The tree here described belongs to the Natural Order Diptero- 
carpece (Bl. Lind.) All the trees belonging to this family are 
gigantic and of a majestic appearance, and are cniefly remarkable 
for the beautifully colored and winged fruits. All of them con- 
tain more or less of a balsamic resin. Shorea robusta produces a 
resinous substance which is used at the religious solemnities of 
the Indians. Valeria Indica yields a resin which in India is used 
as copal, and is known in Europe as amme-resin. The Javanese 
species of Dipterocarpus are all resinous, and the resin is said to 
be used as copaiva-balsam. 
The camphor-tree is one of the loftiest of the Indian Archipelago. 
In its dimensions it surpasses even the rasamala-tree (Mtingia 
excelsa) of Java. It is the giant among the trees of the East 
Indies. Its trunk rises vertically, and divides into branches only
