The genus Quercus contains about 500 known species, plus about 180 hybrids between them. [1] The genus, as is the case with many large genera , is divided into subgenera and sections . Traditionally, the genus Quercus was divided into the two subgenera Cyclobalanopsis , the ring-cupped oaks, and Quercus , which included all the other sections.
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.
