Teak is native to Southeast Asia. It was introduced to Puerto Rico early in the 1940s. In its native distribution it reaches a height of 150 feet, with a trunk 6 or more feet in diameter supported by prop roots.  The leaves are rough and up to 2 feet long. Flowers are about three-eighths of an inch wide and are grouped in large terminal inflorescences. Fruits resemble bladders up to 1 inch wide, inside of which there is a hard structure containing up to four seeds. It flowers from spring to autumn and has fruits during most of the year. The golden-brown wood, very  stable and resistant to rotting, is used extensively for patio furniture and yacht decks. The generic name means builder, in reference to the use of the wood. The species name refers to the size of the mature tree.

The photographed tree is one of two specimens located near the Barcelona street entrance to the campus. There are other trees south of the General Library, north of the new Agricultural Sciences greenhouses, and north of Building C.
