Meliaceae Genera
Meliaceae, the mahogany family, is a flowering plant family of mostly trees and shrubs (and a few herbaceous plants, mangroves) in the order Sapindales. They are characterised by alternate, usually pinnate leaves without stipules, and by syncarpous, apparently bisexual (but actually mostly cryptically unisexual) flowers borne in panicles, cymes, spikes, or clusters. Most species are evergreen, but some are deciduous, either in the dry season or in winter. The family includes about 53 genera and about 600 known species, with a pantropical distribution; one genus ('' Toona'') extends north into temperate China and south into southeast Australia, another (''Synoum'') into southeast Australia, and another (''Melia'') nearly as far north. They most commonly grow as understory trees in rainforests, but are also found in mangroves and arid regions. The fossil record of the family extends back into the Late Cretaceous.

Melia Azedarach
''Melia azedarach'', commonly known as the chinaberry tree, pride of India, bead-tree, Cape lilac, syringa berrytree, Persian lilac, Indian lilac, or white cedar, is a species of deciduous tree in the mahogany family, Meliaceae, that is native to Indomalaya and Australasia. Description The fully grown tree has a rounded crown, and commonly measures tall, exceptionally . The leaves are up to long, alternate, long-petioled, two or three times compound (odd-pinnate); the leaflets are dark green above and lighter green below, with serrate margins. The flowers are small and fragrant, with five pale purple or lilac petals, growing in clusters. The fruit is a drupe, marble-sized, light yellow at maturity, hanging on the tree all winter, and gradually becoming wrinkled and almost white. As the stem ages and grows, changes occur that transform its surface into bark. Chemistry Italo et al 2009 and Safithri and Sari 2016 report flavonoids and phenols found in ''M. azed ...

Toona
''Toona'', commonly known as redcedar, toon (also spelled tun) or toona, tooni (in India) is a genus in the mahogany family, Meliaceae, native from Afghanistan south to India, and east to North Korea, Papua New Guinea and eastern Australia. In older texts, the genus was often incorporated within a wider circumscription of the related genus '' Cedrela'', but that genus is now restricted to species from the Americas. Uses Ornamental use '' Toona sinensis'' is of interest as by far the most cold-tolerant species in the Meliaceae, native in China as far north as 40°N in the Beijing area, where its tender shoots, called ''xiangchun'' (), are a traditional local leaf vegetable. It is the only member of the family that can be cultivated successfully in northern Europe, where it is sometimes planted as an ornamental tree in parks and avenues. Until recently, it had no widespread English common name, though Chinese Mahogany (reflecting its botanical relationship) is now used (e.g. Rush ...

Guarea
''Guarea'' is a genus of evergreen trees or shrubs in the family Meliaceae, native to tropical Africa and Central and South America. At their largest, they are large trees 20–45 m tall, with a trunk over 1 m diameter, often buttressed at the base. The leaves are pinnate, with 4–6 pairs of leaflets, the terminal leaflet present. They are dioecious, with male and female flowers on separate plants. The flowers are produced in loose inflorescences, each flower small, with 4–5 yellowish petals. The fruit is a four or five-valved capsule, containing several seeds, each surrounded by a yellow-orange fleshy aril; the seeds are dispersed by hornbills and monkeys which eat the aril. Species Species accepted by Plants of the World Online as of March 2019: Uses The timber is important; the African species are known as bossé, guarea, or pink mahogany, and the South American species as cramantee or American muskwood. It is said to possibly cause hallucinations if ingested. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Entandrophragma Cylindricum
''Entandrophragma cylindricum'' is a tree of the genus '' Entandrophragma'' of the family ''Meliaceae''. It is commonly known as sapele or sapelli ( ) or sapele mahogany, as well as aboudikro, assi, and muyovu. Origin of the name The name ''sapele'' comes from that of the city of Sapele in Nigeria, where there is a preponderance of the tree. African Timber and Plywood (AT&P), a division of the United Africa Company, had a factory at this location where the wood, along with ''Triplochiton scleroxylon'', ''Obeche'', mahogany, and Khaya was processed into timber which was then exported from the Port of Sapele worldwide. The name of the city itself is said to be an anglicisation of the Urhobo word Uriapele, commemorating a local deity. It is believed the British colonial authorities changed the name of the then hamlet to Sapele as it was easier to pronounce. Description ''Entandrophragma cylindricum'' is native to tropical Africa.

Cedrela Odorata
''Cedrela odorata'' is a commercially important species of tree in the chinaberry family, Meliaceae, commonly known as Spanish cedar or Cuban cedar; it is also known as cedro in Spanish. Classification The genus ''Cedrela'' has undergone two major systematic revisions since 1960. The most recent revision reduced the number of species in the genus to seven (Styles, 1981). The common cedro, ''Cedrela odorata'' L., embraces 28 other synonyms, including ''C. mexicana'' M. J. Roem. The taxon "''C. angustifolia''," a very vigorous type now in demand because of its apparent resistance to the shootborer, was left in an indeterminate status due to insufficient herbarium material. The result is that ''C. odorata'' as now constituted is a species showing a high degree of population variation. Distribution and habitat Cedro is a tree of the New World tropics, appearing in forests of moist and seasonally dry subtropical or tropical life zones (24) from latitude 26°N on the ...

Neem Tree
''Azadirachta indica'', commonly known as neem, nimtree or Indian lilac, is a tree in the mahogany family Meliaceae. It is one of two species in the genus ''Azadirachta'', and is native to the Indian subcontinent and most of the countries in Africa. It is typically grown in tropical and semi-tropical regions. Neem trees also grow on islands in southern Iran. Its fruits and seeds are the source of neem oil. Description Neem is a fast-growing tree that can reach a height of , and rarely . It is deciduous, shedding many of its leaves during the dry winter months. The branches are wide and spreading. The fairly dense crown is roundish and may reach a diameter of . The neem tree is similar in appearance to its relative, the chinaberry ('' Melia azedarach''). The opposite, pinnate leaves are long, with 20 to 30 medium to dark green leaflets about long. The terminal leaflet often is missing. The petioles are short. White and fragrant flowers are arranged in more-or-less drooping a ...

Wood
Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or woodchips or fiber. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the ...

Insecticide
Insecticides are substances used to kill insects. They include ovicides and larvicides used against insect eggs and larvae, respectively. Insecticides are used in agriculture, medicine, industry and by consumers. Insecticides are claimed to be a major factor behind the increase in the 20th-century's agricultural productivity. Nearly all insecticides have the potential to significantly alter ecosystems; many are toxic to humans and/or animals; some become concentrated as they spread along the food chain. Insecticides can be classified into two major groups: systemic insecticides, which have residual or long term activity; and contact insecticides, which have no residual activity. The mode of action describes how the pesticide kills or inactivates a pest. It provides another way of classifying insecticides. Mode of action can be important in understanding whether an insecticide will be toxic to unrelated species, such as fish, birds and mammals. Insecticides may be repellen ...
