| Asteraceae | Eupatorium vaseyi | Vasey's Eupatorium | Moist to dry woodlands and openings, fire-maintained woodlands over mafic rocks (such as diabase). | 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. |  |
