The Cara cara navel, or re navel orange is an early-to-midseason navel orange believed to have developed as a cross between the Washington navel and the Brazilian Bahai navel . Discovered at the Hacienda de Cara Cara in Valencia, Venezuela in 1976 , the parentage is apparently uncertain enough to occasionally warrant the distinction of a mutation, with only the tree on which it was found--the Washington navel--being an accepted progenitor. Cara caras did not enter the U.S consumer produce market until the late 1980s and were carried only by specialty markets for many years thereafter.
