The sweet lime, Citrus limettioides Tan. (syn. C. lumia Risso et Poit.), is called limettier doux in French; lima dulce in Spanish; mitha limbu, mitha nimbu, or mitha nebu, in India (mitha meaning sweet); quit giây in Vietnam; limûn helou, or succari in Egypt; laymûn-helo in Syria and Palestine. It is often confused with the sweet lemon, C. limetta Tan., (q.v. under LEMON) which, in certain areas, is referred to as sweet lime. In some of the literature, it is impossible to tell which fruit is under discussion.
