Species profile
The heartwood is orangey yellow darkening to golden brown. Presence of whitish resin veins. It does not have clearly demarcated sapwood. The grain is straight or interlocked and the texture is coarse. Density at 12 % moisture content: 0.63 g/cm3.

The blunting effect is high and peeling and slicing is reported to be good. Resin exudation in steaming. Tendency to tearing on quartersawn. Nailing is good and gluing is correct. It dries slowly. Drying requires care in order to avoid pocket moisture. The hardness varies from soft to fairly hard.

Mersawa is poorly durable to fungi and is susceptible to dry wood borers; sapwood not or slightly demarcated (risk in all the wood).

Mersawa can be used for several applications such as:
• interior: e.g. furniture, flooring, veneer, boxes and crates, panelling, mpoulding, joinery, sliced veneer, formwork

Filling is recommended to obtain a good finish.
