Octolobus Grandis
''Octolobus'' is a genus of tropical forest trees in the family Malvaceae, subfamily Sterculioideae (previously placed in the Sterculiaceae). They are found in Central and West Africa and are closely related to the genus ''Cola''. Both share a leaf structure with entire margins, featuring a cuneate base, three main veins, a pulvinus at the petiole tip, weak brochidodromous secondary veins, and multicellular glandular hairs on the epidermis.

Tropical Forest
Tropical forests are forested ecoregions with tropical climates – that is, land areas approximately bounded by the Tropic of Cancer, tropics of Cancer and Tropic of Capricorn, Capricorn, but possibly affected by other factors such as prevailing winds. Some tropical forest types are difficult to categorize. While forests in temperate climate, temperate areas are readily categorized on the basis of tree canopy density, such schemes do not work well in tropical forests. There is no single scheme that defines what a forest is, in tropical regions or elsewhere.Anatoly Shvidenko, Charles Victor Barber, Reidar Persson et al. 2005 "Millennium Ecosystem Assessment." Ecosystems and human wellbeing: a framework for assessment Washington, DC: Island Press Because of these difficulties, information on the extent of tropical forests varies between sources. However, tropical forests are extensive, making up just under half the world's forests. The tropical domain has the largest proportion of ...

Malvaceae
Malvaceae (), or the mallows, is a family of flowering plants estimated to contain 244 genera with 4225 known species. Well-known members of economic importance include Theobroma cacao, cacao, Cola (plant), cola, cotton, okra, Hibiscus sabdariffa, roselle and durian. There are also some genera containing familiar ornamentals, such as ''Alcea'' (hollyhock), ''Malva'' (mallow), and ''Tilia'' (lime or linden tree). The genera with the largest numbers of species include ''Hibiscus'' (434 species), ''Pavonia (plant), Pavonia'' (291 species), ''Sida (plant), Sida'' (275 species), ''Ayenia'' (216 species), ''Dombeya'' (197 species), and ''Sterculia'' (181 species). Taxonomy and nomenclature The circumscription of the Malvaceae is controversial. The traditional Malvaceae ''sensu stricto'' comprise a very homogeneous and cladistically Monophyly, monophyletic group. Another major circumscription, Malvaceae ''sensu lato'', has been more recently defined on the basis that genetics studies ha ...

Sterculioideae
Sterculioideae is a subfamily of the family (biology), family Malvaceae containing evergreen and deciduous tree and shrub genera, that were previously placed in the obsolete family Sterculiaceae. Taxonomy A 2006 molecular study indicated the Sterculioideae was most likely to be a monophyletic group, and that it had four major clades within it. However, the relationships between the clades were not resolved. The clades consist of: * a ''Cola'' clade, with the genera ''Cola (plant), Cola'' and ''Octolobus'' of Africa and ''Pterygota (plant), Pterygota'' of Africa, South America and southeast Asia forming a subclade, ''Hildegardia (plant), Hildegardia'' and ''Firmiana'' forming a second and ''Scaphium'' and ''Pterocymbium'' a third. * ''Heritiera'' clade comprising the genus ''Heritiera'' * ''Sterculia'' clade comprising the large genus ''Sterculia'' of Australasia and Asia. * ''Brachychiton'' clade of Australasian and New Caledonian species, including ''Brachychiton'', ''Acropogon' ...

Cola (plant)
''Cola'' is a genus of trees native to the tropical forests of Africa, classified in the family Malvaceae, subfamily Sterculioideae (previously in the separate family Sterculiaceae). Species in this genus are sometimes referred to as kola tree or kola nut for the caffeine-containing fruit produced by the trees that is often used as a flavoring ingredient in beverages. The genus was thought to be closely related to the South American genus '' Theobroma'', or cocoa, but the latter is now placed in a different subfamily. They are evergreen trees, growing up to 20 m tall (about 60 feet), with glossy ovoid leaves up to 30 cm long and star-shaped fruit. Origin and distribution ''Cola'' is a genus of the Family Malvaceae with approximately 100 to 125 species occurring in the evergreen lowland and montane forest of continental (primarily tropical) Africa. The earliest known evidence of ''Cola'' is ''Cola amharaensis'', a well-preserved fossil leaf compression from the late Oligocene ...

Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...

Trees Of Africa
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that 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 trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are around three trillion mature trees in the world currently. A tree typically has many secondary branches supported clear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
