Branched bartonia (ssp. paniculata) COSEWIC assessment and status report: chapter 9

Special Significance of the Species

Bartonia paniculata ssp. paniculata is a rare plant of sphagnum bogs whose natural significance is largely unknown. The Canadian populations could have some biogeographical significance due to their position some 600 km from the previously known northern edge of the plant's range. The species is one of a number of so-called Atlantic Coastal Plain Species having disjunct populations in the Muskoka District of Ontario but with a main range along the Atlantic coastal plain.
