A phylogenetic study showed that it is a cross between sour orange (Citrus aurantium) and citron (Citrus medica).

Its fruit, called lemon, is consumed in cooking because of its sour taste. It contains a lot of vitamin C, which is why it was used in the navy to prevent scurvy (a disease caused by vitamin C deficiency).
