Alwin Berger
Alwin Berger (28 August 1871 – 20 April 1931) was a German botanist best known for his contribution to the nomenclature of succulent plants, particularly agaves and cacti. Born in Germany he worked at the botanical gardens in Dresden and Frankfurt. From 1897 to 1914 he was curator of the Giardini Botanici Hanbury, the botanical gardens of Sir Thomas Hanbury at La Mortola, near Ventimiglia in northwestern Italy, close to the border with France. After working in Germany from 1914 to 1919, Berger studied in the United States for three years, before spending his final years as director of the department of botany of the natural history museum in Stuttgart His main work, ''Die Agaven'', published in 1915, described 274 species of agave, divided into 3 subgenera, '' Littaea'', '' Euagave'' and ''Manfreda''. He also recognised a new genus of cactus, ''Roseocactus'', in 1925. The genera ''Bergerocactus'' (''Cactaceae'') and ''Bergeranthus'' (''Mesembryanthemaceae'') are named in ...

Martin Heinrich Gustav Schwantes
Martin Heinrich Gustav Schwantes (18 September 1881 – 1960) was a German archaeologist and botanist specialist of Aizoaceae (Mesembryanthemaceae). Life and work Schwantes was born in Bleckede and died in Hamburg. The Duvensee paddle is the preserved part of a Mesolithic spade paddle, which was found during archaeological excavations of a Mesolithic dwelling area at Duvensee near Klinkrade (Herzogtum Lauenburg) Schleswig-Holstein, Germany, in 1926 by Schwantes.

Plant
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ...

Lithops
''Lithops'' is a genus of succulent plants in the ice plant family, Aizoaceae. Members of the genus are native to southern Africa. The name is derived from the Ancient Greek words () 'stone' and () 'face', referring to the stone-like appearance of the plants. They avoid being eaten by blending in with surrounding rocks and are often known as pebble plants or living stones. The formation of the name from the Ancient Greek ''-ops'' means that even a single plant is called a Lithops. Description Individual ''Lithops'' plants consist of one or more pairs of bulbous, almost fused leaves opposite to each other and hardly any stem. The slit between the leaves contains the meristem and produces flowers and new leaves. The leaves of ''Lithops'' are mostly buried below the surface of the soil, with a partially or completely translucent top surface known as a leaf window which allows light to enter the interior of the leaves for photosynthesis. During winter a new leaf pair, or occa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aizoaceae
The Aizoaceae, or fig-marigold family, is a large family of dicotyledonous flowering plant Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants th ...s containing 135 genus, genera and about 1800 species. They are commonly known as ice plants or carpet weeds. They are often called vygies in South Africa and New Zealand. Highly Succulent plant, succulent species that resemble stones are sometimes called mesembs. Description The family Aizoaceae is widely recognised by taxonomists. It once went by the botanical name "Ficoidaceae", now disallowed. The APG II system of 2003 (unchanged from the APG system of 1998) also recognizes the family, and assigns it to the order Caryophyllales in the clade core eudicots. The APG II system also classes the former families Mesembryanthemaceae Fenzl, S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Alwin Berger
In biology, a taxon (back-formation from ''taxonomy''; plural 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. 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 set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
