Licania macrophylla is a tree growing up to 30 metres tall. The bole is buttressed and also has stilt roots[
]. It can be 40 - 60cm in diameter and unbranched for up to 18 metres[
The tree is harvested from the wild as a local source of wood and medicines. It is also harvested commercially for its timber, which is exported.

The seed oil contains licanic acid[
The heartwood is generally a yellowish brown to brown or dark brown, sometimes with a reddish tinge; it is clearly demarcated from the tan-coloured sapwood. The grain is straight; texture close and fine; without characteristic odour or taste; growth layers are not evident. The wood is very dense, hard, very heavy, strong, not very durable in the soil but very resistant to marine borers. Most species contain an abundance of silica[
]. The wood is difficult to work owing to the high silica content and hardness. The combination of these factors causes a rapid dulling of cutting edges. When sharp cutting edges are maintained, the wood can be machined to a smooth surface in planing, boring, sawing, and other operations[
]. The high marine borer resistance of the wood indicates that the highest use for these timbers is for piling and marine construction in waters infested with marine borers. The difficulty in working these timbers except with an axe or adze, as well as their high density and only moderate resistance to decay, suggests that their most suitable secondary use would be in heavy construction above ground[
The wood is used for fuel and also for making charcoal[
