Endangered Species

Podophyllum hexandrum (the Himalayan mayapple) is a medicinal herb of the Himalayas.
Its rhizome yields the resin podophyllin, used to remove benign growths such as certain kinds of warts and as the source of anti-cancer drugs.
Because of over-collection from the wild it has become one of the endangered species of Indian medicinal plants.
Ocimum (tulsi) and garlic are medicinal plants that are widely cultivated and are not endangered.
Nepenthes (the pitcher plant) is an endangered plant, but it is an insectivorous plant and not a medicinal plant.
So the endangered Indian medicinal plant is Podophyllum.

An endangered species is one that faces a high risk of extinction in the near future.
Bentinckia nicobarica is a palm endemic to the Nicobar Islands and is an endangered plant.
The red panda, found in the eastern Himalayas, is an endangered animal.
So both members of this pair are endangered organisms of India.
Tamarind, Cinchona (a cultivated plant) and banyan are common plants and are not endangered.
The rhesus monkey is a common animal, so that pair is ruled out as well.
So the pair representing endangered organisms is Bentinckia nicobarica and Red Panda.
