Key lime
The Key lime has a longer shelf life than other limes, which is useful since refrigeration facilities are lacking in the country. The tree species of Indo-Malayan region was introduced to Mexico by Spanish Conquistadors after 1520. Now, 2,000,000 seedling trees are reported near Colima. However, there are very few varieties of the Key lime, except for several spineless selections, inasmuch as there is no great variation in the wild or under cultivation.
