Quercus Suber, Cork Oak. 
QUERCUS SUBER 
The subject of our illustration is a very fine specimen 
of Quercus Suber, Cork Oak. The bark of this tree 
furnishes the cork of commerce. 
This particular tree is growing on private grounds at 
Rockingham. North Carolina, and originally came from 
Spain. It is a magnificent specimen and is evidently 
quite at home. 
Like the Live Oak, so common in the Southern States, 
it is evergreen, but is quite distinct; perhaps the most 
striking feature is the thick, deeply furrowed spongy 
bark, which gives the trunk a very massive and attrac¬ 
tive appearance. 
According to Bailey’s Cyclopedia it is much cultivated 
in California, where it thrives well. 
A very similar species is Quercus occidentalis, which 
differs only in having its fruit ripen the second year and 
being much more hardy; its bark is not distinguished 
commercially from the true Cork Oak.
