Lily in the Jewelweed

Wile walking through the lower part of Vale (near Nott Terrace if anyone wants to visit) I was looking at the jewelweed (also called touch-me-not) to see if the seed pods had begun ripening yet (they haven't). I couldn't believe my eyes when I came across this gorgeous lily tucked in the midst of all the jewelweed. I have no idea what species the lily is, but I later found several more examples.
