The Jamaican tangelo, also known by proprietary names ugli fruit (pronounced "ugly") and uniq fruit (pronounced "unique"), is a citrus fruit that arose on the island of Jamaica through the natural hybridization of a tangerine or orange with a grapefruit (or pomelo), and is thus a tangelo. The original tree is believed to have been a hybrid formed from varieties of Seville orange, grapefruit and tangerine.
As a hybrid species, it is usually represented as Citrus reticulata × paradisi.
