Oak Hybridization At The University of Utah

This excellent image, created by Dr. Cottam and his colleagues, shows the range of leaf variation found in the offspring from a wild hybrid of Quercus turbinella x gambelii, found growing wild in Utah. Seedlings of tree were grown, and each leaf image represents a typical leaf from one of the hybrid seedlings. The leaves toward the end show very similar characteristics to the parent Q. gambelii, while the first images show leaves very similar to the Q. turbinella parent.
