Family: Phyllanthaceae

High Risk Traits:

• Thrives in tropical climates
  
• Possibly naturalizing on Oahu, Hawaiian Islands (confirmation needed)
  
• Other Breynia species are invasive
  
• Used as a fish poison, and potentially toxic to humans if ingested
  
• A shrub to small tree that can become a climber
  
• Reproduces by seeds
  
• Seeds dispersed by birds and other frugivorous animals
  
• Possibly water dispersed
  
• Limited ecological information reduces accuracy of risk prediction

Low Risk Traits:

• No reports of invasiveness or naturalization (with the possible exception of Oahu), but no evidence of widespread introduction outside native range
  
• Unarmed (no spines, thorns or burrs)
  
• Ornamental and medicinal uses
  
• Not reported to spread vegetatively
  
• Seeds recalcitrant; lose viability after 3 months
