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, sensu lato. Different classifications have alternatively assigned them to anywhere from a single species, C. japonica, to numerous species representing each cultivar. Recent genomic analysis would define three pure species, Citrus hindsii, C. margarita and C. crassifolia, with C. x japonica being a hybrid of the last two.
Citrus is a genus of flowering trees and shrubs in the rue family, Rutaceae. Plants in the genus produce citrus fruits, including important crops such as oranges, lemons, grapefruits, pomelos, and limes. The genus Citrus is native to South Asia, East Asia, Southeast Asia, Melanesia, and Australia. Various citrus species have been used and domesticated by indigenous cultures in these areas since ancient times. From there its cultivation spread into Micronesia and Polynesia by the Austronesian expansion ; and to the Middle East and the Mediterranean via the incense trade route, and onwards to Europe and the Americas.
Calamansi, also known as kalamansi, calamondin, Philippine lime, or Philippine lemon, is an economically important citrus hybrid predominantly cultivated in the Philippines. It is native to the Philippines, parts of Indonesia, Malaysia, and Brunei, as well as parts of southern China and Taiwan.
Citrus myrtifolia, the myrtle-leaved orange tree, is a species of Citrus with foliage similar to that of the common myrtle. It is a compact tree with small leaves and no thorns which grows to a height of three metres (10 ft) and can be found in Malta, Libya, the south of France, and Italy.
The tangelo, Citrus × tangelo, is a citrus fruit hybrid of a Citrus reticulata variety, such as mandarin orange or tangerine, and a Citrus maxima variety, such as a pomelo or grapefruit. The name is a portmanteau of 'tangerine' and 'pomelo'.
The trifoliate orange, Citrus trifoliata, is a member of the family Rutaceae. Whether the trifoliate oranges should be considered to belong to their own genus, Poncirus, or be included in the genus Citrus is debated. The species is unusual among citrus for having deciduous, compound leaves and pubescent (downy) fruit.
The mandarinquat, also misleadingly called orangequat, is any cross between a mandarin and a kumquat. Mandarinquats are members of the citrofortunella group.
An orange is a fruit of various citrus species in the family Rutaceae ; it primarily refers to Citrus × sinensis, which is also called sweet orange, to distinguish it from the related Citrus × aurantium, referred to as bitter orange. The sweet orange reproduces asexually ; varieties of the sweet orange arise through mutations.
Walter Tennyson Swingle was an American agricultural botanist who contributed greatly to the classification and taxonomy of citrus.
Citropsis articulata, known commonly as the African cherry orange, West African cherry orange, Uganda cherry orange, and locally as omuboro, is a species of flowering plant in the citrus family, Rutaceae. It is native to tropical West Africa.
Aurantioideae is the subfamily within the rue and citrus family (Rutaceae) that contains the citrus. The subfamily's center of diversity is in the monsoon region of eastern Australasia, extending west through South Asia into Africa, and eastwards into Polynesia.
Citrus macroptera, also known as shatkora or hatkhoracabuyao, Melanesian papeda, or wild orange, is a semi-wild species of citrus native to the Sylhet region of Bangladesh.
Citreae is one of the two tribes of the flowering plant family Rutaceae, subfamily Aurantioideae, the other being Clauseneae.
The kishu mikan is a hybrid variety of mikan, or mandarin orange, found in Southern China and also grown in Japan. It is more closely related to the mandarin orange than to the common sweet orange.
Clymenia is a small genus of flowering plants in the family Rutaceae with two species. The genus is often included in Citrus.
Clausena is a genus of flowering plants in the citrus family, Rutaceae. It was first defined by the Dutch botanist Nicolaas Laurens Burman in 1768. It is distributed in Africa, southern Asia, Australia, and the Pacific Islands.
Citrus taxonomy refers to the botanical classification of the species, varieties, cultivars, and graft hybrids within the genus Citrus and related genera, found in cultivation and in the wild.
Citrus rootstock are plants used as rootstock for citrus plants. A rootstock plant must be compatible for scion grafting, and resistant to common threats, such as drought, frost, and common citrus diseases.
Atalantia is a genus of flowering plants in the citrus family, the Rutaceae.
