CITESwoodID: descriptions, illustrations, identification and information retrieval
Nomenclature. Family: FABACEAE-FABOIDEAE. Other trade relevant species: Dalbergia greveana, D. perrieri, D. purpurascens, D. mollis, D. trichocarpa
. Code according to DIN EN 13556: none. Internal code: MPA II.
CITES(EU) status of protection. Listed in Annex II(B). Similar woods: other species of the genus Dalbergia .
Geographic distribution. Madagascar & other islands. Predominatly western Madagascar.
Growth rings, colour, grain, etc. Growth ring boundaries distinct (demarcated by uniseriate, often discontinuous earlywood pore ring). Heartwood basically brown, red, yellow, purple (variable according to species); with streaks, or without streaks. Sapwood distinct from heartwood colour. Odour distinct, or indistinct or absent. Wood heavy and hard (0.85–1.05 g/cm3). Interlocked grain present.
Hardwood vs softwood. Vessels (pores) present (= hardwood).
Vessels (pores). Wood semi-ring-porous; earlywood pore ring uniseriate. Vessels (pores) arranged in no specific pattern; in multiples; commonly in short (2–3 vessels) radial rows. Vessels small (latewood), or large (earlywood); few. Tyloses absent. Other deposits in heartwood vessels (pores) present, or absent (in case sapwood is mistaken for heartwood).
Axial parenchyma. Axial parenchyma present; banded. Parenchyma bands not (only) marginal (only close to growthring limits); narrow; forming a reticulate pattern with rays, or much wider than rays. Other macroscopically visible types of axial parenchyma: diffuse-in-aggregates (short lines in latewood).
Rays. Rays narrow. Large rays commonly less than 1 mm high.
Storied structure. Storied structure present. Tiers regular (horizontal or slightly inclined), or irregular; 5–6 per axial millimetre.
Physical and chemical tests. Heartwood fluorescent (Dalbergia greveana: weakly yellow), or not fluorescent. Water extract not fluorescent (D. greveana); colourless to brown. Ethanol extract not fluorescent (D. greveana); colourless to brown, or red. Froth test positive (D. greveana). Splinter burns to full ash (Dalbergia greveana); colour of ash white to grey (Dalbergia greveana).
