Quercus suber L.

Cork oak

About plant names...

Cork oak is a native of southwest Europe and northwest Africa. It is not native to North America. It is the principle source of cork for wine bottle stoppers. Remarkably, removal of the cork does not harm the tree.

Identification: Trees reach 66' (20 m). Leaves are 1½-2½" (4-7 cm) long, roughly oval, with a few rounded serrations. Acorns are about 1" (2.5 cm) long, with large corky caps that cover about half of the nut. See the Quercus comparison table.

From Köhler, Franz Eugen, Medizinal-Pflantzen, Gera-Untermhaus, FE Köhler, 1887.
