Scientific Name: Gabonos discus (Cylicodiscus gabunensis)
Common Names: Okan, Denya, Disc Bean
Family: Mimosa
Geographic Origin: This tree species is predominantly found in the tropical regions of West Africa. Nigeria and Ghana stand out as the primary producers due to their favorable climate and soil conditions.
Key Identification Features: The heartwood and sapwood of this wood species display a striking contrast in color. The heartwood is characterized by a golden-brown hue with a slight greenish tint that may turn reddish-brown over time. It features prominent dark streaks, while the sapwood is lighter, often appearing in shades of pink. The texture is somewhat porous, and the wood contains loose hole material. Its axial thin-walled tissue forms short wings and gathers in a wing-like pattern. The wood has single perforations, and its inter-tube perforation is notable. The wood rays are non-stacked, and the multi-row rays are typically 2 to 4 cells wide. The ray tissue exhibits a columnar arrangement, creating an interesting visual effect.
Physical Properties and Applications: With an air-dry density ranging from 0.96 to 1.00 g/cm³, this wood is incredibly dense and durable. It is ideal for heavy-duty applications such as constructing bridges, building heavy structures, flooring, crafting high-quality furniture, and even shipbuilding. Its strength and stability make it a preferred choice for projects requiring resilience and longevity.

After researching the properties of Gabonos discus, I found it quite fascinating how versatile this wood is despite its challenging workability due to its high density. It’s also interesting to note how certain cultural and traditional practices might influence its use in specific regions. For instance, in some African communities, this wood is highly valued for its durability and aesthetic appeal, making it a popular choice for ceremonial objects and traditional crafts. I’m curious about whether this wood could be more widely adopted in global markets, given its robust nature and potential applications. It would be great if there were more detailed studies on sustainable harvesting practices to ensure its conservation for future generations.
