TAXONOMY : 
The currently accepted scientific name for eastern poison-oak is
Toxicodendron toxicarium (Salisb.) Gillis (Anacardiaceae) [8,9].  This
taxon is often confused in the literature with eastern poison-ivy (T.
radicans), with which it has shared the synonym Rhus toxicodendron.  A
source of confusion over identification arises from sexual dimorphism in
eastern poison-oak; male clones produce leaflets with deeper, more
pronounced lobes than do female clones [8].  This report follows the
nomenclature of Gillis [8], who appears to have resolved much of the
confusion.

The possibility of hybridization between eastern poison-oak and other
Toxicodendron species is limited due to differences in habitat.  Eastern
poison-oak forms occasional hybrids with eastern poison-ivy (T.
radicans) where their ranges overlap [8].
