Physocarpus opulifolius var. opulifolius

From Flora of Indiana (1940) by Charles C. Deam

Generally local to very local:in all parts of the state. It generally grows along streams a few feet above the water level, sometimes higher up on the banks, and rarely in crevices at the tops of cliffs. I once found it in a marsh along Pigeon River west of Mongo, in Lagrange County, where it was common.
