Kumquats, or cumquats in Australian English, are a group of small fruit-bearing trees in the flowering plant 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.

Clausena anisata (Willd.) Hook.f. ex Benth. is a deciduous shrub or small tree, belonging to the Rutaceae or Citrus family, and widespread in the Afrotropical realm or Sub-Saharan Africa, but absent from the drier regions. It is also found in tropical and South-East Asia, growing in India and Sri Lanka and extending as far as Queensland in north-eastern Australia and some Pacific islands. It is cultivated in Malaysia and Indonesia. As with other plants useful to mankind its large range of medicinal properties has led to a global distribution and its growth wherever the climate is suitable. It grows in higher-rainfall regions in savanna, thickets, riverine forest, disturbed areas and secondary forest, up to an altitude of 3000 m. The leaves, which are foetid when bruised, give rise to the common name 'Horsewood' or the more descriptive Afrikaans common name 'Perdepis', meaning 'horse urine'.
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.
