I think Hedychium gardnerianum (Zingiberaceae).
I have another two pictures of this flower. the single flower i post here was taken at another place where i did not see the whole inflorescence. I wish i could capture the habitat.
The photo no.1 is Hedychium spicatum Buch-Ham. ex Sm. and 2. is H. calcaratum A.S. Rao and D.M. Verma.
