Citrus Obovata
''Citrus obovata'', the Jiangsu kumquat or Fukushu kumquat, is a species of kumquat; a type of citrus fruit in the genus ''Citrus'', family Rutaceae. It was first described by the French biologist Constantine Samuel Rafinesque in 1838. It was described by Tanaka in 1927 as a new species as well as a synonym of ''Citrus japonica ''Citrus japonica'', the round kumquat, Marumi kumquat, or Morgani kumquat, is a species of citrus fruit in the genus ''Citrus''. It was first described by Carl Peter Thunberg in 1780 as ''Fortunella japonica''. ''C. japonica'' is a native specie ...''. However, recent phylogenetic analysis suggested that ''C. obovata'' should be classified as natural or horticultural hybrids. Today, ''C. obovata'' is ranked a 'true' species.

Constantine Samuel Rafinesque
Constantine Samuel Rafinesque-Schmaltz (; 22 October 178318 September 1840) was a French early 19th-century polymath born near Constantinople in the Ottoman Empire and self-educated in France. He traveled as a young man in the United States, ultimately settling in Ohio in 1815, where he made notable contributions to botany, zoology, and the study of Mound Builders, prehistoric earthworks in North America. He also contributed to the study of ancient Mesoamerican languages, Mesoamerican linguistics, in addition to work he had already completed in Europe. Rafinesque was an eccentric and erratic genius. He was an autodidact, who excelled in various fields of knowledge, as a zoologist, botanist, writer and Polyglot (person), polyglot. He wrote prolifically on such diverse topics as anthropology, biology, geology, and linguistics, but was honored in none of these fields during his lifetime. Indeed, he was an outcast in the American scientific community and his submissions were automati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chōzaburō Tanaka
, often Romanized as Tyôzaburô Tanaka (November 3, 1885 in Osaka – June 28, 1976), was a Japanese botanist and mycologist. He established one of the two major Biological classification, taxonomic classification systems for citrus and related genera currently in use, and is now considered to be a taxonomic "Lumpers and splitters#Lumping and splitting in biology, splitter". He is the author of 180 botanical names in the citrus family Rutaceae, including for example ''Citrus Hybrid name (botany), × latifolia'' (Persian lime) and ''Citrus tangerina'' (tangerine). Many of the species Tanaka described are still recognized, but his overall scheme is not supported by modern genetic research. With Yaichi Shimada, Tanaka issued and distributed specimens in a numbered series resembling an exsiccata under the title ''Flora of Taiwan. Collected and distributed by Prof. T. Tanaka and Y. Shimada''. Works * * See also * Citrus hybrids References * * Botanists with author abbr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kumquat
Kumquats ( ), or cumquats in Australian English, are a group of small, angiosperm, fruit-bearing trees in the family Rutaceae. Their taxonomy is disputed. They were previously classified as forming the now-historical genus ''Fortunella'' or placed within ''Citrus'', . Different classifications have alternatively assigned them to anywhere from a single species, ''Citrus japonica'', to numerous species representing each cultivar. Recent genomic analysis defines three pure species, ''Citrus hindsii'', ''Citrus margarita, C. margarita'' and ''Citrus crassifolia, C. crassifolia'', with ''C.'' × ''japonica'' being a Hybrid (biology), hybrid of the last two. The edible fruit closely resembles the Orange (fruit), orange (''Citrus x sinensis'') in color, texture, and anatomy, but is much smaller, being approximately the size of a large olive. The kumquat is a fairly cold-hardy citrus. Etymology The English word ''kumquat'' is a borrowing of the Cantonese (; zh, c=金橘), from "gol ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Citrus
''Citrus'' is a genus of flowering trees and shrubs in the family Rutaceae. Plants in the genus produce citrus fruits, including important crops such as oranges, mandarins, lemons, grapefruits, pomelos, and limes. ''Citrus'' is native to South Asia, East Asia, Southeast Asia, Melanesia, and Australia. Indigenous people in these areas have used and domesticated various species since ancient times. Its cultivation first spread into Micronesia and Polynesia through the Austronesian expansion (–1500 BCE). Later, it was spread to the Middle East and the Mediterranean () via the incense trade route, and from Europe to the Americas. Renowned for their highly fragrant aromas and complex flavor, citrus are among the most popular fruits in cultivation. With a propensity to hybridize between species, making their taxonomy complicated, there are numerous varieties encompassing a wide range of appearance and fruit flavors.

Rutaceae
The Rutaceae () is a family (biology), family, commonly known as the rueRUTACEAE in BoDD – Botanical Dermatology Database or citrus family, of flowering plants, usually placed in the order (biology), order Sapindales. Species of the family generally have flowers that divide into four or five parts, usually with strong scents. They range in form and size from Herbaceous plant, herbs to shrubs and large trees. The most economically important genus in the family is ''Citrus'', which includes the Orange (fruit), orange (''C.'' × ''sinensis''), lemon (''C.'' × ''limon''), grapefruit (''C.'' × ''paradisi''), and Lime (fruit), lime (various). ''Boronia'' is a large Australian genus, some members of which are plants with highly fragrant flowers and are used in commercial Essential oil, oil production. Other l ...

Taxa Named By Constantine Samuel Rafinesque
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
