Scientific name: Heritiera utilis Kosterm; H. densiflora Kosterm

Geographic origin: West Africa and Central Africa


  • Sapwood: greyish bown
  • Heartwood: varies from reddish brown to pink brown.
  • Fiber: Straight, generally slightly intertwined
  • Grain: medium size to rough

Capacity of being impregnated

  • Sapwood: Low capacity of being impregnated
  • Heartwood: No capable of being impregnated


  • Sawing process: Easy, except in those cases of oil presence that can cause allergies.
  • Drying process: Speed can vary from medium to high speed. Low to medium risks of deformation and crack formation.
  • Planing process: Difficulties arise from risk of repelling due to frequently intertwined fibers.
  • Gluing process: No difficulties.
  • Nailing and screwing process: No difficulties.
  • Finish: No difficulties, except in those cases of oil stain existance, that must be eliminated with a solvent.

They are usually small diameter twisted trunks and so it is very difficult to obtain wide and long Goods.
