Citrus Crassifolia
''Citrus crassifolia'', the Meiwa kumquat, is a species of kumquat; a type of citrus fruit in the genus ''Citrus'', family Rutaceae. It was first described by the American botanist Walter Tennyson Swingle in 1915 as ''Fortunella crassifolia''. Initially, ''C. crassifolia'' was described as a synonym of ''Citrus japonica''. However, recent phylogenetic analysis suggested that ''C. crassifolia'' is a single 'true' species. ''C. crassifolia'' was brought to Japan from China at the end of the 19th century. It is a hybrid of Nagami (''Citrus margarita'') and Marumi (''Citrus japonica ''Citrus japonica'', the round kumquat, Marumi kumquat, or Morgani kumquat, is a species of citrus fruit in the genus ''Citrus''.

It has seedy oval fruits and thick leaves and was characterized as a different species by Swingle. Its fruit is typically eaten skin and all. Refere ...

Walter Tennyson Swingle
Walter Tennyson Swingle (January 8, 1871 – January 19, 1952) was an American agricultural Botany, botanist who contributed greatly to the classification and citrus taxonomy, taxonomy of citrus. Biography Swingle was born in South Canaan, Canaan, Pennsylvania, and moved with his family to Kansas two years later. He graduated from the Kansas State University, Kansas State Agricultural College in 1890, and studied at the University of Bonn in 1895–96 and 1898. With William Ashbrook Kellerman he edited the exsiccata ''Kansas fungi'' (1889), a specimen series which is widely distributed in major herbarium, herbaria. Swingle married Lucie Romstaedt in 1901; she died in 1910. He married Maude Kellerman, daughter of William Ashbrook Kellerman, in 1915 and they had four children. He died in Washington, D.C., on January 19, 1952. In 1927, botanist Elmer Drew Merrill published ''Swinglea'', which is a genus of flowering plants from the Philippines, belonging to the family Rutaceae a ...

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 ...

Citrus Margarita
''Citrus margarita'', the oval kumquat or Nagami kumquat, is a species of kumquat; a type of citrus fruit in the genus ''Citrus'', family Rutaceae. Its epithet, margarita, is Latin for pearly. It is first described by the Portuguese botanist João de Loureiro in 1790, in his ''Flora cochinchinensis'' under the name ''Citrus margarita''. It is described again by the American botanist Walter Tennyson Swingle in 1915, as varieties of '' Citrus japonica''. However, recent phylogenetic analysis suggested that ''C. margarita'' is a single 'true' species. Description ''C. margarita'' grows tall. The branches have few, to no spines. It has simple, alternate leaves, which are dark green above, and pale below and have a leathery texture. They are lanceolate (narrow) with an obtuse tip. They grow to up to long, and wide. The axillary flowers are white with 5 sepals and 5 petals and 16-20 stamens. They can be single or in clusters, and have persistent styles, and deep seated oil glan ...

Plants Described In 1915
Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts, mosses, lycophytes, ferns, conifers and other gymnosperm ...
