Family: Myrtaceae

High Risk Traits:

• Thrives in tropical climates
  
• Host of Austropuccinia psidii, but this fungal pathogen already has a broad host range in the Hawaiian Islands
  
• Tolerates many soil types
  
• Reproduces by seeds
  
• Reaches maturity in 2-3 years
  
• Seeds dispersed by wind, probably water (common in riparian areas) and intentionally by people
  
• Tolerates pruning and fire
  
• Gaps in biological and ecological information may reduce accuracy of risk prediction

Low Risk Traits:

• No reports of invasiveness or naturalization, but no evidence of widespread introduction outside native range
  
• Unarmed (no spines, thorns, or burrs)
  
• Non-toxic
  
• Ornamental
  
• Not reported to spread vegetatively
