We learn through the speaker's revelation of her experiences with and memories of the casuarina tree in her yard that baboons play among its branches and kokilas (a Sanskrit name for the koel bird), a type of bird that is native to India, perch there. Likewise, the casuarina tree is a species that is native to the Indian subcontinent as well. Finally, though this alone would not be enough to make the claim, Toru Dutt—the poet—is a Bengali woman (and Bengal is a region of India).

Thus, we can reasonably determine that the casuarina tree is located in India. This conclusion is the result of factual knowledge of the species of tree and bird, which would seem to be corroborated by the biographical information about the poet. Otherwise, there are not a great many other clues about the location of the tree.

We know that it is draped in a "scarf" of red flowers, that the scarf looks like a "Python," that the tree is "hoar" (incredibly old) and that water lilies grow near it. Thus, it sounds like this is something of a warmer climate, which India has. The tree grows quite near the family home of the speaker, and she talks of generations getting to grow up and play under its branches, a tradition that she hopes will continue for many years more.
