Quercus fusiformis, commonly known as escarpment live oak, plateau live oak, or plateau oak, is an evergreen or nearly evergreen tree. Escarpment live oak is typically found on dry sites.
Quercus fusiformis is an evergreen tree in the white oak section of the genus Quercus. It is distinguished from Quercus virginiana (southern live oak) most easily by the acorns, which are slightly larger and with a more pointed apex. It is also a smaller tree, not exceeding 1 meter (40 inches) in trunk diameter (compared to 2.5 m (75 inches) in diameter in southern live oak), with more erect branching and a less wide crown. Like Q. virginiana, its magnificent, stately form and unparalleled longevity has endeared it to generations of residents where it is native.
