The heartwood is yellowish white, though darkening upon exposure to light; it is not distinctly demarcated from the sapwood. The grain is straight, occasionally wavy; the texture moderately coarse; lustre is low; there is no distinctive odour or taste. The wood is soft, light in weight, interspersed with latex vessels and inclined to be gummy. It is perishable in the ground, and is susceptible to termites, borers, and to blue stain unless treated with preservative. It seasons rapidly with little or no degrade due to warping and checking; once dry it is fairly stable in service. It works well with ordinary tools, though the presence of latex can clog sawblades; it does not take nails or screws well; but glues corect. It is suitable for light carpentry, furniture, veneer, boxes, mouldings, pencils, match-splints, etc. It is used locally for making wooden bowls and plates, toys, masks, canoes, etc[
