Baphia Nitida or Red Sandalwood is a class of woods from trees in the genus Santalum. The woods are heavy, yellow, and fine-grained, and unlike many other aromatic kinds of wood, they retain their fragrance for decades. Sandalwood is the second most expensive wood in the world, after African Blackwood. Both the wood and the oil produce a distinctive fragrance that has a high value for centuries. Consequently, species of these slow-growing trees have suffered over-harvesting in the past century.
