Norfolk-Island-pine is native a small island east of Australia, but is extensively planted for ornament. In Puerto Rico it became very popular during the 1960s and was planted widely in patios and gardens, but lost popularity perhaps because large trees are not as attractive as small ones. In Norfolk Island it reaches a height of 200 feet, with a trunk 3.5 feet in diameter. The leaves are minute and cover almost completely the branches, some leaves are short and tightly pressed together, while others are longer and erect. Male and female cones are produced on different trees, the former are elongated and the latter are oval-shaped. The generic name derives from the Chilean province of Arauco, where the first species of the group was found. The species name refers to the variable shape of the leaves.

The photographed tree is north of the supplies warehouse at the Buildings and Grounds Department, and is the only member of the species in the campus.
