Description edit
It is a medium-sized deciduous to semi-evergreen tree.[3]
Taxonomy edit
The Harbison oak is a naturally occurring hybrid of the post oak and live oak. It was originally described by Sargent as Quercus stellata var. margaretta × Quercus virginiana var. geminata.[1] Some taxonomists regard Quercus margarettae and Quercus geminata as separate species. EJ Palmer noted that some Quercus × harbisonii were of the typical subspecies.[2] Thus, Quercus × harbisonii is easily said as a hybrid of the post oak and live oak in the broad sense.
Distribution edit
The tree is found in the southeastern United States. It is known from the states of Florida, North Carolina, South Carolina, Georgia, Texas and Oklahoma.[3][4]
