Quercus × harbisonii,[1][2] commonly known as Harbison's oak and Harbison oak, is a rare hybrid species of oak in the family Fagaceae.
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]
