The tree probably belongs to the order of _Leguminosae_.

The best perfumed or diseased wood is found in the mountainous country to the east of the Gulf of Siam, including Camboja and Cochinchina.

Castenheda says that at Campar, on the eastern side of Sumatra, are "forests which yield aloes-wood, called in India Calambuco (kalambak).

The trees which produce it are large, and when they are old they are cut down and the aloes-wood taken from them, which is the heart of the tree, and the outer part is agila.

Both these woods are of great price, but especially the Calambuco, which is rubbed in the hands, yielding an agreeable fragrance; the agila does so when burned." See Crawfurd, _ut supra_, pp.
