Smooth-stem aster is lumped together with purple-stem aster by many authorities. It seems like there is a lot of difference between plants like this and purple-stems at the other extreme. The problem is that there's so many intermediate plants that it's hard to draw a clear boundary. One result is a lack of published material about S. firmum that would tell us where it grows. The known list should probably be a lot longer. So far this wetland species is listed for GA, IA, MI, MN, MO, NE, OH, AB, MB, ON, and SK. Ives Fen Preserve, Lenawee Co MI, 9/16/11.
