3 Rhus glabra Linnaeus, Smooth Sumac, which is very commonly a shrub forming thickets, is reported 

 by Britton and Shafer (North Am. Trees, 608, 1908) as becoming a tree 6 or 7 meters high. I have not 

 observed it as a tree. It ranges throughout eastern United States and contiguous parts of Canada and 

 westward.
