Jatoba

Hymenaea Courbaril

Fabaceae

Heartwood varies from a light orangish brown to a darker reddish brown, sometimes with contrasting darker grayish brown streaks. Color tends darken upon exposure to light. Sapwood is a light grayish yellow, clearly demarcated from the heartwood.

Jatoba is rated as being very durable in regards to rot resistance, and is also resistant to termites and most other insects. (Though it has been reported to be susceptible to attack from marine borers.)
