LENTIL

(species Lens esculenta), small annual legume of the pea family (Leguminosae) and its lens-shaped edible seed, which is rich in protein and one of the most ancient of cultivated foods. Of unknown origin, the lentil is widely cultivated throughout Europe, Asia, and North Africa but is little grown in the Western Hemisphere. The seeds are used chiefly in soups and the herbage as fodder. Lentils are a good source of protein, vitamin B, iron, and phosphorus. The plant varies from 15 to 45 cm (6 to 18 inches) in height and has many long, ascending branches. The leaves are alternate, with six pairs of oblong-linear leaflets about 15 mm (0.5 inch) long and ending in a spine. Two to four pale blue flowers are borne in the axils of the leaves in June or early July. The pods are about 1520 mm long, broadly oblong, and slightly inflated and contain two seeds the shape of a doubly convex lens and about 46 mm in diameter. There are many cultivated varieties of the plant, differing in size, hairiness, and colour of the leaves, flowers, and seeds. The seeds may be more or less compressed in shape, and the colour may vary from yellow or gray to dark brown; they are also sometimes mottled or speckled. The lentil has been found in the lake dwellings of St. Peter's Island, Lake Biel, Switz., dating from the Bronze Age. The red pottage of lentils for which Esau sold his birthright (Genesis 25:3034) probably was made from the red Egyptian lentil. This lentil is cultivated in one or another variety in the Middle East, North Africa, and Europe along the Mediterranean coast and as far north as Germany, The Netherlands, and France. In Egypt, Syria, and other Middle Eastern countries, the parched seeds are sold in shops and are esteemed the best food to carry on long journeys.
