Dioscorea Cayennensis Subsp. Rotundata
''Dioscorea cayenensis'' subsp. ''rotundata'', commonly known as the white yam, West African yam, Guinea yam, or white ñame, is a subspecies of yam native to Africa. It is one of the most important cultivated yams. Kokoro is one of its most important cultivars. It is sometimes treated as separate species from '' Dioscorea cayenensis''. Domestication Its wild progenitor is '' Dioscorea praehensilis'' and possibly also '' D. abyssinica'' (by hybridization). Domestication occurred in West Africa, along the south-facing Atlantic coast. There is insufficient documentation and insufficient research to determine how long ago that occurred. Distribution ''D. c.'' subsp. ''rotundata'' is grown in West Africa, including countries such as Ivory Coast, Ghana and Nigeria. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flora Of West Tropical Africa
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) wa ...

Crops Originating From Africa
A crop is a plant that can be grown and harvested extensively for profit or subsistence. In other words, a crop is a plant or plant product that is grown for a specific purpose such as food, fibre, or fuel. When plants of the same species are cultivated in rows or other systematic arrangements, it is called crop field or crop cultivation. Most crops are harvested as food for humans or fodder for livestock. Important non-food crops include horticulture, floriculture, and industrial crops. Horticulture crops include plants used for other crops (e.g. fruit trees). Floriculture crops include bedding plants, houseplants, flowering garden and pot plants, cut cultivated greens, and cut flowers. Industrial crops are produced for clothing (fiber crops e.g. cotton), biofuel (energy crops, algae fuel), or medicine (medicinal plants). Production There was an increase in global production of primary crops by 56% between 2000 and 2022 to 9.6 billion tonnes, which represents a 0.7% com ...

Most Recent Common Ancestor
A most recent common ancestor (MRCA), also known as a last common ancestor (LCA), is the most recent individual from which all organisms of a set are inferred to have descended. The most recent common ancestor of a higher taxon is generally assumed to have been a species. The term is also used in reference to the ancestry of groups of genes (haplotypes) rather than organisms. The ancestry of a set of individuals can sometimes be determined by referring to an established pedigree, although this may refer only to patrilineal or matrilineal lines for sexually-reproducing organisms with two parents, four grandparents, etc. However, in general, it is impossible to identify the exact MRCA of a large set of individuals, but an estimate of the time at which the MRCA lived can often be given. Such ''time to most recent common ancestor'' (''TMRCA'') estimates can be given based on DNA test results and established mutation rates as practiced in genetic genealogy, or by reference to a non- ...

Yam (vegetable)
Yam is the common name for some plant species in the genus ''Dioscorea'' (family Dioscoreaceae) that form edible tubers (some other species in the genus being toxic). Yams are perennial herbaceous vines native to Africa, Asia, and the Americas and cultivated for the consumption of their starchy tubers in many temperate climate, temperate and tropics, tropical regions. The tubers themselves, also called "yams", come in a variety of forms owing to numerous cultivars and related species. Description A Monocotyledon, monocot related to lilies and grasses, yams are vigorous herbaceous, perennial plant, perennially growing vines from a tuber. Some 870 species of yams are known, a few of which are widely grown for their edible tuber but others of which are toxic (such as ''Dioscorea communis, D. communis''). Yam plants can grow up to in length and high. The tuber may grow into the soil up to deep. The plant disperses by seed. The edible tuber has a rough skin that is diffi ...
