Branched bartonia (ssp. paniculata) COSEWIC assessment and status report: chapter 4
Distribution
Global range
Bartonia paniculata ssp. paniculata has a wide range in the eastern United States from New England south to Louisiana and Texas (see Figure 2).
Canadian range
In Canada it occurs only in southÂcentral Ontario (see Figure 3). At the time of the original status report (White, 1991), there were five stations known: four in Muskoka District and one just north of Muskoka in Parry Sound District. Since that time, two additional stations have been found, one is within two kilometres of an existing site (Site 6) and the other is 11 kilometres from Site 6. Both new sites are well within the previously known Ontario range. Site 2 population was confirmed in 1991 but could not be relocated in 2002 and may have disappeared.
