Tangelo Citrus paradisi Å Citrus reticulata Tangelos are deliberate or accidental hybrids of any mandarin orange and the grapefruit or pummelo The first known crosses were made by Dr Walter T Swingle at Eustis Florida in 1897 and Dr Herbert J Webber at Riverside California in 1898 They are so unlike other citrus fruits that they have been set aside in a class by themselves designated Citrus X tangelo J Ingram H E Moore C X paradisi X C reticulata Tangelos range from the size of a standard sweet orange to the size of a grapefruit but are usually somewhat necked at the base The peel is fairly loose and easily removed The pulp is often colorful subacid of fine flavor and very juicy The trees are large more cold tolerant than the grapefruit but not quite as hardy as the mandarin Nucellar embryos are not uncommon in these hybrids and most of the cultivars are self sterile so a majority come true from seed
