Aquilaria crassna

Aquilaria crassna is a species of plant in the Thymelaeaceae family. It is found in throughout Southeast Asia and in New Guinea.


Aquilaria crassna is one source[2] of agarwood, a resinous heartwood, used for perfume and incense.[3] The resin is produced by the tree in response to infection by a parasitic ascomycetous mould, Phaeoacremonium parasitica,[4] a dematiaceous (dark-walled) fungus.
