Similar timbers. Caution: in Brazil the local name of "arruda" is also used for two species of the genus Swartzia (S. euxylophora, S. fasciata).
Geographic distribution. Tropical South America. Northeastern Brazil.
Growth rings, colour, grain, etc. Growth ring boundaries mostly distinct. Heartwood basically red, yellow; with streaks. Sapwood distinct from heartwood colour. Odour distinct (aromatic, somewhat sweetish when freshly cut). Wood heavy and hard (0.95–1.02 g/cm3). Interlocked grain occasionally present, or absent.
Hardwood vs softwood. Vessels (pores) present (= hardwood).
Vessels (pores). Wood ring-porous to semi-ring-porous; earlywood pore ring uniseriate (frequently discontinuous). 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 small (latewood: 40–70–100 µm), or medium to large (earlywood: 105–170–240 µm); few to moderately numerous (10–15–18–33). Tyloses absent. Other deposits in heartwood vessels (pores) present.
Axial parenchyma. Axial parenchyma present; banded and not banded. Parenchyma bands not (only) marginal; narrow. Other macroscopically visible types of axial parenchyma: vasicentric and aliform winged.
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 not fluorescent. Water extract fluorescent (pale greenish blue); colour shade of water extract colourless to brown. Heartwood extractives not leachable by water. Ethanol extract fluorescent (deep lilac (magenta)); colour shade of ethanol extract red (dark pink). Froth test negative. Splinter burns to partial ash; colour of ash a mixture of grey, pink and brown.
Additional information. • Transverse section + wood surface. Tangential surface, natural size. Transverse section ca. 10x.
