White Lily but with ruffled amarylis looking leaves

Hello guys.. I need help to identify this plant. I know it's a kind of lily, but not too sure because the leaves are different then what I expect.
This one is has white flower with some nice smell.
Appreciate your help.

This doesn't look like a lily to me. What does the base or stem of the plant look like?

 

I don't know if this helps but yours does look a little like this Ginger plant.

and has similar foliage.

 

My opinion is that....
it is a crinum jagus amaryllis, smells like a gardenia.

 

Thanks a lot for the info guys.
I think chocolate got this one right. I've search for the Crinum jagus. It does look quite the same, but I also think maybe it's Crinum Schmidtii species. It got somekind like vanilla scent. Yay..I think I've got new plant for my garden Thanks..Have a nice day!
