Fagaceae (Beech Family)
Gray oaks are large shrubs or small trees reaching a maximum height of 30 ft.
Deciduous, leathery,
oval leaves are dull, blue-green, sometimes turning crimson in fall. Low clump-forming
shrub or small
tree, sometimes medium-sized, with grayish foliage.
Of greatest size in moist canyons, Gray Oak is most common as a
shrub in New Mexico. It is easily seen in the Chisos Mountains in Big Bend National Park. It is closely related to Arizona White Oak, a larger
tree with larger leaves and sunken veins. Common and scientific names describe the color of the foliage.
