FIG. 329. Fruiting branch with leaves of Rhus lyphina. Reproduced from Sargent's 

 "Silva of North America." 



Rhus lyphina 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 in the eastern United States and apparently sparingly distributed west of 

 the Appalachian Mountains.
