Puzzled

Beautiful day which was spent with grand kids, grand kids ballgames and mowing the yard, so was only able to get outside around the house for a few minutes at dusk. What puzzles me is the red nodding trillium that are found in my immediate neighborhood. My home is at 3000 feet and the elevation around my house goes up to 3400 feet in areas that I visit looking for wild flowers,wild turkey and morels. The only trillium that I find near here are Painted Trillium in the woods behind my home and a red trillium that nods, often below the leaves. There are no white trillium nor, normal red trillium. They are blooming now and it reminds me that I have never been sure if it is a local quirk of Red Trillium or a red variety of one of the nodding or bent trillium's. I wish I was good at keying wildflowers, but it always leaves me uncertain. This one has a dark red ovary, green sepals and off white stamens. My best guess is that the red ovary makes it Red Trillium (Trillium erectum). Any Thoughts?
