Citrus fruit Fruit lemon slices in four arrangements about Lemon Limes

emon, Citrus × limon, is a citrus tree, a hybrid of cultivated origin. The fruit are cultivated primarily for their juice, though the pulp and rind (zest) are also used, primarily in cooking or mixing. Lemon juice is about 5% citric acid, which gives lemons a sour taste.This is a small tree, grows to 6 m (20 ft) but usually smaller. The branches are thorny, and form an open crown. The leaves are elliptical-acuminate. Flowers are violet and streaked in the interior and white on the outside. On a lemon tree, flowers and ripe fruits can be found at the same time.The first description of the lemon, which had been introduced from India two centuries earlier, is found in Arabic writings from the 12th century. The origin of the name lemon is through Persian (لیمو Limu), from the Sanskrit nimbuka. They were cultivated in Genoa in the mid-fifteenth century, and appeared in the Azores in 1494. More recent research has identified lemons in the ruins of Pompeii. Lemons were once used by the British Royal navy to combat scurvy, as they provided a large amount of vitamin C. The Royal Navy originally thought lemons were overripe limes which they resemble and their sailors became known as limeys, not lemonies. See more at Wikipedia.org...
