Biodiversity, plants & animals Medium

Consider the following:

  1. 1.Cashew
  2. 2.Papaya
  3. 3.Red sanders

How many of the above trees are actually native to India?

Answer & explanation

Answer: (a) Only one

Only red sanders is Indian by origin: it grows wild in a small tract of the southern Eastern Ghats. Cashew and papaya are both American plants brought to India in the sixteenth and seventeenth centuries, even though India is now a leading grower of both.

  • ✗ 1. Cashew (Anacardium occidentale) is a native of eastern Brazil. The Portuguese introduced it to India in the 16th century, first in Goa, from where it spread along the coasts.
  • ✗ 2. Papaya came from the New World (the Americas) along with the pineapple, tomato, potato and chilli during the Mughal period, as NCERT's history text notes.
  • ✓ 3. Red sanders (Pterocarpus santalinus, 'rakta chandan') is native to southern India, found on dry, rocky hills of the south-eastern peninsula; it is prized and heavily smuggled for its red heartwood.

Remember · Red sanders = native, endemic to the southern Eastern Ghats (mainly Andhra Pradesh). Cashew (Brazil) and papaya (tropical America) were introduced by the Portuguese.
