Sanicula marilandica Linnaeus. Maryland Sanicle, Black Snakeroot. Phen: May-Jun; Jul-Aug. Hab: Mesic to dry-mesic nutrient-rich forests. Dist: QC and NL (Newfoundland) west to BC, south to Panhandle FL, se. LA, NM, and WA.
Origin/Endemic status: Native
Taxonomy Comments: The Coastal Plain populations (designated as var. petiolulata by Fernald) are somewhat disjunct from the main range of distribution, occur in rather different (more acidic) habitats, and warrant additional study. The primary morphological difference indicated by Fernald (1950) is that var. petiolulata has "the leaflets of 1 or 2 lower cauline leaves on petiolules 1.5-5 cm long" (vs. sessile or short-petiolulate).
