The sour lime (Citrus medica, variety acida) is much grown in a home way, as its acid fruits are used to the almost total exclusion of the lemon in frostless climes for cooling drinks and for all culinary uses. It is also shipped in quantity from south Florida and the West Indies to New York, Boston, and other Atlantic cities, but rarely reaches the Western States. Budded on Citrus trifoliata it has proven about as hardy as the orange, and some of the East Indian varieties have proven hardier in Florida. This fruit will grow on poorer, thinner soil than any of the other citrus fruits.
