Nuttall makes this the var. /3 of Q. falcata (Spanish Oak). The 

 younger Michaux does not notice it. The elder says it forms a tree from 

 20 to 40 feet high, is of rapid growth, and extremely well suited for 

 enclosing lands, which Pursh copies and adds, in pine-barrens, near the 

 sea coast, New Jersey to Georgia.

From 20 to 30 feet high, trunk small and scrubby, principally used for 

 fuel, for which purpose, according to Michaux, it is held next in estimation 

 to the Hickory ; seldom more than 2^ feet in diameter. Said to be 

 greatly used and very durable. Abundant in dry barren soil, from 

 Burlington to South Amboy, New Jersey. 



Pursh places it in barren sandy or gravelly woods. New Jersey to 

 Florida, and says it bears abundantly a fine mast for hogs.
