How to Identify Afzelia
Recognize Afzelia (Doussie) by its reddish-brown heartwood, interlocked grain, pale straw sapwood, heavy weight, and yellow pore deposits.

Start with color and grain. Afzelia heartwood is a warm reddish-brown to medium brown that deepens with age, set against a clearly paler, straw-to-yellowish sapwood. The grain is interlocked, so quartersawn faces show a soft, broken ribbon or stripe figure that shifts with the light, while flatsawn faces read as a more even reddish-brown with a medium, slightly coarse texture — the appearance captured on our sample.
The most reliable diagnostic is the end grain and pores. Afzelia is diffuse-porous with large, well-spaced vessels that are easily seen without a lens, and many of them are plugged with pale yellowish or whitish mineral and resin deposits — small light flecks dotting the darker background. Those cream-colored pore fillings, together with the reddish-brown ground, are a strong tell that separates it from most look-alikes. On the end grain the parenchyma often appears as fine light bands around the pores.
Judge weight and hardness. Afzelia is distinctly heavy and hard in the hand (around 800 kg/m³, Janka ~1,810 lbf) — noticeably denser than sapele, utile, or mahogany, and it resists denting from a thumbnail. It has little characteristic odor when worked, which itself helps rule out aromatic woods.
Separating it from look-alikes is where the pore deposits earn their keep. True (Khaya) and 'sapele' family African timbers are lighter, softer, and lack the cream pore fillings. Iroko is more golden-yellow-brown, coarser, and often has calcium 'stone' deposits rather than the pale waxy plugs of Afzelia. Merbau (Intsia) is Afzelia's closest twin — similar reddish-brown color, interlocked grain, and yellow pore deposits — but merbau tends to be a slightly darker, more orange-brown, comes from Southeast Asia/Pacific, and its yellow flecks are especially prominent; provenance and trade name (Doussie/Apa vs. merbau/kwila) are often the deciding clue. Genuine mahoganies and dark tropicals like wenge differ clearly in weight, pore pattern, or color.
Frequently asked questions
What is the single best clue that a board is Afzelia?
The combination of a heavy, hard reddish-brown board with interlocked grain and pale yellowish-white deposits filling the large pores. Those cream-colored pore plugs against a red-brown ground are the standout diagnostic.
How do I tell Afzelia from merbau?
They are very close — both reddish-brown, dense, interlocked, with yellow pore deposits. Merbau (Intsia, from SE Asia/Pacific) tends to be a slightly darker orange-brown with very prominent yellow flecks, while Afzelia/Doussie is West African. Trade name and provenance usually settle it, since visual differences are subtle.
How can I distinguish Afzelia from African mahogany (Khaya)?
Weight and pores. Afzelia is markedly heavier and harder and carries pale mineral deposits in its pores; Khaya (African mahogany) is lighter, softer, more uniformly reddish, and lacks those cream pore fillings.
Does Afzelia have a distinctive smell?
Not really — it has little characteristic odor when cut, so a strongly scented board is probably something else. Rely instead on the weight, reddish-brown color, interlocked grain, and yellow pore deposits.
