Wood of the species Dipteryxodorata is usually called Cumaru among woodworkers, but is sometimes referred to as “Brazilian Teak,” especially when used for hardwood flooring. [Note that Brazilian Teak is not related to the wood most commonly called Teak, Tectonagrandis.] Cumaru also can be called by the name “Tonka Bean.” This tree is often cultivated for the vanilla-cinnamon scented seed (tonka bean) that has a chemical compound called coumarin. Cumaru lumber is exceptionally stiff, hard, and strong, which makes it suitable for a variety of applications. It is sometimes substituted for the scarce wood Lignum Vitae. Cumaru heartwood fluoresces under blacklight, allowing it to be distinguished from Ipe.
