Family: Rubiaceae

High Risk Traits:

• Elevation range exceeds 1000 m at lower tropical latitudes. demonstrating potential environmental versatility
  
• Thrives in tropical climates
  
• Tolerates many soil types
  
• May form dense stands in native range
  
• Seeds dispersed by mammals and intentionally by people
  
• Seeds able to be stored for extended periods; May form a persistent seed bank or remain viable in fruits that persist on the tree for an extended period

Low Risk Traits:

• No reports of invasiveness or naturalization (with the possible exception of Doon Valley, India)
  
• Unarmed (no spines, thorns or burrs)
  
• Palatable to browsing animals
  
• Ornamental
  
• Not reported to spread vegetatively
  
• Slow-growing, and reaches maturity in 4+ years
  
• Relatively large, indehiscent fruit remain attached to the parent tree for an extended length of time, limiting the potential for inadvertent dispersal
