Vaccinium macrocarpon Aiton. Cranberry, Large Cranberry. Phen: May-Jul; Aug-Nov. Hab: Mountain bogs, low pocosins with deep peat, interdunal swales. Dist: Unlike the circumboreal V. oxycoccus Linnaeus, V. macrocarpon is limited to North America. It ranges as a native plant from NL (Newfoundland) west and south to s. ON, MN, ne. IL, n. IN, n. and c. OH, PA, and NJ, extending south along the Appalachians as a disjunct rarity through WV, w. VA, and ne. and se. TN to w. NC, and south along the outer Coastal Plain as a disjunct rarity in e. MD, se. VA, and ne. and se. NC. The occurrence in the inner Coastal Plain (fall-line sandhills) along the Little River in Cumberland County, NC is questionably native.
