This map is based on our research. We have checked its accuracy to Level 3 ecoregions. Although this plant occurs somewhere in each of these regions, it may only occur in a small part of some or all of them.

Habitat

Found in uplands of the Ouachita Mountains and the Scattered High Ridges and Mountains of the Arkansas Valley, on ridgetops and dry slopes.

This species belongs to the red oak group but its close relationships are not known. It was originally described as a subspecies of shumard's oak (Quercus shumardii), probably based on similarities in leaf shape, and DNA sequencing has suggested it is probably actually closest-related to this species.

Individuals have been observed that are thought to perhaps be hybrids with blackjack oak (Quercus marilandica) or black oak (Quercus velutina), but such hybridization has not been verified.
