Camwood
''Baphia nitida'', also known as camwood, barwood, and African sandalwood (although not a true sandalwood), is a shrubby, leguminous, hard-wooded tree from central west Africa. It is a small understorey, evergreen tree, often planted in villages, and known as ''osun'' in Yoruba. The wood is of a very fine colour, and is used in woodturning for making knife handles and similar articles. The tree's bark and heartwood are commonly used to make a brilliant but non-permanent red dye, which is soluble in alkali In chemistry, an alkali (; from the Arabic word , ) is a basic salt of an alkali metal or an alkaline earth metal. An alkali can also be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0. The a .... Pterocarpin is a pterocarpan found in ''B. nitida''. Osun (camwood) extract is also used in some soaps and skin treatments, primarily among the Yoruba people of West Africa. The extract of the Camwood can be formed into ...

Osyris Lanceolata
''Osyris lanceolata'', also known as African sandalwood, watta bush or Camwood, is used for its scented wood and to extract essential oil. The semi-parasitic plant is found from South Africa to Zimbabwe and east Africa, including Tanzania, Kenya and Uganda; northwest Africa; the Canary Islands and the southern half of the Iberian Peninsula. It grows in rocky areas or along the margins of dry forest, but is usually not abundant in any one place. The wood is overexploited in parts of its range despite legal protection. In Somaliland Somaliland, officially the Republic of Somaliland, is an List of states with limited recognition, unrecognised country in the Horn of Africa.

Baphia
''Baphia'' is a small genus of legumes that bear simple leaves. ''Baphia'' is from the Greek word βάπτω (''báptō-'', "to dip" or "to dye"), referring to a red dye that is extracted from the heartwood of tropical species. The genus is restricted to the African tropics. ''Baphia'' was traditionally assigned to the tribe Sophoreae; however, recent molecular phylogenetic analyses Circumscription (taxonomy), reassigned ''Baphia'' to the tribe Baphieae.

Sandalwood
Sandalwood is a class of woods from trees in the genus ''Santalum''. The woods are heavy, yellow, and fine-grained, and, unlike many other aromatic woods, they retain their fragrance for decades. Sandalwood oil is extracted from the woods. Sandalwood is often cited as one of the most expensive woods in the world. Both the wood and the oil produce a distinctive fragrance that has been highly valued for centuries. Consequently, some species of these slow-growing trees have suffered over-harvesting in the past. Nomenclature The nomenclature and the taxonomy of the genus are derived from this species' historical and widespread use. Etymologically it is ultimately derived from Sanskrit ''Chandana'' (''čandana''), meaning "wood for burning incense" and related to ''candrah'', "shining, glowing" and the Latin , to shine or glow. It arrived in English via Late Greek, Medieval Latin and Old French in the 14th or 15th century. True sandalwoods Sandalwoods are medium-sized Parasitic pl ...

Leguminous
Legumes are plants in the pea family Fabaceae (or Leguminosae), or the fruit or seeds of such plants. When used as a dry grain for human consumption, the seeds are also called pulses. Legumes are grown agriculturally, primarily for human consumption, but also as livestock forage and silage, and as soil-enhancing green manure. Legumes produce a botanically unique type of fruit – a simple dry fruit that develops from a simple carpel and usually dehisces (opens along a seam) on two sides. Most legumes have symbiotic nitrogen-fixing bacteria, Rhizobia, in structures called root nodules. Some of the fixed nitrogen becomes available to later crops, so legumes play a key role in crop rotation. Terminology The term ''pulse'', as used by the United Nations' Food and Agriculture Organization (FAO), is reserved for legume crops harvested solely for the dry seed. This excludes green beans and green peas, which are considered vegetable crops. Also excluded are seeds that are mainl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Africa
Africa is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth's land area and 6% of its total surface area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With nearly billion people as of , it accounts for about of the world's human population. Demographics of Africa, Africa's population is the youngest among all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Based on 2024 projections, Africa's population will exceed 3.8 billion people by 2100. Africa is the least wealthy inhabited continent per capita and second-least wealthy by total wealth, ahead of Oceania. Scholars have attributed this to different factors including Geography of Africa, geography, Climate of Africa, climate, corruption, Scramble for Africa, colonialism, the Cold War, and neocolonialism.

Understorey
In forestry and ecology, understory (American English), or understorey (Commonwealth English), also known as underbrush or undergrowth, includes plant life growing beneath the forest canopy without penetrating it to any great extent, but above the forest floor. Only a small percentage of light penetrates the canopy, so understory vegetation is generally shade-tolerant. The understory typically consists of trees stunted through lack of light, other small trees with low light requirements, saplings, shrubs, vines, and undergrowth. Small trees such as holly and dogwood are understory specialists. In temperate deciduous forests, many understory plants start into growth earlier in the year than the canopy trees, to make use of the greater availability of light at that particular time of year. A gap in the canopy caused by the death of a tree stimulates the potential emergent trees into competitive growth as they grow upward to fill the gap. These trees tend to have straight trunks ...

Evergreen
In botany, an evergreen is a plant which has Leaf, foliage that remains green and functional throughout the year. This contrasts with deciduous plants, which lose their foliage completely during the winter or dry season. Consisting of many different species, the unique feature of evergreen plants lends itself to various environments and purposes. Evergreen species There are many different kinds of evergreen plants, including trees, shrubs, and vines. Evergreens include: * Most species of conifers (e.g., pine, Tsuga, hemlock, spruce, and fir), but not all (e.g., larch). * Live oak, holly, and "ancient" gymnosperms such as cycads * Many woody plants from frost-free climates * Rainforest trees * All eucalypts * Lycopodiopsida, Clubmosses and relatives * Most bamboos The Latin binomial term , meaning "always green", refers to the evergreen nature of the plant, for instance: :''Cupressus sempervirens'' (a cypress) :''Lonicera sempervirens'' (a honeysuckle) :''Sequoia sempervirens'' ...

Yoruba Language
Yoruba (, ; Yor. ) is a Niger–Congo languages, Niger-Congo language that is spoken in West Africa, primarily in South West (Nigeria), Southwestern and Middle Belt, Central Nigeria, Benin, and parts of Togo. It is spoken by the Yoruba people. Yoruba speakers number roughly 50 million, including around 2 million second-language or L2 speakers. As a pluricentric language, it is primarily spoken in a dialectal area spanning Nigeria, Benin, and Togo with smaller migrated communities in Côte d'Ivoire, Sierra Leone and The Gambia. Yoruba vocabulary is also used in African diaspora religions such as the Afro-Brazilian religion of Candomblé, the Caribbean religion of Santería in the form of the liturgical Lucumí language, and various Afro-American religions of North America. Most modern practitioners of these religions in the Americas are not fluent in the Yoruba language, yet they still use Yoruba words and phrases for songs or chants—rooted in cultural traditions.

Woodturning
Woodturning is the craft of using a wood lathe with hand-held tools to cut a shape that is symmetrical around the axis of rotation. Like the potter's wheel, the wood lathe is a mechanism that can generate a variety of forms. The operator is known as a ''turner'', and the skills needed to use the tools were traditionally known as ''turnery''. In pre-industrial England, these skills were sufficiently difficult to be known as "the mysteries of the turners' guild." The skills to use the tools by hand, without a fixed point of contact with the wood, distinguish woodturning and the wood lathe from the machinist's lathe, or metal-working lathe. Items made on the lathe include tool handles, candlesticks, egg cups, knobs, lamps, rolling pins, cylindrical boxes, Christmas ornaments, bodkins, knitting needles, needle cases, thimbles, pens, chessmen, spinning tops; legs, spindles, and pegs for furniture; balusters and newel posts for architecture; baseball bats, hollow forms such a ...

Alkali
In chemistry, an alkali (; from the Arabic word , ) is a basic salt of an alkali metal or an alkaline earth metal. An alkali can also be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0. The adjective alkaline, and less often, alkalescent, is commonly used in English as a synonym for basic, especially for bases soluble in water. This broad use of the term is likely to have come about because alkalis were the first bases known to obey the Arrhenius definition of a base, and they are still among the most common bases. Etymology The word ''alkali'' is derived from Arabic ''al qalīy'' (or ''alkali''), meaning (see calcination), referring to the original source of alkaline substances. A water-extract of burned plant ashes, called potash and composed mostly of potassium carbonate, was mildly basic. After heating this substance with calcium hydroxide (''slaked lime''), a far more strongly basic substance known as ''caustic potash ...

Pterocarpan
Pterocarpans are derivatives of isoflavonoids found in the family Fabaceae. It is a group of compounds which can be described as benzo-pyrano-furano-benzenes (i.e. 6''H''-[1]benzofuro[3,2-c]chromene skeleton) which can be formed by coupling of the B ring to the 4-one position. 2'-hydroxyisoflavone reductase is the enzyme responsible for the conversion in ''Cicer arietinum'' and glyceollin synthase for the production of glyceollins, phytoalexins in soybean.
