This unidentified flower has small yellow buds at the end of its thin stem. It reminded me of a flower that is an important plot device in a movie called Stardust. In the movie, a witch gives a man a flower that she says will give him good luck. It turns out that the flower is enchanted to ward off evil magic. I doubt this flower will provide the same effects, but its still comforting to see on the way to statistics class.
