (where some are alpine species), the Pacific Ocean islands, and Central and South America. The leaves are opposite or in whorls, simple, long, without stipules. The flowers are borne in racemes 2–30 cm long, each flower small, greenish, with five small petals. The fruit is a small and shiny black (occasionally yellow or red) berry-like swollen corolla, highly poisonous in several species, though those of ''C. terminalis'' are edible. At least a few members of this genus are non-legume nitrogen fixers. The Mediterranean species ''C. myrtifolia'' is known as redoul, and the several New Zealand species are known by the Māori name of tutu. ...

Coriaria Arborea
''Coriaria arborea'' is a highly poisonous and common native shrub or small tree of New Zealand. The common name for the plant is tree tutu'', and it is one of the New Zealand species of ''Coriaria'' known by the name tutu. ''Coriaria arborea'' is found in scrub and open areas from the coast to the hills across the country. A straggling plant, it can grow to high. The leaves grow opposite on slender stems while flowers are arranged in drooping racemes. ''C. arborea'' is capable of nitrogen fixation Nitrogen fixation is a chemical process by which molecular dinitrogen () is converted into ammonia (). It occurs both biologically and abiological nitrogen fixation, abiologically in chemical industry, chemical industries. Biological nitrogen .... Description ''Coriaria arborea'' is a large shrub that grows pairs of long, glossy leaves on branches, which measure between long. It has flowers that droop from spikes of up to in length, with black-coloured fruits. Taxonomy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tutu (plant)
Tutu is a common name of Māori origin for plants in the genus '' Coriaria'' found in New Zealand. Name The Māori language name tutu has cognates found in other Eastern Polynesian languages such as Tahitian and Cook Islands Māori which use the word to describe ''Colubrina asiatica'', a plant that has visual similarity to ''Coriaria''. Tutu is also colloquially known as toot in New Zealand. Taxonomy Eight New Zealand native species are known by the name: * '' Coriaria angustissima'' * ''Coriaria arborea'' * ''Coriaria kingiana'' * '' Coriaria lurida'' * '' Coriaria plumosa'' * '' Coriaria pottsiana'' * '' Coriaria pteridoides'' * '' Coriaria sarmentosa'' Description They are shrubs or trees; some are endemic to New Zealand. Most of the plant parts are poisonous, containing the neurotoxin tutin and its derivative hyenanchin. Toxicity The widespread species ''Coriaria arborea'' is most often linked to cases of poisoning. Most of the plant except for the flesh of the fru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coriaria Ruscifolia
''Coriaria ruscifolia'' is a plant of the Coriariaceae family. It is native to Mexico, Central America, and South America. Description ''Coriaria ruscifolia'' is a deciduous shrub. It is poisonous except for the "fruit", which are actually petals. Uses In Ecuador, its fruits are reportedly eaten to produce an inebriated state. The eater is said to experience “sensations of soaring through the air”. The effects are said to be similar to those produced by ''Petunia violacea''. ''Coriaria ruscifolia'' grows in Mexico as well; it has been suggested that it was the Aztec inebriant known as tlacopétatl. In the Las Huaringas region, a lake plateau in the northern Peruvian Andes, the local healers (curanderos) refer to ''Coriaria ruscifolia'' as contra-alergica, “against allergies.” They use the herbage to prepare a bath additive that they use to wash patients suffering from allergic reactions. Toxicity The fruits contain catechol derivatives and probably several sesquiterpe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Non-legume Nitrogen Fixer
Actinorhizal plants are a group of angiosperms characterized by their ability to form a symbiosis with the nitrogen fixing actinomycetota ''Frankia''. This association leads to the formation of nitrogen-fixing root nodules. Actinorhizal plants are distributed within three clades, and are characterized by nitrogen fixation. They are distributed globally, and are pioneer species in nitrogen-poor environments. Their symbiotic relationships with Frankia evolved independently over time, and the symbiosis occurs in the root nodule infection site. Classification Actinorhizal plants are dicotyledons distributed within 3 orders, 8 families and 26 genera, of the angiosperm clade. All nitrogen fixing plants are classified under the "Nitrogen-Fixing Clade", which consists of the three actinorhizal plant orders, as well as the order fabales. The most well-known nitrogen fixing plants are the legumes, but they are not classified as actinorhizal plants. The actinorhizal species are either tree ...

Kermadec Islands
The Kermadec Islands ( ; ) are a subtropical island arc in the South Pacific Ocean northeast of New Zealand's North Island, and a similar distance southwest of Tonga. The islands are part of New Zealand. They are in total area and uninhabited, except for the permanently staffed Raoul Island Station, the northernmost outpost of New Zealand. The islands are listed with the New Zealand outlying islands. The islands are an immediate part of New Zealand, but not part of any region or district, but instead an ''Area Outside Territorial Authority''. Toponymy The islands were named after the Breton captain Jean-Michel Huon de Kermadec, who visited the islands as part of the d'Entrecasteaux expedition in the 1790s. The topographic particle "Kermadec" is of Breton origin and is a lieu-dit in Pencran in Finistère where '' ker'' means village, residence and ''madec'' a proper name derived from '' mad'' (which means 'good') with the suffix '' -ec'', used to form adjectives indicati ...

New Zealand
New Zealand () is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and List of islands of New Zealand, over 600 smaller islands. It is the List of island countries, sixth-largest island country by area and lies east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The Geography of New Zealand, country's varied topography and sharp mountain peaks, including the Southern Alps (), owe much to tectonic uplift and volcanic eruptions. Capital of New Zealand, New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and subsequently developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
