Eupatorium mohrii E.L. Greene. Common name: Mohr's Eupatorium. Phenology: Aug-Oct. Habitat: Moist pine savanna, other wet habitats. Distribution: Se. VA south to s. FL and west to TX.
Origin/Endemic status: Endemic
Taxonomy Comments: Like E. anomalum, E. mohrii is believed to be a triploid and tetraploid, apomictic derivative of the hybrid E. recurvans × rotundifolium; it is more widespread than E. recurvans sensu stricto. 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.
