Cutleria (alga)
''Cutleria'' is a genus of brown algae (class Phaeophyceae), one of 2–6 genera in the order Cutleriales. AlgaeBase recognises 11 species in the genus. The genus was described circumscribed by Robert Kaye Greville in Algae Brit. Vol.44 on page 59 in 1830. The name of ''Cutleria'' is in honour of Catharine Cutler (who died 1866), an English botanist, who specialised in Marine Botany and worked in Sidmouth Sidmouth () is a town on the English Channel in Devon, South West England, southeast of Exeter. With a population of 12,569 in 2011, it is a tourist resort and a gateway to the Jurassic Coast World Heritage Site. A large part of the town h ..., Devon.

Robert Kaye Greville
Dr. Robert Kaye Greville FRSE FLS LLD (13 December 1794 – 4 June 1866) was an England, English mycologist, bryology, bryologist, and botanist. He was an accomplished artist and illustrator of natural history. In addition to art and science he was interested in causes like Abolitionism in the United Kingdom, abolitionism, capital punishment, keeping Sunday special and the temperance movement. He has a mountain in Queensland named after him. Biography Greville was born at Bishop Auckland, County Durham, Durham, but was brought up in Derbyshire by his parents Dorothy ( Chaloner) and Robert Greville. His father who liked to compose was the rector of St James' Church, Edlaston, the parish church in Edlaston in Derbyshire. Greville had an interest in natural history since he was very young, but he originally studied medicine. Realising that he did not need an income he discarded four years of medical education in London and Edinburgh and decided to concentrated on botany which ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), 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 taxonomy (biology), 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 ...

Brown Algae
Brown algae (singular: alga), comprising the class Phaeophyceae, are a large group of multicellular algae, including many seaweeds located in colder waters within the Northern Hemisphere. Brown algae are the major seaweeds of the temperate and polar regions. They are dominant on rocky shores throughout cooler areas of the world. 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. Kelp forests like these 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. Many brown algae, such as members of the order Fucales, commonly grow along rocky seashores. Some members of the class, such as kelps, are used by humans as food. Between 1,500 and ...

AlgaeBase
AlgaeBase is a global species database of information on all groups of algae, both marine and freshwater, as well as sea-grass. History AlgaeBase began in March 1996, founded by Michael Guiry. Text was copied from this source, which is available under Attribution 4.0 International (CC BY 4.0)licence. (Sehere. By 2005, the database contained about 65,000 names. In 2013, AlgaeBase and the Flanders Marine Institute (VLIZ) signed an end-user license agreement regarding the Electronic Intellectual Property of AlgaeBase. This allows the World Register of Marine Species (WoRMS) to include taxonomic names of algae in WoRMS, thereby allowing WoRMS, as part of the Aphia database, to make its overview of all described marine species more complete. Synchronisation of the AlgaeBase data with Aphia and WoRMS was undertaken manually until March 2015, but this was very time-consuming, so an online application was developed to semi-automate the synchronisation, launching in 2015 in conju ...

Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogenetics ...

Sidmouth
Sidmouth () is a town on the English Channel in Devon, South West England, southeast of Exeter. With a population of 12,569 in 2011, it is a tourist resort and a gateway to the Jurassic Coast World Heritage Site. A large part of the town has been designated a conservation area. History The origins of Sidmouth pre-date recorded history. The Sid valley has been in human occupation since at least the Iron Age as attested by the presence of Sidbury Castle, and possibly earlier given the presence of Bronze Age burial mounds on Gittisham Hill and Broad Down. The village of Sidbury itself is known to be Saxon in origin with the Church crypt dating to the seventh century. However, the Sid Valley was divided into two ecclesiastical land holdings, with Sidbury and Salcombe Regis being gifted by King Athelstan to Exeter Cathedral, and Sidmouth, which was part of the manor of Otterton, was gifted by Gytha Thorkelsdóttir (the mother of King Harold Godwinson) to the Benedicti ...
