Very strong rather plain yellow to brown hardwood. I am not aware of any original bow from this wood, so I would use it only for modern bows. Now sometimes called "Pau D'arco," it has been demonstrated to have very close physical characteristics to pernambuco, including high "Lucchi" test result.  Very successful for this purpose.

Attractive, looks like Pernambuco when worked, but is usually lighter in weight and somewhat more flexible. Good for some high-tipped classical bows, and cello or gamba bows. Its strong point is that bows from this wood produce a particularly sweet tone quality.

This can be a very beautiful bow wood. It is a good weight, but tends not to be as stiff as might be ideal. Good for some early classical models. For modern use requires a higher tip and frog.

Greenheart wood has many of the qualities required for fine bows: good colour (beige to brown, not green) appropriate elasticity, good tonal qualities. Worthy of further study.
