Eupatorium vaseyi T.C. Porter. Common name: Vasey's Eupatorium. Phenology: Jul-Oct. Habitat: Moist to dry woodlands and openings, fire-maintained woodlands over mafic rocks (such as diabase). Distribution: Various interpretations of this taxon have led to confusions and uncertainties regarding its distribution; Schilling (2011) shows records for e. TN and sc. KY and a recent discovery on Crowley's Ridge in AR (Witsell, pers. comm., 2017) represent the only confirmed distribution, but it should be sought elsewhere.
Origin/Endemic status: Endemic
Taxonomy Comments: This species is an apomictic species derived from E. petaloideum × sessilifolium (Schilling 2011). It has often been treated as a variety of E. album, but is better regarded as a species of hybrid origin.
