DistributionSouthern Coastal Plain only. The gap between the inner and outer portions appears to be real, but this plant ought to be present in Robeson County.

Extremely small range -- Coastal Plain of southeastern NC and disjunctly to southwestern SC.
AbundanceVery rare to rare, but can be abundant at a few sites. This is a State Endangered species.
HabitatClay-based Carolina bays (with Pond Cypress [Taxodium ascendens] canopy), natural depression ponds. In all cases, periodically inundated for months at a time. Robeson County has a great number of clay-based Carolina bays, but it has yet to be found in them, but more survey is needed -- especially as the species was described after a major inventory of the county was done.
PhenologyFlowering and fruiting August-October.
IdentificationBay Boneset is very similar to White-bracted Thoroughwort (E. leucolepis), but with narrower leaves that tend to angle upward (usually strongly) rather than lie horizontal. The inflorescences tend to have fewer branches and flowering heads. Leaves are less than 4.5 mm wide vs. more than 5 mm wide in White-bracted Thoroughwort, and seeds are 1.6-2.3 mm long vs. 2.2-3.5 mm long in that species.
Taxonomic CommentsRecently described by Schilling et al. (2007).

Other Common Name(s)Bay Eupatorium, Bay Thoroughwort, Swamp Justiceweed. The use of "Thoroughwort" rather than Boneset would be more consistent with similar species, but the authors of the paper suggested Bay Boneset as a common name.
