No one has yet mentioned Lilium neilgherrense, the lily with the most southern natural distribution.The Kew List gives the name as L. wallichianum var. neilgherrense. I've never seen this lily, but ten years ago or so I was only about a day's drive from the Nilgiri Hills and was sooooo tempted to try to find it. I would like to see this one before i die! Two other to consider are Lilium alexandrae and L. nobilissimum. Jimj McKenney
