Shanyao Steet
''Dioscorea polystachya'' or Chinese yam ( zh, s=山药, t=山藥), also called cinnamon-vine, is a species of flowering plant in the yam family. It is sometimes called Chinese potato or by its Korean name ''ma''. It is a perennial climbing vine, native to East Asia. The edible tubers are cultivated largely in Asia and sometimes used in alternative medicine. This species of yam is unique as the tubers can be eaten raw. Range This plant grows throughout East Asia. It is believed to have been introduced to Japan in the 17th century or earlier. Introduced to the United States as early as the 19th century for culinary and cultural uses, it is now considered an invasive plant species. The plant was introduced to Europe in the 19th century during the European Potato Failure, where cultivation continues to this day for the Asian food market. Taxonomy The botanical names ''Dioscorea opposita'' and '' Dioscorea oppositifolia'' have been consistently misapplied to Chinese yam. ...

Nikolai Turczaninow
Nikolai Stepanovich Turczaninow ( ru , Николай Степанович Турчанинов, 1796 in Nikitovka, now in Krasnogvardeysky District, Belgorod Oblast, Russia – 1863 in Kharkov) was a Russian botanist and plant collector who first identified several genera, and many species, of plants. Education and career Born in 1796, Turczaninow attended high school in Kharkov. In 1814, he graduated from Kharkov University, before working as a civil servant for the Ministry of Finance in St. Petersburg. Soon after, in 1825, Turczaninow published his first botanical list. Despite being employed in a different field, he continued his largely self-taught botanical work. In 1828, he was assigned an administrative post in Irkutsk, Siberia. This allowed him to collect in the Lake Baikal area, which is known for its rich biodiversity. A spate of papers followed, and Turczaninow established his own herbarium containing plants from the region. In 1830, he was appointed a Fellow o ...

European Potato Failure
The European Potato Failure was a food crisis caused by potato blight that struck Northern and Western Europe in the mid-1840s. The time is also known as the Hungry Forties. While the crisis produced excess mortality and suffering across the affected areas, particularly affected were the Scottish Highlands and, even more harshly, Ireland. Many people starved due to lack of access to other staple food sources. Potatoes at the time In 2013, researchers analysed biological collections in museums with DNA sequencing techniques to decode DNA from the pathogen in stored samples from 1845 and compare them to modern genetic types. The results indicated the "strain was different from all the modern strains analysed". After the blight, strains originating in the Chiloé Archipelago replaced earlier potatoes of Peruvian origin in Europe. Population decline The effect of the crisis on Ireland is incomparable to all other places, causing one million deaths, up to two million refugee ...

Ginkgo
''Ginkgo'' is a genus of non-flowering seed plants. The scientific name is also used as the English name. The order to which it belongs, Ginkgoales, first appeared in the Permian, 270 million years ago, and is now the only living genus within the order. The rate of evolution within the genus has been slow, and almost all its species had become extinct by the end of the Pliocene. The sole surviving species, ''Ginkgo biloba'' is only found in the wild in China, but is cultivated around the world. The relationships between ginkgos and other groups of plants are not fully resolved. Prehistory The ginkgo (''Ginkgo biloba'') is a living fossil, with fossils similar to the modern plant dating back to the Permian, 270 million years ago. The closest living relatives of the clade are the cycads, which share with the extant ''G. biloba'' the characteristic of motile sperm. The ginkgo and cycad lineages are thought to have an extremely ancient divergence dating to the early Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dioscorea Polystachya UGA5421977
''Dioscorea'' is a genus of over 600 species of flowering plants in the family Dioscoreaceae, native throughout the tropical and warm temperate regions of the world. The vast majority of the species are tropical, with only a few species extending into temperate climates. It was named by the monk Charles Plumier after the ancient Greek physician and botanist Dioscorides. Description Wild Yam (''Dioscorea'') is a vine that is invasive, deciduous, and herbaceous. This species is native to Asia, though, in the U.S., it is commonly found in Florida. They can grow over in length. Wild yams are an important crop, as they have been used to prevent menstrual cramps, stomach cramps, and general pain for centuries. During the 1950s scientists found that the roots of wild yams contained diosgenin which is a plant-based estrogen; diosgenin is hypothesized to aid in chemical defense against herbivores. This was used to create the first birth control pills during the 60s. In addition, some '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cinnamon
Cinnamon is a spice obtained from the inner bark of several tree species from the genus ''Cinnamomum''. Cinnamon is used mainly as an aromatic condiment and flavouring additive in a wide variety of cuisines, sweet and savoury dishes, breakfast cereals, snack foods, bagels, teas, and traditional foods. The aroma and flavour of cinnamon derive from its essential oil and principal component, cinnamaldehyde, as well as numerous other constituents including eugenol. Cinnamon is the name for several species of trees and the commercial spice products that some of them produce. All are members of the genus ''Cinnamomum'' in the family Lauraceae. Only a few ''Cinnamomum'' species are grown commercially for spice. ''Cinnamomum verum'' (AKA ''C. zeylanicum''), known as "Ceylon cinnamon" after its origins in Sri Lanka (formerly Ceylon), is considered to be "true cinnamon", but most cinnamon in international commerce is derived from four other species, usually and more correctly refe ...

Bulbil
A bulbil (also referred to as bulbel, bulblet, and/or pup) is a small, young plant that is reproduced vegetatively from axillary buds on the parent plant's stem or in place of a flower on an inflorescence. These young plants are clones of the parent plant that produced them—they have identical genetic material. The formation of bulbils is a form of asexual reproduction, as they can eventually go on to form new stand-alone plants. Although some bulbils meet the botanical criterion to be considered a true bulb, there are a variety of different morphological forms of bulbils, some of which are not considered to be bulbs. Hence the reason for distinction between bulbs and bulbils. For example, some bulbous plant groups, like onions and lilies, produce bulbils in the form of a secondary, small bulb. Onion and lily bulbils meet the botanical criterion to be labeled a true bulb. All bulbils produced by bulbous plants are to be considered bulbs, but not all bulbils are to be consid ...

Auctorum
Auctorum indicates that a name in botany and zoology is used in the sense of subsequent authors, and not in the sense as established by the original author. Its etymology derives from the Latin word for ''of authors'', and is abbreviated auct. or auctt. Some species names have been used twice for different species so the author of the name needs to be identified. For example "''Leucospermum bolusii'' auct. Gandoger" for the species that was named as such by Gandoger. It is often used in conjunction with nec or non to indicate a misapplied name, e.g. "''Leucospermum bolusii'' auct. non Gandoger" would mean the species not named by Gandoger. It may be qualified to indicate the number of authors, e.g. auctorum multorum (abbreviated auct. mult.), Latin for ''of many authors'', indicating that many subsequent authors used a name in a different sense to the original author, and also by non to give auctorum non (auct. non), to indicate that a following author is not the author of the spe ...
