The tropical tree Doussié reaches, depending on the species, a height of 15 to 40 m, with a diameter of 80 to 150 cm, sometimes more. The bole is straight and cylindrical, with slight buttresses, and covered with a greyish brown bark with lenticels.

The wood cut from red Doussié has the characteristic of having pores filled with a yellow powder, whereas those of white Doussié are filled with a white powder, hence their respective names.
