Author(de Candolle) Torrey & A. Gray
DistributionCoastal Plain and Sandhills, though lacking records for the northern portions. Ranges barely into the eastern edge of the Piedmont.

Coastal Plain, southeastern NY to northern FL and LA; disjunct to central TN.
AbundanceGenerally common in the southern part of the Coastal Plain, and fairly common in the central portions. Most numerous in areas where moist Longleaf Pine (Pinus palustris) stands are present. The State Rank should be moved to S5.
HabitatMoist to mesic (or dry) sandy soils of Longleaf Pine-Wiregrass savannas and flatwoods, blackwater streamhead ecotones, depression ponds and meadows (where seasonally inundated). Extends into dry and mesic pine uplands.
PhenologyFlowering and fruiting August-October.
IdentificationThis familiar wetland species grows 1.5-2.5 feet tall, with relatively few leaves and a relatively small, flat-topped inflorescence. Leaves are opposite, 3-7 cm long and 5-10 mm wide, few-toothed. A helpful distinguishing character of this narrow-leaved species is the elongate, acuminate, head bracts (vs. shorter and acute in other similar species). Very slender-leaved populations from depression meadows and clay-based bays prove to be E. paludicola.
Taxonomic CommentsCurrent concepts exclude what was formerly named E. leucolepis var. novae-angliae.

Other Common Name(s)Savanna Eupatorium, Savanna Thoroughwort, Justiceweed. This last name is often used, but it is so idiosyncratic that it imparts no taxonomy.
