Eupatorium anomalum Nash. Anomalous Eupatorium. Phen: Aug-Oct. Hab: Moist savannas, coastal plain pondshores, moist interdune swales. Dist: NC (?) south to ne. FL, west to s. AL.

Origin/Endemic status: Endemic

Taxonomy Comments: E. anomalum is believed to be a triploid and tetraploid, apomictic derivative of the hybrid E. mohrii × rotundifolium. E. SC south to c. peninsular FL and west to s. AL. Inasmuch as it is now a separate lineage (as evidenced by a distinct distribution, more-or-less recognizable morphology, and phenologic separation), treatment as a separate taxon seems warranted.
