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 ...

Tree
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 cle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Herbarium
A herbarium (plural: herbaria) is a collection of preserved plant biological specimen, specimens and associated data used for scientific study. The specimens may be whole plants or plant parts; these will usually be in dried form mounted on a sheet of paper (called ''exsiccatum'', plur. ''exsiccata'') but, depending upon the material, may also be stored in boxes or kept in alcohol or other preservative. The specimens in a herbarium are often used as reference material in describing plant taxon, taxa. Some specimens may be Type (botany), types, some may be specimens distributed in published series called exsiccata, exsiccatae. The term herbarium is often used in mycology to describe an equivalent collection of preserved fungi, otherwise known as a fungarium. A xylarium is a herbarium specialising in specimens of wood. The term hortorium (as in the Liberty Hyde Bailey, Liberty Hyde Bailey Hortorium) has occasionally been applied to a herbarium specialising in preserving material of ...

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 and south along the coast of the Gulf of Guinea. The Upper Guinean forests are a Global 200 ecoregion. The Guinean moist forests a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ayenia
''Ayenia'' is a genus of flowering plants in the mallow family, Malvaceae. It includes 216 species of subshrubs, shrubs, small trees, and lianas.Whitlock, B. A., & Hale, A. M. (2011)The phylogeny of ''Ayenia'', ''Byttneria'', and ''Rayleya'' (Malvaceae ''s.l.'') and its implications for the evolution of growth forms.''Systematic Botany'', 36(1), 129-136. They are native to the tropical Americas and southwestern United States, tropical Africa, and tropical Asia. Description ''Ayenia'' includes subshrubs, shrubs, small trees, and lianas. The genus is distinguished by its tiny yet extraordinarily complex flowers. Ecology Species of ''Ayenia'' grow in diverse habitats, from open areas in dry and seasonally-dry regions to humid forests, river banks, and from lowlands to high elevations. ''Byttneria'' species are host plants to insects such as beetles of the genus '' Lonchophorellus''. Taxonomy ''Ayenia'', ''Byttneria'', and ''Rayleya'' were formerly described as separate genera, wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of Ivory Coast
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becoming ...

Extinct Plants
Extinction is the termination of an organism by the death of its last member. A taxon may become functionally extinct before the death of its last member if it loses the capacity to reproduce and recover. As a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, and mammoths. Through evolution, species arise through the process of speciation. Species become extinct when they are no longer able to survive in changing conditions or against superio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
