William West (botanist)
William West, FLS (22 February 1848 – 14 May 1914) was an English pharmacist, botanist, microscopist and writer, particularly noted for his studies of freshwater algae. His sons, both botanists, were William West Jr with whom he did fieldwork, and George Stephen West with whom West co-wrote botanical publications for more than 20 years. West was born in Leeds in the West Riding of Yorkshire. He was the son of a cloth-dresser and a dressmaker, and his training as a pharmacist was probably via an apprenticeship in a chemist shop, which would have involved the study of plants. For most of his life, West ran his own pharmacy in Bradford. He was self-trained in botany, and for some years he ran a microscopy partnership with Jean Claudius Tempère, selling slides. In 1881 West published his first academic paper, "Bryological Notes". For much of his writing career, he collaborated with his son George Stephen, writing papers for journals, and publishing books.

George Stephen West
George Stephen West (20 April 1876 – 7 August 1919), ARCS, FLS, was a British botanist, a specialist in phycology and protistology, a botanical illustrator and a writer. With his father. botanist William West (West, 1848–1914), he collaborated on numerous scientific books. West's brother was the botanist William West Jr (W. West, 1875–1901), who assisted his father with fieldwork. West was professor of natural history at the Royal Agricultural College at Cirencester, then was based for the rest of his life at the University of Birmingham, where he was elected Mason Professor of Botany, following the retirement of William Hillhouse. While there, he enlarged the botany department. One of his students was Muriel Bristol. He was a Fellow of the Linnean Society of London, and president of Birmingham Natural History and Philosophical Society. West was married with two sons who were young children when he died at age 43 of double pneumonia. He left behind numerous scie ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should cl ...

Green Algae
The green algae (singular: green alga) are a group consisting of the Prasinodermophyta and its unnamed sister which contains the Chlorophyta and Charophyta/ Streptophyta. The land plants (Embryophytes) have emerged deep in the Charophyte alga as sister of the Zygnematophyceae. Since the realization that the Embryophytes emerged within the green algae, some authors are starting to properly include them. The completed clade that includes both green algae and embryophytes is monophyletic and is referred to as the clade Viridiplantae and as the kingdom Plantae. The green algae include unicellular and colonial flagellates, most with two flagella per cell, as well as various colonial, coccoid and filamentous forms, and macroscopic, multicellular seaweeds. There are about 22,000 species of green algae. Many species live most of their lives as single cells, while other species form coenobia (colonies), long filaments, or highly differentiated macroscopic seaweeds. A few other org ...

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group ( taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopod ...

Chlamydomonadales
Chlamydomonadales, also known as Volvocales, are an order of flagellated or pseudociliated green algae, specifically of the Chlorophyceae.See the NCBIbr>webpage on Chlamydomonadales Data extracted from the Chlamydomonadales can form planar or spherical colonies. These vary from '' Gonium'' (four to 32 cells) up to '' Volvox'' (500 cells or more). Each cell has two flagella, and is similar in appearance to ''Chlamydomonas'', with the flagella throughout the colony moving in coordination. Both asexual and sexual reproduction occur. In the former, cells divide until they form new colonies, which are then released. In the smaller forms, typically all cells are involved, but larger forms have anterior vegetative and posterior reproductive cells. Sexual reproduction varies from isogamy (both genders produce flagellated gametes of equal size) to oogamy (one gender produces a much larger, nonmotile gamete). The classification of the Chlamydomonadales varies. Very often they are t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
