Scan of Rhus glabra leaf

Smooth sumac is distributed throughout the continental United States and overflows into both southern Canada and northern Mexico.

In photographs on the Minnesota Wildflowers site, you can see evidence of the ability of Rhus glabra to propagate vegetatively, allowing it to form a contiguous mass of clonal plants. The Virginia Tech Forestry Department also has a series of photographs for smooth sumac that are worth investigating.
