Family: Fabaceae

High Risk Traits:

• Elevation range exceeds 1000 m, demonstrating environmental versatility
  
• Thrives in tropical climates
  
• Naturalized on Hawaii, possibly Maui (Hawaiian Islands) and elsewhere
  
• Aggressive, weedy liana with potential negative impacts on agriculture and the natural environment
  
• Other Derris species are invasive
  
• Toxic to animals and people
  
• Tolerates many soil types
  
• Smothers other vegetation
  
• Reproduces by seeds (rarely, if ever, in the Hawaiian Islands) and vegetatively
  
• Reaches maturity in 18 months
  
• Seeds, if produced, dispersed by water; intentionally cultivated by people

Low Risk Traits:

• Unarmed (no spines, thorns, or burrs)
  
• Requires full sun (may limit spread into forest ecosystems)
  
• Seed set in cultivation rare or absent
  
• Self-Incompatible
  
• Lack of seed production in the Hawaiian Islands limits risk of accidental or long-distance dispersal
