Growth rings, colour, grain, etc. Growth ring boundaries distinct. Heartwood basically brown to red (light to dark reddish brown); without streaks. Sapwood distinct from heartwood colour. Odour distinct (aromatic like cedro (Cedrela odorata)). Wood light weight and soft, or of medium weight (0,35–0,55 g/m³). Interlocked grain present to absent.

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

Vessels (pores). Wood ring-porous, or semi-ring-porous (depending on growth conditions the wood is either ringporous or semi-ringporous); earlywood pore ring uniseriate (occasionally with short biseriate tracks). Vessels (pores) in multiples; commonly in short (2–3 vessels) radial rows. Vessels medium, or large (50–130 µm in latewood, 300–450 µm in earlywood); few (8–15 in earlywood), or moderately numerous (20–30 in latewood). Tyloses absent. Other deposits in heartwood vessels (pores) present (dark reddish brown, sometimes pale yellow), or absent (in case sapwood is mistaken for heartwood).

Axial parenchyma. Axial parenchyma present; banded. Parenchyma bands exclusively marginal (or seemingly marginal); narrow to wide. Other macroscopically visible types of axial parenchyma: none.

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

Resin canals. Normal resin canals absent (traumatic resin canals in tangential rows can be observed occasionally).
