Live oak was widely used in early American butt shipbuilding.Because of the trees' short height and low-hanging branches, lumber from live oaks was used in curved parts of the frame, such as knee braces (single-piece, L-shaped braces that spring inward from the side and support the deck), in which the grain runs perpendicular to structural stress, making for exceptional strength.
The Baranoff Oak in Safety Harbor, Florida is reportedly the oldest live oak in Pinellas County, Florida and is estimated to be between 300 and 500 years old. McDonogh Oak in City Park, New Orleans , LA is around 800 years old and several beams have been erected to support the trees’ limbs.
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 metre (40 inches) in trunk diameter – compared to 2.5 m (75 in) in diameter in southern live oak – with more erect branching and a less wide crown. [5]

Small – dwarf live oak – # southeastern North America; Quercus oleoides Schltdl. & Cham. – # from Costa Rica into Mexico
The "Big Tree" is a species of oak called Quercus virginiana. These oak trees can be found from Texas to Florida with their range extending northward to Virginia. The common name for the Quercus virginiana is the live oak but includes the names southern live oak and the Texas live oak too. Live oak growth rate and size vary by location.
Quercus agrifolia, the California live oak, [3] or coast live oak, is an evergreen [4] live oak native to the California Floristic Province.Live oaks are so-called because they keep living leaves on the tree all year, adding young leaves and shedding dead leaves simultaneously rather than dropping dead leaves en masse in the autumn like a true deciduous tree.

While hybridization occurs between Q. geminata and Q. virginiana, the two species are genetically and morphologically distinct. [10] The Cuban oak, Q. sagrana, has been purported to be a hybrid [11] [12] between the sand live oak and Q. oleoides, but recent evidence suggests that the Cuban oak is a separate species without hybrid origin.

Quercus chrysolepis, commonly termed canyon live oak, canyon oak, golden cup oak or maul oak, is a North American species of evergreen oak.Its leaves are a glossy dark green on the upper surface with prominent spines; a further identification arises from the leaves of canyon live oak being geometrically flat.
