Astrocaryum Aculeatissimum
''Astrocaryum aculeatissimum'' ( syn. ''Astrocaryum ayri'' Mart., ''Toxophoenix aculeatissima'' Schott) is a palm native to Atlantic Coast restingas vegetation, which is an ecosystem of Atlantic Forest biome in Brazil. This plant has a commercial value because it has useful fibers which may be used to make production of broom A broom (also known as a broomstick) is a cleaning tool, consisting of usually stiff fibers (often made of materials such as plastic, hair, or corn husks) attached to, and roughly parallel to, a cylindrical handle, the broomstick. It is thus a ...s. The trunk of the tree is covered by rings of very sharp spines, believed by some biologists to have evolved as protection against the extinct Megatherium Giant Ground Sloth.

Heinrich Wilhelm Schott
Heinrich Wilhelm Schott (7 January 1794 – 5 March 1865) was an Austrian botanist. He is known for his extensive work on aroids ( Araceae). Biography Schott was born on 7 January 1794 in Brno, Moravia. He studied botany, agriculture and chemistry at the University of Vienna, where he was a pupil of Joseph Franz von Jacquin (1766–1839). He was a participant in the Austrian Brazil Expedition from 1817 to 1821. In 1828 he was appointed ''Hofgärtner'' (royal gardener) in Vienna, later serving as director of the Imperial Gardens at Schönbrunn Palace (1845). In 1852 he was in charge of transforming part of palace gardens in the fashion of an English garden. He also enriched the Viennese court gardens with his collections from Brazil. He was also interested in Alpine flora, and was responsible for development of the alpinum at Belvedere Palace in Vienna. In 2008, botanists P.C.Boyce & S.Y.Wong published '' Schottarum'', a genus of flowering plants from Borneo belonging to t ...

Broom
A broom (also known as a broomstick) is a cleaning tool, consisting of usually stiff fibers (often made of materials such as plastic, hair, or corn husks) attached to, and roughly parallel to, a cylindrical handle, the broomstick. It is thus a variety of brush with a long handle. It is commonly used in combination with a dustpan. A distinction is made between a "hard broom" and a "soft broom" and a spectrum in between. Soft brooms are used in some cultures chiefly for sweeping walls of cobwebs and spiders, like a " feather duster", while hard brooms are for rougher tasks like sweeping dirt off sidewalks or concrete floors, or even smoothing and texturing wet concrete. The majority of brooms are somewhere in between, suitable for sweeping the floors of homes and businesses, soft enough to be flexible and to move even light dust, but stiff enough to achieve a firm sweeping action. The broom is also a symbolic object associated with witchcraft and ceremonial magic. Etymology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medicinal Plants Of South America
Medicine is the science and practice of caring for patients, managing the diagnosis, prognosis, prevention, treatment, palliation of their injury or disease, and promoting their health. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others. Medicine has been practiced since prehistoric times, and for most of this time it was an art (an area of creativity and skill), frequently having connections to the religious and philosophical beliefs of local culture. For example, a medicine man would apply herbs and say prayers for heali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiber Plants
Fiber (spelled fibre in British English; from ) is a natural or artificial substance that is significantly longer than it is wide. Fibers are often used in the manufacture of other materials. The strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene. Synthetic fibers can often be produced very cheaply and in large amounts compared to natural fibers, but for clothing natural fibers have some benefits, such as comfort, over their synthetic counterparts. Natural fibers Natural fibers develop or occur in the fiber shape, and include those produced by plants, animals, and geological processes. They can be classified according to their origin: * Vegetable fibers are generally based on arrangements of cellulose, often with lignin: examples include cotton, hemp, jute, flax, abaca, piña, ramie, sisal, bagasse, and banana. Plant fibers are employed in the manufacture of paper and textile (cloth), and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trees Of Brazil
In botany, a tree is a perennial plant with an elongated Plant stem, stem, or trunk (botany), trunk, usually supporting Branch, branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only Bark (botany), woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller Arecaceae, palms, Cyatheales, tree ferns, Musa (genus), bananas, and bamboos. Trees are not a Monophyletic group, monophyletic taxonomic group but consist of a wide 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 trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of The Atlantic Forest
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) wa ...

Endemic Flora Of Brazil
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 becomi ...

Astrocaryum
''Astrocaryum'' is a genus of about 36 to 40 species of palms native to Central and South America and Trinidad. Description ''Astrocaryum'' is a genus of spiny palms with pinnately compound leaves–rows of leaflets emerge on either side of the axis of the leaf in a feather-like or fern-like pattern. Some species are single-stemmed, while others grow in multi-stemmed (caespitose) clumps. They are pleonanthic—they flower repeatedly over the course of their lifespan—and monoecious, meaning that there are separate male and female flowers, but individuals plants bear both types of flowers. Taxonomy History The type species, ''Astrocaryum aculeatum'', was first described by German botanist Georg Friedrich Wilhelm Meyer in 1818 based on a specimen from the Essequibo River in Guyana. Species One well known member of the genus is '' Astrocaryum vulgare'', typical in the Pará state of Brazil. '' Astrocaryum mexicanum'', a common palm of the Caribbean coast of Central America, is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megatherium Giant Ground Sloth
''Megatherium'' ( ; from Greek () 'great' + () 'beast') is an extinct genus of ground sloths endemic to South America that lived from the Early Pliocene through the end of the Late Pleistocene. It is best known for the elephant-sized type species ''Megatherium americanum'', primarily known from the Pampas, but ranging southwards to northernmost Patagonia and northwards to southern Bolivia during the late Middle Pleistocene and Late Pleistocene. Various other species belonging to the subgenus ''Pseudomegatherium'' ranging in size comparable to considerably smaller than ''M. americanum'' are known from the Andean region. The first (holotype) specimen of ''Megatherium'' was discovered in 1787 on the bank of the Luján River in what is now northern Argentina. The specimen was then shipped to Spain the following year wherein it caught the attention of the French paleontologist Georges Cuvier, who named the animal in 1796 and was the first to determine, by means of comparative anato ...

Fiber Crop
Fiber crops are field crops grown for their fibers, which are traditionally used to make paper, cloth, or rope. Fiber crops are characterized by having a large concentration of cellulose, which is what gives them their Strength of materials, strength. The fibers may be chemically modified, like in viscose (used to make rayon and cellophane). In recent years, materials science, materials scientists have begun exploring further use of these fibers in composite materials. Due to cellulose being the main factor of a plant fiber's strength, this is what scientists are looking to manipulate to create different types of fibers. Fiber crops are generally harvestable after a single growing season, as distinct from trees, which are typically grown for many years before being harvested for such materials as wood pulp fiber or Lagetta lagetto, lacebark. In specific circumstances, fiber crops can be superior to wood pulp fiber in terms of technical performance, Environmental degradation, en ...

Max Burret
Karl Ewald Maximilian Burret, commonly known as Max Burret (6 June 1883 – 19 September 1964) was a German botanist. Burret was born in Saffig near Andernach in the Kingdom of Prussia, Prussian Rhine Province. He originally studied law at Lausanne and Munich at the instigation of his father. Burret had a greater interest in natural science than in law, and he eventually abandoned his law studies to conduct botany, botanical research in Berlin, where he earned a Ph.D. in 1909 for his Taxonomy (biology), taxonomic thesis, and quickly became one of Germany's most prominent botanists. Burret participated in many botanical science organizations in Germany, taking up leadership positions, such as assistant at the Berlin Botanical Museum and Garden from 1909 to 1911, as well as botanical assistant and lecturer at the Botanical Institute of the Agricultural College in Berlin in 1911 through 1921. In 1922 he was appointed custodian of the Botanical Museum and Garden in Berlin, and l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
