TAMARIND (TAMARINDUS INDICA) (IMLI)
Tamarind (Tamarindus indica) is a leguminous tree in the family Fabaceae indigenous to tropical Africa. The genus Tamarindus is a monotypic taxon, having only a single species.
The tamarind tree produces pod-like fruit, which contain an edible pulp that is used in cuisines around the world. Other uses of the pulp include traditional medicine and metal polish. The wood can be used for woodworking, and tamarind seed oil can be extracted from the seeds. Because of the tamarind's many uses, cultivation has spread around the world in tropical and subtropical zones.
The tamarind is a long-lived, medium-growth shrub, which attains a maximum crown height of 12 to 18 metres (39 to 59 ft). The crown has an irregular, vase-shaped outline of dense foliage. The tree grows well in full sun. It prefers clay, loam, sandy, and acidic soil types, with a high resistance to drought and aerosol salt (wind-borne salt as found in coastal areas).
The evergreen leaves are alternately arranged and pinnately lobed. The leaflets are bright green, elliptic-ovular, pinnately veined, and less than 5 cm (2.0 in) in length. The branches droop from a single, central trunk as the tree matures, and are often pruned in agriculture to optimize tree density and ease of fruit harvest. At night, the leaflets close up.
Origin
Tamarindus indica is probably indigenous to tropical Africa, but has been cultivated for so long on the Indian subcontinent that it is sometimes reported to be indigenous there, where it is known as imli in Hindi-Urdu. It grows wild in Africa in locales as diverse as Sudan, Cameroon, Nigeria, and Tanzania. In Arabia, it is found growing wild in Oman, especially Dhofar, where it grows on the sea-facing slopes of mountains.
Fruit
The fruit is an indehiscent legume, sometimes called a pod, 12 to 15 cm (4.7 to 5.9 in) in length, with a hard, brown shell.
The fruit has a fleshy, juicy, acidulous pulp. It is mature when the flesh is coloured brown or reddish brown. The tamarinds of Asia have longer pods (containing six to 12 seeds), whereas African and West Indian varieties have shorter pods (containing one to six seeds). The seeds are somewhat flattened, and a glossy brown. The fruit is best described as sweet and sour in taste, and is high in tartaric acid, sugar, B vitamins, and, unusually for a fruit, calcium.
