Bergamot orange Bergamot orange Citrus bergamia, the bergamot orange (pronounced ), is a fragrant citrus fruit the size of an orange, with a yellow or green color similar to a lime, depending on ripeness. Genetic research into the ancestral origins of extant citrus cultivars found bergamot orange to be a probable hybrid of lemon and bitter orange. Extracts have been used to scent food, perfumes, and cosmetics. Use on the skin can increase photosensitivity, resulting in greater damage from sun exposure. The word bergamot is etymologically derived from the Italian word ""bergamotto"", ultimately of Turkish origin: "bey armudu" or "bey armut" ("prince's
Citrus taxonomy While the subgenera suggested by Tanaka proved similar to the phylogenetic divisions, Swingle's subgenera were polyphyletic, and hence do not represent valid taxonomy. Historical genera are also dubious. Kumquats had been placed in a separate genus "Fortunella", while two genera were suggested by Swingle for the Australian limes, "Microcitrus" and "Eremocitrus". However, genomic analysis has pointed to these groups nesting within the phylogenetic tree of the other citrus plants. Since their placement in distinct genera would make "Citrus" a paraphyletic grouping, it has been suggested that all of these are correctly members of a single genus, "Citrus". Similarly, genomic analysis
