From Flora Novae Angliae dichotomous key

1.  Sanicula canadensis L. NC

Canada sanicle. 1a. Sanicula marilandica L. var. canadensis (L.) Torr. • CT, MA, NH, RI, VT. Rich, mesic forests, dry-mesic forests on sandy soils.

1a.  Umbellets of only one type usually present—those with both bisexaul and staminate flowers, those with only staminate flowers rare; umbellets with both types of flowers bearing 1–3 staminate flowers borne on pedicels up to 2 mm long [Fig. 355]; styles shorter than or equal in length to the calyx; triad of fruits mostly 7–9 mm wide … 1a. S. canadensis var. canadensis

1b.  Umbellets of both types sometimes present—those with both bisexual and staminate flowers and those with only staminate flowers; umbellets with both types of flowers bearing 3–15 staminate flowers borne on pedicels 2–3 mm long; styles ca. 1.5 times as long as the calyx; triad of fruits mostly 10–15 mm wide … 1b.

Native to North America?

Yes

Sometimes confused with

Sanicula trifoliata:
sepals 2–2.5 mm long, lanceolate, connivent into a beak and conspicuous in fruit, exceeding the bristles of the schizocarp, and carpellate flowers sessile (vs. S. canadensis, with sepals 0.6–1.5 mm long, subulate, inconspicuous in fruit, shorter than the bristles of the schizocarp, and carpellate flowers on pedicels 0.5–1 mm long).
