Eupatorium leucolepis (A.P. de Candolle) Torrey & A. Gray. Common name: Savanna Eupatorium, Justiceweed. Phenology: Aug-Oct. Habitat: Pine savannas, seepage bogs, depression ponds. Distribution: Primarily of the Southeastern Coastal Plain, ranging from NY south to n. peninsular FL, Panhandle FL, and west to LA; disjunct in Coffee County, TN (Chester, Wofford, & Kral 1997)
ID notes: This species is often confused with members of the E. recurvans-mohrii-anomalum complex. The following differences are useful: E. leucolepis has phyllaries acuminate to attenuate (vs. acute to obtuse), leaves of the uppermost nodes below the inflorescence opposite, or rarely the uppermost 1-2 nodes subopposite (vs. leaves of the uppermost 2-15 nodes below the inflorescence alternate), and leaves generally longitudinally folded (vs. generally planar).
Origin/Endemic status: Endemic
Taxonomy Comments: The plants formerly called E. leucolepis var. novae-angliae Fernald and endemic to freshwater pondshores in MA and RI apparently represent a distinct allopolyploid species, E. novae-angliae (Fernald) V.I. Sullivan ex A. Haines & Sorrie, and should not be treated as a variety of E. leucolepis.
