Code according to DIN EN 13556: none.
CITES(EU) status of protection. Listed in Annex II(B).
Geographic distribution. Burma, Thailand, Laos, Vietnam, Cambodia.
Growth rings, colour, grain, etc. Growth ring boundaries indistinct or absent. Growth increments sometimes distinct but not conspicuous, delimited by a reduction in pore size and number in the latewood. Heartwood basically brown, red, yellow (shades of lemon-pink or red-scarlet to reddish brown); with streaks. Sapwood distinct from heartwood colour. Odour distinct (faintly pleasant), or indistinct or absent. Wood heavy and hard (0.90–0.94–0.98 g/cm3). Interlocked grain occasionally present, or absent.
Hardwood vs softwood. Vessels (pores) present (= hardwood).
Vessels (pores). Wood diffuse-porous. Vessels (pores) in multiples; commonly in short (2–3 vessels) radial rows and in radial rows of 4 or more (few). Vessels rather unevenly distributed over the cross section. Vessels medium to large ((80-)165–230(-280) µm); very few ((1-)2–4(-6)). Tyloses absent. Other deposits in heartwood vessels (pores) present (reddish brown).
Axial parenchyma. Axial parenchyma present; banded and not banded. Parenchyma bands not (only) marginal; narrow; but much wider than rays. Other macroscopically visible types of axial parenchyma: vasicentric, aliform winged, confluent.
Rays. Rays narrow. Large rays commonly less than 1 mm high.
Storied structure. Storied structure present. Tiers regular (horizontal or slightly inclined); 5 per axial millimetre.
Physical and chemical tests. Heartwood not fluorescent. Water extract not fluorescent; colour shade of water extract colourless to brown. Heartwood extractives leaching out when in contact with water (yellowish brown). Ethanol extract fluorescent (yellowish green or bluish purple, depending on origin of sample); colour shade of ethanol extract colourless to brown, or yellow. Froth test positive. Splinter burns to full ash; colour of ash white to grey.
Additional information. • Transverse section + wood surface. Tangential surface, natural size. Transverse section ca. 10x.
