Quercus incana is the Bluejack oak. Bluejack oak is a small tree or large shrub seen in the dry, sandy scrub areas of the southeastern coast. It is called "Bluejack" because the leaves are a deep bluish grayish green on the upper surface, and densely grayish white, woolly-hairy on the lower surface, giving the tree an overall bluish cast when viewed from a distance. The leaves of Bluejack oak are tardily deciduous to evergreen, thick and leathery, with a rounded apex bearing one small bristle-tip. The acorns of Bluejack oak are very short stalked to sessile, and round.
