Value & Sustainability
- Estimated Market Value
- $10.00 - $15.00 per board foot, depending on region and availability.
- Wood Age Estimate
- The sample appears relatively fresh or recently surfaced, evidenced by the clean edges and lack of deep oxidation or graying associated with weather exposure.
- Sustainability Status
- Listed on the IUCN Red List as Near Threatened; not currently CITES listed, though FSC certified stock is preferred.
Common Uses
Outdoor furniture, boat building, flooring, cabinetry, veneer, and general construction where durability is required.
Geographic Origin
Tropical Africa (West and East coastal regions).
Workability
Generally easy to work with, but interlocked grain can cause tear-out during planing. It may cause significant blunting of tool edges due to occasional calcium carbonate deposits within the wood.
Finish Recommendations
Takes most finishes well. Due to its large pores, a grain filler is recommended for a smooth finish. Polyurethane or outdoor-refined oils are best for exterior use.
Notable Features
Distinctive faintly sweet scent when worked; can cause skin and respiratory irritation; lacks the oily feel of Teak despite similar performance.
