152 THE SHRUBS OF NORTH CAROLINA. 



6. Poison Oak. (R. Toxicodendron, Linn.) — A 

 small shrub, 1 to 2 feet high, well known by this name 

 from the coast to the lower part of the Upper District. 

 It is less poisonous than No. 5, but is too mischievous

 found, nor any other poisonous plant which is not 

 common elsewhere. Besides, it is well known that 

 cattle do not take the disease if kept from those 

 grounds till the dew has evaporated. Its cause is yet 

 a mystery, but I am satisfied it is telluric.

 large to come under the class of Berries. They are 

 well known by their names.
