Wisconsin's Orange Lilies

I am having an identity crisis. No, not my own, but of these beautiful lilies I found near Lone Rock, Wisconsin.

Roadside Michigan Lily
Michigan Lily
These were a bit different than the lovely orange Michigan Lily / Turk's-Cap Lily I found a few years ago, a bit close to home.

The Michigan Lilies have a lighter center, and the filaments are shorter and thicker. The beauty above is a much finer and more graceful of a flower, and is the same deep orange through to the center. Maybe it's just an older blossom, but I can't find much of a match for this year's discovery on the web. So until I learn otherwise, I'll call 'em both Michigan Lilies.
