Quercus boyntonii is a rare and poorly known species. It is a shrub or small tree, sometimes reach a height of 6 meters (20 feet) but usually smaller. Leaves are dark green, hairless and shiny on the upper surface, covered with many gray hairs on the underside.[1][6] The oak grows along glade margins on sandstone outcrops in the pine-oak-hickory woodland.[5] The tree is threatened by fire suppression, land use changes, invasive competition (including Pyrus calleryana, Nandina, and privet), and introgression with other oaks.[5]
