Growth rings, colour, grain, etc. Growth ring boundaries distinct (marked by fine marginal parenchyma bands, which are usually only visible with a hand lens). Heartwood basically brown, red (fresh heartwood yellowish brown to orange brown, darkening to copper brown); without streaks. Sapwood distinct from heartwood colour (light yellowish). Wood heavy and hard (0,75–0,80–0,90 g/cm3). Interlocked grain present.
Hardwood vs softwood. Vessels (pores) present (= hardwood).
Vessels (pores). Wood diffuse-porous. Vessels (pores) arranged in no specific pattern; in multiples; commonly in short (2–3 vessels) radial rows. Vessels large (120–200–280 µm); very few (2–3(-5)). Tyloses absent. Other deposits in heartwood vessels (pores) present (with dark (reddish to blackish brown) and light (yellow to almost white) organic inclusions).
Axial parenchyma. Axial parenchyma present; banded, or not banded. Parenchyma bands exclusively marginal (or seemingly marginal); narrow. Other macroscopically visible types of axial parenchyma: aliform winged, confluent.
Rays. Rays narrow. Large rays commonly less than 1 mm high.
Storied structure. Storied structure absent.
Physical and chemical tests. Heartwood fluorescent (bright yellow). Water extract not fluorescent; colour shade of water extract colourless to brown, or yellow. Heartwood extractives leaching out when in contact with water. Ethanol extract fluorescent (yellow); colour shade of ethanol extract colourless to brown, or yellow. Froth test negative. Splinter burns to partial ash; colour of ash bright white.
