Kaulf.
Georg Friedrich Kaulfuss (8 April 1786 – 9 December 1830) was a professor at Halle. He described the pteridophytes collected by Adelbert von Chamisso, and he named the fern ''Cibotium chamissoi'' after him. The genus '' Kaulfussia'' is named for Kaulfuss. In 1816, he obtained his doctorate from the University of Halle, where in 1823, he became a full professor of botany. Plants Named by Kaulfuss More than 200 plant names were published by Kaulfuss. Tropicos.org. Missouri Botanical Garden. 01 Feb 2012 These include the genera: * *'' Cochlidium'' * *'' Balantium'' * Plant families named by Kaulfuss include: * |
Cyatheaceae
The Cyatheaceae are a family of ferns, the scaly tree ferns, one of eight families in the order Cyatheales in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Alternatively, the family may defined much more broadly (Cyatheaceae '' sensu lato'') as the only family in the Cyatheales, with the PPG I family treated as the subfamily Cyatheoideae. The narrower circumscription is used in this article. The family includes the world's tallest tree ferns, which reach heights up to 20 m. They are also very ancient plants, appearing in the fossil record in the late Jurassic, though the modern genera likely appeared in the Cenozoic. Cyatheaceae are the largest family of tree ferns, including about 640 species. Cyatheaceae and Dicksoniaceae, together with Metaxyaceae and Cibotiaceae, do not form a strongly supported monophyletic group and could be paraphyletic, but several individual subgroups are well supported as being monophyletic. Cyatheaceae are leptosporangiate fer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grammitis
''Grammitis'' (dwarf polypody) is a genus of ferns in the family Polypodiaceae, subfamily Grammitidoideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). It had formerly been placed in the family Grammitidaceae, but this family is no longer recognized by most authors because phylogenetic analyses of DNA sequences have shown that it is embedded in Polypodiaceae.Harald Schneider, Hans-Peter Krier, Rosemary Wilson, and Alan R. Smith. 2006. "The Synammia Enigma: Evidence for a Temperate Lineage of Polygrammoid Ferns (Polypodiaceae, Polypodiidae) in Southern South America". ''Systematic Botany'' 31(1):31-41. The delimitation of ''Grammitis'' was drastically narrowed in the first decade of the 21st century. It now contains about 25 species. In 2003, a study of the distribution of grammitid ferns placed 11 species in the New World, 7 in Africa, and 4 in the Pacific.Barbara S. Parris. 2003.

Marattiaceae
Marattiaceae is the only family of extant (living) ferns in the order Marattiales. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), Marattiales is the only order in the subclass Marattiidae. The family has six genera and about 110 species. Many are different in appearance from other ferns, having large fronds and fleshy rootstocks. Description The Marattiaceae diverged from other ferns very early in their evolutionary history and are quite different from many plants familiar to people in temperate zones. Many of them have massive, fleshy rootstocks and the largest known fronds of any fern. The Marattiaceae is one of two groups of ferns traditionally known as eusporangiate ferns, meaning that the sporangium is formed from a group of cells as opposed to a leptosporangium in which there is a single initial cell. At least two genera, ''Angiopteris'' and ''Marattia'', have been reported to undergo monoplastidic meiosis rather than polyplastidic meiosis, and are the ...

Botany
Botany, also called plant science, is the branch of natural science and biology studying plants, especially Plant anatomy, their anatomy, Plant taxonomy, taxonomy, and Plant ecology, ecology. A botanist or plant scientist is a scientist who specialises in this field. "Plant" and "botany" may be defined more narrowly to include only land plants and their study, which is also known as phytology. Phytologists or botanists (in the strict sense) study approximately 410,000 species of Embryophyte, land plants, including some 391,000 species of vascular plants (of which approximately 369,000 are flowering plants) and approximately 20,000 bryophytes. Botany originated as history of herbalism#Prehistory, prehistoric herbalism to identify and later cultivate plants that were edible, poisonous, and medicinal, making it one of the first endeavours of human investigation. Medieval physic gardens, often attached to Monastery, monasteries, contained plants possibly having medicinal benefit. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halle (Saale)
Halle (Saale), or simply Halle (), is the second largest city of the States of Germany, German state of Saxony-Anhalt. It is the sixth-most populous city in the area of former East Germany after (East Berlin, East) Berlin, Leipzig, Dresden, Chemnitz and Magdeburg as well as the List of cities in Germany by population, 31st-largest city of Germany. With around 226,000 inhabitants, it is less populous than the state capital, Magdeburg. With Leipzig, the largest city of Saxony, Halle forms the polycentric metropolitan area, polycentric Leipzig-Halle conurbation. Leipzig/Halle Airport, Leipzig/Halle International Airport lies between the two cities, in Schkeuditz. The Leipzig-Halle conurbation is at the heart of the larger Central German Metropolitan Region. Halle has been known by many names throughout its history. From the 15th to the 17th century: ''Hall in Sachsen''. From then until the beginning of the 20th century, the name Halle an der Saale was used, and still remains a more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pteridophyte
A pteridophyte is a vascular plant (with xylem and phloem) that reproduces by means of spores. Because pteridophytes produce neither flowers nor seeds, they are sometimes referred to as " cryptogams", meaning that their means of reproduction is hidden. They are also the ancestors of the plants we see today. Ferns, horsetails (often treated as ferns), and lycophytes ( clubmosses, spikemosses, and quillworts) are all pteridophytes. However, they do not form a monophyletic group because ferns (and horsetails) are more closely related to seed plants than to lycophytes. "Pteridophyta" is thus no longer a widely accepted taxon, but the term ''pteridophyte'' remains in common parlance, as do ''pteridology'' and ''pteridologist'' as a science and its practitioner, for example by the International Association of Pteridologists and the Pteridophyte Phylogeny Group. Etymology The name ''Pteridophyte'' is a Neo-Latin compound word created by English speakers around 1880. It is for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adalbert Von Chamisso
Adelbert von Chamisso (; 30 January 1781 – 21 August 1838) was a German poet, writer and botanist. He was commonly known in French as Adelbert de Chamisso (or Chamissot) de Boncourt, a name referring to the family estate at Boncourt. Life The son of Louis Marie, Count of Chamisso, by his marriage to Anne Marie Gargam, Chamisso began life as Louis Charles Adélaïde de Chamissot at the ''château'' of Boncourt at Ante, in Champagne, France, the ancestral seat of his family. His name appears in several forms, one of the most common being ''Ludolf Karl Adelbert von Chamisso.''Rodolfo E.G. Pichi Sermolli. 1996. ''Authors of Scientific Names in Pteridophyta''. Royal Botanic Gardens, Kew. In 1790, the French Revolution drove his parents out of France with their seven children, and they went successively to Liège, the Hague, Würzburg, and Bayreuth, and possibly Hamburg, before settling in Berlin. There, in 1796, the young Chamisso was fortunate in obtaining the post of pag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaulfussia
''Christensenia'' is a genus of ferns in the botanical family Marattiaceae. The genus is confined to the Indo-Malayan region. The basal chromosome number for this genus is 2n=80. ''Christensenia'' is unique in the Marattiaceae, because of its reticulate venation, palmately arranged leaves and radial synangia. ''Christensenia'' produces enormous amounts of spores, up to 7,000 spores per sporangium. The presence of a radial synangium is an archaic character, very similar to some of the fossil Asterothecaceae/ Psaroniaceae, such as '' Scolecopteris''. ''Christensenia'' itself has no fossil record.

University Of Halle
Martin Luther University Halle-Wittenberg (), also referred to as MLU, is a public research university in the cities of Halle and Wittenberg. It is the largest and oldest university in the German state of Saxony-Anhalt. MLU offers German and international (English) courses leading to academic degrees such as BA, BSc, MA, MSc, doctoral degrees, and habilitation. The university was created in 1817 through the merger of the University of Wittenberg (founded in 1502) and the University of Halle (founded in 1694). MLU is named after Protestant reformer Martin Luther, who was a professor in Wittenberg. Today, the university campus is located in Halle, while ''Leucorea Foundation'' in Wittenberg serves as MLU's convention centre. History University of Wittenberg (''Universität Wittenberg'') was founded in 1502 by Frederick the Wise, Elector of Saxony to propagate the principles of Renaissance humanism. The foundation of the university was heavily criticized, especially wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dicksonia
''Dicksonia'' is a genus of tree ferns in the order Cyatheales. It is regarded as related to '' Cyathea'', but is considered to retain more primitive traits, dating back at least to the Jurassic and Cretaceous periods. The fossil record includes stems, pinnules, and spores. The genus contains 20–25 species, distributed from Mexico to Argentina, Brazil, Uruguay and Chile, St. Helena, New Zealand, New Caledonia, Australia, Indonesia, New Guinea, and the Philippines. New Guinea has the greatest diversity, with five species. Species of ''Dicksonia'' found in cultivation include: *''D. antarctica'', soft tree fern *''D. fibrosa'', woolly tree fern *''D. squarrosa'', rough or slender tree fern The genus was first described by Charles Louis L'Héritier de Brutelle in 1788.
