A purplish hardwood obtained from species in the genus Peltogyne that are native to tropical regions of Central and South America.

Physical and Chemical Properties
- Tree grows to heights of 50 m and diameter of 1 m.
- Specific gravity = 0.8-1.0 (air dry)
- Density = 60-65 ppcf
- Heartwood is dull purplish brown when cut but with exposure to air turns a deep eggplant purple; with further aging it becomes dark brown
- Grain is usually straight and texture is medium with a good natural luster
- Wood is very resistant to decay and insect attack
