"cross between tangerine and sour orange," 1926, from French clémentine (1902). Originally an accidental hybrid said to have been discovered by (and named for) Father Clement Rodier in the garden of his orphanage in Misserghin, near Oran, Algeria. Introduced into U.S. and grown at Citrus Research Center in Riverside, Calif., as early as 1909. Earlier the word was used as an adjective in reference to other Clements, especially of the edition of the Vulgate issued due to Pope Clement V (1309-14).
