I thought we already had them! According to Wikipedia, "swamp oak" can refer to either Q. bicolor or Q. palustris, both of which are indigenous to northern Illinois. The latter I know as "pin oak" and it is the dominant oak species in the St Louis area (which is damn shame, because it's also one of the ugliest). And if I was going to react to that, I would've been miserable during my recent trip south when it was all in bloom, forcing my nephews to have to wash their hands every time they came inside.
