Consider the following statements: ​ 1. Moringa (drumstick tree) is a leguminous evergreen tree. ​ 2. Tamarind tree is endemic to South Asia. ​ 3. In India, most of the tamarind is collected as minor forest produce. ​ 4. India exports tamarind and seeds of moringa. ​ 5. Seeds of moringa and tamarind can be used in the production of biofuels. ​ Which of the statements given above are correct? ​

Statements 1 and 2 are false, so the answer is B (3, 4 and 5).

• Statement 1 is wrong. Moringa oleifera belongs to the family Moringaceae, not Leguminosae, even though its pods look like beans. It is generally treated as a deciduous or semi-evergreen tree, not a strictly evergreen legume.
• Statement 2 is wrong. Tamarind (Tamarindus indica) is native to tropical Africa and was introduced to South Asia long ago. It is not endemic to South Asia.
• Statement 3 is right. Tamarind is listed among minor forest produce, and much of the national supply comes from trees on forest fringes, village commons and homesteads.
• Statement 4 is right. India is a major exporter of tamarind pulp and seeds, and moringa pods and seeds also move in export trade.
• Statement 5 is right. Moringa seed oil and tamarind seed kernel are both researched and used as feedstock for biodiesel and other biofuels.

The core concept is the classification of plant species and their economic uses, which links to NTFP policy, the Forest Rights Act and the bioeconomy. For Mains, the same theme supports discussion of how minor forest produce can raise tribal incomes through value addition.

Trap: Aspirants often accept statement 1 because moringa pods look like legume pods, and they assume tamarind is a native Indian tree because it is so common in the country.
