06s. The bark of this tree is much sought after by our Tanners, who (not 

 being acquainted with the Q,. falcata,) erroneously call it " Spanish Oak," 

 and give it the preference over all the other Oaks that are common here, 

 for their business. The crimson leaves of this species, where it abounds, 

 impart a gorgeous and magnificent appearance to our forests, in autumn ; 

 and it is really marvellous that a tree so handsome at all seasons, should 

 be so rarely seen in the lawns and pleasure-grounds of persons of any 

 pretensions to taste.

 acute ; lobes incised-dentate with the teeth very acute ; cupule shallow,

 rather large and turgidly oblong-ovoid.
