Growth rings, colour, grain, etc. Growth ring boundaries indistinct or absent. Heartwood basically brown to red; without streaks. Sapwood distinct from heartwood colour. Odour distinct (aromatic). Wood of medium weight (0,52–0,55–0,65 g/cm3). Interlocked grain present.

Hardwood vs softwood. Vessels (pores) present (= hardwood).

Vessels (pores). Wood diffuse-porous. Vessels (pores) in multiples; commonly in short (2–3 vessels) radial rows. Vessels medium to large (85–140–215 µm); few (7–10–15). Tyloses absent. Other deposits in heartwood vessels (pores) present (dark reddish brown), or absent (in case sapwood is mistaken for heartwood). As with some other Meliaceae timbers (for example cedro, true mahogany, sapele), the wood of Guarea occasionally exudes sticky orange or amber colored gums.

Axial parenchyma. Axial parenchyma present; banded and not banded. Parenchyma bands exclusively marginal (or seemingly marginal); narrow. Other macroscopically visible types of axial parenchyma: aliform and confluent (occasionally also unilateral, i.e., forming semicircular caps only on one side of the vessel). Aliform parenchyma of the lozenge type.

Rays. Rays narrow. Large rays commonly less than 1 mm high.

Storied structure. Storied structure absent.
