Nomenclature. Family: FABACEAE-FABOIDEAE. Further trade and local names: palissandre de Vietnam (FR); cam lai, cay trac (VN); ching chan (TH); neang nuon (KH). Code according to DIN EN 13556: none.
CITES(EU) status of protection. Listed in Annex II(B).
Similar timbers. All Dalbergia species with a golden brown to dark brown heartwood and a diffuse pore distribution.
Geographic distribution. Thailand, Laos, Vietnam, Cambodia.
Growth rings, colour, grain, etc. Growth ring boundaries indistinct or absent. Vessel very variable in size, but exhibiting no clear zonation indicative of growth rings. Heartwood basically brown (medium to dark brown); frequently with streaks. Sapwood distinct from heartwood colour. Odour distinct (faintly fragrant when freshly cut), or indistinct or absent. Wood heavy and hard (0.90–1.10 g/cm3). Interlocked grain occasionally present, or absent.
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 and in radial rows of 4 or more (few). Vessels rather unevenly distributed over the cross section. Vessels medium to large (120–190–230(-270) µm); very few to few (3–5–8). Tyloses absent. Other deposits in heartwood vessels (pores) present (honey coloured).
Axial parenchyma. Axial parenchyma present; banded and not banded. Parenchyma bands not (only) marginal; narrow to wide; much wider than rays. Other macroscopically visible types of axial parenchyma: aliform lozenge type and confluent.
Rays. Rays narrow. Large rays commonly less than 1 mm high.
Storied structure. Storied structure present. Tiers regular (horizontal or slightly inclined); 5–6 per axial millimetre.
Physical and chemical tests. Heartwood not fluorescent. Water extract fluorescent (bluish green (turquoise)); colour shade of water extract colourless to brown. Ethanol extract fluorescent (light lilac); colour shade of ethanol extract colourless to brown (deep brown). Froth test positive. Splinter burns to full ash; colour of ash white to grey.
Additional information. • Transverse section + wood surface. Transverse section ca. 10x. Wood surface, natural size.
