Willdenow
Carl Ludwig Willdenow (22 August 1765 – 10 July 1812) was a German botanist, pharmacist, and plant taxonomist. He is considered one of the founders of phytogeography, the study of the geographic distribution of plants. Willdenow was also a mentor of Alexander von Humboldt, one of the earliest and best known phytogeographers. He also influenced Christian Konrad Sprengel, who pioneered the study of plant pollination and floral biology. Biography Willdenow was born in Berlin and studied medicine and botany at the University of Halle. After studying pharmaceutics at Wieglieb College, Langensalza and in medicine at Halle, he returned to Berlin to work at his father's pharmacy located in the Unter den Linden. His early interest in botany was kindled by his uncle J. G. Gleditsch and he started a herbarium collection in his teenage years. In 1794 he became a member of the Berlin Academy of Sciences. He was a director of the Botanical garden of Berlin from 1801 until h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Willdenowia (plant)
''Willdenowia'' is a small genus of flowering plants in the family Restionaceae described as a genus in 1790.Thunberg, Carl Peter. 1790. Kongliske Vetenskaps Academiens Nya Handlingar 11: 26 The entire genus is endemic to the fynbos of the Western Cape Province of South Africa. They are rhizomatous, tufted, dioecious perennials, generally with terete, branching stems (Restionaceae more often have simple stems). The leaf sheaths are convolute and persistent. The male flowers grow in numerous spikelets borne in panicled racemes subtended by caducous spathes. Each floret is subtended by a linear or setaceous caducous bract. There are six papery perianth segments, with the inner shorter than the outer. The anthers are oblong and apiculate and the ovaries are rudimentary. The female spikelets may be single or several. They are borne in spicate cymes subtended by a persistent spathe. The perianth usually has six unequal segments clasping the sessile or stipitate ovary, which usu ...

Alexander Von Humboldt
Friedrich Wilhelm Heinrich Alexander von Humboldt (14 September 17696 May 1859) was a German polymath, geographer, naturalist, explorer, and proponent of Romantic philosophy and science. He was the younger brother of the Prussian minister, philosopher, and linguist Wilhelm von Humboldt (1767–1835). Humboldt's quantitative work on botanical geography laid the foundation for the field of biogeography. Humboldt's advocacy of long-term systematic geophysical measurement laid the foundation for modern geomagnetic and meteorological monitoring. Between 1799 and 1804, Humboldt travelled extensively in the Americas, exploring and describing them for the first time from a modern Western scientific point of view. His description of the journey was written up and published in several volumes over 21 years. Humboldt was one of the first people to propose that the lands bordering the Atlantic Ocean were once joined (South America and Africa in particular). Humboldt resurrected t ...

Christian Konrad Sprengel
Christian Konrad Sprengel (22 September 1750 – 7 April 1816) was a German naturalist, theologist, and teacher. He is most famous for his research on plant sexuality. Sprengel was the first to recognize that the function of flowers was to attract insects, and that nature favoured cross-pollination. Along with the work of Joseph Gottlieb Kölreuter he set the foundations for the modern study of floral biology and anthecology, but his work was not widely recognized until Charles Darwin examined and confirmed several of his observations almost 50 years later; see Fertilisation of Orchids (1862). Life Sprengel was born in Brandenburg an der Havel in the Margraviate of Brandenburg. He was the 15th and the last son of a preacher Ernst Victor Sprengel and his second wife Dorothea Gnadenreich Schaeffer (died 1778). Ernst Victor's father had been an organist and he himself was a choir-master, teacher and later archdeacon. Christian Konrad was expected to continue the tradit ...

Selaginella Willdenowii
''Selaginella willdenowii'' is a species of vascular plant in the Selaginellaceae family. It is a spikemoss known by the common names Willdenow's spikemoss and peacock fern due to its iridescent blue leaves. Like other Selaginallales, it is fern ally and not a true fern. ''Selaginella willdenowii'' is sometimes spelt incorrectly as ''Selaginella willdenovii''. Description The blue iridescence is produced by thin-film interference Thin-film interference is a natural phenomenon in which light waves reflected by the upper and lower boundaries of a thin film interfere with one another, either enhancing or reducing the reflected light. When the thickness of the film is an ... produced by a thin layer of cells with lamellar structure in the upper cuticle of leaves. It is suggested that this adaptation reduces the effect of strong sun beams filtering through the canopy that would otherwise damage shade-adapted species. Blue iridescence is found also '' Selaginella uncinata'' an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berlin
Berlin is Capital of Germany, the capital and largest city of Germany, both by area and List of cities in Germany by population, by population. Its more than 3.85 million inhabitants make it the European Union's List of cities in the European Union by population within city limits, most populous city, as measured by population within city limits having gained this status after the United Kingdom's, and thus London's, Brexit, departure from the European Union. Simultaneously, the city is one of the states of Germany, and is the List of German states by area, third smallest state in the country in terms of area. Berlin is surrounded by the state of Brandenburg, and Brandenburg's capital Potsdam is nearby. The urban area of Berlin has a population of over 4.5 million and is therefore the most populous urban area in Germany. The Berlin/Brandenburg Metropolitan Region, Berlin-Brandenburg capital region has around 6.2 million inhabitants and is Germany's second-largest metropolitan reg ...

Herbarium
A herbarium (plural: herbaria) is a collection of preserved plant 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 taxa; some specimens may be types, some may be specimens distributed in series called exsiccatae. The same term 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 Hortorium) has occasionally been applied to a herbarium specialising in preserving material of horticultural origin. History The making of herbaria is an ancient phenome ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
