-Poison oak (Toxicodendron diversilobum) and its eastern counterpart [[poison ivy]] (T. radicans) are two of the North American plants most painful to humans. Note: These species were formerly placed in the genus ''[[Rhus]]''. Poison oak and a related, look-alike shrub, ''Rhus trilobata'' belong to the ''[[sumac]]'' family (''Anacardiaceae'').
-Poison oak is widespread throughout the mountains and valleys of [[California]]. It thrives in shady canyons and riparian habitats. It commonly grows as a climbing vine with aerial (adventitious) roots that adhere to the trunks of [[oak]]s and [[platanus|sycamores]].
-Rocky Mountain poison oak (Toxicodendron rydbergii) occurs in canyons throughout the western [[United States]] and [[Canada]]. Because the two species of western poison oak look like a [[vine]] as they develop, some authors list poison oak as a subspecies of eastern poison ivy.
-Poison oak often grows like a climbing vine.
-The cautionary rhyme "leaves of three, let it be" applies to poison oak, as well as to [[Toxicodendron radicans|poison ivy (''Toxicodendron radicans'')]].
