Consider the following statements:

  1. 1.Moringa (drumstick tree) is a leguminous evergreen tree.
  2. 2.Tamarind tree is endemic to South Asia.
  3. 3.In India, most of the tamarind is collected as minor forest produce.
  4. 4.India exports tamarind and seeds of moringa.
  5. 5.Seeds of moringa and tamarind can be used in the production of biofuels.

Which of the statements given above are correct?

Answer & explanation

Answer: (b) 3, 4 and 5

UPSC's key marks statements 3, 4 and 5 correct, while 1 and 2 are wrong: moringa is a deciduous tree of its own family, not a legume, and tamarind is not endemic to South Asia, having originated in Madagascar (Spices Board).

  • ✗ 1. Moringa (Moringa oleifera) is a small deciduous tree of the family Moringaceae, so it is neither a legume nor evergreen.
  • ✗ 2. The Spices Board says tamarind originated in Madagascar and is now cultivated widely in India and other countries, so it is not endemic to South Asia.
  • ✓ 3. Tamarind, with seeds and de-seeded, is on the Ministry of Tribal Affairs' list of minor forest produce with a minimum support price, the gathering of which is a livelihood for tribal collectors.
  • ✓ 4. UPSC's official key treats this statement as correct; we could not confirm the detail from an official source, so we do not explain it here.
  • ✓ 5. UPSC's official key treats this statement as correct; we could not confirm the detail from an official source, so we do not explain it here.

Remember · Moringa is a deciduous Moringaceae tree, not a legume; tamarind originated in Madagascar and is a listed minor forest produce with an MSP.
