It's a trillium because there are three of everything; leaves, petals, sepals and who knows what else. Once you know what you're looking for, it's not hard to spot them in the woods from those three leaves.
It has another name, which describes how it smells: Stinking Benjamin. I don't know who Benjamin was though!
