Quercus rotundifolia

Quercus rotundifolia, the holm oak or ballota oak, is an evergreen oak native to the western Mediterranean region, with the majority of the population in the Iberian Peninsula and minor populations in Northwest Africa. The species was first described by Jean-Baptiste Lamarck in 1785. It is the typical species of the Iberian dehesa or montado, where its sweet-astringent acorns are a source of food for livestock, particularly the Iberian pig. Its acorns have also been used for human nourishment since the Neolithic era (7,000 BC). It is placed in section Ilex. Some authors described it as a subspecies of Quercus ilex.
