Aralia spinosa

I was working in Southwestern Indiana (Dubois County) in a woodland, when I came upon a stand of understory trees that looked from a distance like young Ailanthus altissima. They were spindly, with fat twigs, about fifteen feet max. When I got closer, I realized that they were Devils Walking Stick. It would have been fun to see the place in the summer, since I am not too familiar with this species.
