Walther Otto Müller
Walther Otto Müller, also Otto Müller, (20 June 1833 – 17 July 1887, in Gera) was a German botanist and gardner.Frahm & Eggers: ''Lexikon deutschsprachiger Bryologen.'' He was mainly interested in Cryptogamae, in particular lichen and mosses. Müller was the author of some books and several articles in scientific and botanical journals. He monochrome illustrated at least one. He collected plants, lichen and mosses for herbaria to sell the exsiccates as loose-leaf-collections. Several of these exsiccatae issued by him are known, among them ''Die Cladoniaceen von Nord-Deutschland, herausgegeben von W. O. Müller''.Triebel, D. & Scholz, P. 2001–2024 ''IndExs – Index of Exsiccatae''. Botanische Staatssammlung München: http://indexs.botanischestaatssammlung.de. – München, Germany. The topography of the Gera region provided flora and fauna from lowland and highland at one rich spot. Some of his specimens are housed at the Natural History Museum, London, British Museum. Some ...

Digitalis Purpurea Koehler Drawing
''Digitalis'' ( or ) is a genus of about 20 species of herbaceous perennial plants, shrubs, and Biennial plant, biennials, commonly called foxgloves. ''Digitalis'' is native to Europe, Western Asia, and northwestern Africa. The flowers are tubular in shape, produced on a tall spike, and vary in colour with species, from purple to pink, white, and yellow. The name derives from the Latin word for "finger". The genus was traditionally placed in the figwort family, Scrophulariaceae, but phylogenetic research led taxonomists to move it to the Veronicaceae in 2001. More recent phylogenetic work has placed it in the much enlarged family Plantaginaceae. The best-known species is the common foxglove, ''Digitalis purpurea''. This biennial is often grown as an ornamental plant due to its vivid flowers, which range in colour from various purple tints through pink and purely white. The flowers can also possess various marks and spottings. Other garden-worthy species include ''D. ferrugi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diatomaceae
A diatom (Neo-Latin ''diatoma'') is any member of a large group comprising several genera of algae, specifically microalgae, found in the oceans, waterways and soils of the world. Living diatoms make up a significant portion of Earth's biomass. They generate about 20 to 50 percent of the oxygen produced on the planet each year, take in over 6.7 billion tonnes of silicon each year from the waters in which they live, and constitute nearly half of the organic material found in the oceans. The shells of dead diatoms are a significant component of marine sediment, and the entire Amazon basin is fertilized annually by 27 million tons of diatom shell dust transported by transatlantic winds from the African Sahara, much of it from the Bodélé Depression, which was once made up of a system of fresh-water lakes. Diatoms are unicellular organisms: they occur either as solitary cells or in colonies, which can take the shape of ribbons, fans, zigzags, or stars. Individual cells range in s ...
