Pachyrhizus Erosus 2
''Pachyrhizus'' is a small genus of five or six species of tropical and subtropical plants growing from large, often edible taproots. Jícama The jícama or yam bean (''P. erosus'') is a vine widely grown for its large (10–15 cm diameter and up to 20 kg weight), spherical or elongated taproot. After removal of the thick, fibrous brown skin, the white flesh of the root can be eaten cooked or raw. Crisp, moist, and slightly sweet, the flesh draws comparison with that of the apple. The plant produces seeds that are comparable to lima beans, and that are sometimes eaten when young in places where the jicama is native. The mature seeds contain high levels of rotenone, a chemical used as an insecticide and pesticide. The remainder of the jícama plant is very poisonous. Jícama comes from the New World; the name jícama is used in Central / South America. Today, pachyrhizus erosus is grown throughout Asia. In China, the root is known as cold potato; in Malaysia, sen ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Louis Claude Richard
Louis Claude Marie Richard (19 September 1754 – 6 June 1821) was a French botanist and botanical illustrator. Richard was born at Versailles. Between 1781 and 1789 he collected botanical specimens in Central America and the West Indies. On his return he became a professor at the École de médecine in Paris. His books included ''Demonstrations botaniques'' (1808), ''De Orchideis europaeis'' (1817), ''Commentatio botanica de Conifereis et Cycadeis'' (1826) and ''De Musaceis commentatio botanica'' (1831). He gave us the special description terminology for the orchids, such as pollinium and gynostemium. The genus ''Richardia'' Kunth, (Araceae) was named in his honor. It is now a synonym of the genus ''Zantedeschia'' . This botanist is denoted by the author abbreviation when citing a botanical name. His son was another notable botanist, Achille Richard. He also discovered Morgat in the 1880s. Eponyms A species of Caribbean lizard, ''Anolis richardii'', is named in honor of ...

Poison
Poison is a chemical substance that has a detrimental effect to life. The term is used in a wide range of scientific fields and industries, where it is often specifically defined. It may also be applied colloquially or figuratively, with a broad sense. Whether something is considered a poison may change depending on the amount, the circumstances, and what living things are present. Poisoning could be accidental or deliberate, and if the cause can be identified there may be ways to neutralise the effects or minimise the symptoms. In biology, a poison is a chemical substance causing death, injury or harm to organisms or their parts. In medicine, poisons are a kind of toxin that are delivered passively, not actively. In industry the term may be negative, something to be removed to make a thing safe, or positive, an agent to limit unwanted pests. In ecological terms, poisons introduced into the environment can later cause unwanted effects elsewhere, or in other parts of the food ...

Phaseoleae
The plant tribe Phaseoleae is one of the subdivisions of the legume subfamily Faboideae, in the unranked NPAAA clade. This group includes many of the beans cultivated for human and animal food, most importantly from the genera ''Glycine'', '' Phaseolus'', and ''Vigna''. Taxonomy Although the tribe as defined in the late 20th century does not appear to be monophyletic, there does seem to be a monophyletic group which roughly corresponds to the tribe Phaseoleae (with some changes). The earlier concept of Phaseoleae is paraphyletic relative to the tribes Abreae and Psoraleeae, plus most of Millettieae and parts of Desmodieae.

Integrated Taxonomic Information System
The Integrated Taxonomic Information System (ITIS) is an American partnership of federal agencies designed to provide consistent and reliable information on the taxonomy of biological species. ITIS was originally formed in 1996 as an interagency group within the US federal government, involving several US federal agencies, and has now become an international body, with Canadian and Mexican government agencies participating. The database draws from a large community of taxonomic experts. Primary content staff are housed at the Smithsonian National Museum of Natural History and IT services are provided by a US Geological Survey facility in Denver. The primary focus of ITIS is North American species, but many biological groups exist worldwide and ITIS collaborates with other agencies to increase its global coverage. Reference database ITIS provides an automated reference database of scientific and common names for species. As of May 2016, it contains over 839,000 scientific names, ...

West Indies
The West Indies is a subregion of North America, surrounded by the North Atlantic Ocean and the Caribbean Sea that includes 13 independent island countries and 18 dependencies and other territories in three major archipelagos: the Greater Antilles, the Lesser Antilles, and the Lucayan Archipelago. The subregion includes all the islands in the Antilles, plus The Bahamas and the Turks and Caicos Islands, which are in the North Atlantic Ocean. Nowadays, the term West Indies is often interchangeable with the term Caribbean, although the latter may also include some Central and South American mainland nations which have Caribbean coastlines, such as Belize, French Guiana, Guyana, and Suriname, as well as the Atlantic island nations of Barbados, Bermuda, and Trinidad and Tobago, all of which are geographically distinct from the three main island groups, but culturally related. Origin and use of the term In 1492, Christopher Columbus became the first European to record his arri ...

Andes
The Andes, Andes Mountains or Andean Mountains (; ) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long, wide (widest between 18°S – 20°S latitude), and has an average height of about . The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. Along their length, the Andes are split into several ranges, separated by intermediate depressions. The Andes are the location of several high plateaus—some of which host major cities such as Quito, Bogotá, Cali, Arequipa, Medellín, Bucaramanga, Sucre, Mérida, El Alto and La Paz. The Altiplano plateau is the world's second-highest after the Tibetan plateau. These ranges are in turn grouped into three major divisions based on climate: the Tropical Andes, the Dry Andes, and the Wet Andes. The Andes Mountains are the highest m ...

Rotenone
Rotenone is an odorless, colorless, crystalline isoflavone used as a broad-spectrum insecticide, piscicide, and pesticide. It occurs naturally in the seeds and stems of several plants, such as the jicama vine plant, and the roots of several members of Fabaceae. It was the first described member of the family of chemical compounds known as rotenoids. Discovery The earliest record of the now-known rotenone-containing plants used for killing leaf-eating caterpillars was in 1848, and for centuries, the same plants were used to poison fish. The active chemical component was first isolated in 1895 by a French botanist, Emmanuel Geoffroy, who called it ''nicouline'', from a specimen of ''Robinia nicou'', now called ''Lonchocarpus nicou'', while traveling in French Guiana. He wrote about this research in his thesis, published in 1895 after his death from a parasitic disease. In 1902 Kazuo Nagai, Japanese chemical engineer of the Government-General of Taiwan, isolated a pure crystalline ...

Lima Bean
A lima bean (''Phaseolus lunatus''), also commonly known as the butter bean, sieva bean, double bean, Madagascar bean, or wax bean is a legume grown for its edible seeds or beans. Origin and uses ''Phaseolus lunatus'' is found in Meso- and South America. Two gene pools of cultivated lima beans point to independent domestication events. The Mesoamerican lima bean is distributed in neotropical lowlands, while the other is found in the western Andes. They were discovered in Peru and may have been the first plant that was brought up under civilization by the native farmers. The Andes domestication took place around 2000 BC and produced a large-seeded variety (lima type), while the second, taking place in Mesoamerica around 800 AD, produced a small-seeded variety (Sieva type). By around 1300, cultivation had spread north of the Rio Grande, and, in the 1500s, the plant began to be cultivated in the Old World. The small-seeded (Sieva) type is found distributed from Mexico to Argent ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
