Dawson Turner
Dawson Turner (18 October 1775 – 21 June 1858) was an English banker, botanist and antiquary. He specialized in the botany of cryptogams and was the father-in-law of the botanist William Jackson Hooker and of the historian Francis Palgrave. Life Turner was the son of James Turner, head of the Gurney and Turner's Yarmouth Bank; see also: and Elizabeth Cotman, the only daughter of the mayor of Great Yarmouth, Yarmouth, John Cotman. He was educated at North Walsham Grammar School (now Paston College), Norfolk and at Barton Bendish as a pupil of the botanist Robert Forby. He then went to Pembroke College, Cambridge, where the Master was his uncle Rev. Joseph Turner. He however left without a degree due to his father's terminal illness. In 1796, he joined his father's bank. After becoming a banker, he took a more intensive interest in botany in leisure time, collecting specimens in the field. In 1794, Turner offered to help James Sowerby with specimens. Turner published a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Algae
Brown algae (: alga) are a large group of multicellular algae comprising the class (biology), class Phaeophyceae. They include many seaweeds located in colder waters of the Northern Hemisphere. Brown algae are the major seaweeds of the temperate and polar regions. Many brown algae, such as members of the order Fucales, commonly grow along rocky seashores. Most brown algae live in marine environments, where they play an important role both as food and as a potential habitat. For instance, ''Macrocystis'', a kelp of the order Laminariales, may reach in length and forms prominent underwater kelp forests that contain a high level of biodiversity. Another example is ''Sargassum'', which creates unique floating mats of seaweed in the tropical waters of the Sargasso Sea that serve as the habitats for many species. Some members of the class, such as kelps, are used by humans as food. Between 1,500 and 2,000 species of brown algae are known worldwide. Some species, such as ''Ascophyllum ...

Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is often based in Latin. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including s ...

Desmarestia
''Desmarestia'' is a genus of brown algae found worldwide. It is also called acid weed, acid kelp, acidweed, ', sea sorrel, (), ', mermaid's hair, landlady's wig, or '. However, 'sea sorrel' can also specifically refer to ''Desmarestia viridis''. Members of this genus can be either annual or perennial. Annual members of this genus store sulfuric acid in intracellular vacuoles. When exposed to air they release the acid, thereby destroying themselves and nearby seaweeds in the process. They are found in shallow intertidal zones. Ingesting sulfuric acid can cause severe digestive disturbances. but since sulfuric acid tastes extremely sour, members of the genus are unlikely to be eaten in harmful quantities. The genus was named in honor of Anselme Gaëtan Desmarest.
