Description: Medium sized tree to 15-25ft. It is believed to be a hybrid between C. ichangensis and C. reticulata, but shows typical species-like propagation by seeds. The fruits are best known from the Tokushima prefecture of Japan, where the vast majority of supply is grown. Fruits generally ripen in the Fall, a bit earlier than many of the more common citrus fruits. The fruits grow to 1-1.5 ounces. In Japan, the fruit is prized alongside its cousin, the yuzu.
