Tamarind characteristics (Tamarindus indica)

Common Name: Indian Tamarind, Kilytree, Tamarind.

Its common name derives from the Arabic “tamari Hindi” which means “fruit of India.”

Scientific name: Tamarindus indica L.

Taxonomic synonym: Tamarindus officinalis.

Family: Fabaceae or Leguminosae. Tamarind (Tamarindus indica) is a monotypic species, meaning that there is only one species within the genus Tamarindus.

Habitat: Tropical plant, native to Africa and spread throughout the African continent. It grows wild in Sudan.

It is believed that the tree was introduced in Asia by Arab traders, and their distribution in America is due to the first shipments of slaves from East Africa.

Currently it is grown in India, the largest Asian producer of this plant, and in America (Mexico, Costa Rica, Puerto Rico).

Tamarind has adapted to seasonally dry regions of long duration. However, in humid tropical climates, this tree is poorly developed and often fails to bear fruit. It is sensitive to frost and drought resistant. It grows at altitudes up to 1,200 meters.

Botanical description of tamarind

Tamarind (Tamarindus indica L.) is an evergreen tree, slow growing, which can measure between 15 and 25 meters high.

This is a very long-living tree, with thick trunk that can reach a circumference of 7.5 meters. It has a rough bark, dark gray. It has deep roots and strong branches, flexible to withstand the winds (it is described that it resists hurricanes).

Its leaves (1) are alternate, glabrous, paripinnate, with 10 to 20 pairs of oblong leaflets, opposite, apex rounded, asymmetrical base and entire margin.

Flowers arranged in small clusters grow (2), hermaphrodite, yellowish, venation pink or orange (3). Individual flowers are about 2.5 centimeters in diameter. They have three stamens and five petals.

The tamarind tree produces fruits between 7 and 12 years old. It reproduces by seed. Berry production stabilizes at the age of 15. When the tree is reproduced vegetatively. Fruits appear when the tree is 3 to 5 years old, or so. The tree is productive up to 40 to 60 years.

Indehiscent fruits are pods (4) curved and with protuberances due to seed inside them. The are between 8 and 15 (to 20) centimeters long by 2 to 2.5 centimeters wide and about 1 centimeter thick. The pericarp is thin, tan or brown, brown or brown-gray, which becomes a brittle shell at fruit maturity.

As they mature, the pods are filled with a juicy pulp combined with fibers (mesocarp), acidified and brown or reddish brown. Inside, it has a leathery layer (endocarp), septate between the seeds.

Tamarind seeds (5) are hard, brown and wrapped in protective endocarp layer. A sheath generally contains between 2 and 10 seeds of 1 cm in diameter each.

Pod maduration occurs approximately 10 months after flowering.
