Thanks Garg ji. The posted plant, clearly has a conspicuous ear-like structure (auriculate pseudo-stipule) at the base of each leaf stalk. Thus, as per keys, will be not *A. gigantea*. I suggest we also pay heed to the fruits which are different looking among the above listed species. Will return to this post when I find the plant in flowering as well as fruiting.
