Patagonian Oak 

The trunk has greyish-brown to dark brown bark and is often forked. The leaves are alternate and somewhat curled between the veins and the serrated margin. The trees bear separate male and female flowers, both of which are small, surrounded by green bracts, and rather inconspicuous.

The old trees, which have developed the reddish heartwood characteristic of mature specimens are known as roble pellín. The tree has a good shape and its timber is valued for its durability, being used for furniture-making and in construction.
