Epipetrum
''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] |

Dioscoreaceae
Dioscoreaceae () is a family of monocotyledonous flowering plants, with about 715 known species in nine genera. The best-known member of the family is the yam (some species of '' Dioscorea''). The APG system (1998) and APG II system (2003) both place it in the order Dioscoreales, in the clade monocots. However, the circumscription changed in the APG II system, with the 2003 system expanded to include the plants that in the 1998 system were treated in the families Taccaceae and Trichopodaceae. Taxonomy The Dioscoreaceae were first described by Brown in 1810 as Dioscoreae, and alternatively referred to as Dioscorinae. Subdivision The circumscription of Dioscoreaceae has expanded over the years. For instance when Stenomeridaceae, as '' Stenomeris'' was also included in Dioscoreaceae as subfamily Stenomeridoideae together with ''Avetra'', the remaining four genera were grouped in subfamily Dioscoreoideae, the two being distinguished by the presence of bisexual and unisexual flowers ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in 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 continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mangyan
Mangyan is the generic name for the eight indigenous groups found on the island of Mindoro, southwest of the island of Luzon, the Philippines, each with its own tribal name, language, and customs. The total population may be around 280,001, but official statistics are difficult to determine under the conditions of remote areas, reclusive tribal groups and some having little if any outside world contact. The ethnic groups of the island, from north to south, are: Iraya, Alangan, Tadyawan, Tawbuid (called Batangan by lowlanders on the west of the island), Buhid, and Hanunoo. An additional group on the south coast is labelled Ratagnon. They appear to be intermarried with lowlanders. The group known on the east of Mindoro as Bangon may be a subgroup of Tawbuid, as they speak the 'western' dialect of that language. They also have a kind of poetry which is called the Ambahan. Origins The Mangyans were once the only inhabitants of Mindoro. Being coastal dwellers at first, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Dioscorea alatipes'' is a herbaceous vine in the genus '' Dioscorea''. It is indigenous to the Morondava Prefecture in Madagascar and is listed as an vulnerable on the IUCN Red List in 2017, having previously been listed as endangered in 2001. It has been confused with another ''Dioscorea'' species, ''D. bako'' which is a food source of the indigenous people of the region.

Dioscorea Alata
''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.
