Family: Anacardiaceae

Astronium fraxinifolium (kingwood, locustwood) is a tree native to Brazil. It is used as a timber tree in the construction of fine furniture, construction, railway posts, fence posts, musical instruments and carving. The plant is used in traditional folk medicine for inflammation diseases. Some studies have shown the extracts to have antioxidant, antimicrobial, gastroprotective and wound healing effects. This plant has not been documented as naturalized in any Hawaiian Islands to date.

High Risk Traits:

• Broad climate suitability (based on elevation and rainfall gradients)
  
• Thrives, and could spread, in regions with tropical climates
  
• Tolerates many soil types
  
• Reproduces by seeds
  
• Seeds dispersed by wind, possibly water, and intentional cultivation
  
• Resprouts from cut stumps

Low Risk Traits:

• No reports of invasiveness or naturalization, but no evidence of widespread introduction outside native range
  
• Unarmed (no spines, thorns, or burrs)
  
• Heliophytic, and classified as shade intolerant. Dense shade may limit ability to spread
  
• Dioecious. Individual trees would presumably not be able to set seed
  
• Not reported to spread vegetatively
  
• Seeds lose viability rapidly, and should not form a persistent seed bank
