Identification of this species from other Sanicula in eastern North America can be difficult. The following combination of features separate it: leaves are divided into 5 (usually) to 7 (occasionally) leaflets; styles are much longer than the calyx; there are up to 12-25 stamens per umbellet; flowers and anthers are yellowish-green, with petals much longer than sepals.^[4][5]
