These pictures could be better but show the features of the inflorescence that help distinguish this species from other Sanicula spp.

This species is similar to S. trifoliata which differs in that the sepals of the fruit are 2-2.5 mm long and exceed the bristles of the fruit at maturity; in addition S. trifoliata has staminate flowers on slender pedicels that exceed the bristles of the fruit, a characteristic that can be useful for identification if the fruits are not mature.
