Oak Hybrid

Quercus X

Hybrid

We are learning that oaks hybridize much more than previously thought. All these leaves came from a single tree in Tiburon. Note the tufts of hairs at the vein unions on the underside of the leaf, typical of coast live oak, but smooth leaf margins? Not so much. This is likely a hybrid of coast live and either shreve or interior live oak.
