Start with the overall color balance. This wood reads as cream to warm tan, and crucially the darker reddish-brown color is carried in the vessels (pores) rather than soaking the whole background. If you are looking at a board that is uniformly red-brown or chocolate throughout, it is probably not this wood; here the pale ground with darker pore lines is the signature.
Next, use the rays. On the radial (quartered) face the rays show up as fine, closely and evenly spaced flecks or short bands running across the grain, producing a subtle ray fleck rather than the bold, silvery quarter-figure of oak. Prominent, regular rays like these are a genuine diagnostic feature - inspect the radial surface in raking light and, ideally, a cleanly cut end grain under a hand lens: look at how the pores are arranged (scattered/diffuse vs. in rings or clusters) and how wide and frequent the rays are. Those end-grain traits are what an anatomist would use to pin the species, and they are the most trustworthy cues you have.
Judge weight and hardness by hand. A medium-to-hard hardwood in the estimated ~1,000-1,700 lbf range will feel solid and resist a thumbnail dent; if the board feels light and soft, or unusually dense and heavy, reconsider the identification. Smell is not a reliable cue here - no distinctive odor is documented for this unconfirmed wood, so a strongly aromatic or peppery board points elsewhere.
Be careful with look-alikes. Many pale, warm-toned West African hardwoods can resemble this sample. African mahogany (Khaya) and sapele/utile are pinker-to-redder through the whole board and lack this prominent, even ray fleck. Iroko and afara/limba tend toward a more yellow or greyish tan and a coarser, blander figure. Genuine oak has far larger, longer rays and visible growth-ring pore bands. Because several local timbers can share this cream-and-reddish-pore appearance, the honest conclusion is that end-grain anatomy - not color alone - is what separates them, and a confident species ID needs a magnified end-grain examination or a lab, not just the face grain.
Frequently asked questions
What single feature is most useful for identifying this wood?
The combination of a pale cream-to-tan background with reddish-brown color concentrated in the pores, plus fine, evenly spaced rays visible on the radial face. Confirm it on a clean end grain under a lens rather than trusting the face color alone.
How do I tell it from African mahogany or sapele?
Those woods are pinker-to-redder through the whole board and do not show this prominent, even ray fleck. Here the background stays pale cream/tan and the red color sits mainly in the vessels.
Can I identify it by smell?
Not reliably. No distinctive odor is documented for this unconfirmed timber, so a strongly scented board is probably a different species. Rely on the rays, pore arrangement, color balance, and weight instead.
How can I be sure of the exact species?
You generally cannot from face grain alone. Cut and examine a clean end grain under magnification, or send a sample to an accredited wood-anatomy lab. Since 'Direm' here is only a tentative attribution, confirmation matters if the identity affects compliance or performance.
