Entandrophragma Utile
''Entandrophragma utile'', called the sipo or utile, is a species of large tree in the genus ''Entandrophragma'', native to nearly all of tropical Africa facing the Atlantic, from Guinea to Angola, and as far east as Uganda. The timber is traded as a tropical hardwood Hardwood is wood from dicot trees. These are usually found in broad-leaved temperate and tropical forests. In temperate and boreal latitudes they are mostly deciduous, but in tropics and subtropics mostly evergreen. Hardwood (which comes from .... It is sometimes called sipo mahogany.

Platycerium Elephantotis
''Platycerium'' is a genus of about 18 fern species in the polypod family, Polypodiaceae. Ferns in this genus are widely known as staghorn or elkhorn ferns due to their uniquely shaped fronds. This genus is epiphytic and is native to tropical and temperate areas of South America, Africa, Southeast Asia, Australia, and New Guinea. Description ''Platycerium'' sporophytes (adult plants) have tufted roots, growing from a short rhizome, and bear two types of fronds - basal and fertile fronds. Basal fronds are sterile, shield- or kidney-shaped, and laminate against the tree, to protect the fern's roots from damage and desiccation. In some ''Platycerium'' species, the top margin of these fronds will grow into an open crown of lobes; catching rainwater, falling forest litter, bird/animal droppings, and even the occasional fallen baby bird or deceased animal, these plants build up their own “compost” system of nutrition over many years. Fertile fronds bear spores on their undersurfac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Archibald Sprague
Thomas Archibald Sprague (7 October 1877, Edinburgh – 22 October 1958, Cheltenham, Gloucestershire, England) was a Scottish botanist. In 1938 he married botanist Mary Letitia Green, and together they authored several supplements to the ''Index Kewensis''. In 1954, botanist Balle (Simone Balle) published ''Spragueanella'', which is a genus of flowering plants from Tropical Africa belonging to the family Loranthaceae Loranthaceae, commonly known as the showy mistletoes, is a family of flowering plants. It consists of about 75 genera and 1,000 species of woody plants, many of them hemiparasites. The three terrestrial species are ''Nuytsia floribunda'' (the W ....

Entandrophragma
''Entandrophragma'' is a genus of eleven known species of deciduous trees in the family Meliaceae. Description ''Entandrophragma'' is restricted to tropical Africa.Entandrophragma C. DC. in Bull. Herb. Boissier 2:582 t.21 (1894) At least some of the species attain large sizes, reaching 40–50 m tall, exceptionally 60 m, and 2 m in trunk diameter.

Timber
Lumber is wood that has been processed into dimensional lumber, including beams and planks or boards, a stage in the process of wood production. Lumber is mainly used for construction framing, as well as finishing (floors, wall panels, window frames). Lumber has many uses beyond home building. Lumber is sometimes referred to as timber as an archaic term and still in England, while in most parts of the world (especially the United States and Canada) the term timber refers specifically to unprocessed wood fiber, such as cut logs or standing trees that have yet to be cut. Lumber may be supplied either rough- sawn, or surfaced on one or more of its faces. Beside pulpwood, ''rough lumber'' is the raw material for furniture-making, and manufacture of other items requiring cutting and shaping. It is available in many species, including hardwoods and softwoods, such as white pine and red pine, because of their low cost. ''Finished lumber'' is supplied in standard sizes, mostly ...

Hardwood
Hardwood is wood from dicot trees. These are usually found in broad-leaved temperate and tropical forests. In temperate and boreal latitudes they are mostly deciduous, but in tropics and subtropics mostly evergreen. Hardwood (which comes from angiosperm trees) contrasts with softwood (which is from gymnosperm trees). Characteristics Hardwoods are produced by angiosperm trees that reproduce by flowers, and have broad leaves. Many species are deciduous. Those of temperate regions lose their leaves every autumn as temperatures fall and are dormant in the winter, but those of tropical regions may shed their leaves in response to seasonal or sporadic periods of drought. Hardwood from deciduous species, such as oak, normally shows annual growth rings, but these may be absent in some tropical hardwoods. Hardwoods have a more complex structure than softwoods and are often much slower growing as a result. The dominant feature separating "hardwoods" from softwoods is the presence o ...

Sipo Oberfläche Radial
The ''Sicherheitspolizei'' ( en, Security Police), often abbreviated as SiPo, was a term used in Germany for security police. In the Nazi era, it referred to the state political and criminal investigation security agencies. It was made up by the combined forces of the Gestapo (secret state police) and the ''Kriminalpolizei'' (criminal police; Kripo) between 1936 and 1939. As a formal agency, the SiPo was incorporated into the Reich Security Main Office (RSHA) in 1939, but the term continued to be used informally until the end of World War II in Europe. Origins The term originated in August 1919 when the ''Reichswehr'' set up the ''Sicherheitswehr'' as a militarised police force to take action during times of riots or strikes. Owing to limitations in army numbers, it was renamed the ''Sicherheitspolizei'' to avoid attention. They wore a green uniform, and were sometimes called the "Green Police". It was a military body, recruiting largely from the ''Freikorps'', with NCOs and offi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trees Of Africa
In botany, a tree is a perennial plant with an elongated Plant stem, stem, or trunk (botany), trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller Arecaceae, palms, Cyatheales, tree ferns, Musa (genus), bananas, and bamboos are also trees. Trees are not a Taxon, taxonomic group but include a variety of plant species that Convergent evolution, have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has ...
