 "Silva of North America." 



Rhus typhina is commonly known as the " staghorn sumac" in allusion to the soft 

 brown pubescence covering the twigs and branches. It is also known as the " vinegar tree" 

 and " Virginia sumac." It may attain the height of a tree, and is usually found growing in 

 uplands in good soil, ocasionally being found like Rhus glabra on barren gravelly banks. It 

 is very abundant m the eastern United States and apparently sparingly distributed west of 

 the Appalachian Mountains.
