Gyranthera Caribensis
''Gyranthera caribensis'' is a large tree in the tropical rainforests of northern Venezuela, where it is endemic in the Venezuelan Coastal Range. Traditionally placed in the baobab family, which is now a subfamily Bombacoideae of the family Malvaceae. One notable individual called "El Piè Grande" ("Bigfoot"), near Orqueta in Yaracuy State in northern Venezuela, has a height of 63.43 m and a girth of 17.12 m. The tree was described by the botanist Henri François Pittier Henri François Pittier de Fabrega (August 13, 1857 in Bex, Switzerland – January 27, 1950 in Caracas, Venezuela) was a Swiss-born geographer and botanist who started Venezuelan National Park history.

Tropical Rainforest
Tropical rainforests are dense and warm rainforests with high rainfall typically found between 10° north and south of the Equator. They are a subset of the tropical forest biome that occurs roughly within the 28° latitudes (in the torrid zone between the Tropic of Cancer and Tropic of Capricorn). Tropical rainforests are a type of tropical moist broadleaf forest, that includes the more extensive seasonal tropical forests. True rainforests usually occur in tropical rainforest climates where no dry season occurs; all months have an average precipitation of at least . Seasonal tropical forests with tropical monsoon climate, tropical monsoon or tropical savanna climate, savanna climates are sometimes included in the broader definition. Tropical rainforests ecosystems are distinguished by their consistent, high temperatures, exceeding monthly, and substantial annual rainfall. The abundant rainfall results in nutrient-poor, leached soils, which profoundly affect the flora and fau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Venezuela
Venezuela, officially the Bolivarian Republic of Venezuela, is a country on the northern coast of South America, consisting of a continental landmass and many Federal Dependencies of Venezuela, islands and islets in the Caribbean Sea. It comprises an area of , and its population was estimated at 29 million in 2022. The capital and largest urban agglomeration is the city of Caracas. The continental territory is bordered on the north by the Caribbean Sea and the Atlantic Ocean, on the west by Colombia, Brazil on the south, Trinidad and Tobago to the north-east and on the east by Guyana. Venezuela is a presidential republic consisting of States of Venezuela, 23 states, the Venezuelan Capital District, Capital District and Federal Dependencies of Venezuela, federal dependencies covering Venezuela's offshore islands. Venezuela is among the most urbanized countries in Latin America; the vast majority of Venezuelans live in the cities of the north and in the capital. The territory o ...

Endemism
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 b ...

Venezuelan Coastal Range
The Venezuelan Coastal Range ( or ), also known as Venezuelan Caribbean Mountain System (), is a mountain range system and one of the eight natural regions of Venezuela, that runs along the central and eastern portions of Venezuela's northern coast. The range is a northeastern extension of the Andes, and is also known as the Maritime Andes. It covers around 48,866 km2, being the 4th largest natural region in Venezuela. Geography The Coastal Range consists of two parallel ranges, which run east and west along the coast of the Caribbean Sea. The Cojedes River separates the western end of the Coastal Range from the Cordillera de Mérida to the southeast. The range is divided into eastern and western sections by the wide bay between Cape Codera and Cumaná. Serranía del Litoral—Serranía del Interior In the eastern section of the range, the parallel ranges are known as the Serranía del Litoral, which runs along the Caribbean coast, and the Serranía del Interior to the south ...

Bombacoideae
Bombacoideae is a subfamily of the mallow family, Malvaceae. It contains herbaceous and woody plants. Their leaves are alternate, commonly palmately lobed, with small and caducous stipules. The flowers are hermaphroditic and actinomorphic; the calyx has 5 sepals united at the base, which are not accompanied by an epicalyx (involucel). The corolla has 5 free petals and an androecium of numerous stamens, typically with free filaments which are not fused in a staminal tube (column). The pollen is smooth and the ovary superior and pluricarpellate. The fruits are schizocarpous or capsular. Genera Classification Some taxa in this subfamily were previously grouped under the now-obsolete family Bombacaceae, as recent phylogenetic research has shown that Bombacaceae as traditionally circumscribed (including tribe Durioneae) is not a monophyletic group. '' Camptostemon'', '' Lagunaria'', '' Pentaplaris'' and '' Uladendron'' might more appropriately be placed in Malvoideae, as might the ...

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 ...

Yaracuy
Yaracuy (, ;) is one of the 23 States of Venezuela, states of Venezuela. Yaracuy is located in the Central-Western Region, Venezuela. It is bordered by Falcón State, Falcón in the north, in the west by Lara State, Lara, in the south by Portuguesa (state), Portuguesa and Cojedes State, Cojedes and in the east by Cojedes (state), Cojedes and Carabobo State, Carabobo. The geography of state is mountainous, the Andes range ends there, and the Coastal Range begins. It is split by two mountainous systems, the Sierra de Aroa on the North and the Sierra de Nirgua. In between lies the agricultural land drained by the Yaracuy River. Most cities and towns are in this valley, including the capital city. The Cerro María Lionza Natural Monument is located in Chivacoa. Yaracuy is known as the Louisiana of Venezuela, due to the practices of witchcraft, occultism and the practice of religions such as African diaspora religions, voodoo, very similar to Louisiana Voodoo.

Henri François Pittier
Henri François Pittier de Fabrega (August 13, 1857 in Bex, Switzerland – January 27, 1950 in Caracas, Venezuela) was a Swiss-born geographer and botanist who started Venezuelan National Park history. Biography He graduated as an engineer from the University of Jena and moved to Costa Rica in 1887, where he founded the Physical Geographic Institute and an herbarium. With Théophile Alexis Durand he edited the exsiccata-like series ''Plantae Costaricenses exsiccatae''. Pittier collected fungi in Costa Rica which was published as a paper in 1896 by Marietta Hanson Rousseau and Elisa Caroline Bommer, and collected spiders that were detailed or described by A. Getaz in a paper in 1893, and collected at various dates and locations in the prior four years. That latter work also mentions a specimen from Greytown (Nicaragua) also collected by H.Pittier. Pittier arrived in Venezuela in 1917, where he classified more than 30,000 plants and devoted many years to studying the flora a ...

Trees Of Venezuela
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 of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Henri François Pittier
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
