CITESwoodID: descriptions, illustrations, identification and information retrieval
Nomenclature. Family: FABACEAE-FABOIDEAE. Other trade relevant species: of the same genus: Pericopsis angolensis, P. laxiflora, P. mooniana. Other taxa of the same family: Acosmium spp. Synonym(s): Afrormosia elata. Further trade and local names: assamela (CI, FR); obang (CM); bohala, wahala (CF). Code according to DIN EN 13556: PKEL. Internal code: AFR.
CITES(EU) status of protection. Listed in Annex II(B). Similar woods: Pericopsis angolensis, P. laxiflora, P. mooniana (not protected under CITES).
Geographic distribution. Tropical Africa. Tropical regions of Central and West Africa (Ivory Coast, Ghana, Cameroon, RCA, Zaïre).
Growth rings, colour, grain, etc. Growth ring boundaries distinct, or indistinct or absent (from time to time demarcated by darker latewood bands with fewer pores). Heartwood basically brown to yellow to green; rarely with streaks. Sapwood distinct from heartwood colour. Odour indistinct or absent. Wood of medium weight (0,6–0,7 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 medium (80–110–150 µm); few (9–16–23). Tyloses absent. Other deposits in heartwood vessels (pores) present (mostly dark coloured, occasionally white = lime), or absent (in case sapwood is mistaken for heartwood).
Axial parenchyma. Axial parenchyma present; not banded. Other macroscopically visible types of axial parenchyma: vasicentric, aliform, and confluent (occasionally also unilateral, i.e., forming semicircular hoods or caps only on one side of the vessel). Aliform parenchyma of the lozenge type.
Rays. Rays narrow. Large rays commonly less than 1 mm high.
Storied structure. Storied structure present. Tiers regular (horizontal or slightly inclined); 2–3 per axial millimetre.
Physical and chemical tests. Water extract not fluorescent; colourless to brown. Heartwood extractives leaching out when in contact with water (brownish). Ethanol extract not fluorescent; colourless to brown to yellow. Splinter burns to partial ash; colour of ash white to grey to yellow-brown.
Additional information. United Kingdom, Ghana and Denmark (1991). CITES proposal. Inclusion of Pericopsis elata in Appendix II. • afr.jpg. Radial surface, natural size. Transverse section ca. 10x. Pericopsis elata (Afrormosia, Kokrodua). • afr-acs.jpg. Acosmium sp. (Lapachillo). • afr-lap.jpg. The woods of Tabebuia species (Lapacho group) differ considerably from Pericopsis elata on account of the olive-brown heartwood color, yellow contents in vessels/pores and the high density (around 1,00 g/cm3).
