The stiff, holly-like leaves are convex, dark green and bear sharp, jagged edges. Leaf length is one to three inches. Leaf tips terminate in stiff points. The bark will furrow and darken with age. Spring blossoms are modest and brown.
Acorns are conical, glossy, and red-brown.
Appearing in autumn, these acorns are three-quarters of an inch to an inch and a half long. In Dublin, oaks can typically be found along Martin Canyon Creek and other creek areas.
