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, Citrus japonica, to numerous species representing each cultivar. Recent genomic analysis defines three pure species, Citrus hindsii, C. margarita and C. crassifolia, with C. × 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 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 calamondin, Philippine lime, or Philippine lemon, is a citrus hybrid cultivated predominantly in the Philippines. It is native to the Philippines, parts of Indonesia, Malaysia, and Brunei, as well as parts of southern China and Taiwan.
Forsythia, is a genus of flowering plants in the olive family Oleaceae. There are about 11 species, mostly native to eastern Asia, but one native to southeastern Europe. Forsythia – also one of the plant's common names – is named after William Forsyth.
The limequat is a citrus hybrid that is the result of a cross between the Key lime and the kumquat, hybridized by Walter Tennyson Swingle in 1909.
Ampelopsis, commonly known as peppervine or porcelainberry, is a genus of climbing shrubs, in the grape family Vitaceae. The name is derived from the Ancient Greek: ἅμπελος (ampelos), which means "vine". The genus was named in 1803. It is disjunctly distributed in eastern Asia and eastern North America extending to Mexico. Ampelopsis is primarily found in mountainous regions in temperate zones with some species in montane forests at mid-altitudes in subtropical to tropical regions. Ampelopsis glandulosa is a popular garden plant and an invasive weed.
Lespedeza is a genus of some 45 species of flowering plants in the pea family (Fabaceae), commonly known as bush clovers or Japanese clovers (hagi). The genus is native to warm temperate to subtropical regions of eastern North America, eastern and southern Asia and Australasia.
Weigela is a genus of between six and 38 species of deciduous shrubs in the family Caprifoliaceae, growing to 1–5 m (3–15′) tall. All are natives of eastern Asia. The genus is named after the German scientist Christian Ehrenfried Weigel.
Cocculus is a genus of four species of woody vines and shrubs, native to tropical and subtropical regions of Africa and Asia.
Limonia acidissima is the only species within the monotypic genus Limonia. Common names for the species in English include wood-apple and elephant-apple. It is sometimes also called monkey fruit.
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.
Citrus macroptera, natively known as hatkhora or cabuyao, Melanesian papeda, or wild orange, is a semi-wild species of citrus native to the Sylhet region of Bangladesh and the Barak Valley Division of the Indian state of Assam.
Clymenia is a small genus of flowering plants in the family Rutaceae with two species. The genus is often included in Citrus.
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.
Procimequat is a triploid citrus hybrid or transgeneric hybrid, x Fortunella hindsii, in which the limequat that itself is a cross between lime and a round kumquat, was backcrossed with the primitive Hong Kong kumquat.
Eriocapitella japonica is a species of flowering plant in the buttercup family Ranunculaceae. The specific epithet japonica means "from Japan", which is a misnomer since the species is introduced in Japan. It is native to China, Taiwan, and Vietnam.
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.
Citrus margarita, the oval kumquat or Nagami kumquat, is a species of kumquat; a type of citrus fruit in the genus Citrus, family Rutaceae.
Citrus hindsii, the Hong Kong kumquat, is a species of kumquat; a type of citrus fruit in the genus Citrus, family Rutaceae. This specific name is first published in World Checklist of Seed Plants 3(1): 15 (1999). Recent phylogenetic analysis suggested that C. hindsii is a single 'true' species.
Citrus swinglei, the Malayan kumquat, is a species of kumquat; a type of citrus fruit in the genus Citrus, family Rutaceae. It was first described by Burkill ex Harms in 1931.
