Sand shinnery oak, Havard shinoak

Quercus havardii Rydb.

Fagaceae (Beech family)


Sand shinnery oak is a low, shrubby tree of the Beech family. It rarely reaches more than 3 feet tall. Because of their aggressive underground rhizomes, these trees can form dense thickets over large areas and in deep sands.

The leaves are deciduous and located alternately along the stems. The leaves have a leathery, rough texture and pointed lobes.

Sand shinnery oaks produce typical oak-type acorn fruit. Produced annually in the spring, the acorns of this tree are rather large, ranging from 1/2 to 1 inch long and 1/2 to 5/8 inch wide.

The tree may hybridize with other shin oak and live oak species.

The young stems and acorns are poisonous to livestock and the plant provides fair forage for wildlife.


Sand shinnery oak grows in deep, sandy soils in the western part of Texas, including the lower Panhandle, Permian Basin and Trans-Pecos regions.
