Question: Where was the surgeon and naturalist who described the Chaulmoogra odorata tree in 1815 educated? Passage:This paper caused some confusion. Mouat indicated that the oil was the product of a tree Chaulmoogra odorata, which had been described in 1815 by William Roxburgh, a surgeon and naturalist, while he was cataloging the plants in the East India Company’s botanical garden in Calcutta. This tree is also known as Gynocardia odorata. For the rest of the 19th century, this tree was thought to be the source of the oil. In 1901, Sir David Prain identified the chaulmoogra seeds of the Calcutta bazaar and of the Paris and London apothecaries as coming from Taraktogenos kurzii, which is found in Burma and Northeast India. The oil mentioned in the Ayurvedic texts was determined to be from the tree Hydnocarpus wightiana, known as Tuvakara in Sanskrit and chaulmugra in Hindi and Persian.
