Botanist
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning "pasture", " herbs" "grass", or " fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – edible, med ...

Bürgermeister
Burgomaster (alternatively spelled burgermeister, literally "master of the town, master of the borough, master of the fortress, master of the citizens") is the English form of various terms in or derived from Germanic languages for the chief magistrate or executive of a city or town. The name in English was derived from the Dutch ''burgemeester''. In some cases, Burgomaster was the title of the head of state and head of government of a sovereign (or partially or de facto sovereign) city-state, sometimes combined with other titles, such as Hamburg's First Mayor and President of the Senate). Contemporary titles are commonly translated into English as ''mayor''. Historical use * The title "burgermeister" was first used in the early 13th century. *In history (sometimes until the beginning of the 19th century) in many free imperial cities (such as Bremen, Hamburg, Lübeck etc.) the function of burgomaster was usually held simultaneously by three persons, serving as an executive co ...

Weimar
Weimar is a city in the state of Thuringia, Germany. It is located in Central Germany between Erfurt in the west and Jena in the east, approximately southwest of Leipzig, north of Nuremberg and west of Dresden. Together with the neighbouring cities of Erfurt and Jena, it forms the central metropolitan area of Thuringia, with approximately 500,000 inhabitants. The city itself has a population of 65,000. Weimar is well known because of its large cultural heritage and its importance in German history. The city was a focal point of the German Enlightenment and home of the leading figures of the literary genre of Weimar Classicism, writers Johann Wolfgang von Goethe and Friedrich Schiller. In the 19th century, noted composers such as Franz Liszt made Weimar a music centre. Later, artists and architects such as Henry van de Velde, Wassily Kandinsky, Paul Klee, Lyonel Feininger, and Walter Gropius came to the city and founded the Bauhaus movement, the most important German de ...

Schloss Belvedere, Weimar
The Baroque palace Schloss Belvedere on the outskirts of Weimar,The more famous Schloss Belvedere is located in Vienna. is a pleasure-house (''Lustschloss'') built for house-parties, built in 1724–1732 to designs of Johann August Richter and Gottfried Heinrich Krohne for Ernst August, Duke of Saxe-Weimar. The ''corps de logis'' is flanked by symmetrical pavilions. Today it houses part of the art collections of Weimar, with porcelains and faience, furniture and paintings of the eighteenth century. As the summer residence, its gardens, laid out in the French style in 1728–1748, were an essential amenity. A wing of the Orangery in the ''Schlosspark'' contains a collection of historical carriages. After 1811, much of the outer gardens was altered to conform to the English landscape garden style, as an ''Englischer Garten'', for Grand Duke Carl Friedrich, who died at Belvedere in 1853. The enriched collection of exotic plants was published as ''Hortus Belvedereanus'' in 1820. B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomic Authority
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolut ...

Dennstaedtia
''Dennstaedtia'' is a mostly tropical and subtropical genus of ferns described as a genus in 1801. Hayscented fern, or Cup ferns, are common names for some species in this genus. Its best-known member is probably the temperate North-American hay-scented fern, ''Dennstaedtia punctilobula'' (pictured in the taxobox), which forms extensive clonal ground-cover colonies on level surfaces in the Appalachian area. Some characteristics of Dennstaedtia:"Fronds homomorphic; stipe grooved above, hairy when young... lamina triangular to oblong, many times pinnate, usually densely hairy, especially on rachis... Veins free, pinnately branching, veinlet not reaching margin, with '' hydathode'' at apex. Sori orbicular, marginal, terminal on each veinlet, separate..."

Johann Jakob Bernhardi
Johann Jakob Bernhardi (1 September 1774, in Erfurt – 13 May 1850, in Erfurt) was a German doctor and botanist. Biography Johann J. Bernhardi studied Medicine and Botany at the University of Erfurt, and after graduation practiced medicine for a time in his native city. In 1799 he was named director of the botanical garden at ''Gartenstraße'', and in 1809 was appointed professor of botany, zoology, mineralogy and materia medica at the university. He served as director of the botanical garden until his death in 1850, being buried in the central avenue of this botanical garden. Throughout his life thanks to acquisitions and interchanges with other botanists, he assembled a considerable herbarium of 60,000 plants with specimens from North America, South America, Asia, and Africa. After his death this herbarium did not remain in Germany but due to the efforts of George Engelmann, who, in 1857, shortly after the death of Bernhardi bought the complete herbarium for the amount of 600 do ...

Dennstaedtiaceae
Dennstaedtiaceae is one of fifteen families in the order Polypodiales, the most derived families within monilophytes (ferns). It comprises 10 genera with ca 240 known species, including one of the world's most abundant ferns, ''Pteridium aquilinum'' (bracken). Members of the order generally have large, highly divided leaves and have either small, round intramarginal sori with cup-shaped indusia (e.g. ''Dennstaedtia'') or linear marginal sori with a false indusium formed from the reflexed leaf margin (e.g. ''Pteridium''). The morphological diversity among members of the order has confused past taxonomy, but recent molecular studies have supported the monophyly of the order and the family.Smith, A. R., K. M. Pryer, et al. (2006). "A classification for extant ferns." Taxon 55(3): 705-731 The reclassification of Dennstaedtiaceae and the rest of the monilophytes was published in 2006, so most of the available literature is not updated.
