Comments: Usually a small to medium sized tree with a moderately fast growth rate, black sheoak represents a species with only moderate-to-high density wood in a genusthat’s otherwise known for hard, high density wood.
Not closely related to true oaks (Quercus genus), the etymology of the common name sheoak is ambiguous. Both oaks and sheoaks share a similar ray-flecked appearance on quartersawn surfaces.
