This is a very beautiful plant. The Turk's Cap Lily can be distinguished from the more common Lilium michiganense (Michigan Lily) as follows: 1) the former species is restricted to southern Illinois, although it may be introduced elsewhere; 2) some of the anthers of the former are greater than ½" long, while the anthers of the latter species are always less than ½" long; 3) the former has white bulbs, while the latter has yellow bulbs, and 4) the former species may have a conspicuous 6-pointed green star at the base of the flower, although this feature isn't always present in some local ecotypes. The stamens of Turk's Cap Lily are even more strongly exerted from the throat of the flower than is the case for the Michigan Lily, and it tends to be a taller, more robust plant.
