* Heritage tree, Penaga Laut (Calophyllum inophyllum) at Singapore Botanic Gardens
Now, it is widely cultivated in all tropical regions of the world. Because of its decorative leaves, fragrant flowers, and spreading crown, it is best known as an ornamental plant.
* This tree often grows in coastal regions, as well as nearby lowland forests. However, it has also been cultivated successfully in inland areas at moderate altitudes. It tolerates varied kinds of soil, coastal sand, clay, or even degraded soil.
* The seeds yield a thick, dark green tamanu oil for medicinal use or hair grease. The nuts are dried before cracking, after which the oil-laden kernel is removed and further dried. The first neoflavone isolated from natural sources (1951) was calophyllolide from C. inophyllum seeds.
* The sap of the tree is poisonous and is used to make poison arrows in Samoa. The mature fruit is poisonous enough to use as rat bait.
* Besides being a popular ornamental plant, its wood is hard and strong and has been used in construction or boatbuilding. more...
