Today i visited the place once again. Found three saplings, 6 to 8 inches high, that i think of the same species. But, before i proceed please let me give a bit more details of those saplings. Those three saplings were planted in line with a gap of about 2 ft each. It is as if they were planted by someone, but only three?!
Attaching the images of leaves from those plants/saplings. Please note :-
Later in order to take more photographs i visited that particular place a number of times but the plant seemed to be vanished. I also searched the surrounding area, there was no trace of a second individual.
