Wood Technical Fact Sheet
Other Common Names: Capote, Siete cueros (Colombia), Cascaron (Venezuela), Chiche (Ecuador), Tuseque, Morado (Bolivia), Jacaranda, Jacaranda pardo (Brazil).
Distribution: The species of this group are widely distributed throughout tropical America but are most abundant in Brazil, with commercial sources in the southeast.
The Tree: Medium-sized, rarely large trees.
General Characteristics: Heartwood brown to dark violet brown, often streaked, rather waxy; sapwood whitish, grayish, or yellowish. Luster medium to high; texture fine coarse; grain straight to irregular; without distinctive taste but sometimes walnut scented. Wood dust may cause dermatitis.
Weight: Basic specific gravity (ovendry weight/green volume) 0.65 to 0.75; air- dry density 49 to 57 pcf.
Mechanical Properties: (2-cm standard)
Moisture content Bending strength Modulus of elasticity Maximum crushing strength

Janka side hardness for green material 1,450 to 1,780 lb. Amsler toughness 282 to 346 in.-lb at 15% moisture content (2-cm specimen).
Drying and Shrinkage: No information on drying characteristics available. Shrinkage green to ovendry: radial 2.6%; tangential 6.6%; volumetric 10.0%. These values are exceptionally low for a wood of this high density.
Working Properties: Reported to be fair to excellent.
Durability: Heartwood highly resistant to attack by decay fungi.
Preservation: No information available.
Uses: Fine furniture, decorative veneers, turnery, specialty items, and cabinet work. Generally useful for the same purposes as Brazilian rosewood (Dalbergia nigra).
