In mixed plantings with other species in Ekouk (Gabon), the survival rate was 30 - 70% after 3 years, without much mortality afterwards. When 10 years old, the trees had an average bole diameter of 8 - 9cm. Although they were in good health, all trees had a sinuous bole. In Lopé (Gabon) the annual increase in bole diameter was 4.5mm in dense forest and 6.8mm in more open Marantaceae forest[

The heartwood is pinkish white to grey-cream; it is not distinctly demarcated from the 5 - 9cm wide band of sapwood. The grain may be interlocked, crossed or straight; the texture is rather coarse; the wood contains 0.1 - 0.5% silica.
The wood is medium-weight; it is not durable and is liable to attack by fungi, termites and other insects, but is resistant to marine borers[

]. The high silica content, and the presence of interlocked grain, may cause problems during processing and make special equipment necessary. The wood saws easily, but with serious blunting effect, necessitating the use of stellite teeth and tungsten carbide tools - the working angle should be reduced as much as possible. Quarter sawn pieces have a ribbon-like aspect and are sometimes marbled; flat-sawn pieces have better surfaces after processing. The peeling properties are good. Although the wood can be peeled without prior steaming, steaming is recommended to improve the quality of the sheets obtained; it is not recommended or useful for slicing. Gluing properties are good, but problems may arise with glues based on phenol-formol. Nailing, screwing and finishing properties are good. The wood is not recommended for temporarily or permanently humid conditions. The wood is especially used for plywood (for boxes, packaging or furniture) and no longer used much in massive form, although it can be sawn into planks for interior joinery, furniture, carpentry, moulding, parquetry, interior stairs, panelling, vehicle bodies, boat hulls, boxes and poles. Locally, the wood is used for making canoes. It is suitable for papermaking[
