Randonia
''Randonia'' is a monotypic genus of flowering plants belonging to the family Resedaceae. The only species is ''Randonia africana''. Its native range is Sahara desert in northern Africa. It is found in Algeria, Egypt, Libya, Mauritania, Morocco and Tunisia. The genus name of ''Randonia'' is in honour of Jacques Louis Randon (1795–1871), a French military and political leader, also Marshal of France and governor of Algeria. The Latin specific epithet In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, bot ... of ''africana'' means coming from Africa. The genus and the species were first described and published in Bull. Soc. Bot. France Vol.6 on pages 391-392 in 1859.

Jacques Louis Randon
Jacques Louis César Alexandre Randon, 1st Count Randon (25 March 1795 – 16 January 1871) was a French military and political leader, also Marshal of France and governor of Algeria. Early life He was born at Grenoble in Dauphiné, of a Protestant family. Later in life he converted to Catholicism, under the influence of his second wife. He was a nephew of General Jean-Gabriel, Count Marchand, Also a Revolutionary Antoine-Joseph Barnave was a first cousin of his mother.

Resedaceae
Resedaceae is a family of mostly herbaceous dicotyledonous plants comprising 107 known species in 8 to 12 genera: *''Borthwickia'' - 1 species, sometimes placed in its own family Borthwickiaceae *''Caylusea'' - 3 species *'' Forchhammeria'' - 10 species *''Homalodiscus'' - 2 species *''Neothorelia'' - 1 species *'' Ochradenus'' - 4 species *'' Oligomeris'' - 3 species *'' Randonia'' - 1 species *'' Reseda'' - ca 55 species *''Sesamoides'' - 1 species *'' Stixis'' - 7 species *'' Tirania'' 1 species Taxonomy Roman natural phylosopher Gaius Plinius Secundus or Pliny the Elder, who lived in the first century, is attributed to have used the name ''Reseda'' for the first time in writing. But he must have used it for another plant, because the medial effect of healing swellings and inflamations that he described, could not be reproduced from ''Reseda'' by later researcher. The British botanist Samuel Frederick Gray erected the family Resedaceae in 1821, based on the type genus ''Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coss
The kos (Hindi: कोस), also spelled ''coss'', ''koss'', ''kosh'', ''krosh'', and ''krosha'', is a unit of measurement which is derived from a Sanskrit term, क्रोश ''krośa'', which means to "call", as the unit was supposed to represent the distance at which another human could be heard. It is an ancient Indian subcontinental standard unit of distance, in use since at least 4 BC. According to the ''Artha-śāstra'', a ''krośa'' or ''kos'' is about 3000 meters or 1.8 miles. Another conversion is based on the Mughal emperor Akbar, who standardized the unit to 5000 '' guz'' in the Ain-i-Akbari. The British in India standardized Akbar's ''guz'' to 33 inches, making the ''kos'' approximately 4191 meters. Another conversion suggested a ''kos'' to be approximately 2 English miles. Arthashastra Standard units The ''"Arthashastra'': Chapter XX. "Measurement of space and time", authored in 4th century BC by Chanakya (Vishnugupta Kauṭilya), sets this standard breakup of ...

Ernest Saint-Charles Cosson
Ernest Saint-Charles Cosson (22 July 1819 – 31 December 1889) was a French botanist born in Paris. Cosson is known for his botanical research in North Africa, and during his career he participated in eight trips to Algeria. In several of these he was accompanied by Henri-René Le Tourneux de la Perraudière (1831-1861), whom he honoured in the naming of several species and genera (e.g., ''Perralderia'', '' Galium perralderii''). In 1863 he was elected president of the ''Société botanique de France'', and from 1873 to 1889, he was a member of the ''Académie des sciences''. In 1882 Jules Ferry, as Minister of Public Instruction, decided to create a mission to explore the Regency of Tunisia. The expedition was headed by Cosson and included the botanist Napoléon Doumet-Adanson and other naturalists. In 1884 a geological section under Georges Rolland was added to the Tunisian Scientific Exploration Mission. Rolland was assisted by Philippe Thomas from 1885 and by Georges Le Mesl ...

Monotypic Genus
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 trichopoda.' ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. The term "angiosperm" is derived from the Greek words ἀγγεῖον / ('container, vessel') and σπέρμα / ('seed'), meaning that the seeds are enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Angiosperms are distinguished from the other seed-producing plants, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the common ance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marshal Of France
Marshal of France (french: Maréchal de France, plural ') is a French military distinction, rather than a military rank, that is awarded to generals for exceptional achievements. The title has been awarded since 1185, though briefly abolished (1793–1804) and for a period dormant (1870–1916). It was one of the Great Officers of the Crown of France during the and Bourbon Restoration, and one of the Grand Dignitaries of the Empire during the First French Empire (when the title was Marshal of the Empire, not Marshal of France). A Marshal of France displays seven stars on each shoulder strap. A marshal also receives a baton: a blue cylinder with stars, formerly fleurs-de-lis during the monarchy and eagles during the First French Empire. The baton bears the Latin inscription of ', which means "terror in war, ornament in peace". Between the end of the 16th century and the middle of the 19th century, six Marshals of France were given the even more exalted rank of Marshal G ...

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus '' Homo'' and within this genus to the species '' Homo sapiens''. '' Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plants Described In 1859
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 abili ...

Flora Of North Africa
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurm ...
