This is one of the many ways people name the cork tree. They also call it Extremadura cork oak, casquizo cork oak, cork oak, migueleñas acorns, bell. pigeons, bell. martinencas , chaparro , cork , oak sobrero , sobreiro . . . Botanists, more serious themselves, call him quercus suber. Its bark, cork, defends it from fires and has many industrial uses. The most common and traditional, the cap of wine bottles. For my tierruca there are not many, but a little further south yes, in the Arribes, Salamanca, Extremadura and especially in our sister land, Portugal. The Quercus are my favorite trees, the oaks, the holm oaks, the cork oaks. How Stoic they are!
