Purple Yam
''Dioscorea alata'', also known as purple yam, ube (, ), or greater yam, among many other names, is a species of yam (a tuber). The tubers are usually a vivid violet-purple to bright lavender in color (hence the common name), but some range in color from cream to plain white. It is sometimes confused with taro and the Okinawa sweet potato (''Ipomoea batatas'' cv. Ayamurasaki), although ''D. alata'' is also grown in Okinawa, where it is known as . With its origins in the Asian tropics, ''D. alata'' has been known to humans since ancient times. Names Because it has become naturalized following its origins in Asia, specifically the Philippines, through tropical South America, and the southeastern U.S., ''D. alata'' is referred to by many different names in these regions. In English alone, aside from purple yam, other common names include ten-months yam, water yam, white yam, winged yam, violet yam, Guyana arrowroot, or simply yam.

Pacific Islands
Collectively called the Pacific Islands, the islands in the Pacific Ocean are further categorized into three major island groups: Melanesia, Micronesia, and Polynesia. Depending on the context, the term ''Pacific Islands'' may refer to one of several different concepts: (1) those countries and islands with common Austronesian origins, (2) the islands once (or currently) colonized, or (3) the geographical region of Oceania. This list of islands in the Pacific Ocean is organized by archipelago or border, political boundary. In order to keep this list of moderate size, the more complete lists for countries with large numbers of small or uninhabited islands have been hyperlinked. Name ambiguity and groupings The umbrella term ''Pacific Islands'' has taken on several meanings. Sometimes it is used to refer only to the islands defined as lying within Oceania Oceania (, , ) is a region, geographical region that includes Australasia, Melanesia, Micronesia, and Polynesia.

Austronesian Expansion
The Austronesian peoples, sometimes referred to as Austronesian-speaking peoples, are a large group of peoples in Taiwan, Maritime Southeast Asia, Micronesia, coastal New Guinea, Island Melanesia, Polynesia, and Madagascar that speak Austronesian languages. They also include indigenous ethnic minorities in Vietnam, Cambodia, Myanmar, Thailand, Hainan, the Comoros, and the Torres Strait Islands. The nations and territories predominantly populated by Austronesian-speaking peoples are sometimes known collectively as Austronesia. Based on the current scientific consensus, they originated from a prehistoric seaborne migration, known as the Austronesian expansion, from pre- Han Taiwan, at around 1500 to 1000 BCE. Austronesians reached the northernmost Philippines, specifically the Batanes Islands, by around 2200 BCE. Austronesians used sails some time before 2000 BCE. In conjunction with their use of other maritime technologies (notably catamarans, outrigger boats, lashed- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dioscorine
Dioscorine is an alkaloid toxin isolated from the tubers of tropical yam on several continents. It has been used as a monkey poison in some African countries, and as an arrow poison to aid in hunting in several parts of Asia. It was first isolated from '' Dioscorea hirsute'' (synonymous with ''Dioscorea hirsuta'') by Boorsma in 1894 and obtained in a crystalline form by Schutte in 1897, and has since been found in other ''Dioscorea'' species. Dioscorine is a neurotoxin that acts by blocking the nicotinic acetylcholine receptor. Dioscorine is generally isolated in tandem with other alkaloids such as dioscin but is usually the most potent toxin in the mixture. It is a convulsant, producing symptoms similar to picrotoxin, with which it shares a similar mechanism of action. (Dioscorine is not to be confused with dioscorin, the yam storage protein.) Origin and uses Dioscorine was first isolated from the tubers of ''Dioscorea hirsuta'' by Boorsma in 1894, and the tubers of ''Dioscor ...

Famine Food
A famine food or poverty food is any inexpensive or readily available food used to nourish people in times of hunger and starvation, whether caused by extreme poverty, such as during economic depression or war, or by natural disasters such as drought. Foods associated with famine need not be nutritionally deficient, or unsavory. People who eat famine food in large quantity over a long period of time may become averse to it over time. In times of relative affluence, these foods may become the targets of social stigma and rejection. The characterization of some foodstuffs as "famine" or "poverty" food can be social. For example lobster and other crustaceans may be considered poverty food in some societies and luxury food in others depending on time period and situation. Examples A number of foodstuffs have been strongly associated with famine, war, or times of hardship throughout history: *The breadnut or Maya nut was cultivated by the ancient Mayans but is largely reje ...

Dioscorea Transversa
''Dioscorea transversa'', the pencil yam, is a vine of eastern and northern Australia. The leaves are heart-shaped, shiny, with 5-7 prominent veins. The seed pods are rounded, green or pink before drying to a straw brown papery texture. The edible tubers are typically slender and long. There are two forms: an eastern rainforest and wet sclerophyll form which doesn't have bulbils, and a northern form which occurs in open forests and has small bulbils and large inground tubers. Uses The tubers were a staple food of Australian Aboriginals and are eaten after cooking, usually in ground ovens. The 1889 book 'The Useful Native Plants of Australia records that common names included "Long yam", Indigenous Australians from Central Queensland referred to it as "Kowar" and that "The small young tubers are eaten by the aborigines ic.without any preparation."

Dioscorea Pentaphylla
''Dioscorea pentaphylla'' is a species of flowering plant in the yam family known by the common name fiveleaf yam. It is native to southern and eastern Asia (China, India, Indochina, Indonesia, Philippines, etc.) as well as New Guinea and northern Australia. It is widely cultivated as a food crop and naturalized in Cuba and on several island chains in the Pacific (including Hawaii).Gucker, Corey L. 2009In: Fire Effects Information System, nline U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station, Fire Sciences Laboratory.Acevedo-Rodríguez, P. & Strong, M.T.

Dioscorea Nummularia
''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 Ancient Greece, 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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dioscorea Esculenta
''Dioscorea esculenta'', commonly known as the lesser yam, is a yam species native to Island Southeast Asia and introduced to Near Oceania and East Africa by early Austronesian voyagers. It is grown for their edible tubers, though it has smaller tubers than the more widely-cultivated ''Dioscorea alata'' and is usually spiny. Names In Vietnam, it is called ''khoai từ'' or ''củ từ''. It is used to make chè củ từ, also referred to as chè khoai từ. In Tagalog, it is known as ''tugi,'' while in Cebuano it is called ''apali''. It is cultivated in Kerala, Goa, Konkan parts of Maharashtra India. In Malayalam, it is known as ''nana kizhangu'' or ''nheruvalli kizhangu'' or Cheru Kizhangu". In Goa it is called ''Kaate Kanaga (काटे कणगा )'', It is a climber which needs support and goes coiling around the support. History of cultivation The lesser yam is the second most important yam crop among Austronesians. Like ''D. alata'', it requires minimal processing ...

Dioscorea Hispida
''Dioscorea hispida'', also known as the Indian three-leaved yam, (Tagalog: nami) is a species of yam in the genus ''Dioscorea'', native to South and Southeast Asia. Known to be poisonous when fresh, careful processing is required to render it edible. Culinary use Several peoples use the tuber as food. The tuber is toxic when fresh due to the presence of saponins and calcium oxalate raphides Raphides (pronounced /ˈræfɪˌdiz/, singular raphide /ˈreɪfʌɪd/ or raphis) are needle-shaped crystals of calcium oxalate monohydrate ( prismatic monoclinic crystals) or calcium carbonate as aragonite ( dipyramidal orthorhombic crystals), ..., so it must be processed prior to consumption, typically by finely slicing into thin strips, placing in a sack or net, and leaving in a stream for a few days until the toxins have leached out. It is then dehydrated and cooked. References hispida {{monocot-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dioscorea Bulbifera
''Dioscorea bulbifera'' (commonly known as the air potato, air yam, bitter yam, cheeky yam, potato yam, aerial yam, and parsnip yam) is a species of true yam in the yam family, Dioscoreaceae. It is native to Africa, Asia and northern Australia. It is widely cultivated and has become naturalized in many regions (Latin America, the West Indies, the Southeastern United States, and various oceanic islands). It is also known as the up-yam in Nigerian Pidgin English, since the plant is cultivated more for its bulbils than for its tubers. Description ''Dioscorea bulbifera'' is a perennial vine with broad, alternate leaves, and two types of storage organs. The plant forms bulbils in the leaf axils of the twining stems, and tubers beneath the ground. These tubers are like small, oblong potatoes. Some varieties are edible and cultivated as a food crop, especially in West Africa. The tubers of edible varieties often have a bitter taste, which can be removed by boiling. They can then ...
