This species is similar to S. canadensis which differs in that the sepals of the fruit are inconspicuous (0.6-1.5 mm) and do not exceed the bristles of the fruit at maturity; in addition S. candensis has staminate flowers that or more or less sessile, a characteristic that can be useful for identification if the fruits are not mature.
