Distemonanthus
''Distemonanthus'' is a genus of flowering plants in the family Fabaceae. It belongs to the subfamily Dialioideae. It contains a single species, ''Distemonanthus benthamianus'', a deciduous tree, which occurs widely but sparsely in the forest regions of Tropical West and Central Africa; it is sometimes confused with ''Pericopsis laxiflora'' due to similar morphological features. Mature heartwood has a moderate resistance to fungi. Description A big tree, it grows up to 40 meters tall and 90 cm in diameter. Trunk is straight but can sometimes be slightly sinuous; fairly spreading buttress roots Buttress roots also known as plank roots are large, wide roots on all sides of a shallowly rooted tree. Typically, they are found in nutrient-poor tropical forest soils that may not be very deep. They prevent the tree from falling over (hence t ... at the base, free of branches for up to 20 meters.

Dialioideae
The subfamily Dialioideae is one of the subdivisions of the plant family Fabaceae (legumes). This subfamily includes many tropical trees and shrubs. The subfamily consists of 17 genera, which are widespread throughout the tropics. It has the following clade-based definition: The most inclusive crown clade containing '' Poeppigia procera'' C.Presland ''Dialium guianense'' (Aubl.) Sandwith, but not ''Cercis canadensis'' L., '' Duparquetia orchidacea'' Baill., or '' Bobgunnia fistuloides'' (Harms) J. H. Kirkbr. & Wiersema Members of the family also share the following morphological characteristics: the presence of cymose inflorescences, the absence of vestured pits in the xylem, and a high degree of organ loss.

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fabaceae
The Fabaceae or Leguminosae,International Code of Nomenclature for algae, fungi, and plants. Article 18.5 states: "The following names, of long usage, are treated as validly published: ....Leguminosae (nom. alt.: Fabaceae; type: Faba Mill. Vicia L.; ... When the Papilionaceae are regarded as a family distinct from the remainder of the Leguminosae, the name Papilionaceae is conserved against Leguminosae."

Taxon (journal)
''Taxon'' is a bimonthly peer-reviewed scientific journal covering plant taxonomy. It is published by Wiley on behalf of the International Association for Plant Taxonomy, of which it is the official journal. It was established in 1952 and is the only place where nomenclature proposals and motions to amend the International Code of Nomenclature for algae, fungi, and plants (except for the rules concerning fungi) can be published. The editor-in-chief is Dirk C. Albach (University of Oldenburg). Abstracting and indexing The journal is abstracted and indexed in: According to the ''Journal Citation Reports'', the journal has a 2020 impact factor The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index calculated by Clarivate that reflects the yearly mean number of citations of articles published in the last two years in a given journal, as i ... of 2.817.

Pericopsis Laxiflora
''Pericopsis laxiflora'' is a woody deciduous shrub or tree within the Fabaceae family. Sold commercially as satin wood, it is known in some regions as Kulu Kulu, among the Hausa speaking people, it is called Makarfo, the Yorubas call it Ayan and the Igbos call it Abua-Ocha. It is one of three species in the genus Pericopsis genus that occurs in Africa. The species contains the alkaloids: N-methylcytisine, ammodendrine, and choline. Description A tree or shrub, common growth reaches between 9 and 12 meters tall but occasionally grows up to 2 meters tall as a shrub. Trunk usually twisted, rarely straight and with twisted branches, bark is smooth, grey to beige in color while stem is pubescent. Leaves, alternate arrangement, 4 - 6 pairs, upper surface imparipinate, shiny and lower surface glabrous. Leaf-blade, lanceolate to ovate in outline, 3 – 7 cm long and 2.5 – 5 cm wide, acuminate apex with cuneate base. Petiole, 15 – 20 cm long. Distribution Occu ...

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 productio ...

Buttress Root
Buttress roots also known as plank roots are large, wide roots on all sides of a shallowly rooted tree. Typically, they are found in nutrient-poor tropical forest soils that may not be very deep. They prevent the tree from falling over (hence the name buttress) while also gathering more nutrients. Buttresses are tension elements, being larger on the side away from the stress of asymmetrical canopies. The roots may intertwine with buttress roots from other trees and create an intricate mesh, which may help support trees surrounding it. They can grow up to tall and spread for 30 metres above the soil then for another 30 metres below. When the roots spread horizontally, they are able to cover a wider area for collecting nutrients. They stay near the upper soil layer because all the main nutrients are found there. Buttress roots vary greatly in size from barely discernable to many square yards (square meters) of surface. The largest for which there is photographic evidence is a More ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upper Guinean Forests
The Upper Guinean forests is a tropical seasonal forest region of West Africa. The Upper Guinean forests extend from Guinea and Sierra Leone in the west through Liberia, Côte d'Ivoire and Ghana to Togo in the east, and a few hundred kilometers inland from the Atlantic coast. A few enclaves of montane forest lie further inland in the mountains of central Guinea and central Togo and Benin. In the drier interior, the Upper Guinean forests yield to the Guinean forest-savanna mosaic, a belt of dry forests and savannas that lies between the coastal forests and the savannas and grasslands of the Sudan further north. The Dahomey Gap, a region of Togo and Benin where the Guinean forest-savanna mosaic extends to the Atlantic coast, separates the Upper Guinean forests from the Lower Guinean forests to the east, which extend from eastern Benin through Nigeria, Cameroon, and south along the coast of the Gulf of Guinea. The Upper Guinean forests are a Global 200 ecoregion. The Guinean moist fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lower Guinean Forests
The Lower Guinean forests is region of coastal tropical moist broadleaf forest in West Africa, extending along the eastern coast of the Gulf of Guinea from eastern Benin through Nigeria and Cameroon. The Dahomey Gap, a region of savanna and dry forest in Togo and Benin, divides the Lower Guinean forests from the Upper Guinean forests to the west, which extend along the western coast of the Gulf of Guinea from Togo to Liberia and north to Guinea. To the north and northeast, the Lower Guinean forests transition to the drier inland Guinean forest–savanna mosaic and Northern Congolian forest–savanna mosaic and to the southeast by the Congolian Coastal forests, whose boundary is the Sanaga River in Cameroon.Linder, H.
