 trunk terete, nearly straight, 1.5 foot thick, 35 feet high or 

 higher, branched toward the top, with small buttresses at the 

 base; bark thick, roughened with minute lenticels, grayish 

 brown; wood hard, nearly odorless and tasteless, with the usual 

 brown oak vessels, becoming brownish toward the center; 

 main branches relatively short, crookedly rebranched, the rigid 

 twigs suberect; leaves ascending or descending when old, thinly 

 coriaceous, folded on the upper side, tips recurved, beneath 

 greenish white or subglaucous, the young ones yellowish green; 

 spikes erect, stout, seldom branched, 3 to 5 inches long; acorns 

 short ovoid, the recurved appendages of the cup entirely covering

 extends much further north.
