I think we saw this plant at what I'm calling 1st Forrest, when we were going on about how Douglas Justice was lying to us in his blog about a maple being nearby, which we later found at the next Forrest Trail sign farther down Lower Asian Way. Now I see that it's curved trail and there are two Forrest Trail locations on Lower Asian Way. Anyway, the plant - the leaves have remarkably big serrations, and they are very regular. Branching is opposite. We didn't find a label, and it has a kind-of creepy weed look to it. Is it meant to be there?
