Baphia Nitida
''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. Pterocarpin is a pterocarpan Pterocarpans are derivatives of isoflavonoids found in the family Fabaceae.

Osyris Lanceolata
''Osyris lanceolata'', also known as African sandalwood or Camwood, is used for its scented wood and to extract essential oil. The hemi-parasitic plant is found from South Africa to Zimbabwe and east Africa, including Tanzania, Kenya and Uganda; northwest Africa; the southern half of the Iberian Peninsula and Macaronesia. 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 Overexploitation, also called overharvesting, refers to harvesting a renewable resource to the point of diminishing returns. Continued overexploitation can lead to the destruction of the resource, as it will be unable to replenish. The term ap ... in parts of its range despite legal protection.

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 for use. 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 चन्दनं ''Chandana'' (''čandana''), meaning "wood for burning incense" and related to ''candrah'', "shining, glowing" and the Latin ''candere'', to shine or glow. It arrived in English via Late Greek, Medieval Latin and Old French in the 14th or 15th century. The sandalwood is indige ...

Leguminous
A legume () is a plant in the family Fabaceae (or Leguminosae), or the fruit or seed of such a plant. When used as a dry grain, the seed is also called a pulse. Legumes are grown agriculturally, primarily for human consumption, for livestock forage and silage, and as soil-enhancing green manure. Well-known legumes include beans, soybeans, chickpeas, peanuts, lentils, lupins, mesquite, carob, tamarind, alfalfa, and clover. 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. Legumes are notable in that most of them have symbiotic nitrogen-fixing bacteria in structures called root nodules. For that reason, they 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 consid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 upwards to fill the gap. These trees tend to have straight trunks ...

Evergreen
In botany, an evergreen is a plant which has foliage that remains green and functional through more than one growing season. This also pertains to plants that retain their foliage only in warm climates, and contrasts with deciduous plants, which completely lose their foliage during the winter or dry season. Evergreen species There are many different kinds of evergreen plants, both trees and shrubs. Evergreens include: *Most species of conifers (e.g., pine, hemlock, blue spruce, and red cedar), but not all (e.g., larch) *Live oak, holly, and "ancient" gymnosperms such as cycads *Most angiosperms from frost-free climates, and rainforest trees *All Eucalypts * Clubmosses and relatives *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'' (a sequoia) Leaf longevity in evergreen plants varies from a few months ...

Yoruba Language
Yoruba (, ; Yor. '; Ajami script, Ajami: ) is a language spoken in West Africa, primarily in South West (Nigeria), Southwestern Middle Belt, and Central Nigeria. It is spoken by the Ethnic group, ethnic Yoruba people. The number of Yoruba speakers is roughly 50 million, plus about 2 million second-language speakers. As a pluricentric language, it is primarily spoken in a dialectal area spanning Nigeria and Benin with smaller migrated communities in Côte d'Ivoire, Sierra Leone and The Gambia. Yoruba vocabulary is also used in the Afro-Brazilian religion known as Candomblé, in the Caribbean religion of Santería in the form of the liturgical Lucumí language and various Afro-American religions of North America. Practitioners of these religions in the Americas no longer speak or understand the Yorùbá language, rather they use remnants of Yorùbá language for singing songs that for them are shrouded in mystery. Usage of a lexicon of Yorùbá words and short phrases during ritua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 simple 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 misterie' 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 A newel, also called a central pole or support column, is the cent ...

Alkali
In chemistry, an alkali (; from ar, القلوي, al-qaly, lit=ashes of the saltwort) is a basic, ionic 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 ''the calcined ashes'' (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 ...

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 reassigned ''Baphia'' to the tribe Baphieae. Species ''Baphia'' comprises the following species: Section ''Alata'' M.O.Soladoye * ''Baphia cordifolia'' Harms Section ''Baphia'' Lodd.
