Queensland kauri


Queensland kauri is native to Australia and Papua New Guinea. It was introduced to Puerto Rico in the 1940s. In its native distribution it reaches a height of 165 feet, with a trunk 6 feet in diameter. The leaves are up to 6 inches long and appear to have no veins. Male and female cones are produced on the same tree, the former are dark brown, cylindrical, up to 4 inches long; the latter are green, rounded or egg-shaped, up to 5 inches wide. The generic name derives from the Greek word for a ball of thread, in reference to the shape of the female cone. The species name refers to the size of the mature tree.

The photographed tree is at the southern end of the Stefani Building. There are other trees in the Piñero Building patio, near the gate connecting to the Federal Agricultural Experiment Station, and across from the Physics Building.
