The cam sành (literally "terra-cotta orange") is a variety of citrus fruit similar to an orange, originating from Vietnam. The fruit may be easily recognized by its thick skin, which is typically bright green in color (although it may also be partly green and partly orange, or entirely orange), while its flesh is orange.
[edit] Scientific nomenclature
The cam sành's species is variously given as Citrus nobilis (mandarin orange),[1][2] Citrus reticulata,[3] or Citrus sinensis (sweet orange),[4] , though in reality it is a natural hybrid thereof: C. reticulata x C. sinensis (common name: king mandarin).[5][6] As such, it is related to the tangor, which is a hybrid of the mandarin orange and sweet orange.
[edit] Distribution
The tree was introduced to the United States in 1880, when the United States Minister to Japan John A. Bingham arranged for six cam sành fruits to be shipped from Saigon, Cochinchina, to Dr. H. S. Magee, a nurseryman in Riverside, California. In 1882, Magee sent two seedlings and budwood to J. C. Stovin in Winter Park, Florida.[7][8]
In Vietnam, the tree had been cultivated in the Bố Hạ region of Bac Giang Province, but had been eradicated due to the Citrus Greening Disease. Nowadays, cam sành is planted widely in the North of Vietnam (Hà Giang, Tuyên Quang, Yên Bái), as well as in several provinces of the Mekong Delta in the South, including Vĩnh Long, Cần Thơ, and Tiền Giang.
